How to deploy to other Linux distributions

[2gud4u]

Hello community.-

I compile/link my game with the command gcc -o exename main.c -lraylib -lstdc++ on Linux, but i have sent my "exe" to another Linux user and he says he cant run it. Could someone tell me what im doing wrong in order for my "exe" to run in other Linux dristributions ? Thanks in advance !!!

i generally just statically compile raylib, its not a gigantic library...

Thank you !! could you provide a link or example on how to do that ? I got raylib from Linux os packages

@2gud4u The raylib by default is compiled static, i.e. you get libraylib.a that you use to link your app/game. Not sure how Cmake builds work, probably can build both shared and static. You didn't send the error, what is the actual problem, is it raylib, or maybe Glibc (if you compile on the latest Glibc you probably can not use it on older distros). What does ldd say for your binary?

Also, not sure why you are compiling main.c with GCC and then linking to stdc++. Is it a C or C++ project? The best way is to compile a fully static binary, Glibc will complain about that but the Musl toolchain actually recommends that you build the static binary. Such binary in theory should work on every distribution.

Anyway, doesn't look like a raylib issue, this is a general Linux question.

Hello @gen2brain yes i think its a raylib issue, here i cannot find libraylib.so.400 afther making a static compile on raylib, not saying its something wrong with raylib

Well, that is not static, you linked against the shared raylib .so library, so any Linux OS would need to have raylib installed as a shared library in order to use your app/game. .so is a dynamic/shared library, .a or archive is a static library.

[2gud4u]

Yes i have already run make install i had in the past raylib linux packages but i have removed them, could that be the cause ? if i do a locate libraylib.so this is my input

Huh, yes, you have some mix there, and yes, that is the cause. You have raylib installed as a shared library, not just in /usr/local but also in /usr/lib, you should not do that. Your package manager should be the only one that installs something in /usr/lib. Your custom stuff you don't want there, and raylib if you did not install via package manager is custom stuff.

It is your system, you are free to remove them all. You probably used a CMake build system before this, and it installed a shared library on your system. My suggestion is to remove all of that, especially those in /usr/lib. Then just compile the static raylib library with make/make install and use that instead.

[2gud4u]

Wow now it works the compile/link could i also now distribute my "exe" ???

[2gud4u]

Hello, when i distribute my exe they tell me they got this error message.-
./engine: /lib/x86_64-linux-gnu/libm.so.6: version GLIBC_2.35' not found (required by ./engine) ./engine: /lib/x86_64-linux-gnu/libc.so.6: version GLIBC_2.33' not found (required by ./engine)
./engine: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./engine)

It seems you removed some library conflicts but you are still compiling an executable that requires a shared library.

The only way to get a self-contained single-file executable is to rely only on static libraries and object files you have compiled.

You probably don't even need a make file for this, but a Linux/GCC expert will need to assist you in that.

One suggestion: Look at build-linux.sh in raylib/projects/scripts. There are comments that will help. Also raylib/projects/scripts/README.md. Start by copying build-linux.sh and core_basic_window.c into a folder of your own and use the script there. If you can get a core_basic_window that works, see how to adapt that setup for a project of your own.
