[Matplotlib-users] Issues with clang when building on MacOS 10.7

2012-02-23 Thread Thomas Robitaille
Hello,

I am trying to build the latest version of matplotlib from the git repository 
(1cd07a6c) on MacOS 10.7, and regardless of whether I build using the make.osx 
file or just 'python setup.py build', the C files get compiled with clang, and 
clang raises an error on one of the files:

/Developer/usr/bin/clang -fno-strict-aliasing -fno-common -dynamic -pipe -O2 
-fwrapv -DNDEBUG -g -O3 -Wall -DPY_ARRAY_UNIQUE_SYMBOL=MPL_ARRAY_API 
-DPYCXX_ISO_CPP_LIB=1

line_profile_aa profile() { return *m_profile; }
^~
1 error generated.

error: command '/Developer/usr/bin/clang' failed with exit status 1

If I do:

CC=gcc python setup.py build

then things work fine, but I just wanted to raise the point that the C files do 
not compile successfully with clang at this time (but this seems to be the 
default compiler on 10.7).

Cheers,
Tom

It looks like a bug in agg that the stricter clang is picking up.  If 
you change agg24/include/agg_renderer_outline_aa.h:1368 to read:

const line_profile_aa profile() { return *m_profile; }

does that help?  (There's probably other cases like this behind it).

I don't have a complete OS-X environment right now to test with, or I'd 
see what the other issues were myself.

I got my OS-X machine going again -- I'm looking into this further now.

2012-02-23 Thread Michael Droettboom

It seems this was the only source of errors.  There is a pull request here:

https://github.com/matplotlib/matplotlib/pull/713

There are plenty of warnings that should probably also be dealt with, 
but this at least allows compilation to complete for now.
