Tested using some simple 1-bit adder code I had. Please add ~amd64 keyword.
I ran the test from http://dev.gentoo.org/~calchan/sci-electronics/tests/#doc_chap6 and got g++ -Wall -DSC_USE_PTHREADS -DSC_INCLUDE_FX -O3 -o fft fft.o main.o sink.o source.o -L/tmp/systemc-2.2.05jun06_beta/lib-linux64 -lsystemc -lm /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../lib64/libsystemc.a(sc_cor_pthread.o): In function `sc_core::sc_cor_pkg_pthread::create(unsigned long, void (*)(void*), void*)': : undefined reference to `pthread_create' /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../lib64/libsystemc.a(sc_cor_pthread.o): In function `sc_core::sc_cor_pkg_pthread::create(unsigned long, void (*)(void*), void*)': : undefined reference to `pthread_attr_setstacksize' collect2: ld returned 1 exit status make[4]: *** [fft] Error 1 make[4]: Leaving directory `/tmp/systemc-2.2.05jun06_beta/examples/sysc/fft/fft_flpt' make[3]: *** [check-am] Error 2 make[3]: Leaving directory `/tmp/systemc-2.2.05jun06_beta/examples/sysc/fft/fft_flpt' make[2]: *** [check-recursive] Error 1 make[2]: Leaving directory `/tmp/systemc-2.2.05jun06_beta/examples/sysc/fft' make[1]: *** [check-recursive] Error 1 make[1]: Leaving directory `/tmp/systemc-2.2.05jun06_beta/examples/sysc' make: *** [check-recursive] Error 1

Unfortunately I won't be able to use it for more than this, so could you please have a look at it and try to isolate the source of the problem ? It looks to me like maybe some gthread/pthread conflict. That -DSC_USE_PTHREADS option to g++ certainly looks like a good lead to start investigating. Maybe the option needs to be removed, or the order of '-lsystemc -lm' needs to be inverted, or something. If you can't find out what it is, could you please check with somebody else in the amd64 team ? Thanks in advance, Denis.

Removing -DSC_USE_PTHREADS and inverting the order, gives me: g++ -Wall -DSC_INCLUDE_FX -O3 -o fft fft.o main.o sink.o source.o -L/tmp/systemc-2.2.05jun06_beta/lib-linux64 -lm -lsystemc /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -lsystemc collect2: ld returned 1 exit status
Ok the problem here is with the Makefile.in and Makefile.am files not including -lpthread. A quick fix; cd examples find . -type f -name 'Makefile.*' -print | while read filename do ( sed 's/\-lm/\-lm\ \-lpthread/i;' $filename > $filename.xxxx mv $filename.xxxx $filename ) done Regenerate the makefiles by re-running the ./configure script and it should all compile fine.

Are you sure you didn't unmerge it ? Denis.

OMFG....if we should ever meet in person you are allowed to kick my butt, for not properly reading error messages I post on bugs. It works! I keyworded it ~amd64 and maybe you could check if this is fixed upstream.
Thanks to both of you. I reopen this bug as a tracker to include the fix in the postinstall message and my test bench. Denis.
