AFLGO_TRACING error about aflgo HOT 3 CLOSED

I changed the createglobalstrptr to GlobalVariable, but a new error comes as follows. I'm using llvm 7.0. I want to know what version of llvm you used.

-- Building tiff version 4.0.7

CMake Error at /usr/share/cmake-3.5/Modules/CMakeTestCCompiler.cmake:61 (message):
The C compiler "/home/lt/aflgo-org/afl-clang-fast" is not able to compile a

It fails with the following output:

hi @levi-2018
Look at your error message, I see that you are using LLVM 7.0. Can you please try to use LLVM 3.8 or LLVM 4.0?

There could be some LLVM-version specific issue that we have not encountered. We tested our tool mostly with LLVM 3.8 and LLVM 4.0.

Ok, I'll try it with LLVM 4.0. Thank you.
