Problems with universal Python 2.4.3's distutils
by Anand Patil Nov. 5, 2006

Nov. 5, 2006

Hi all, I'm running Universal Python 2.4.3 on my Powerbook G4 under OS X 10.4.8. I'm trying to install a package called mpi4py (MPI for Python), and Universal Python's distutils seem to be causing some trouble. It looks like the -arch i386 argument is confusing the linker somehow because my computer is a PPC. Also, I'm not sure what the library rt is, but there doesn't seem to be such a thing on my computer (though I've installed the latest version of Xcode). Does anyone know how I can resolve this? Sorry if this is OT, I didn't know where else to post. Thanks for any advice, Anand Patil Anand-Patils-Computer:~/Desktop/mpi4py-0.4.0rc1 anand$ python setup.py build --mpi=mpich2 running build running build_py running build_ext MPI configuration: from section 'mpich2' in file/s 'mpi.cfg' MPI C compiler: /usr/local/mpich2/bin/mpicc MPI C++ compiler: /usr/local/mpich2/bin/mpicxx building 'mpi4py.libmpi' extension /usr/local/mpich2/bin/mpicc -arch ppc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -fno-strict-aliasing -Wno-long-double -no-cpp-precomp -mno-fused-madd -fno-common -dynamic -DNDEBUG -O3 -I/usr/local/mpich2/include -I/Library/Frameworks/Python.framework/Versions/2.4/include/python2.4 -c mpi/ext/libmpi.c -o build/temp.macosx-10.4-fat-2.4/mpi/ext/libmpi.o /usr/local/mpich2/bin/mpicc -arch ppc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -g -bundle -undefined dynamic_lookup build/temp.macosx-10.4-fat-2.4/mpi/ext/libmpi.o -L/usr/local/mpich2/lib -L/usr/local/mpich2 -lmpich -lrt -o build/lib.macosx-10.4-fat-2.4/mpi4py/libmpi.so /usr/bin/ld: for architecture i386 /usr/bin/ld: warning /usr/local/mpich2/lib/libmpich.dylib cputype (18, architecture ppc) does not match cputype (7) for specified -arch flag: i386 (file not loaded) /usr/bin/ld: can't locate file for: -lrt collect2: ld returned 1 exit status /usr/bin/ld: for architecture ppc /usr/bin/ld: can't locate file for: -lrt collect2: ld returned 1 exit status lipo: can't open input file: /var/tmp//ccFhLQNI.out (No such file or directory) error: command '/usr/local/mpich2/bin/mpicc' failed with exit status 1

How to run an app bundle as root?
by Arve Knudsen Nov. 3, 2006

Nov. 3, 2006

Yes, that would be my ideal approach. I simply don't have the time to implement this at the moment however (I need a running prototype). Besides, the OS X Installer operates this way already.

How to run an app bundle as root?
by Arve Knudsen Nov. 3, 2006

Nov. 3, 2006

Hello I'm writing a custom installation tool for OS X, which needs to run with root privileges. The installation tool is packaged into an app bundle by way of py2app. What I basically need to know is the best way of attaining root privileges in the tool, must this be done with AuthorizationExecuteWithPrivileges? I first tried this approach, writing a wrapper script which executes the main script in a privileged Python process. This doesn't quite work however, the resulting window behaves completely different from what one would expect. That is, it can't get focus and I can't command-tab to it. I thought of another approach, which is to first run a privileged program which setuid's the bundle executable, and then re-execute the bundle. Would this be a good approach, and how can I execute the bundle programmatically? Thanks, Arve Knudsen

IDLE and MacPython 2.5
by Rodney Somerstein Nov. 2, 2006

Nov. 2, 2006

I downloaded Python 2.5 yesterday and am having a problem with the included IDLE. If I launch IDLE by double-clicking, it shows up in the task bar, then immediately goes away. I see no windows, menus, etc. for the program. If I type IDLE at the command line, IDLE 1.2 launches with no problem. The icon in the task bar appears to be Python Launcher in that case, not IDLE. If I launch the IDLE.app from MacPython 2.4 by double-clicking, it launches IDLE 1.1.3 with no problems. Does anyone have any suggestions? Is IDLE.app broken under MacPython 2.5? While I can launch it from terminal, it is definitely more convenient to just double-click. I am using IDLE because I have been working my way through the O'Reilly Learning Python book at a glacial pace over the last year or more and it is nice to have a simple Python-aware interactive editor. -Rodney -- Rodney Somerstein Always remember that you are unique... rodneys(a)io.com just like everyone else.
