Because Squid does not use __sync_fetch_and_add_8. It uses __sync_fetch_and_add() The OS is itelf defining __sync_fetch_and_add() in terms of __sync_fetch_and_add_8 but then not providing the operator it depends on. > > The issue, I believe, is libc++ hasnt been ported to openbsd so it uses > libstdc++ > > the compiler in question: > [apalmer]:/data/src/squid-3.5.2# g++ -v > Reading specs from /usr/lib/gcc-lib/i386-unknown-openbsd5.6/4.2.1/specs > Target: i386-unknown-openbsd5.6 > Configured with: OpenBSD/i386 system compiler > Thread model: posix > gcc version 4.2.1 20070719 > > soooooo, manually editing autoconf.h to: > #define HAVE_ATOMIC_OPS 0 > > Is there a more graceful way to deal with this? Perhapse building with Clang instead of the old GCC. The recent BSD operating systems have all given up on GCC due to GPLv3 compatibility issues.
