[llvm-dev] darwin bootstrap failure

Hi Jack:

The only way I could reproduce the problem you are seeing was to rerun
cmake with -DCMAKE_BUILD_TYPE=Debug in a build directory previously
configured with -DCMAKE_BUILD_TYPE=Release.  I can fix that, but not sure
if it's what you are seeing.

If this isn't your case, could you send me the actual commands you ran?

In the meantime, you can add -DLLVM_FOURCE_ENABLE_DUMP=ON to your cmake
invocation which should guarantee LLVM_ENABLE_DUMP is defined.

hth...
