Error in IECoreMaya.cpp #48

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.build all required libraries as best as possible on Fedora Core 16 and 
install them to separate directories under /opt so that they don't destroy 
Fedora which uses newer versions of those libraries (which some of the code is 
incompatible with, but I can't say which because I had to reinstall Fedora 
several times afterwords and lost all that data...)
2.tweak sconstruct and write a bash script to setup environment
3. run bash script in terminal to build Cortex

What is the expected output? What do you see instead?
IECoreMaya.so should be built, but build fails at:
"BOOST_STATIC_ASSERT(sizeof(Py_UNICODE) == 4);"

"src/IECoreMaya/bindings/IECoreMaya.cpp:104:1: error: invalid application of

The problem is that Python can be compiled in a couple of ways, affecting how 
Unicode strings are handled in Python. Cortex will happily deal with either 
way, but Maya uses a Python with Py_UNICODE==4. For that reason we put a check 
in the code that ensures that when you're building IECoreMaya, you're building 
against a suitable Python (one that matches Maya). You can either a) Point the 
Sconstruct inside the Maya installation to find python, or build python 
yourself passing "--enable-unicode=ucs4" to the configure command.
