[osg-users] Building on macOS 10.14

[Jan Brejcha]

Hi, the problem is that CMake is not able to find valid compiler due to the fact that it tries to use stdlibc++. I have latest version of XCode 10.1 and command line tools.

The exact error is this one:

Code:

CMake Error at /Applications/CMake.app/Contents/share/cmake-3.13/Modules/CMakeTestCXXCompiler.cmake:45 (message):
  The C++ compiler

    "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++"

  is not able to compile a simple test program.

  It fails with the following output:

It is also weird that before the update to macos 10.14 I have had exactly the same version of XCode as I have now, and everything worked well for me. I didn't do much research about it, but it looks like it could be a change in the system environment or CMake maybe?
