If I sounded grumpy, it's because I'm tired of fixing people's code
so it is cross-compile-friendly.
pkg-config looked like One More Thing to Fix. It still kinda does.
I rather prefer autoconf macros for each library; they're more powerful.
One way pkg-config, and indeed configure scripts, fall down is that
they are inflexible when it comes to tailoring which shared libraries
you link to. This means you have to link to all of the shared libraries
a package provides, even if you only use a few of them. This shouldn't
be a problem, except that simply linking to a shared library seems
to pull it into memory, causing RAM waste that can be a killer on
I remain unconvinced that pkg-config is a good way to do things. I
suppose it might make things more convenient, but it might also
get in the way of making embedded systems work. I hope I'm wrong.
