lisaem: tries to build as 64-bit against wxWidgets-2.8

[mojca (Mojca Miklavec)]

It looks like lisaem tries to be built as 32-bit despite r110329.

Please note that it's also not excluded that it's a bug in the wxWidgets PortGroup.

The flags being used are:

WX_CONFIG='/opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/2.8/bin/wx-config'
LIBRARY_PATH='/opt/local/lib
MACOSX_DEPLOYMENT_TARGET='10.6'
CC='/usr/bin/gcc-4.2 -arch x86_64 -Wno-error -Wno-return-type'
CXX='/usr/bin/g++-4.2 -arch x86_64'

This:

wxWidgets.use       wxWidgets-2.8

should trigger the code

universal_variant   no
supported_archs     i386 ppc
compiler.blacklist  clang

from the PortGroup, but maybe something is broken.

Yes, because of #40290.

[ryandesign (Ryan Carsten Schmidt)]

At least, that's part of the problem. I'm on Mountain Lion and I have wkgtk-2.8 installed +universal, and lisaem failed to build because wxgtk-2.8's -arch flags leaked into the build. When I removed the -arch flags from wx-config, I was able to build lisaem on Mountain Lion.

But this bug report is about Snow Leopard, which is using wxWidgets-2.8 instead, so this may be a different problem. I have not tested on Snow Leopard yet.

[mojca (Mojca Miklavec)]

Oh, sorry. I'll commit it, but I don't dare to make a blind commit without testing based on recent experience ;).

But anyway, judged from CC='...' in the environment this problem seems to happen before any configuration takes place at all. I don't think that the flags passed by MacPorts have anything to do with faulty wx-config.

I didn't realize wxWidgets.use would change supported_archs. That means any use of get_canonical_archflags must occur after wxWidgets.use is called. Fixed for lisaem in r110352 but I don't know if other ports have the same issue.

[mojca (Mojca Miklavec)]

r110352 you mean? Thank you, that lead to a successful build on Snow Leopard on the buildbot.

As for the other ports: the only ports that mess with archflags are:

• py-robotframework-ride, broken (#40297)
• py-wxpython-2.8, but I think that it's done properly there because there is duplicated code
• wxWidgets itself uses set archs [join ${configure.universal_archs} ,] for universal (I think this is not problematic)
• plplot where wxWidgets-3.0 doesn't set any architectures
• esdl which doesn't explicitly include wxWidgets (I don't know how exactly it works)
• relax does something that I don't understand (but it also depends on version 2.9 which should be ok)
