I'm trying to port evolvotron: http://sourceforge.net/projects/evolvotron It build with qmake. Works in Fink. So far, I have this: PortSystem 1.0 name evolvotron version 0.4.0 categories graphics x11 platforms darwin maintainers nomaintainer@macports.org homepage http://sourceforge.net/projects/evolvotron master_sites http://downloads.sourceforge.net/evolvotron/ checksums md5 ab6f3a3247e36ca0024d3837f78bdf6b description "Generative art" image evolver, based on Qt long_description "Generative art" software to evolve images/ textures/patterns through an \ iterative process of random mutation and user- selection driven evolution. depends_lib port:qt3 depends_build port:graphviz port:doxygen patchfiles patch-common.pro patch-evolvotron.pro worksrcdir ${name} configure.args --mandir=${prefix}/share/man destroot.destdir INSTALL_ROOT=${destroot} configure.env QTDIR=${prefix} INSTALLBASE=${prefix} INSTALLPATH= ${destroot}${prefix} build.env QTDIR=${prefix} INSTALLBASE=${prefix} INSTALLPATH= ${destroot}${prefix} destroot.env QTDIR=${prefix} INSTALLBASE=${prefix} INSTALLPATH= ${destroot}${prefix} The patches are as follows: --- common.pro.orig 2005-05-11 11:23:36.000000000 -0700 +++ common.pro 2007-10-10 09:31:18.000000000 -0700 @@ -10,7 +10,7 @@ # INSTALLPATH = /usr/local/bin # For a personal install use something like the next line -INSTALLPATH = /home/$(USER)/bin +#INSTALLPATH = /home/$(USER)/bin ################## # Improved optimisation options from qmake defaults. @@ -79,8 +79,8 @@ # This probably wouldn't be usable until all the strings were moved out of the app - see Qt I18N docs. # Also add gcc threading option (not entirely clear whether this is needed but it doesn't seem to hurt) -QMAKE_CXXFLAGS_RELEASE += -DQT_NO_ASCII_CAST -pthread -QMAKE_CXXFLAGS_DEBUG += -DQT_NO_ASCII_CAST -pthread +QMAKE_CXXFLAGS_RELEASE += -DQT_NO_ASCII_CAST +QMAKE_CXXFLAGS_DEBUG += -DQT_NO_ASCII_CAST ###################################### # Hide those crufty moc_ files away --- evolvotron/evolvotron.pro.orig 2007-10-06 21:02:12.000000000 -0700 +++ evolvotron/evolvotron.pro 2007-10-06 21:03:32.000000000 -0700 @@ -10,6 +10,7 @@ QMAKE_CXXFLAGS_RELEASE += -I../libevolvotron QMAKE_CXXFLAGS_DEBUG += -I../libevolvotron +QMAKE_LFLAGS_RELEASE += -undefined dynamic_lookup target.path = $$INSTALLPATH I get as far as this: ---> Fetching evolvotron ---> Verifying checksum(s) for evolvotron ---> Extracting evolvotron ---> Applying patches to evolvotron ---> Configuring evolvotron ---> Building evolvotron with target all ---> Staging evolvotron into destroot ---> Packaging tgz archive for evolvotron 0.4.0_0 And then I get this: Error: Target org.macports.archive returned: error copying "/opt/ local/var/macports/build/ _opt_local_var_macports_sources_local_graphics_evolvotron/ work/.macports.evolvotron.state" to "/opt/local/var/macports/build/ _opt_local_var_macports_sources_local_graphics_evolvotron/work/ destroot/+STATE": no such file or directory Error: Status 1 encountered during processing. The destroot directory appears momentarily in the work directory, then disappears. Apparently it's being deleted just before the tgz archive is created. I have no idea why. Passing the -d option to 'port install' has no effect on the build output. MacPorts 1.520, Mac OS 10.4.11 PPC, Xcode 2.4.1. Thanks for suggestions.
