I've a special/very slim version of debian. I want to install a custom version av zlib and I only want one zlib version on my system. Let's say I update zlib, then I also need to recompile and update (for example) openssh since it has zlib as one of its dependencies. Do I need to list those dependencies manually or is there a tool that will recompile all packages with reverse dependencies (something like bitbake does for yocto). How does upstream debian developer handle those cases?
If you install it as a .deb file via dpkg, I'd expect you'll be fine since those other packages are linked to the zlib package ... unless there are items you're removing that other packages will fail upon not getting. If that's the case, you probably want Alpine Linux or some other minimalist distro.
I'm a bit rusty, but I believe the process is something like this:
$ apt source zlib
$ cd zlib*/debian
[ make your changes in new diffs in the `patches` subdirectory]
$ dpkg-buildpackage -rfakeroot
This creates a .deb file and IIRC also installs it. If it doesn't also install it, then you can do that with a command like dpkg -i zlib*.deb
See also Debian's Building the Package documentation.
If all you need is a newer version of a particular package, you can add it from Debian Testing or Unstable in three steps:
1. Edit /etc/apt/sources.list or something in /etc/apt/sources.list.d/ to include
deb http://deb.debian.org/debian/ testing main non-free contrib
2. Edit /etc/apt/preferences or something in /etc/apt/preferences.d/ to include
Explanation: Don't use testing by default
Package: *
Pin: release a=testing
Pin-Priority: 1
3a. Install it manually:
$ sudo apt install -t testing zlib1g
3b. Alternatively, ensure it always installs from testing with another preferences stanza:
Explanation: Use zlib from testing
Package: zlib1g
Pin: release a=testing

I have GCC v9. But I'm trying to install a GCC 4.8.1 version to test a library compilation on that very old version of GCC.
The version is not available in the official Ubuntu repos,it is deprecated, but I've found it in other mirrors as told by the official GCC website. This one seems like popular one:
https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test
I have very little knowledge of linux package systems except for the basic. I want to keep both versions. So I should do this:
sudo apt -y install gcc-4.8.1 gcc-9
The reason why I want to use this command and not install it from the file, apart from the difficulty of doing that for me, is that I'm following a guide in order to have several GCCs on my system:
https://www.fosslinux.com/39386/how-to-install-multiple-versions-of-gcc-and-g-on-ubuntu-20-04.htm
When I add the url to the sources.list file seems like it is working.
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update -q
But when I try to call the install with gcc-4.8.1 or gcc-4.8 , or even gcc-4 the package doesn't exist.
Package gcc-4.8 is not available, but is referred to by another
package. This may mean that the package is missing, has been
obsoleted, or is only available from another source E: Package
'gcc-4.8' has no installation candidate
Also, I don't know if websites like these can be added to the repos list in order to find the package using APT:
http://www.netgull.com/gcc/releases/gcc-4.8.1/
[EDIT]
I downloaded the package from the website I linked. I have no idea how to install this by hand. If only I could find a repository that could help me with this... I have no idea how to make APT help me with the installation.
But I'm trying to install a GCC 4.8.1 version to test a library compilation on that very old version of GCC.
Developers have tools up their sleeve so they don't have to install dependencies and bloating their systems for every library (and every configuration of that library!) they want to try out and test.
Use docker. You could write for example a testing script, assuming your project uses make:
# test_my_lib_in_gcc-4.8.sh
#!/bin/sh
docker run -ti --rm -v $PWD:/project -w /project gcc:4.8 -u $UID:$GID sh <<EOF
make && make test
EOF
that will compile and test your application in using 4.8 gcc. Consider how easy it is to change gcc version - just change the number. You could test your library in gcc, in different versions, and using other compilers and on different distributions to make sure it works for others. If you're a developer of the library, write an automatized CI pipeline that would automatically test your application each commit in specific docker environment, using ex. https://docs.gitlab.com/ee/ci/README.html or https://travis-ci.org/ .
I am trying to build QT4 (porting from Redhat 5 to 7 with an upgraded gcc compiler) in RedHat 7 and I was getting an error saying X11/Xlib.h can't be found. Anyways, after doing some research most people said to install libX11-devel to get those x11 libraries. Since I am using an offline machine I can't do "apt-get" type commands and have to manually install RPMs. So, I went to my RH-7 installation DVD and got "libX11-devel-1.6.3-3.el7.x86-64" (I have 64 bit OS) and tried to install using "yum install libX11-devel-1.6.3-3.el7.x86_64" and I am getting dependencies errors. It's saying
...Requires: pkgconfig(kbproto)
...Required: pkgconfig(xcb)
...Requires: pkgconfig(xproto)
...Requires: pkgconfig(xcb) >= 1.1.92
So, here are my questions.
1) when it says "pkgconfig(kbproto)", is it saying find the "kbproto....RPM" and do a "yum install". In my dvd I only have "xorg-x11-proto-devel-7.7.13.el7.noarch.rpm". Do I have to somehow find "xorg-x11-proto......x86_64.rpm" since it's a 64 bit machine?
2) Is there a difference between "yum install" and pkgconfig "install"? Are there any other installation variants in Linux?
3)For an offline machine, Is there anyway I can get all the dependencies and install everything at once ?
4) Why is it saying "xcb" requires twice. If I just get a xcb...rpm version above 1.1.92 can I just install it once?
Before actually answering the questions, I am going to suggest to see if you can get the latest version of the packages. The packages on the installation DVD may be really out of date and contain known vulernabilities, and other bugs. Can you use yumdownloader - in an online environment - to download the latest version onto a separate DVD and use that as the installation source? See https://access.redhat.com/solutions/10154 for more information.
To answer the questions themselves:
Requires: foo can refer to a package foo or a "feature" foo. pkgconfig(kbproto) is a "feature" (or virtual requires). You can use yum/rpm to see what provides this. On my Fedora box, for example, rpm -q --provides xorg-x11-proto-devel shows that this package indeed provides pkgconfig(kbproto).
As for x86_64 vs noarch, it doesn't matter. noarch packages work everywhere. Other packages are restricted to the platform. So x86_64 only works on intel/amd x86 64-bit machines. Installing noarch should be fine in your case. If you only had a i686 package, though, that wouldn't be sufficient. You would have to find a x86_64 or noarch package.
Yes, there's a big difference between yum and pkg-config. They do completely different things. One is a system tool for installing RPM packages. The other is a tool for developers for using the right headers and compiler flags. If your concern is finding/installing RPMs, do not use pkg-config directly.
Do you have access to an online machine that can access the RHEL 7 yum repositories? On that machine, do something like this:
mkdir rhel7-packages
cd rhel7-packages
yum provides '*/X11/Xlib.h' # make a note of the package that provides this file. it's libX11-devel on Fedora here
yumdownloader --resolve libX11-devel # download libX11-devel and all dependencies not installed on the system
Then copy/install the RPMs on the machine without internet access.
It's probably printing out xcb twice because it's two different requirements. The unversioned requirement will be satisfied if you install any verison of xcb. The versioned requirement will only be satisfied if you install 1.1.92. If you install 1.1.92, it will satisified both the requirements.
1.
You have to resolve the dependency on the system where you are building your package. This means you need to have those dependencies installed, inclusing libX11-devel. To do that, download the RPMs manually from EL7 repos to local disk and run this:
$ mkdir -p /tmp/libX11_dep_rpms && cd /tmp/libX11_dep_rpms
# Download all dependencies from here. All your packages should be available here:
# http://mirror.centos.org/centos-7/7/os/x86_64/Packages/
# Then install
$ yum localinstall *.rpm
# After this you should be able to build your qt4 package, provided all dependencies are resolved. Otherwise, repeat the procedure for all dependencies
# If you can't download packages, then you need to create a FULL DVD ISO that will contain all packages.
2.
pkgconfig ensures that a requirement is coming from a particular build that provides a particular version of the library. Here are some detail.
3.
Get the Everything ISO from EL7.
4.
This has to do with the pkgconfig and library versions.
I'm using MSYS2, and I was expecting to be able to install flickcurl.
I tried installing as follows, but it seems that it can't find the file.
$ pacman -S mingw-w64-x86_64-flickcurl
error: target not found: mingw-w64-x86_64-flickcurl
Am I missing something here?
Probably your MSYS2 is outdated (think of it like Linux package manager which you update before installing stuff), you should run following commands and if you are asked to close terminal do it:
update-core - this one will fail if your MSYS2 is not very old, this is a good sign
pacman -Syu - you might have to repeat it until you see there is nothing to do; it updates your installed packages
pacman -S mingw-w64-x86_64-flickcurl
Those packages should be available after those steps:
$ pacman -Ss flickcurl
mingw32/mingw-w64-i686-flickcurl 1.26-1
Flickcurl is a C library for the Flickr API (mingw-w64)
mingw64/mingw-w64-x86_64-flickcurl 1.26-1
Flickcurl is a C library for the Flickr API (mingw-w64)
Commands explained:
update-core - used in the past to upgrade core packages, now removed since pacman does it
better
pacman -S <package_name> - checks local database for package
and installs it if it's found (will fail if there is no database or
it's outdated)
pacman -Su - compares installed packages to the
database searching for updates (will also fail if there is no
database or it's outdated)
pacman -Sy - downloads database with
available packages
pacman -Syu - downloads database and searches
for update, recommend way of upgrading
Final note:
MSYS2 doesn't support partial upgrades for the same reasons as Like Arch Linux. That means you should run pacman -Syu before installing package.
I'm trying to build some code on Ubuntu 10.04 LTS that uses OpenSSL 1.0.0. When I run make, it invokes g++ with the "-lssl" option. The source includes:
#include <openssl/bio.h>
#include <openssl/buffer.h>
#include <openssl/des.h>
#include <openssl/evp.h>
#include <openssl/pem.h>
#include <openssl/rsa.h>
I ran:
$ sudo apt-get install openssl
Reading package lists... Done
Building dependency tree
Reading state information... Done
openssl is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
But I guess the openssl package doesn't include the library. I get these errors on make:
foo.cpp:21:25: error: openssl/bio.h: No such file or directory
foo.cpp:22:28: error: openssl/buffer.h: No such file or directory
foo.cpp:23:25: error: openssl/des.h: No such file or directory
foo.cpp:24:25: error: openssl/evp.h: No such file or directory
foo.cpp:25:25: error: openssl/pem.h: No such file or directory
foo.cpp:26:25: error: openssl/rsa.h: No such file or directory
How do I install the OpenSSL C++ library on Ubuntu 10.04 LTS?
I did a man g++ and (under "Options for Linking") for the -l option it states: " The linker searches a standard list of directories for the library..." and "The directories searched include several standard system directories..." What are those standard system directories?
You want to install the development package, which is libssl-dev:
sudo apt-get install libssl-dev
Run:
apt-get install libssl-dev
All of these answers are very outdated and from when the package was still being developed. You can now just use the "normal" command listed below:
sudo apt install openssl
Edit: OP's question is poorly worded... after all, OpenSSL is a library itself, so I read his question too quickly before answering. The command above installs "normal" OpenSSL.
Toward the bottom of his question he mentions that make fails, suggesting he is compiling the package manually. And yes, even if you download the TAR ball, it will include all of the openssl and libssl files, which you can then make from.
What OP is really asking for is the OpenSSL Development Library, in which case you can first install OpenSSL using the above command, and then run this afterwards:
sudo apt install libssl-dev
More info: https://linuxtect.com/how-to-install-openssl-libraries-on-ubuntu-debian-mint/
I found a detailed solution here: Install OpenSSL Manually On Linux
From the blog post...:
Steps to download, compile, and install are as follows (I'm installing version 1.0.1g below; please replace "1.0.1g" with your version number):
Step – 1 : Downloading OpenSSL:
Run the command as below :
$ wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz
Also, download the MD5 hash to verify the integrity of the downloaded file for just varifacation purpose. In the same folder where you have downloaded the OpenSSL file from the website :
$ wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz.md5
$ md5sum openssl-1.0.1g.tar.gz
$ cat openssl-1.0.1g.tar.gz.md5
Step – 2 : Extract files from the downloaded package:
$ tar -xvzf openssl-1.0.1g.tar.gz
Now, enter the directory where the package is extracted like here is openssl-1.0.1g
$ cd openssl-1.0.1g
Step – 3 : Configuration OpenSSL
Run below command with optional condition to set prefix and directory where you want to copy files and folder.
$ ./config --prefix=/usr/local/openssl --openssldir=/usr/local/openssl
You can replace “/usr/local/openssl” with the directory path where you want to copy the files and folders. But make sure while doing this steps check for any error message on terminal.
Step – 4 : Compiling OpenSSL
To compile openssl you will need to run 2 command : make, make install as below :
$ make
Note: check for any error message for verification purpose.
Step -5 : Installing OpenSSL:
$ sudo make install
Or without sudo,
$ make install
That’s it. OpenSSL has been successfully installed. You can run the version command to see if it worked or not as below :
$ /usr/local/openssl/bin/openssl version
OpenSSL 1.0.1g 7 Apr 2014
How could I have figured that out for
myself (other than asking this
question here)? Can I somehow tell
apt-get to list all packages, and grep
for ssl? Or do I need to know the
"lib*-dev" naming convention?
If you're linking with -lfoo then the library is likely libfoo.so. The library itself is probably part of the libfoo package, and the headers are in the libfoo-dev package as you've discovered.
Some people use the GUI "synaptic" app (sudo synaptic) to (locate and) install packages, but I prefer to use the command line. One thing that makes it easier to find the right package from the command line is the fact that apt-get supports bash completion.
Try typing sudo apt-get install libssl and then hit tab to see a list of matching package names (which can help when you need to select the correct version of a package that has multiple versions or other variations available).
Bash completion is actually very useful... for example, you can also get a list of commands that apt-get supports by typing sudo apt-get and then hitting tab.
Another way to install openssl library from source code on Ubuntu, follows steps below, here WORKDIR is your working directory:
sudo apt-get install pkg-config
cd WORKDIR
git clone https://github.com/openssl/openssl.git
cd openssl
./config
make
sudo make install
# Open file /etc/ld.so.conf, add a new line: "/usr/local/lib" at EOF
sudo ldconfig
You want the openssl-devel package.
At least I think it's -devel on Ubuntu. Might be -dev. It's one of the two.
As a general rule, when on Debian or Ubuntu and you're missing a development file (or any other file for that matter), use apt-file to figure out which package provides that file:
~ apt-file search openssl/bio.h
android-libboringssl-dev: /usr/include/android/openssl/bio.h
libssl-dev: /usr/include/openssl/bio.h
libwolfssl-dev: /usr/include/cyassl/openssl/bio.h
libwolfssl-dev: /usr/include/wolfssl/openssl/bio.h
A quick glance at each of the packages that are returned by the command, using apt show will tell you which among the packages is the one you're looking for:
~ apt show libssl-dev

Go to the official website and download the source code for the version you need
Then unzip the update package and execute the following command
./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl -Wl,-rpath,/usr/local/ssl/lib shared
Because the default is to generate only static libraries, if you want dynamic libraries, add the "shared" option
make && make install

I've Redhat 7.2 running Cinnamon, and hate the docks provided, how come I can't resize the area a widgit is allocated? All apps are jammed into half the dock.
Drives me to compile cairo-dock from source as it isn't an ibm redhat blessed package.
cmake .. -DCMAKE_INSTALL_PREFIX=/usr
...
-- checking for module 'wayland-client>=1.0.0'
-- package 'wayland-client>=1.0.0' not found

so I find gtk version is 3.14.13-16.el7 using yum list installed "gtk*"
I downloaded gtk 3.4.4 and compiled it and follow the INSTALL provided, sudo make install, which completes with no errors
rerunning cmake gives me the same error, so I'm wondering if I had to remove 3.14? I'm not really sure how best to proceed and thought it best to get some advice. I'm not really in the mood to break things. Thanks for your time and consideration.
Calvin, I'm also IBMer and installed RHEL7.2 from IBM's image.
I could successfully download the sources and install Cairo Docker and respective plugins.
I followed the instructions in this page here:
Glx-Dock - Generic:Compilation
First, install all dependencies below from official IBM repository.
I used the same package names for the Fedora dependencies and some may NOT exist for RHEL. Therefore, some plugins won't be available by fetching dependencies from official repository only - but the Cairo Docker will work.
sudo yum install cmake make pkgconfig gcc gcc-c++ gettext glib2-devel\
cairo-devel librsvg2-devel dbus-glib-devel libxml2-devel libXrender-devel\
mesa-libGL-devel mesa-libGLU-devel pango-devel libXxf86vm-devel\
libXtst-devel libXrandr-devel libX11-devel libcurl-devel gtk3-devel\
vte3-devel lm_sensors-devel libxklavier-devel libexif-devel\
libetpan-devel gnome-menus-devel alsa-lib-devel libical-devel\
upower-devel libzeitgeist-devel
Untar the packages and build with the commands described there except that you need to force the lib64 in both main and plugin builds with:
cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DFORCE_LIB64=yes
