Order seems to be wrong, these -l's are from EXTRA_LIBS defined by configure.ac but they are threated as LDFLAGS instead of LDADD by looks of it. After trying few modifications with libs/midi++/Makefile.am and libs/pbd/Makefile.am I couldn't figure way to change this order.. some help would be appericiated. EXTRA_LIBS contains XML_LIBS which is needed by libs/pbd, and AUDIO_LIBS which is needed by libs/midi++. i686-pc-linux-gnu-g++ -I/usr/lib/sigc++-1.2/include -I/usr/include/sigc++-1.2
