System:
- macOS Sierra 10.12 public beta 3
- Xcode 8 beta 4:
Apple LLVM version 8.0.0 (clang-800.0.35)
Target: x86_64-apple-darwin16.0.0
Thread model: posix
InstalledDir:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
Description:
Downloaded the latest trunk (Update to HEAD: . at revision 277660)
And a "make -n" after a fairly standard "cmake
-DCMAKE_INSTALL_PREFIX=${INSTALL_PREFIX} -G "Unix Makefiles" ../llvm" errors
out like this...
/Applications/CMake.app/Contents/bin/cmake -E cmake_echo_color --switch=
--progress-dir=/Users/Me/Dev/build/CMakeFiles --progress-num=99 "Built target
obj.llvm-tblgen"
/Applications/Xcode.app/Contents/Developer/usr/bin/make -f

make: *** [all] Error 2
Looking at the file history for both cmake/modules/AddLLVM.cmake and
cmake/modules/TableGen.cmake, I found a dubious Fix Me and some past breakage.
See
<a href="https://smlnj-gitlab.cs.uchicago.edu/manticore/llvm/commit/68027c4618270e93bc8627e78a82557fca9a7bab">https://smlnj-gitlab.cs.uchicago.edu/manticore/llvm/commit/68027c4618270e93bc8627e78a82557fca9a7bab</a>
Is it safe to proceed (seems like not) disabling this feature? From a cursory
review looks like this flag is attempting to set up a shared object lib for two
targets LLVMTableGen and LLVMSupport. Will try doing without.
I've added the full output of my configure and build. Thanks in advance.</pre>
