Hi everyone, I finally merged the generalised ufunc patches that awaited comment as the gen_ufuncs branch. Please review the changes on trunk, and let me know if problems occur. One of the tests fail on FreeBSD 64: ERROR: Failure: ImportError (/tmp/numpy-buildbot/b12/numpy-install/lib/python2.4/site-packages/numpy/core/umath_tests.so: Undefined symbol "cblas_dgemm") Is there any reason why blasdot should work fine, but that this should be broken? Regards Stéfan

PyUFunc_FromFuncAndDataAndSignature needs to be moved to the end of the list.
One of the tests fail on FreeBSD 64:
ERROR: Failure: ImportError

Is there any reason why blasdot should work fine, but that this should be broken?
Hmm..... Chuck

The obvious question is what is umath_test.so :) We don't generate this file AFAIK, and I certainly cannot see it mentioned anywhere in numpy source code (and neither in my mac os X or linux installation). FreeBSD would also require some minor modifications to numpy.distutils, I believe. I have just noticed a bug which may be related in numpy.distutils on a fresh ubuntu install, where numpy uses the C compiler to link atlas when no fortran compiler is available (it should fail instead, since we use the fortran interface in that case, and that cannot work without some fortran support, obviously).

I see this error also when building without Atlas, it goes away if Atlas is used. It is probably a name/configuration problem. Chuck
