#26 Compilation problem with clang++-10

[Anonymous]

opmock doesn't seem to compile with clang++-10:

For LLVM-10, part of the solution is to change this in opmock2.cpp:

#include "clang/ADT/ArrayRef.h"

...

clang::CompilerInvocation::CreateFromArgs (
        *CI, ArrayRef(Args.begin(), Args.end()), *DiagsRef );

but you must also include the abstract data type library:

opmock2.cpp:58:10: fatal error: 'clang/ADT/ArrayRef.h' file not found
#include "clang/ADT/ArrayRef.h"
         ^~~~~~~~~~~~~~~~~~~~~~
1 error generated.
<builtin>: recipe for target 'opmock2.o' failed
make: *** [opmock2.o] Error 1

and a simple -lclangADT didn't work.

Hi,

Thank you for reporting. I'll try to have a look this week to this bug and come back to you here.
