It seems that upon trying to compile SDL_image on Debian Stretch, I am getting a linker error. I am not sure why, but I think it could be because of GCC 5?
It seems to only effect 64 bit.
I tried to file a bug report, but it seems that I am not getting the confirmation email to create an account…
I am compiling with
export INSTALLDIR=/opt
./autogen.sh
./configure --prefix=$INSTALLDIR --libdir=$INSTALLDIR/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)
make
and I am getting the following output
config.status: executing depfiles commands
