C++17 support #32

Closed v1993 closed 5 years ago

v1993 commented 5 years ago

I try to build C++17 project with cmake using zapcc but get this:

cmake -DCMAKE_CXX_COMPILER=zapcc++ ..
-- The CXX compiler identification is Clang 5.0.0
-- Check for working CXX compiler: /usr/bin/zapcc++
-- Check for working CXX compiler: /usr/bin/zapcc++ -- broken
CMake Error at /usr/share/cmake-3.12/Modules/CMakeTestCXXCompiler.cmake:45 (message):
  The C++ compiler

    "/usr/bin/zapcc++"

  is not able to compile a simple test program.

  It fails with the following output:

Is there any chance that C++17 will be supported?

P.S.: happy NY!

Hi, not sure when I'll have time to update zapcc for -std=gnu++17, sorry.
