Re: [Matplotlib-users] Build matplotlib 0.98 on OSX
You don't have to do everything that I did, but I have libpng and whatnot installed in /usr/local for other purposes anyway, and I didn't have a particular need to build a universal binary version of matplotlib. Furthermore, using GCC 4.2, while forcing one to get rid of Wno-long-double (an Apple-only thing anyway, and I think it's bad practice to include assumption of such options in a Makefile), allowed me to keep -O3 since it does not have that particular bug. So IF you want to keep the O3 optimisation, then you should install the 4.2 compiler, make sure it gets used, and eliminate the -Wno-long-double flag from the Makefile. No other changes necessary relative to the standard instructions. I've filed a bug report with Apple about the problem with their GCC 4.0.1 in Xcode 3, and as soon as I can get my bug reporting ability up and running again (login has been wonky lately), I'm following up with some additional information they asked for. I'm sorry if I caused some confusion with my personal preferences.

Re: [Matplotlib-users] Build matplotlib 0.98 on OSX
I just used the default 10.5 compiler. I didn't use -Os for the whole run though. I would just copy the gcc command on the files where it failed and replace -O3 with -Os. Kind of lame, I know, but most the build I did was ran with -O3. - Charlie On Thu, Jun 5, 2008 at 8:19 PM, Christopher Barker [EMAIL PROTECTED] wrote: Christopher Burns wrote: Is this really the current solution to building matplotlib on OSX, installing a new compiler and hacking the python Makefile? No, I don't think so. I haven't built it in a while, but I think the OP chose to install 4.2 for some other reason, and maybe had to patch the Makefile because of that.

Re: [Matplotlib-users] Build matplotlib 0.98 on OSX
I'm sure that would work, but John's make target 'build_osx105' is much easier, particularly for end users. $ make build_osx105 That's it. Unpythonic in it's appearance, but sets the required CFLAGS and calls setup.py. On Fri, Jun 6, 2008 at 7:41 AM, Charlie Moad [EMAIL PROTECTED] wrote: I just used the default 10.5 compiler.

What Charlie is saying is my solution will result in a slower mpl than his, since my solution uses a lower optimization level for all files, and he uses the lower level only on the problematic files. But the make solution has the advantage of being a one step automatic build, and I'm not looking for great performance on my laptop usually... JDH - Check out the new SourceForge.net Marketplace.

Re: [Matplotlib-users] Build matplotlib 0.98 on OSX
'make build_osx105' worked great, thank you! Sorry I didn't see that earlier.

Is there an easier solution? I'm reluctant to upgrade to gcc 4.2 and loose the ability to build other packages I need. An upgrade to 4.2 is not required. On the svn trunk (0.98) there is a bug in the apple gcc compiler with our agg extension that causes a compiler error if the optimization level is -O3. You can work around it by using -Os instead. I build with the default apple compiler and have a line in the Makefile in the mpl src dir that reads:: build_osx105: CFLAGS=-Os -arch i386 -arch ppc LDFLAGS=-Os -arch i386 -arch ppc python setup.py build Some of the other suggested tricks like editing the Python Makefile configs may be handy so you don't have to pass around CFLAGS and LDFLAGS, but they are in no way required. My build notes are at: http://ipython.scipy.org/moin/Py4Science/InstallationOSX but I need to update them with the info in this email. Don't ignore the pkgconfig stuff, as it is helpful to help find freetype and libpng.
