Build / Compile error

Cling
1

G’day,

I am attempting to build cling under OSX and am getting the compilation error below.
Is it safe to make the edit to get the code to compile?

Help appreciated.

Hi Philip,

You are likely to have a mismatch between the version of LLVM and the version of cling. See the file cling/interpreter/cling/LastKnownGoodLLVMSVNRevision.txt to know which revision of LLVM to use.

Cheers,
Philippe.

OK -
Downloaded the latest known good version of llvm / clang and
the build process now works - and I am now away.

Thanks very much.
