Hi, Sorry for this ignorant email, but we got confused trying to use 'libnpymath.a' from the mingw builds of numpy:
We were trying to link against the mingw numpy 'libnpymath.a' using Visual Studio C, but this give undefined symbols from 'libnpymath.a' like this: npymath.lib(npy_math.o) : error LNK2019: unresolved external symbol _atanf referenced in function _npy_atanf npymath.lib(npy_math.o) : error LNK2019: unresolved external symbol _acosf referenced in function _npy_acosf npymath.lib(npy_math.o) : error LNK2019: unresolved external symbol _asinf referenced in function _npy_asinf (see : http://nipy.bic.berkeley.edu/builders/dipy-bdist32-33/builds/73/steps/shell_6/logs/stdio) npymath.lib from Christophe Gohlke's (MSVC compiled) numpies does not give such an error. Sure enough, 'npymath.lib' shows these lines from `dumpbin /all npymath.lib`: 00000281 REL32 00000000 4F asinf 00000291 REL32 00000000 51 acosf 000002A1 REL32 00000000 53 atanf whereas `dumpbin /all libnpymath.a` shows these kinds of lines: 000008E5 REL32 00000000 86 _asinf 000008F5 REL32 00000000 85 _acosf 00000905 REL32 00000000 84 _atanf As far as I can see, 'acosf' is defined in the msvc runtime library. I guess that '_acosf' is defined in some mingw runtime library? Is there any way of making a npymath library that will pick up the msvc math and so may work with both msvc and mingw? Sorry again if that's a dumb question, Matthew _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
