Probably needs a newer Python version, but I'd rather not add a python build dependency for everyone.

I have installed, to satisfy dependencies: {{{ python27 @2.7.11_0+ucs4 (active) python34 @3.4.4_0 (active) }}}

Can you figure out which version of Python added this?

No. I am merely a Python illiterate. I have no idea what's causing the fault why. -- Ticket URL: <https://trac.macports.org/ticket/50342#comment:2> MacPorts <https://www.macports.org/> Ports system for OS X

The file does `from __future__ import print_function`, which enables this usage of print but only works with Python >= 2.6. Additionally, it specifies a shebang of `/usr/bin/python`, which is probably too old on your system. Replacing the shebang of `src/res2cc_cmd.py` with `#!/usr/bin/env python` would probably fix this if you had python 2.7 installed.

Applying that patch leads to another error: {{{ make[2]: Entering directory `/opt/local/var/macports/build/_opt_local_var_macports_sources_lil.fr.rsync.macports.org_release_tarballs_ports_textproc_doxygen/doxygen/work/doxygen-1.8.10' [ 26%] Generating /opt/local/var/macports/build/_opt_local_var_macports_sources_lil.fr.rsync.macports.org_release_tarballs_ports_textproc_doxygen/doxygen/work/doxygen-1.8.10/generated_src/resources.cpp cd /opt/local/var/macports/build/_opt_local_var_macports_sources_lil.fr.rsync.macports.org_release_tarballs_ports_textproc_doxygen/doxygen/work/doxygen-1.8.10/src && /opt/local/bin/python /opt/local/var/macports/build/_opt_local_var_macports_sources_lil.fr.rsync.macports.org_release_tarballs_ports_textproc_doxygen/doxygen/work/doxygen-1.8.10/src/res2cc_cmd.py /opt/local/var/macports/build/_opt_local_var_macports_sources_lil.fr.rsync.macports.org_release_tarballs_ports_textproc_doxygen/doxygen/work/doxygen-1.8.10/templates /opt/local/var/macports/build/_opt_local_var_macports_sources_lil.fr.rsync.macports.org_release_tarballs_ports_textproc_doxygen/doxygen/work/doxygen-1.8.10/generated_src/resources.cpp File "/opt/local/var/macports/build/_opt_local_var_macports_sources_lil.fr.rsync.macports.org_release_tarballs_ports_textproc_doxygen/doxygen/work/doxygen-1.8.10/src/res2cc_cmd.py", line 40 print("static const unsigned char %s_data[] = " % self.bareName,file=outputFile) ^ SyntaxError: invalid syntax }}} What finally helped building doxygen is changing the setting of `python` from {{{ Name Selected Options ==== ======== ======= clang none mp-clang-3.4 none cython cython27 cython27 none db none db48 none gcc apple-gcc42 apple-gcc42 gcc33 gcc40 mp-gcc48 mp-gcc49 mp-gcc5 none llvm none mp-llvm-3.3 mp-llvm-3.4 none nosetests none nosetests27 none python python25 python23-apple python25 python27 python34 none python2 python27 python23-apple python27 none python3 python34 python34 none }}} to {{{ python python27 python23-apple python25 python27 python34 none }}} -- Ticket URL: <https://trac.macports.org/ticket/50342#comment:4> MacPorts <https://www.macports.org/> Ports system for OS X

So the correct fix would be to add a dependency on Python 2.7 and patch the shebang of the file, but only on platforms where this is necessary.

Can you provide a patch that does this?

To improve my earlier report: I re-started with clean sources, i.e., after invoking `port clean doxygen`. So the only patch necessary is that of the Portfile. IMO it already contains that dependancy, on line #44, doesn't it? It's somehow necessary to make port invoke `port select --set python python27` or such. -- Ticket URL: <https://trac.macports.org/ticket/50342#comment:6> MacPorts <https://www.macports.org/> Ports system for OS X

Ports cannot depend on a certain selection state of `port select`, we would consider that a bug, because the selection mechanism is for users only.

Consequently, we cannot rely on `/usr/bin/env python` being our python after declaring a dependency on python27, and for this reason, we need the patch to the shebang explicitly uses our python.

The only problem is that the CMakeCache.txt file points to the wrong version of Python. Python 2.7 does get installed as part of the Doxygen dependency resolution, but the CMakeCache.txt file still points to "/usr/bin/python", which is at version 2.5. Anyway, I attached the corrected CMakeCache.txt file, which I've verified as working on two different G5 PowerMacs.

Does r149412 fix the problem?

Yes the problem is fixed, doxygen built fine. -- Ticket URL: <https://trac.macports.org/ticket/50342#comment:13> MacPorts <https://www.macports.org/> Ports system for the Mac operating system
