:) no, adding -lffi to the test doesn't work: /usr/lib/gcc/powerpc-unknown-linux-gnu/3.4.4/../../../../powerpc-unknown-linux-gnu/bin/ld: cannot find -lffi collect2: ld returned 1 exit status And now that the scons has been fixed up, it gives me, as expected, Checking for ffi_call() in C library ffi... no YHC requires LibFFI to be installed and working. In case the information helps: the version of libffi (it seemed like) I installed was 3.4.3, corresponding to the GCC release of that version number (indeed, using its source code). (Although it's very probably irrelevant, I'm using GCC 3.4.4 as my C compiler.) Now looking around, I found /usr/lib/libffi -- it's a directory! $ ls -lR /usr/lib/libffi/ /usr/lib/libffi/: total 48 -rw-r--r-- 1 root root 19970 Jul 5 17:31 libffi.a -rwxr-xr-x 1 root root 722 Jul 5 17:31 libffi.la lrwxrwxrwx 1 root root 15 Jul 5 17:31 libffi.so -> libffi.so.3.0.0 lrwxrwxrwx 1 root root 15 Jul 5 17:31 libffi.so.3 ->libffi.so.3.0.0 -rwxr-xr-x 1 root root 18640 Jul 5 17:31 libffi.so.3.0.0 drwxr-xr-x 2 root root 4096 Jul 5 17:31 nof /usr/lib/libffi/nof: total 52 -rw-r--r-- 1 root root 21386 Jul 5 17:31 libffi.a -rwxr-xr-x 1 root root 726 Jul 5 17:31 libffi.la lrwxrwxrwx 1 root root 15 Jul 5 17:31 libffi.so -> libffi.so.3.0.0 lrwxrwxrwx 1 root root 15 Jul 5 17:31 libffi.so.3 ->libffi.so.3.0.0 -rwxr-xr-x 1 root root 21104 Jul 5 17:31 libffi.so.3.0.0 [a couple spaces deleted to keep the lines from wrapping] I don't know how much of this setup is Gentoo-specific, though, and I don't know how libffi would generically be installed (e.g. starting from the source tarball) in general.

Yes, I can compile that program "test.c" with gcc -c test.c Just to test, without darcs-pulling anything, I re-ran scons on yhc, and it worked to a greater extent than before (then erroring with: /usr/lib/gcc/powerpc-unknown-linux-gnu/3.4.4/../../../../powerpc-unknown-linux-gnu/bin/ld:
cannot find -lffi ) There must have been something temporary affecting that (my computer was rebooted in between).
does gcc test.c -lffi work? :-)
After darcs pull, scons errored:
<snip scons error>
sorry my fault, forgot to add a file to the repo when I made a change.
thanks :-)
