I tired to compile tun.ko linux kernel version 3.0.21+ for my older embedded system. Tried install jessie on my VM so i can use gcc4.8/gcc4.9, but no tun.ko built in my drivers/net after i hit make modules. I even use make allyesconfig and retry make modules but no luck. I just want tun.ko armhf for kernel 3.0.21+, cant find the binary so i want build it, but still no luck for both.

im trying to solve this issue for a few days now and i cant find any solution.
I got myself an Atmega88A and i want to program it on fedora.
I tried to program C with gcc and that went well. But as i tried to include the avr/io.h, i always get the failure that it didnt found anything. I tried to get the new version of gcc, but that gives me an error too. Would it be enough to just download the avr/io.h library and implement it somewhere in my files? or is there any way to download this all together, including also all the other libraries that i need (e.g. util/delay.h)
You need to use a version of GCC that is specifically built to target AVR chips, you cannot just use the normal gcc executable for your system because it will produce the wrong kind of program. If you download a correctly-configured toolchain, then lines like #include <avr/io.h> should work automatically because the toolchain's default include search paths will be set up properly.
Many Linux distributions provide an avr-gcc package that you can just install with your package manager, including Fedora. You might have to install the avr-libc package to get the avr/io.h header.
If that doesn't work for some reason, you could try downloading Microchip's official AVR toolchain from this page:
http://www.microchip.com/avr-support/avr-and-arm-toolchains-(c-compilers)
What fixed this problem for me was this missing package: avr-gcc-c++. Running the command:
dnf install avr-gcc-c++
fixed it.
I have been working with Linux kernel, compiling and inserting modules, in my custom kernels. Previously I had Ubuntu where I had been working with my custom kernel and all the commands for compiling and installing kernel worked like a charm once I had installed all the required libraries.
Now I have switched over to Fedora 20, here I want to install my custom kernel and for that I downloaded all possible kernel tools, namely, Kernel Development Kernel Tools these are group installs and other libraries that I downloaded were ia32 libraries (as I am working on 64-bit OS), kernel-devel package. Still I am not able to work with make-kpkg command. It says bash: make-kpkg: command not found....
I googled out and did everything I could.
Can anyone get me out of this trouble?
make-kpkg is a Debian kernel packaging tool. It does not exist on RHEL family distributions, such as Fedora.
Please refer to the Fedora documentation page "Building a custom kernel" for the correct procedure. (I have not reproduced it here as it is rather long, and I'm not sure how far you may have gotten.)
The make-kpkg tool is part of the 'kernel-package' package on Debian systems. It is a Debian tool to produce debian package files. Ubuntu is based on Debian and has this tool. However, Fedora uses a different system to manage packages. So, make-kpkg would not be available on Fedora.
I have a project that runs on Debian and uses many packages provided from the Debian repositories.
Because of demand, I've looked into porting the project to CentOS, but found that many of the packages I require are completely missing - at least 10 dependencies would have to be compiled manually at install time on the users machine.
My question is, what is the best way to create an installer for the user's machine? Should I use automake tools (with the standard ./configure, make, make install), to compile the required libraries, or is this a non-standard approach. Note that my app doesn't actually need to be compiled since it is written in Python, so is it weird to do a "make", when you're not compiling your own app?
Should the configure script just warn the user that package X is missing, and let them handle the rest?
Should I roll my own dependency checker by runng pkg-config manually a few times for each library required, and exit if something is missing?
I'm quite new to this, so any tips to get me moving in the right direction are appreciated.
Edit: I am familiar with RPM and yum for red hat base distros, but CentOS is missing many multimedia packages that I require. An example of one of my package dependencies is "liquidsoap" which is a programmable audio engine: http://savonet.sourceforge.net/
This is available on Debian, but not Redhat/Centos
See this link on CentOS package management.
http://wiki.centos.org/PackageManagement/Yum
CentOS is redhat based and does not use .deb packages by default. However apt package management has been ported to tons of platforms, you may be able to use a port for centOS
If you use YUM whatever packages you need will be there for your application as redhat distros need all the same things that any other distro does.
EDIT: To get the details out of comments
Packages not available on the target platform either have to be built (possibly as a port) on the target platform and then shipped in the ported package (in this case YUM), or code needs to be modified and forked to use packages which already are available on the target platform. The choice depends on which is worse, or which is even possible given your constraints.
I'm attempting to build a binary package that can be run on multiple Linux distributions. It's currently built on Ubuntu 10.04, but it fails on Ubuntu 8.04 with the following error:
./test: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by ./test)
./test: /usr/lib/libstdc.so.6: version `GLIBC_2.11' not found (required by ./test)
What's the preferred way to solve this problem? Is there a way to install an old glibc on a new box and build against it, or do I have to build on an old distribution? And if I build against an old glibc, will it work on a new glibc?
Or, alternatively, are there just some handy compiler flags or packages I could install to solve the problem?
The best solution I've found is to install a virtual machine running Debian stable, and build on that. Debian stable is old enough that any packages built with it will run on any other Debian-based distribution like Ubuntu. You may have to work around non-critical bugs that have been fixed in later versions of various software but not backported to Debian stable.
If you really want to make sure it runs on every recent distribution, you might also consider statically linking against a libC you select. However you may then still run into problems if you use features that are only provided by newer kernels (newer system calls e.g.).
Can I install an older version of gcc/g++ (4.1.3) on the latest Ubuntu (which comes with 4.4.3) and use it to compile a .so which should run on CentOS? The binary compiled with the Ubuntu version of gcc fails to load on CentOS because of missing imports (GLIB_2_11, ...). I need C++ (including exceptions), so I can't just statically link against glibc, which I already tried.
Can I install the older gcc without removing the newer one? How do I go about the libs required by the older gcc?
I'm currently developing code in CentOS, but it's such a pain to use. I really want to move to an Ubuntu desktop.
g++-4.1 is available for Ubuntu; just run apt-get install g++-4.1 then run g++-4.1 instead of g++. However, simply using an older compiler may not fix all of your library issues.
Like Joachim Sauer said, your best bet is to do your development on Ubuntu then do the final compilation on CentOS.
Even though you're using C++, static linking should still be an option. (However, you're much better off compiling on CentOS and using dynamic linking.)
Edit: A virtual machine is the most straightforward way to build on CentOS, but if you want to avoid the memory and CPU overhead of running a VM and don't care about differences between Ubuntu's and CentOS's kernel, then you can create a subdirectory containing a CentOS or Fedora filesystem and chroot do that to do your builds. This blog posting has details.
