Hi there,I'm using fst.1.7 for launch the vst's with very succes,thanks to everyone who did this posible,it works really greate. At the readme file included in the tarball I read this: / 5) build ardour with fst support. copy the SC* files from the ardour directory into your ardour build path. and the build ardour like: scons VST=1 VSTPATH=/path/to/compiled/fst-1.7/ I tried to compile ardour in that way,copied the fst-1.7/ardour/SConstruct to the build directory,and run scons with this options: /supertux@sid:~/proceso/ardour/ardour-0.99$ scons BUILD_SSE_OPTIMIZATIONS=1 USE_SSE_EVERYWHERE=0 VST=1 VSTPATH=/home/supertux/vst/fst-1.7/ PREFIX=/usr KSI=no DEBUG=yes/ But get some error messages:/ scons: Reading SConscript files ... 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 ...... .... libs/ardour/audioengine.cc:32:17: error: fst.h: No such file or directory libs/ardour/audioengine.cc: In function 'void _thread_init_callback(void*)': libs/ardour/audioengine.cc:87: error: 'fst_adopt_thread' was not declared in this scope scons: *** [libs/ardour/audioengine.o] Error 1 scons: building terminated because of errors./ This is the ls -l output of fst-1.7 dir /supertux@sid:~/proceso/ardour/ardour-0.99$ ls -l /home/supertux/vst/fst-1.7 total 292 drwxr-xr-x 3 supertux supertux 4096 2005-11-19 02:29 ardour -rw-r--r-- 1 supertux supertux 9928 2005-05-21 19:43 audiomaster.c -rw-r--r-- 1 supertux supertux 3944 2005-11-20 16:35 audiomaster.o -rw-r--r-- 1 supertux supertux 18009 2005-11-13 19:37 COPYING -rwxr-xr-x 1 supertux supertux 695 2005-11-20 16:35 fst -rw-r--r-- 1 supertux supertux 411 2005-02-01 23:34 fst.c -rw-r--r-- 1 supertux supertux 696 2005-02-01 23:34 fstconfig.c -rwxr-xr-x 1 supertux supertux 112483 2005-11-20 16:35 fst.exe.so -rw-r--r-- 1 supertux supertux 2519 2005-02-01 23:34 fst.h -rw-r--r-- 1 supertux supertux 6522 2005-10-16 07:59 fstinfofile.c -rw-r--r-- 1 supertux supertux 5480 2005-11-20 16:35 fstinfofile.o -rw-r--r-- 1 supertux supertux 1304 2005-11-20 16:35 fst.o -rw-r--r-- 1 supertux supertux 6360 2005-11-19 01:09 gtk.c -rw-r--r-- 1 supertux supertux 5888 2005-11-20 16:35 gtk.o -rwxr-xr-x 1 supertux supertux 7122 2005-02-01 23:10 install-sh -rw-r--r-- 1 supertux supertux 789 2005-02-01 23:42 jackvst.h -rw-r--r-- 1 supertux supertux 7604 2005-05-21 20:21 jfst.c -rw-r--r-- 1 supertux supertux 5000 2005-11-20 16:35 jfst.o -rw-r--r-- 1 supertux supertux 2962 2005-11-19 02:15 Makefile -rw-r--r-- 1 supertux supertux 1251 2005-11-19 02:26 README drwxr-xr-x 3 supertux supertux 4096 2005-11-20 16:35 vst -rw-r--r-- 1 supertux supertux 5818 2005-05-21 20:23 vsti.c -rw-r--r-- 1 supertux supertux 2508 2005-02-01 23:34 vstinfo.c -rw-r--r-- 1 supertux supertux 3628 2005-11-20 16:35 vsti.o drwxr-xr-x 9 supertux supertux 4096 2005-11-20 16:35 vstsdk2.3 -rw-r--r-- 1 supertux supertux 11559 2005-11-19 01:10 vstwin.c -rw-r--r-- 1 supertux supertux 8456 2005-11-20 16:35 vstwin.o / There is no libfst at the fst-1.7 build directory. Anybody did it with succes? Another question is, I see that there is another SC* file at fst-1.7/ardour/gtk_ardour/SConscript ,must it be copied too to the gtk_ardour directory found at the building directory of ardour-0.99? Thanks very much in advance. Saludos Cheers -- Carlos.
