I'm trying to get bjam and clang to play nice. I have Ubuntu linux running in an VM with boost trunk and the llvm+clang sources also from svn. I've built clang as described here: <http://clang.llvm.org/get_started.html>. I added the following line to my user-config.jam: using clang : : /home/eric/build/Debug+Asserts/bin/clang++ ; Now when I try to build, say, the Foreach tests, I get: In file included from cstr_byref.cpp:11: In file included from ../../../boost/test/minimal.hpp:37: In file included from ../../../boost/test/impl/execution_monitor.ipp:170: In file included from /usr/include/errno.h:36: In file included from /usr/include/bits/errno.h:25: /usr/include/linux/errno.h:4:10: fatal error: 'asm/errno.h' file not found #include <asm/errno.h> ^ 1 error generated. "/home/eric/build/Debug+Asserts/bin/clang++" -c -x c++ -O0 -g -fno-inline -Wall -g -fPIC -DBOOST_ALL_NO_LIB=1 -I"../../.." -o "../../../bin.v2/libs/foreach/test/cstr_byref.test/clang-linux-3.0/debug/cstr_byref.o" "cstr_byref.cpp" What have I done wrong? -- Eric Niebler BoostPro Computing http://www.boostpro.com
