see ticket #21530 for a proposed portfile that builds universal. I'm trying this now :) As stated in that ticket, this problem could/should be solved now.

#23320: fail to install wxWidgets-devel +universal on snow leopard -----------------------------------+---------------------------------------- Reporter: klebermagno@… | Owner: jwa@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 1.8.2 Keywords: | Port: wxWidgets-devel -----------------------------------+---------------------------------------- Comment(by cdavis@…): All right, I've worked through this, and there are three distinct issues here: 1. Using dependency options and compiling PCH files You can't do either of those with multiple arch flags. Even if you remove the dependency options, when gcc tries to precompile a header into a PCH given multiple arch flags, it will instead try to compile a regular ol' program instead. (ld will complain that '_main' is undefined.) I fixed it locally by the port belong to the muniversal group. 2. OBJCXXFLAGS isn't set OK, you got past the first problem, and wxWidgets is building just fine. Suddenly, the build stops with an error message. Looking at the log file reveals a bunch of 'file is not of the architecture being linked' messages from ld. Inspecting the files that were compiled wrong reveals something telling: They're all Objective-C++ files! For some reason, wx's build system uses the OBJCXXFLAGS variable instead of the CXXFLAGS variable when compiling an Objective-C++ file. Since the Portfile didn't set OBJCXXFLAGS, no Objective-C++ sources get built for the right architecture. I fixed it by manually playing with the top-level makefile, but the right way to fix this is to set OBJCXXFLAGS in the Portfile during the configure stage. 3. Symlink merging madness Finally, you solved problems 1 and 2 and got the build to finish. Because we put wxWidgets-devel in the muniversal group, now MacPorts will install the two build trees into two destroots, then merge them together. Unfortunately, there's one small problem with that: MacPorts doesn't know how to merge symlink files. Here's a relevant snippet from the log: {{{ :debug:destroot universal: merge: /opt/local/lib/wx-devel/bin/wx-config only exists in /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports .org_release_ports_graphics_wxWidgets-devel/work/destroot-x86_64 :debug:destroot universal: merge: /opt/local/lib/wx-devel/bin/wx-config only exists in /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports .org_release_ports_graphics_wxWidgets-devel/work/destroot-i386 }}} So it knows that both symlinks are there, but it thinks they're distinct. So, it copies each one over to the merged destroot. Unfortunately, copying the second one fails because the file already exists: {{{ :error:destroot Target org.macports.destroot returned: error copying "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports .org_release_ports_graphics_wxWidgets- devel/work/destroot-i386//opt/local/lib/wx-devel/bin/wx-config" to "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports .org_release_ports_graphics_wxWidgets-devel/work/destroot- intel//opt/local/lib/wx-devel/bin/wx-config": file already exists }}} This is as far as I got. One possible solution is to forcibly copy the symlink over. However, I think the real solution is to teach MacPorts to recognize and handle symlinks properly when merging two destroots. -- Ticket URL: <https://trac.macports.org/ticket/23320#comment:9> MacPorts <http://www.macports.org/> Ports system for Mac OS
