Hello Aleksander and Peter, Thanks for your replies. >>> Updated ports (it's been quite a while) and attempting to rebuild x11 >>> fails for llvm37 claiming the compiler needs libatomic and it's not >>> there. What's the deal with libatomic? > > You will need to install lang/clang-devel to successfully update llvm37. When I try to install clang-devel I get the same error: -- Performing Test HAVE_CXX_ATOMICS_WITHOUT_LIB -- Performing Test HAVE_CXX_ATOMICS_WITHOUT_LIB - Failed -- Looking for __atomic_fetch_add_4 in atomic -- Looking for __atomic_fetch_add_4 in atomic - not found CMake Error at cmake/modules/CheckAtomic.cmake:36 (message): Host compiler appears to require libatomic, but cannot find it. Call Stack (most recent call first): cmake/config-ix.cmake:296 (include) CMakeLists.txt:412 (include) > If you still have a problem with libatomic could you please provide > more information - OS version, make.conf, port flags, more logs, etc? The CMakeError.log file indicates a number of errors: Run Build Command:"/usr/local/bin/ninja" "cmTC_32962" [1/2] Building C object CMakeFiles/cmTC_32962.dir/CheckIncludeFile.c.o FAILED: /usr/local/bin/gcc48 -O2 -pipe -isystem /usr/local/include -fstack-protector -Wl,-rpath=/usr/local/lib/gcc48 -fno-strict- aliasing -o CMakeFiles/cmTC_32962.dir/CheckIncludeFile.c.o -c CheckIncludeFile.c In file included from CheckIncludeFile.c:1:0: /usr/include/malloc.h:3:2: error: #error "<malloc.h> has been replaced by <stdlib.h>" #error "<malloc.h> has been replaced by <stdlib.h>" ^ ninja: build stopped: subcommand failed. and others, ending with: /usr/local/bin/ld: cannot find -lcxxrt collect2: error: ld returned 1 exit status I'm guessing this is a configuration error on my system, probably related to 10.x changes; I'm running 9.2-RELEASE-p12 /etc/make.conf contains: PERL_VERSION=5.20.3_9 DEFAULT_VERSIONS+=perl5=5.20.3_9 WITH_PKGNG=yes WITH_BDB_VER=5 OPTIONS_SET=X11 OPTIONS_UNSET=NLS WITH_OPENSSL_PORT=yes When I first saw the error I installed devel/libatomic_ops, but that creates /usr/local/lib/libatomic_ops.a and libatomic_ops_gpl.a. Not libatomic.* There is also a libboost_atomic.* set from about 6 months ago. However, given the other errors above from ninja I'm guessing this is more than just a libatomic problem. Thanks for any additional clues, Gary
