Wanted to let you know that version 0.40 compiles on Mac.
Details: Mac OS 10.4.11; Xcode 2.5; PPC G5
I pretty much followed your directions, however:
I had to change the configure line to:
./configure —prefix=/opt/local PKG_CONFIG_PATH=../liblqr-1-0.1.0
where PKG_CONFIG_PATH points to the directory that liblqr was downloaded to (the directory that contains the file "lqr-1.pc")
Works Great!!! Thanks for making this available.
