povray 3.7 fails with thread-local storage not supported

[peyser.alex@…]

Povray was updated in a recent ticket because of libpng. But I can't find a version of gcc on osx lion that actually compiles it --- and as far as I can tell, it may require some version of clang (??? possibly ???).

Please try a clean build and attach the log if it fails:

$ sudo port clean povray
$ sudo port selfupdate
$ sudo port -d install povray

In the future please remember to use WikiFormatting and fill in the port field.

Tried with mp-gcc47, mp-gcc46, llvm-gcc42 (I think, since I set port select gcc before port install)

The log you attached shows that you are on OS X 10.6 Snow Leopard, not Lion.

The povray port does not specify a compiler, so it uses the default compiler MacPorts specifies. You appear to have Xcode 3.x, because MacPorts has chosen to use GCC 4.2 to compile this port.

You should report this problem to the developers of povray; they need to fix it to be compatible with GCC on OS X. You could point them to ​this page which seems to explain the problem. It compiled fine for me on Mountain Lion with Xcode 4.4 and clang, so presumably clang does now have an implementation of thread-local storage (and that page does not mention that).

Most ports including povray deliberately do not use what you set with "port select gcc". If you want to specify a different compiler, you would do it like this:

sudo port clean povray
sudo port install povray configure.compiler=clang

or:

sudo port clean povray
sudo port install povray configure.compiler=llvm-gcc42

From the mailing lists, they've known about it for several years and have decided that that's not going to happen (fixing it to work on old gcc's). So apparently the resolution is that this port will only work with Xcode > 4, unless anyone happens to know a variety of gcc or clang from earlier versions where thread local variables have crept in. Clang-3.1 from macports fails here as well, using configure.compiler and configure.cxx.

Ok. Then you could install the clang-3.2 port and compile with:

sudo port clean povray
sudo port install povray configure.compiler=macports-clang-3.2

If that works, we can modify the port accordingly.

I'll try when Ticket #36042 is resolved....
