Consider, GCC uses multilibs at compile-time/link-time. Somewhat oversimplified, multilibs changes GCC's library search paths by appending a relative directory to library-directories (-L). So, if pkgconfig wants to be flexible (multilibs can change over time) and portable (pkg-config is not tied to native compilation, consider cross-compilation), it (a) should check if it is being used with a multilib enabled GCC and (b) if (a) applies, could adopt GCC's multilib library search-path expansion to be able to automatically expand PKG_CONFIG_PATH. > e.g. the i386-on-x86_64 developer just removes the 64 bit paths and > voila, /usr/bin/pkgconfig does the right thing for i386. And the > normal paths take care that /usr/bin64/pkgconfig manages 64 bit libs. The correct API would be to take multilib flags into account: E.g. something similar to pkg-config CC=gcc CFLAGS=-m32 .... on i386/x86_64 platforms or pkg-config CC="avr-gcc" CFLAGS="-mavr5" for an avr cross-compiler targetting avr5 multilibs > Clean separation of archs. This is run-time separation, trying to map link-time separation into run-time separation. This works as long as the number of multilibs is small, but becomes very unhandy, when using pkg-config for systems which have many multilibs (such as many embedded systems).
