llvm dev - Sep 2015 - Problems building LLVMHello, spaces in path

I recently had a problem creating LLVMHello.

I used this CMake file

#!/bin/sh
# clangcmake.sh
cmake -G "Eclipse CDT4 - Unix Makefiles"
-DLLVM_TARGETS_TO_BUILD="X86"
-DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DCMAKE_BUILD_TYPE="Debug"
-DCMAKE_ECLIPSE_VERSION=4.5 -DCMAKE_CXX_COMPILER=clang++
-DCMAKE_C_COMPILER=clang ../llvm



then I ran

make LLVMHello

and the build failed on an error about LLVMHello.export


The problem turned out to be that the parent directory path had a
space in one of the folder names.

I removed the space and now LLVMHello builds properly.

Hope you find this useful.

Spaces in paths are generally just a pain, but without the actual error message
there is little we can do to fix the error.

If you reproduce the issue again, please file a bug on https://llvm.org/bugs/
<https://llvm.org/bugs/>, and include the error message.

Thanks,
