Detailled description

OgreMain builds without errors but anything trying to link to it has errors like this:

The linker errors always seem to involve std::__1::basic_string<char, std::__1::char_traits so it looks to me like a libc++ compatibility issue, however the compile commands all have -stdlib=libc++ .

duplicate of #894. Its trying to link x86_64 against i386

Its trying to link x86_64 against i386

I've set CMAKE_OSX_ARCHITECTURES to x86_64 and the ld commands all have -arch x86_64. I don't see any evidence of that.

[paroj]

it is imperative which -arch is specified during compilation. Did you pass CMAKE_OSX_ARCHITECTURES before configure? You must invoke cmake via command line instead of using the gui for this. If not, try again with a clean build folder.

Meanwhile I am tracking a 10.14 build here: #1145

[paroj]

also try enabling GL3+ enabled (yeah the build scripts are arcane)

[glennra]

It builds using the makefile generator. The issue must be with Xcode.
