I'm having a hard time trying to install Qt on linux. I downloaded the .run file on the website and installed Qt. However, when I try to compile the default Hello World project using Qtcreator, I get the following :
error cannot find -lGL
I was able to solve the problem by issuing the command :
sudo apt-get install libqt4-dev
But, I'm not satisfied with the solution as I want to use Qt5 and the name of the lib I downloaded implies version 4. Can someone explain what is going on and tell me if my solution is correct? If not, what should I do to get a working Qt on Linux.
Additional question
The correct answer, as provided by LtWorf, was to install libgl-dev. For future problems of this sort, can someone tell me how I should have guessed that I had to download this particular library? And why are there some libs with -dev at the end? What do they provide?
Well it is trying to link with libgl and doesn't find it. You should install libgl-dev.
-l is a linker option, it tells the linker to use a certain library.
For example you can have -lmagic meaning that you want to use libmagic.
Normally all libraries are called libsomething, and on debian you will find 3 packages called:
libsomething
libsomething-dbg
libsomething-dev
The 1st one is the library, the second one is the library compiled with the debug symbols, so you can make sense of stacktraces more easily, and the final one is the development package, it contains the .h files so you can link to the library.
sudo apt-get install libgl-dev
On Fedora 17, I did:
sudo yum install mesa-libGL-devel
Do you have libgl-dev installed? If not install it and it should work.
Those other posters are correct, but on some systems, the lib to install is named differently. I just dealt with a 32bit Ubuntu 14.04.5 LTS system, and libgl-dev was not available.
Instead, I needed to install the libgl1-mesa-dev package via:
sudo apt-get install libgl1-mesa-dev

I am using Ubuntu 18.04
I built a mips cross-compiler using buildroot, but when I tried to test whether it would work,I got this message
/home/daisy/repos/repo/buildroot/output/host/bin/../libexec/gcc/mipsel-buildroot-linux-uclibc/9.3.0/cc1: error while loading shared libraries: libmpfr.so.6: cannot open shared object file: No such file or directory
I searched for solutions , one of which said this:
sudo pacman -S mpfr
Well , my Linux isn't archlinux, this didn't work for me.
somebody please tells me how to deal with it.
The above suggestions of installing libmpfr on your host system are wrong. Buildroot is supposed to have build libmpfr, it should be present in host/lib, and picked up by the cross-compiler by virtue of it having a proper RPATH. If it doesn't work, we need to figure out why, but the correct thing is not to install libmpfr on your host system.
In Ubuntu, apt command (Advanced Packaging Tool) is used for performing such functions as installation of new software packages, upgrade of existing software packages, updating of the package list index, and even upgrading the entire Ubuntu system.
Try this command :-
sudo apt-get update
sudo apt install libmpfr6
This will install shared libraries: libmpfr.so.6 to your Ubuntu system.
Hope It Helps !
I'm trying to install a library that uses gmp and am running the ./configure on it.
So far, I've gotten past several snags, such as requiring gcc, g++, and m4 by using:
yum install gcc
yum install gcc-g++
yum install m4
Now I'm getting this error:
checking for the GMP library version 4.1.3 or above... no
configure: error: Cannot find GMP version 4.1.3 or higher.
GMP is the GNU Multi-Precision library:
see http://www.swox.com/gmp/ for more information.
When compiling the GMP library, do not forget to enable the C++ interface:
add --enable-cxx to the configuration options.
As such, I tried both installing and updating gmp using yum:
yum install gmp
yum update gmp
Install tells me it's already installed and is v. 5.1.2
Updating says there's nothing to update.
I went to the gmp site and it is currently v. 6.0.0
I downloaded it and ran configure (using --enable-cxx), make, and make install.
Yet, nothing has changed. It still says I have v. 5.1.2 and the configure for the library still says it can't find 4.1.3 and above / try enabling c++.
The gmp files (such as gmp.h) are being placed in /usr/local/lib and /include
I've been at this for hours without any progress. I'm rather new to linux so I imagine there's something I just don't know about.
Am I not installing 6.0.0 correctly to overwrite the already installed one?
Or is there a way to reinstall the original with the c++ option?
Any help would be appreciated. Thanks.
dnf install gmp-devel resolved this for me on rhel
When you manually install something, as you have, it doesn't get installed in the normal /usr/lib directory and therefore it doesn't overwrite it. This is a good thing. In general, you shouldn't mess with files installed by the package manager. (Except in the case that they are config files that are meant to be edited.)
When you install manually, it is installed to /usr/local/lib. Fortunately, GCC and other compilers don't care which directory something is installed in, they will find it (when it's in standard places like /usr/* or /usr/local/*).
Just include the C++ header and add the correct -l library flag.
I figured it out.
Under the --help section of the ./configure for the library I was trying to install, there was actually a feature just for this:
--with-gmp-include=DIR
--with-gmp-lib=DIR
Using these, I was able to get it to install.
Thanks for the help.
I think I was too focused on trying to update the system install of gmp.
I have R 3.4.1.1 on my computer (Linux).
I want to install R version 2.14.1 since the package Rmosek does not work in newer version.
I have downloaded the R-2.14.2.tar.gz from Cran.
My problem is that I do not understand the INSTALL instructions,
It says to unpack the R sources and go to the top directory and issue the following commands:
./configure
make
I wrote the following in a terminal:
tar -zxvf R-2.14.2.tar.gz
cd Downloads
cd R-2.14.2
./configure
It is run but finally gives the error:
configure: error: --with-x=yes (default) and X11 headers/libs are not available
make
and it gives the error:
make: *** No targets specified and no makefile found. Stop.
The file explains that If my make is not called `make', set the environment variable MAKE to
its name, and use that name throughout these instructions. I really do not know how I should do it since I am new in Linux.
Is there any other instruction with more explanation? I would be very thankful in advance for your help or guidances.
Regards,
Shima.
This is answered in detail in the R installation and administration guide,
http://cran.r-project.org/doc/manuals/R-admin.html#Essential-programs-and-libraries
Unless you do not want to view graphs on-screen (or use a Mac) you
need ‘X11’ installed, including its headers and client libraries. For
recent Fedora distributions it means (at least) RPMs ‘libX11’,
‘libX11-devel’, ‘libXt’ and ‘libXt-devel’. On Debian we recommend the
meta-package ‘xorg-dev’. If you really do not want these you will need
to explicitly configure R without X11, using --with-x=no.
More specifically, for Ubuntu, this means:
sudo apt-get install xorg-dev
and then proceed with compiling and installing R.
If you have to compile R in your system and install you should have libx11-dev package installed in Ubunut.Can you check whether this package is installed or not.
Otherwise you can configure the source with this option as a work around solution only in the case if you are not going to use any GUI functionality in R.
./configure --with-x=no
You need to install these libraries:
sudo apt-get install -y libx11-dev \
xorg-dev \
libcurl4-openssl-dev
Then run:
./configure
make
And then it should work.
Good luck!
recently i tried to install oracle on my linux with apt (I never used yum before) using fast manual:
http://www.oracle.com/technetwork/articles/servers-storage-admin/ginnydbinstallonlinux-488779.html
And after command:
sudo yum install oracle-rdbms-server-11gR2-preinstall
I got error:

There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named yum
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.6.6 (r266:84292, Jul 10 2013, 06:42:56) [GCC 4.4.7 20120313 (Red Hat 4.4.7-3)]
If you cannot solve this problem yourself, please go to the yum faq at: http://wiki.linux.duke.edu/YumFaq
So it seems like yum install in my system new libraries but didn't link it correctly? I dont know what do in this moment because it seems like armagedon on my ubuntu...
Does this mean you're on ubuntu and tried to install rpm packages using yum? The manual you used is for Oracle Linux 6, why would you try that on ubuntu?
rpm packages are not compatible with debian based systems like ubuntu, which use deb packages. So you've probably screwed your system big time, overwriting important system libraries with incompatible ones.
If apt-get is still working, then you can try to reinstall (apt-get --reinstall install) the equivalent libraries to the ones mentioned in the install manual you linked to - naming isn't always the same for rpm and deb packages. dpkg -l should help you see which the correct installed libraries are. I'd start with the C libraries (libc) etc.
But if apt-get is screwed also, then you'd need to download the packages manually from an ubuntu mirror and install them using dpkg, but I think a reinstall (or restore from backup if you have one) would be the best option.
I am trying to install roccc 2.0. I have installed required packages. Now while installing it, it is giving me this error:
/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file or directory
I searched for gnu/stubs-32.h and came to know, for Linux 64-bit its in glibc-devel and for Linux 32-bit, its in libc6-dev-i386.
I am using Linux 32-bit: i386 GNU/Linux, but couldn't get the lib required to resolve this error.
Can somebody please help me out?
If your Linux distro is Redhat based (Fedora/CentOS/RHEL):
yum install glibc-devel.i686
References
Original post answer solved this problem RHEL x64
Header file gnu/stubs-32.h is under /usr/include/i386-linux-gnu/ but the install script tries to find it in /usr/include/, try this quick fix to complete the installation:
sudo ln -s /usr/include/i386-linux-gnu/gnu/stubs-32.h /usr/include/gnu/stubs-32.h
After installation is finished, you can delete the link.
The package name keeps on changing, just do a
yum list glibc-devel
to find out current package for 32 bit. In my case it only listed 2 packages one for 32 bit and one for 64 bit. I just installed the 32 bit using
yum install glibc-devel.i686
Install 'glibc-devel' package, or whatever it called in your distro. You may also need to install ia32-libs lib32z1-dev lib32bz2-dev (names could be different in your distro).
The script is trying to get stubs-32.h from /usr/include/ where it is not found. To solve this you have to add an "include" path (by default it is /usr/include) like this:
C_INCLUDE_PATH=/usr/include/i386-linux-gnu/
export C_INCLUDE_PATH
OR
export C_INCLUDE_PATH=/usr/include/$(gcc -print-multiarch)
You can visit Error "gnu/stubs-32.h: No such file or directory" while compiling Nachos source code for additional reference.
If on a Red Hat distro such as Fedora/CentOS/RHEL you can do the following to find out what package provides a given file:
$ repoquery -qf */stubs-32.h
glibc-devel-0:2.17-260.el7.i686
And then install it:
$ sudo yum install -y glibc-devel-0:2.17-260.el7.i686
