Not being any kind of 'autoconf' expert I can't really comment on whether this is the "right" thing to do ;), but I can verify (see below) that this does the appropriate thing on my system. > This is what pkg-config reports for > libnl3 on my development system: > > $ pkg-config --cflags libnl-3.0 > -I/usr/include/libnl3 $ pkg-config --cflags libnl-3.0 -I/usr/local/netacquire/platform/1_2_0a/toolchain/include/libnl3 I assume this is something that you can fix up in the configure script?
