Alien::wxWidgets install fails on OSX 10

Question

It's basically the same as this one which didn't really ended up.

I'm facing the same issue and I went a bit further. I had to change the code to allow a newer Macos sdk (10.11). So it compiled for a while but then failed whith this:

The weird thing is when I checked the config logs: This one (./wxWidgets-3.0.2/bld/src/tiff/config.log) has other errors than lzma, for instance:

See the full version.

Ans it's more or less the same with ./wxWidgets-3.0.2/bld/config.log.

When I changed the code to allow os10.10 SDK, it was previously expecting up to 10.8 or maybe 10.9. I suppose the whole issue comes now from this. Should I try to fetch an old MacOS SDK?

Basically, I just want to compile Slic3r --gui from source, which requires Wx, which requires wxwidgets.

Answer 1

The problem here is that libtiff configure detects lzma.h under /usr/local because it doesn't use -isysroot, but its compilation does, because of the SDK option, and fails to find it. The right thing to do would be to use -I/usr/local/include explicitly in wxWidgets configure, but for now you should be able to work around this by doing export CPATH=/usr/local/include LIBRARY_PATH=/usr/local/lib to bypass it.

Alternatively (and IMHO preferably), do brew install tiff jpeg png (not sure that the formulae names are correct, please check them) to avoid building the builtin versions of these libraries in the first place.
