OS X Compiling errors with qt5 from homebrew

[safetypins]

So, I originally had an issue running the qmake command, but after the inclusion of the icns file, that error has been resolved, and it is now replaced by:

make: *** [main.o] Error 1

So, as I said in the title, I installed qmake via homebrew instead of the recommended way of compiling it myself. Can you tell from this error message if that is the problem?

[paul]

I got the same error, I had to re-install qt5 from homebrew with the -static flag set, and then it got a little further, now its complaining about:

glmap.cpp:454:33: error: use of undeclared identifier 'floor'
  scale = qMin(width, height) / floor(zoom);

[mojotx]

The way to fix the glmap.cpp issue is to add an include for cmath. I also had to make some tweaks to the TerraFirma.pro file to get it to compile under El Capitan.

I have the application so that it compiles and runs, but it's not working. I get a grey screen with no graphics whatsoever. Feel free to see my forked repository, and look in the "mjarvis-osx-fixes" branch.

Here's my full diff of what I've changed so far. Note that you will need to install to /usr/local instead of /usr, because of System Integrity Protection in OS X El Capitan. That's generally a best practice for Linux as well, IMHO. I also had to tell qmake to add the c++11 flag.

All changes have been merged.. and I went ahead and made a binary for El Capitan, it's on the website.
