[cfe-dev] 'make install' fails to find libclang_rt.cc_kext.a...?

[Sean McBride via cfe-dev]

Hi again,

So I tried a trivial installation based on the website 'get started' page.  I did exactly this:

mkdir ~/llvm-test
cd ~/llvm-test
svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
cd llvm/tools
svn co http://llvm.org/svn/llvm-project/cfe/trunk clang
cd ../..
cd llvm/projects
svn co http://llvm.org/svn/llvm-project/compiler-rt/trunk compiler-rt
cd ../..
mkdir build
mkdir install
cd build
cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=~/llvm-test/install ../llvm
make -j16 install

and again get:

  file INSTALL cannot find
  "/Users/sean/llvm-test/build/./lib/clang/3.8.0/lib/darwin/libclang_rt.cc_kext.a".

I repro this on two different Macs, one 10.10 and one 10.11.  Am I really the only one seeing this?

Thanks,

Sean
