Description

anjuta +python34 fails trying to link to the python34 library:

:info:build libtool: link: /usr/bin/clang -Wl,-undefined -Wl,dynamic_lookup -o .libs/libanjuta-python-loader.so -bundle  .libs/plugin.o   -L/opt/local/lib ../../libanjuta/.libs/libanjuta-3.dylib -lgthread-2.0 -lgmodule-2.0 -lxml2 -lgdl-3 -lgtk-3 -lgdk-3 -lpangocairo-1.0 -lpangoft2-1.0 -lpango-1.0 -lm -lfontconfig -lfreetype -latk-1.0 -lcairo-gobject -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0 -lintl -ldl -framework CoreFoundation -lpython3.4m  -arch x86_64 -Os -arch x86_64 -Wl,-headerpad_max_install_names -arch x86_64   -framework CoreFoundation

Indeed, /opt/local/lib/libpython3.4m is not provided by python34.

However, anjuta +python27 succeeds due to the fact that python27 installs a symbolic link to the python27 library for this purpose in post-destroot

post-destroot {
    set framewpath ${frameworks_dir}/Python.framework
    set framewdir  ${framewpath}/Versions/${branch}

    foreach dir { Headers Resources Python Versions/Current } {
        file delete ${destroot}${framewpath}/${dir}
    }

    ln -s ${framewdir}/share/man/man1/python${branch}.1 ${destroot}${prefix}/share/man/man1/
    ln -s ${framewdir}/Python ${destroot}${prefix}/lib/libpython${branch}.dylib

    foreach unversionedFile {2to3 2to3-2 idle idle2 pydoc pydoc2 python python2 python-config python2-config pythonw pythonw2 smtpd.py smtpd2.py} {
        delete ${destroot}${prefix}/bin/${unversionedFile}
    }

    # remove -arch flags from the config
    reinplace -E {s|-arch [a-z0-9_]+||g} \
        ${destroot}${framewdir}/lib/python${branch}/config/Makefile \
        ${destroot}${framewdir}/lib/python${branch}/_sysconfigdata.py
}

The python34 (and the python3* ports in general) skip this link

post-destroot {
   set framewpath ${frameworks_dir}/Python.framework
   set framewdir  ${framewpath}/Versions/${branch}

   foreach dir { Headers Resources Python Versions/Current } {
      file delete ${destroot}${framewpath}/${dir}
   }

   ln -s ${framewdir}/share/man/man1/python${branch}.1 ${destroot}${prefix}/share/man/man1/

   # Without this, LINKFORSHARED is set to
   # ... $(PYTHONFRAMEWORKDIR)/Versions/$(VERSION)/$(PYTHONFRAMEWORK)
   # (this becomes Python.framework/Versions/3.2/Python) which doesn't
   # quite work (see ticket #15099); instead specifically list the
   # full path to the proper Python framework file (which becomes
   # ${prefix}/Library/Frameworks/Python.framework/Versions/3.2/Python)
    reinplace {s|^\(LINKFORSHARED=.*\)$(PYTHONFRAMEWORKDIR).*$|\1 $(PYTHONFRAMEWORKINSTALLDIR)/Versions/$(VERSION)/$(PYTHONFRAMEWORK)|} ${destroot}${framewdir}/lib/python${branch}/$confdir/Makefile

   # remove -arch flags from the config
    reinplace -E {s|-arch [a-z0-9_]+||g} \
       ${destroot}${framewdir}/lib/python${branch}/$confdir/Makefile
    foreach unversioned {2to3 idle3 pydoc3 python3 python3-config pyvenv} {
        delete ${destroot}${prefix}/bin/${unversioned}
    }
}

Manually creating the link fixes the problem. Is there any reason, that this action should not be added to the python3 post-destroot phase?

Owner: changed from jwa@… to devans@…
Port: anjuta added; python34 python33 python32 python31 removed

Seems to be a build issue with anjuta. I suspect they're using --libs rather than --ldflags:

~ $ /opt/local/bin/python3.4m-config --ldflags
-L/opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/config-3.4m -lintl -ldl -framework CoreFoundation -lpython3.4m

~ $ /opt/local/bin/python3.4m-config --libs
-lintl -ldl -framework CoreFoundation -lpython3.4m

Yep. configure.ac has:

configure.ac:		PYTHON_LIBS=`$PYTHON$PYTHON_VERSION-config --libs`
configure.ac:		AC_SUBST(PYTHON_LIBS)		

anjuta isn't trying to link with the correct ldflags.
