py26-pyqt4 v4.5.1_0 configure error

[jrminter@…]

I tried to upgrade several ports today. qt4-mac v. 4.5.2_0 built and upgraded just fine. The upgrade of py26-pyqt4 4.4.4_1 to 4.5.1_0 failed at the configure stage with this message:

I thought both of these were GPL versions...

I patched the configure.py to allow it to run (by ignoring the license check). But then compilation fails further on, failing to link to libpng ... but libpng exists in /usr/lib which should be part of the standard link path ...

Sorry, thats rubbish from me, libpng is in /opt/local/lib. This will compile if a -L${prefix}/lib is added to the g++ line. The Makefile is generated by qmake so somehow qmake needs to be told to that ${prefix}/lib should be a searched library path.

Would a setting a symbolic link in the normal search path work? Also, where did you find the configure.py file, and exactly what modification did you make to it? (sorry, I R noob, I don't know this stuff.)

Patch files attached to work around problem. Note that py26-qt4 will then fail to compile until ticket  http://trac.macports.org/ticket/20241 is resolved

The very same problem with py25-pyqt4 v4.5.1_0:

Error: Unable to upgrade port: 1

Should I open an individual ticket?

[lukas.polivka@…]

This error is apparently caused by Qt 4.5.2 licensing change and it most probably breaks all pyqt4(-4.5.1) ports.

It is fixed upstream in the upcoming PyQt4 4.5.2:

2009/06/26 17:40:39 phil Fixed the license checks for Qt v4.5.2.

 http://www.riverbankcomputing.co.uk/static/Downloads/PyQt4/ChangeLog-4.5.2-snapshot-20090712

Maybe py??-pyqt4-devel ports with this snapshot should be created until 4.5.2 is released?

404 not found.

Maybe py??-pyqt4-devel ports with this snapshot should be created until 4.5.2 is released?

Instead, could the specific change that was made to fix this be identified and applied to the existing ports?

[dh@…]

Attached is a solution to the problem (portfile.diff, patch-configure.py). It upgrades the version to 4.5.2 and patches configure.py to correctly link the qtdesigner plugin. It does not require any resolution of ticket 20241 (which should probably be closed as invalid/irrelevant).

Similar patches will need to be applied to py25-* and py-*

dh - I have been trying to use your patches and have run into a problem. I followed the examples in the documentation and set up a local portfile repository and successfully applied the Portfile patch and placed the patch-configure.py in the same directory. When I run port "install py26-pyqt4" I get the following error:

<p> ---> Attempting to fetch patch-configure.py from  http://distfiles.macports.org/py26-pyqt4

<p>It is obviously failing to find the local patch file. I can't seem to find how to fix this in the documentation. I would greatly appreciate a brief howto.

<p> Thanks,

<p>John Minter

dh and others - please ignore my last. I figured out that patch-configure.py had to be in a "files" subdirectory in my local py26-pyqt4 portfile directory. Everything built and installed. Thanks for your help.

Following r54054 this builds for me now against Qt-4.5.2, thanks
