GCC

some tips when i trying compile opengl programs in conda

• g++ -I/home/hongy19/miniconda3/envs/opengl/include/ : include *.h
• g++ -L/home/hongy19/miniconda3/envs/opengl/lib   :add folder of *.so for link(ld)
• g++ -lglfw: use libglfw.so for link(ld)
• LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/hongy19/miniconda3/envs/opengl/lib ./a.out: add library search path for dynamic *.so 
• static compile
• -static compile for static link need *.a and *.o library and *.so doesn't work for static compile, see link.  The error of following code is due to missing of *.a or *.o even *.so existed.
  

(opengl) hongy19@WSL opengl$ gcc glfw-1.cpp -static -lglfw -lGL
/usr/sbin/ld: cannot find -lglfw: No such file or directory
/usr/sbin/ld: cannot find -lGL: No such file or directory
collect2: error: ld returned 1 exit status
