Hi, I'm getting the following errors, when attempting to build llvm-3.1 (from f18) on my Fedora 17 setup. In file included from APInt.cpp:16: In file included from /home/ilyes/fedora-scm/llvm/llvm-3.1.src/include/llvm/ADT/APInt.h:18: In file included from /home/ilyes/fedora-scm/llvm/llvm-3.1.src/include/llvm/ADT/ArrayRef.h:13: In file included from /home/ilyes/fedora-scm/llvm/llvm-3.1.src/include/llvm/ADT/SmallVector.h:23: In file included from /usr/bin/../lib/gcc/x86_64-redhat-linux/4.7.0/../../../../include/c++/4.7.0/iterator:63: In file included from /usr/bin/../lib/gcc/x86_64-redhat-linux/4.7.0/../../../../include/c++/4.7.0/ostream:39: In file included from /usr/bin/../lib/gcc/x86_64-redhat-linux/4.7.0/../../../../include/c++/4.7.0/ios:42: In file included from /usr/bin/../lib/gcc/x86_64-redhat-linux/4.7.0/../../../../include/c++/4.7.0/bits/ios_base.h:40: /usr/bin/../lib/gcc/x86_64-redhat-linux/4.7.0/../../../../include/c++/4.7.0/ext/atomicity.h:48:45: error: use of undeclared identifier '__ATOMIC_ACQ_REL' { return __atomic_fetch_add(__mem, __val, __ATOMIC_ACQ_REL); } ^ /usr/bin/../lib/gcc/x86_64-redhat-linux/4.7.0/../../../../include/c++/4.7.0/ext/atomicity.h:52:38: error: use of undeclared identifier '__ATOMIC_ACQ_REL' { __atomic_fetch_add(__mem, __val, __ATOMIC_ACQ_REL); } I've got also a bunch of these: /usr/bin/../lib/gcc/x86_64-redhat-linux/4.7.0/../../../../include/c++/4.7.0/limits:1404:27: error: use of undeclared identifier '__int128'; did you mean '__int128_t'? and this is with gcc version 4.7.0 20120507 (Red Hat 4.7.0-5) (GCC). Any ideas on how to fix this? Do I need an updated GCC? Regards, -Ilyes -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
