I do not know if this is a gcc 3.0.3 problem only, but when compiling Electric Fence, it gives the following error: cc -g -DUSE_SEMAPHORE -fPIC -c print.c -o print.o print.c: In function `EF_Printv': print.c:114: `char' is promoted to `int' when passed through `...' print.c:114: (so you should pass `int' not `char' to `va_arg') make: *** [print.o] Error 1 The following patch fixes the problem: ----------------------------------------------------------------------- diff -u -r ElectricFence-2.2.2.orig/print.c ElectricFence-2.2.2/print.c --- ElectricFence-2.2.2.orig/print.c Sun Apr 11 18:29:21 1999 +++ ElectricFence-2.2.2/print.c Wed Jan 16 00:24:38 2002 @@ -111,7 +111,7 @@ break; case 'c': { - char c = va_arg(args, char); + char c = va_arg(args, int); (void) write(2, &c, 1); } ------------------------------------------------------------------------ I placed this patch in /usr/portage/dev-util/efence/files/efence-2.2.2.patch Then edited efence-2.2.2.ebuild to include: src_compile() { patch -p1 < ${FILESDIR}/${P}.patch # This is the included line emake || die }
This doesn't happen with gcc 2.95.3. Since gcc 3.0.3 is not considered as the stable gentoo compiler I'd like to leave it like this. Maybe by the time gcc 3 is considered supported, a new version of efence will get out that fixes this.
