Where can I find libraries for GCC in linux?

Question

C++ / C#

Hello
Let's say I installed some library. Where to look for its location, so that later you can tell the compiler so that the program builds successfully?

Answer 1

Libraries are usually installed in /usr/lib/, /usr/local/lib and their subfolders. Usually these paths are already in LD_PATH, so it's enough to specify -l<libname>.
Libraries are also often installed along with the pkg-config configuration, so you can use it like this:

gcc -c file.c `pkg-config --cflags <libname>`
gcc file.o -o file `pkg-config --libs <libname>`
