Hi, I just tried to port my code to the new SciPy (scipy 0.4.7.1715 / numpy 0.9.7.2248). I got some problems with weave which are usually hard to track down. So I looked at the tests: scipy.test(10, 10) runs without any errors. But I was really surprised when I got a few errors running: scipy.weave.test(1)   Found 16 tests for scipy.weave.slice_handler   Found 0 tests for scipy.weave.c_spec   Found 9 tests for scipy.weave.build_tools   Found 0 tests for scipy.weave.inline_tools   Found 1 tests for scipy.weave.ast_tools   Found 0 tests for scipy.weave.wx_spec   Found 2 tests for scipy.weave.blitz_tools building extensions here: /home/bittrich/.python23_compiled/m15   Found 1 tests for scipy.weave.ext_tools   Found 3 tests for scipy.weave.standard_array_spec   Found 26 tests for scipy.weave.catalog   Found 74 tests for scipy.weave.size_check   Found 0 tests for __main__ ................warning: specified build_dir '_bad_path_' does not exist or is not writable.

So there are no problems with weave while using old scipy (debian stable package). Best regards, Lars
