As has been previously reported and fixed in some portions of the build process, building on Darwin 8 with gcc-4.0 requires some extra libraries to be passed. When --with-cxx=g++ is specified to configure, and possibly for other flags that make the build process be conscious of C++. Tail of error: gcc -u _PyMac_Error -o python.exe \ Modules/ccpython.o \ libpython2.4.a -ldl /usr/bin/ld: Undefined symbols: ___gxx_personality_v0 collect2: ld returned 1 exit status make: *** [python.exe] Error 1 Fix: Add -lSystem and -lSystemStubs for Darwin 8 to the linker where appropriate. I haven't identified all these spots though.
Logged In: YES user_id=21627 Can you check whether just linking with g++ (instead of linking with gcc, and still not adding -lSystem) also solves the problem? configure is supposed to detect that g++ is needed for linking; if linking with g++ solves the problem, then configure.in must be enhanced to properly auto-detect this case.
Logged In: YES user_id=554287 Firstly, exposing this bug, I discovred, also requires passing --with- pydebug=true. It's fine if you don't compile with pydebug. I'm sorry I did not mention/realize that initially. Secondly in response to loewis comment. It looks like linking with g++ instead of gcc as you eluded to takes care of the problem.

Logged In: YES user_id=21627 Ok. configure should have detected that you need g++ to link. To do so, it compiles the program void foo();int main(){foo();}void foo(){} with g++ (g++ -c), then links the object file with gcc. If that fails, it concludes that g++ is needed. Can you please a) confirm that this specific procedure indeed links correctly, and b) experiment to find out what changes to the program need to be made so that it fails to link because of ___gxx_personality_v0 ? To analyse b), a number of issues have to be considered: it may be that more include files are needed in the test program, it may be that other compiler flags need to be passed, and it may be that more code needs to be added. If you cannot easily make the test case fail, please try to reduce Modules/ccpython so that moves towards the test code.
