[linux-audio-dev] C++ guru needed (again)

Greetings: The following message is produced by Debian's GCC4 in 64Studio when compiling Csound5 for AMD64: g++ -o frontends/fltk_gui/CsoundGlobalSettings.o -c -fexceptions -Wall -g -gstabs -O2 -fPIC -DLINUX -DPIPES -DHAVE_LIBSNDFILE=1016 -DHAVE_FLTK -DBETA -DHAVE_FCNTL_H -DHAVE_UNISTD_H -DHAVE_STDINT_H -DHAVE_SYS_TIME_H -DHAVE_SYS_TYPES_H -DHAVE_TERMIOS_H -DHAVE_SOCKETS -DHAVE_DIRENT_H -I. -IH -I/usr/local/include -I/usr/include -I/usr/X11R6/include -Iinterfaces -I/usr/include/freetype2 frontends/fltk_gui/CsoundGlobalSettings.cpp frontends/fltk_gui/CsoundGlobalSettings.cpp: In constructor 'CsoundGlobalSettings::CsoundGlobalSettings()': frontends/fltk_gui/CsoundGlobalSettings.cpp:47: internal compiler error: output_operand: invalid expression as operand Please submit a full bug report, with preprocessed source if appropriate.

John ffitch has successfully compiled Cs5 for AMD64 with FLTK support, but he used GCC3. I've tried the various options for scons, but got no joy whenever I used Word64=1, the build always dies at the same point. Yes, I do see the compiler report request, but when I searched Google I found documents stating that this particular error was supposed to be resolved already by GCC4. Does anyone see what needs to be done to get past this point with the FLTK stuff in Cs5 ? Any suggestions for a fix ? I'll gladly furnish any other imformation required, just let me know what's needed. Best, dp
