py-pyobjc2: unrecognized command line option "-Wno-long-double"

[brian.hudson@…]

I ran: ports install matplotlib

This eventually failed:

I removed -Wno-long-double from setup.py, then was able to successfully install py-pyobjc2.

Apologies if I haven't opened this all properly, this is my first foray into such things, and I based this off of a similar problem I saw listed in Ticket #18800

Do you specifically need Python 2.4? On 10.6, it's best to use Python 2.6+.

[brian.hudson@…]

Apologies - as soon as I posted, I realized I should have previewed. I'm not familiar with WikiFormatting, and I had just copied and pasted. I'll be sure to preview in the future.

I don't have a specific requirement for Python 2.4. What I'm actually trying to do is use Python 2.7.1 (although anything >= 2.6 would probably be fine, I was just trying to get the latest stable) and get Matplotlib working along with IPython. I think Python 2.4 came along with some of the dependencies / packages that were automatically brought in.

Then you don't want py-pyobjc2, which (as are all py-* ports) for Python 2.4; you want py27-pyobjc which is for Python 2.7.

[brian.hudson@…]

Thanks for the explanation of py-module versioning. I now see that if I wanted matplotlib for python 2.7, I should have installed py27-matplotlib. However - I would have still expected the command "port install matplotlib" to have successfully installed all necessary dependencies for matplotlib on top of python 2.4 without encountering the compile error that I hit.

[ryandesign (Ryan Carsten Schmidt)]

Note there is no port "matplotlib". There are ports py-matplotlib, py25-matplotlib, py26-matplotlib and py27-matplotlib, for Python versions 2.4, 2.5, 2.6 and 2.7, respectively. Yes, you're right to expect port installs to work, unfortunately some ports are broken on some systems. In this case, Python 2.4 and 2.5 are very old versions, and don't work well on 64-bit systems, such as Snow Leopard. We should probably make a concerted effort to remove Python 2.4 and 2.5 from MacPorts at this point in favor of newer versions.
