Compiling GLFW on old linux

BlackRain · May 13, 2024, 8:49am

Hi! I’m trying to compile GLFW on a very outdated linux distro (which support is over) - for very old notebook.
My system is: Linux Mint 17.1 Rebecca (based on Ubuntu 14.04.6 LTS, Trusty Tahr).
I’m doing this:

git clone https://github.com/glfw/glfw.git
cd glfw/
cmake -S ~/src/glfw -B ~/src/glfw/build -D GLFW_BUILD_WAYLAND=0 -D BUILD_SHARED_LIBS=ON -D GLFW_BUILD_X11=ON
cd build
make

Getting errors like this:

[ 24%] Built target glfw

I’m don’t know how to attach a full log to this post.
What’s wrong with compiling?

dougbinks · May 13, 2024, 9:18am

Those appear to be warnings rather than errors, and the target boing appeared to build. If they are just all from linmath.h then this is only used in the examples, so the GLFW libraries should build without warnings.

You could potentially look into updating your compiler, as the warnings look incorrect to me.

BlackRain · May 13, 2024, 9:36am

ok, thanx, i will try to do this

Papasot · May 16, 2024, 5:37pm

Most probably a compiler (or glibc?) issue. I would recommend switching to an operating system that’s more recent and therefore has a recent glibc and compilers. I use GLFW in two old netbooks without any issues.

There are some lightweight distributions for such old machines. I am using antiX which is designed mainly for old computers, while still providing very recent versions of compilers and libraries. Void is also a very good choice (not specifically for old computers but works well in oldies anyway). I’m sure there are others too, but those two are the ones I have tried in 15+ years old 32-bit netbooks with 1 Gb of RAM, and they work pretty well. You can either compile GLFW yourself, or use their package manager (both distributions have GLFW available in their repositories, and it’s usually up-to-date).

BlackRain · May 24, 2024, 7:12am

Thanks. I will try it later.

I have updated my compiler to version 14.1.0. Not sure i did it correctly. Still getting the same errors anyway.

dougbinks · May 24, 2024, 5:29pm

You may need to remove your cmake build directory and re-run cmake to create new make files with the new compiler.

You should see output when running cmake like:

-- The C compiler identification is GNU 11.4.0
-- The CXX compiler identification is GNU 11.4.0

With this my GLFW source code builds fine.

BlackRain · May 25, 2024, 6:22am

I’ve already done this a few times. The result is the same. It still prints the same warnings. Something is wrong

Hmm… I see a different output:

-- The C compiler identification is GNU 4.8.3

The -- The CXX compiler... line is missing.
Why is it? Maybe my cmake parameters is wrong? How to check it?
…
I realized my mistake. My promlem is that i have two different compiler versions on my system.
/usr/local/bin/gcc - version 14.1.0
/usr/bin/gcc - version 4.8.4
When i type gcc in my terminal, it will launching gcc from /usr/local/bin. I assume that CMAKE usiing gcc from /usr/bin by default. I don’t know how to change this behavior yet.
So i have tryed to add -D CMAKE_C_COMPILER=/usr/local/bin option to the command line (is this correct? ). The output is changed to this:

$ cmake -S ~/src/glfw -B ~/src/glfw/build -D GLFW_BUILD_WAYLAND=0 -D BUILD_SHARED_LIBS=ON -D GLFW_BUILD_X11=ON -D GLFW_BUILD_TESTS=OFF -D CMAKE_C_COMPILER=/usr/local/bin

Bingo! I found a right command for my system. There is:

$ sudo cmake -S ~/src/glfw -B ~/src/glfw/build -D GLFW_BUILD_WAYLAND=0 -D BUILD_SHARED_LIBS=ON -D GLFW_BUILD_X11=ON -D GLFW_BUILD_TESTS=OFF -D CMAKE_C_COMPILER=/usr/local/bin/gcc -D CMAKE_CXX_COMPILER=/usr/local/bin/g++ -D CMAKE_LIBRARY_PATH=/usr/lib/i386-linux-gnu
$ cd build/
$ sudo make
$ sudo make install

It’s compiling and installing without any errors/warnings.
Thanx to all for help!
