Reproducible: Always Steps to Reproduce: 1. compile any source using cppvmBarrier::barrier() while including e.g. csignal or signal.h #include <cppvm.h> #include <csignal> int main() { cppvmBarrier tSyncPoint(); tSyncPoint.barrier(); } Actual Results: error: `__memory_barrier' undeclared the macro barrier() substitutes the method barrier() by __memory_barrier (see /usr/include/linux/compiler.h of linux26-headers) Expected Results: the macros should not interfere with external sources This bug is related to bug #56885. While the latter is solved and cdrdao-1.1.8 compiles fine on my system, the macros defined in linux26-headers still interfere with other sources. dberkholz@gentoo.org 2005-02-21 01:10:41 0000 Is this still a problem? If so, do you have a suggested fix for it? tyger@gmx.de 2005-02-21 03:58:29 0000 Actually, there is a new bug introduced by http://bugs.gentoo.org/show_bug.cgi?id=82614 . The standard PVM_ARCH=LINUX was changed to PVM_ARCH=LINUXI386 by the s390-Patch. The bugfix corrects this by creating appropriate config files for this ARCH, but cppvm still relies on PVM_ARCH=LINUX. After installing cppvm by manually symlinking LINUXI386 with LINUX at a few spots, I was able to test the original bug. The bug still exists, but with a different error message: cppvm.c:6: error: expected unqualified-id before "asm" cppvm.c:6: error: expected `;' before "asm" I'm using linux26-headers-2.6.8.1-r2 Workaround: Don't use csignal/signal.h in your cppvm-Programs! Possible fix: don't include compiler*.h in dependency tree of signal.h. Maybe this is an upstream 'feature' in kernel sources. Cya, Ed dberkholz@gentoo.org 2005-02-21 16:24:52 0000 I'm working on an update to pvm 3.4.5, hopefully that'll resolve a couple of issues. dberkholz@gentoo.org 2005-02-21 22:52:08 0000 OK, check out 3.4.5 plasmaroo@gentoo.org 2005-03-13 08:53:58 0000 Please try 3.4.5.
