Tried it with the sandbox-exec version of the commands, same issue. Googled around a bit and found a similar report about compiling MySQL here
The followup there about using cmake .. -DCMAKE_CXX_COMPILER=g++ -DCMAKE_CC_COMPILER=gcc instead (and I do have gcc and g++ installed) did not work. I tried just make again after doing that, got the same seemingly bogus error that The C compiler "/Developer/usr/bin/cc" is not able to compile a simple test program. Dunno if one must do something different with make after doing these special things with cmake. When I manually try to run the simple test compile, with /opt/local/bin/gmake "cmTC_e9be6/fast", I'm told: gmake: *** No rule to make target 'cmTC_e9be6/fast'. Stop.

So, at this point I can't get the deps to compile much less the game app. I generally do not have compile problems like this, and regularly use MacPorts, Homebrew, and even occasionally Fink to install what I want (whichever has the most current version of something). Admittedly, I generally do not compile stuff from scratch off GitHub, but only using those managers.

Thanks for your report. It looks like you're using GCC, but, unfortunately, I never tested this repo with compilers except for Xcode's built-in Clang.

[nikolaykasyanov]

GCC support is discussed in #49.

[Darklocq]

Thanks for the followup. This will probably seem like a dumb question, but if I wanted to try the "Xcode's built-in Clang" method, how would I go about that? Is it simply a matter of using a different path for cmake and make? The only compiling I do is for MacPorts and Homebrew these days, so I don't know a thing about Xcode.

[nikolaykasyanov]

@Darklocq nothing dumb about it!

Both CMake and Make should be compiler-agnostic, actually. I'm not entirely sure about the mechanism CMake uses to find compilers, although I'd suggest that it simply tries whatever is in CC and CXX environment variables first. It's possible to pass desired compilers to CMake explicitly though:

$ cmake -DCMAKE_C_COMPILER=$(xcrun --find clang) -DCMAKE_CXX_COMPILER=$(xcrun --find clang++) ....

Please make sure xcrun knows where to find the tools by doing the following after installing Xcode:

$ sudo xcode-select --switch /Application/Xcode.app # or whatever your Xcode path is

Actually, having Xcode command line tools could be enough (and since you use Homebrew, I assume you have them installed), unfortunately I can't verify it because I have Xcode everywhere due to being an iOS app developer.

[Darklocq]

Thanks for the hand-holding. I will give this a try (though almost a year down the road, I don't exactly recall why I was so hot to compile my own copy; I'm sure it'll come back to me eventually).

[nikolaykasyanov]

FYI I've edited the xcode-select command.
