Has anyone else seen failures in testctypes on older Mac OS X/ PowerPC? Results are below. This is running a build of the trunk from last night: ./configure && make && ./python.exe Lib/test/testctypes.py Note that the test does NOT fail on the Mac OS X/x86 10.4.6 box that I have. It also works on 10.4.?? Power PC. I guess the fix has to wait until I'm able to install 10.3 on my mac, I have the DVDs already but have not yet had the time. If anyone is willing to give me ssh access to a 10.3 box I can try to fix this earlier. I had some problems with my 10.3-capable box, but happily enough it decided to come alive again. I'm currently booted into 10.3.9 and will have a look.

It is a platform bug, RTLD_LOCAL doesn't work on 10.3. The following
C snippet fails with the same error as ctypes: FAIL: dlcompat: unable
to open this file with RTLD_LOCAL. This seems to be confirmed by this
sourcet test file from darwin: http://darwinsource.opendarwin.org/ 10.4.1/dyld-43/unit-tests/test-cases/dlopen-RTLD_LOCAL/main.c.

/* Begin of file */ #include <dlfcn.h> #include <stdio.h>

int main(void) { void* lib;

     lib = dlopen("/usr/lib/libz.dylib", RTLD_LOCAL);
     if (lib == NULL) {
             printf("FAIL: %s\n", dlerror());
     } else {
             printf("OK\n");
     }
     return 0;

} /* End of file */
