wxMaxima 0.8.4 build failure

[nhepburn@…]

I have tried to install wxMaxima but not been successful. I have used the command

sudo port update --enforce-variants <pkg_name> +universal

for each of the components like jpeg, tiff, libpng, etc. After doing all that I ran the command to install wxMaxima and was able to get it past installing wxWidgets but then it fails on wxMaxima. I have attached the debug output from the -d switch.

I had the same error but was able to compile it by changing TEMPORALLY macports.conf file (/opt/local/etc/macports). For that, you need first to change the write permission on the file: sudo chmod +w macports.conf and then uncomment the line 59: build_arch i386.

Then you can install: sudo port install wxmaxima by forcing i386 instead of x86_64.

I don't using +universal variant.

You should comment back the line 59 in macports.conf afterwards

I tried that and it worked on my iMac. However, when I tried it on my MBP, it did not. I tried a number of things including completely uninstalling MacPorts and reinstalling. In doing so I made sure that I had the most up-to-date version of xcode installed. When I tried to install wxMaxima again, I had no luck. To force the i386 option, I used sudo port install wxMaxima +i386 It then complained that implicit variants should not be entered and it would be ignored.

Hmmmm.

At the moment wxWidgets is only available for i386 and ppc target while the default target on SnowLeopard is x86_64, thus wxMaxima build fails because macports tries to link with different archs, here's the line from the file you attached:

ld: warning: in /opt/local/lib/libwx_macu-2.8.dylib, file was built for i386 which is not the architecture being linked (x86_64)

You can override this appending build_arch=i386 when building wxMaxima, there's no need to edit macports.conf.

The maintainer could add lines to set configure.build_arch for Intel and PPC machines to avoid having to set it explicitly from command line.

I'm closing this ticket as I'm submitting a version bump to 0.8.6 too.

There's no really need to edit macports.conf, anyway while suggesting changes to it you have to consider that a person could have edited it and thus it's better to quote the actual line you want to change rather than its number.
