The sdl2_net package provides a cross-platform networking library.
Install SDL2_net by running the following commands:
./configure --prefix=/usr \
--disable-static \
--disable-sdltest \
--disable-examples &&
make
Now, as the root user:
make install
--disable-static: This
switch prevents installation of static versions of the libraries.
--disable-sdltest
--disable-examples: These parameters disable linking
against a library that was deleted in SDL2.
