[linux-audio-user] jack_fst build question

Hi, I got past my Wine problems today, finally got libfst built successfully and was next trying to build jack_fst. (I hope this is worth the effort...) ;-) However, it's not happy with libfst: mark@flash jack_fst-1.2 $ ./configure checking for a BSD-compatible install... /bin/install -c checking whether build environment is sane... yes <SNIP> checking for libfst >= 1.3... Package libfst was not found in the pkg-config search path. Perhaps you should add the directory containing `libfst.pc' to the PKG_CONFIG_PATH environment variable No package 'libfst' found configure: error: Library requirements (libfst >= 1.3) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them. mark@flash jack_fst-1.2 $ What is the pkg-config search path? How's a user like me supposed to adjust this? I've not seen this problem for a long, long time and I've never seen it on a Gentoo box. libfst is installed: mark@flash jack_fst-1.2 $ slocate libfst /usr/local/lib/pkgconfig/libfst.pc /usr/local/lib/libfst.so /home/mark/data/fst-1.5/libfst.pc.in /home/mark/data/fst-1.5/fst/libfst.spec.c /home/mark/data/fst-1.5/fst/libfst.spec.o /home/mark/data/fst-1.5/fst/libfst.so /home/mark/data/fst-1.5/libfst.pc mark@flash jack_fst-1.2 $ and I've run ldconfig just for completeness but it still doesn't allow this to build. Thanks, Mark
