Making libos dependant on gcc is a very big problem, i dont think ill agree
Locating a header with the gnu toolchain (your solution needs it to be used
for all applications using libos, mine just needs it during libos install)
just parse the output from
echo '#include <sys/socket.h>' | cpp -M
or look at the directories from
or even take the first sys/socket.h from
echo '#include <sys/socket.h>' | cpp
And if you dont know how to make a symlink, make a copy.
libos has to be reinstalled anyway if headers change ...
