I'm getting the same type of error:<br>
<br>
COMPILE: clang_linux/asan-i386/i386: /home/stephen/Workspace/clang-standalone-workspace/build/project/clang-standalone/bootstrap/src/llvm/projects/compiler-rt/lib/asan/asan_malloc_mac.cc<br>
/home/stephen/Workspace/clang-standalone-workspace/build/project/clang-standalone/bootstrap/src/llvm/projects/compiler-rt/lib/asan/asan_linux.cc:24:10: fatal error:<br>
'sys/time.h' file not found<br>
#include <sys/time.h><br>
<br>
which seems confusing as I configured my LLVM build with ./configure --enable-targets=x86_64 (I also tried this with --enable-targets=host on a Ubuntu 12.04 64 bit system) which should not have included the i386 support and thus not need the multiarch support...<br>
<br>
Any suggestion on how to constrain the compiler-rt build to x86_64 target only?<br>
<br>
Thanks!<br>
