Compilation error building sfepy
Hi -
I'm trying to build SfePy on a CentOS-5 x86_64 machine. I'm using Python 2.7 which has the mandatory dependencies stated in the INSTALL file. I don't yet have all the optional dependencies but thought I would try to just get started with the simplest build strategy. The compiler is gcc 4.1.2. A full log of the output from "python setup.py build_ext --inplace" is in the following paste:
http://paste.pocoo.org/show/536250/
The error is:
... compiling C sources C compiler: gcc -pthread -fno-strict-aliasing -fPIC -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC
compile options: '-D__SDIR__='"sfepy/fem/extmods"' -DSFEPY_PLATFORM=0 -D__SDIR__='"sfepy/fem/extmods"' -DSFEPY_PLATFORM=0 -Isfepy/fem/extmods -I/proj/sot/ska/dev/arch/x86_64-linux_CentOS-5/lib/python2.7/site-packages/numpy/core/include -I/proj/sot/ska/dev/arch/x86_64-linux_CentOS-5/include/python2.7 -c' extra options: '-g -O2' gcc: sfepy/fem/extmods/mappings.c sfepy/fem/extmods/mappings.c: In function \u2018__pyx_pf_5sfepy_3fem_7extmods_8mappings_14CVolumeMapping___cinit__\u2019: sfepy/fem/extmods/mappings.c:1116: error: incompatible types in assignment sfepy/fem/extmods/mappings.c:1190: error: incompatible types in assignment sfepy/fem/extmods/mappings.c:1264: error: incompatible types in assignment sfepy/fem/extmods/mappings.c: In function \u2018__pyx_pf_5sfepy_3fem_7extmods_8mappings_15CSurfaceMapping___cinit__\u2019: ... <AND MORE LIKE THIS>
Any ideas on the source of this problem? I thought about trying to build on a more modern OS, but eventually I'll need to run this on CentOS-5.
Thanks, Tom
Hi tom, get the EPD from enthought, its free for academic use. http://download.enthought.com/epd_7.2/ download the Linux package and install. then try to build sfepy again. (either epd-7.2-2-rh5-x86.sh or epd-7.2-2-rh5-x86_64.sh depending on your architecture)

Great, that did the trick. My normal Python distribution is actually ActivePython underneath, so it's interesting that there is some build issue.
BTW, "make clean" and even "rm -rf build" were apparently insufficient to really clean the build. This doesn't quite make sense, but I'll say that after these steps I tried building with EPD and it failed with exactly the same error. So out of desperation I started fresh from the source tarball and *then* it worked with EPD.
Anyway, now hopefully I can start learning SfePy.
Thanks, Tom

Glad to hear you managed to build it. As for the original error, it occurred in a cython-generated C code, so it might have been some cython-gcc version incompatibility.
"make clean" is an alias to "python setup.py clean" but there is a "stronger" command, namely "python setup.py clean --all", which should really clean everything.
Anyway, now hopefully I can start learning SfePy.
Great, do not hesitate to ask here in case of problems!
Cheers, r.
