Injection problem [LINUX]

[bruhmoment21]

When i try to inject this into csgo i get signal 11 (segmentation fault i think). I even made a different project memory class only and pollEvent + swapWindow.

System: Ubuntu 20.04 Compiling with g++ and using c++17(no build errors).

I'm not getting get my couts printed into the terminal.

Try injecting using gdb.

Try injecting using gdb.

My game crashes when using gdb. Below is what logs into console after injecting.

No minidump written, nothing to upload.

Check what dlsym() returns.

[bruhmoment21]

Both returned 0.

Maybe you're injecting too early - wait until you see the main menu and then inject. Could you show your CMakeLists.txt/Makefile?

Looks like you're not linking properly against SDL2. Try adding this to your CMakeLists:

target_link_libraries(GOESP SDL2 GL)

Still not fixed.

[bruhmoment21]

Fixed by replacing RTLD_NEXT with this var: void* sdl_library = dlopen("libSDL2-2.0.so.0", RTLD_LAZY);
