Hi, I recently tried to get chuck working on my new UbuntuStudio 64bit install and I can't get it to work properly. When I "make linux-jack" it seems to go okay and the last couple lines are as follows: g++ -D__LINUX_JACK__ -c -O3 -D__CK_SNDFILE_NATIVE__ uana_xform.cpp g++ -D__LINUX_JACK__ -c -O3 -D__CK_SNDFILE_NATIVE__ uana_extract.cpp g++ -o chuck chuck.tab.o chuck.yy.o chuck_absyn.o chuck_parse.o chuck_errmsg.o chuck_frame.o chuck_symbol.o chuck_table.o chuck_utils.o chuck_vm.o chuck_instr.o chuck_scan.o chuck_type.o chuck_emit.o chuck_compile.o chuck_dl.o chuck_oo.o chuck_lang.o chuck_ugen.o chuck_main.o chuck_otf.o chuck_stats.o chuck_bbq.o chuck_shell.o chuck_console.o chuck_globals.o digiio_rtaudio.o hidio_sdl.o midiio_rtmidi.o rtaudio.o rtmidi.o ugen_osc.o ugen_filter.o ugen_stk.o ugen_xxx.o ulib_machine.o ulib_math.o ulib_std.o ulib_opsc.o util_buffers.o util_console.o util_string.o util_thread.o util_opsc.o util_math.o util_network.o util_raw.o util_xforms.o util_hid.o uana_xform.o uana_extract.o -lasound -ljack -lstdc++ -ldl -lm -lsndfile make[1]: Leaving directory then when I run "chuck moe.ck" I get: JACK tmpdir identified as [/dev/shm] Enhanced3DNow! detected SSE2 detected JACK tmpdir identified as [/dev/shm] Enhanced3DNow! detected SSE2 detected JACK tmpdir identified as [/dev/shm] Enhanced3DNow! detected SSE2 detected Segmentation fault (core dumped) Where is my problem lying? I'm of the linux age where I shouldn't have to understand how to compile from code to get things to run and the Chuck install instructions say nothing about which programs and libraries (other than libsndfile) are required etc.. to make. That info would be a very good addition on the next release.
