The compile errors below have me stumped. I successfully compiled and installed LADCCA 0.4.0 and other dependencies. After configuring Jack-Rack, I had to hack the Makefiles because the configure got the locations of the xml ..../lib and ..../include directories wrong. Strange, had the same problem with the makefiles for LADCCA. Finally my 'make' for jack-rack led to this: Making all in src [....] source='main.c' object='jack_rack-main.o' libtool=no \ depfile='.deps/jack_rack-main.Po' tmpdepfile='.deps/jack_rack-main.TPo' \ depmode=gcc3 /bin/sh ../depcomp \ gcc -DHAVE_CONFIG_H -I. -I. -I. -DXTHREADS -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/X11R6/include -I/usr/include/atk-1.0 -I/usr/include/pango-1.0 -I/usr/include/freetype2 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/local/include -I/usr/local/include/ladcca-1.0 -I/usr/local/include -I/usr/include/alsa -I/usr/include/libxml2 -DPKGDATADIR=\"/usr/local/share/jack-rack\" -DPIXMAPDIR=\"/usr/local/share/pixmaps\" -DDTDDIR=\"/usr/local/share/dtds\" -DG_DISABLE_DEPRECATED=1 -DGTK_DISABLE_DEPRECATED=1 -DGDK_DISABLE_DEPRECATED=1 -DGDK_PIXBUF_DISABLE_DEPRECATED=1 -DGNOME_DISABLE_DEPRECATED=1 -g -O2 -c -o jack_rack-main.o `test -f 'main.c' || echo './'`main.c main.c: In function `main': main.c:212: `CCA_Use_Jack' undeclared (first use in this function) main.c:212: (Each undeclared identifier is reported only once main.c:212: for each function it appears in.) main.c:214: `CCA_Use_Alsa' undeclared (first use in this function) make[2]: *** [jack_rack-main.o] Error 1 Any troubleshooting hints would be welcomed.
