I have fixed the "#ident" problem by patching /usr/src/contrib/gcc/c-ppoutput.c to remove the double quotes, see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16999 --- src/contrib/gcc/c-ppoutput.c 2004/08/26 14:10:04 1.1 +++ src/contrib/gcc/c-ppoutput.c 2004/08/26 14:10:32 @@ -292,7 +292,7 @@ const cpp_string *str) { maybe_print_line (print.map, line); - fprintf (print.outf, "#ident \"%s\"\n", str->text); + fprintf (print.outf, "#ident %s\n", str->text); print.line++; } and installed that cc et al in /usr/bin. I can make it work for buildkernel (cuts down time to 30%, woohoo!), but $ make -s CC='/usr/local/bin/ccache cc' CXX='/usr/local/bin/ccache c++' buildworld and $ make -s CC='/usr/local/bin/ccache /usr/bin/cc' CXX='/usr/local/bin/ccache /usr/bin/c++' buildworld both fail with [...] ===> lib/libpam/modules/pam_unix (all) ===> lib/libpam/libpam (all) ===> lib/libautofs (all) /share/HEAD/src/lib/libautofs/libautofs.c:49:30: fs/autofs/autofs.h: No such file or directory /share/HEAD/src/lib/libautofs/libautofs.c: In function `autoreq_get': /share/HEAD/src/lib/libautofs/libautofs.c:253: error: invalid use of undefined type `struct autofs_userreq' /share/HEAD/src/lib/libautofs/libautofs.c:253: error: dereferencing pointer to incomplete type /share/HEAD/src/lib/libautofs/libautofs.c: In function `do_autoreq_get': [...] while without ccache the buildworld completes successfully as expected. So it's not an issue with my src tree and it's not an issue of leftovers from previous builds as I always start from scratch with cvs co src in an empty directory. I rather expect some subtle interaction of ccache and the CC environment/make variables with the build. A possible candidate is /usr/bin/mkdep which is used a lot during builds and is sensitive to CC settings. Anyone successfully used ccache for a buildworld?
