sdl2_net undefined reference to `inet_addr` #324

I wanted to build a switch executable and use sdl2_net from the switch portlib and got following linker error:

/opt/devkitpro/devkitA64/bin/../lib/gcc/aarch64-none-elf/13.2.0/../../../../aarch64-none-elf/bin/ld: /opt/devkitpro/portlibs/switch/lib/libSDL2_net.a(SDLnet.o): in function `SDLNet_ResolveHost':

You're not adding the libs you need to link. If you're using stock Makefiles then add `$(PREFIX)pkg-config --cflags SDL2_net` to CFLAGS and `$(PREFIX)pkg-config --libs SDL2_net` to LIBS. If not then post on the forums instead with details of the build system you're using.

Sorry for bothering you. I'm new to Makefiles and your suggestion fixed it.
