Compiling scipy on Windows 32-bit: linker error with libf77blas.a
- by Sridhar Ratnakumar
Has anyone tried compiling SciPy 0.7.1 on Windows using numpy-1.3.0 that was built with the pre-built ATLAS libraries (atlas3.6.0_WinNT_P4SSE2.zip) linked in the installation document.
I get the following linker error, and have no ideas as to how to fix this issue.
$ python setup.py config --compiler=mingw32 build --compiler=mingw32 install --root=i

Does anyone know what could have gone wrong here? Looking for ATL_daxpy, for example, in libf77blas.a resulted in:
$ strings libf77blas.a | grep -i daxpy
_daxpy_
_atl_f77wrap_daxpy_
ATL_F77wrap_daxpy.o/
daxpy.o/ 1081731936 1003 513 100755 420 `
daxpy.f
_daxpy_
_atl_f77wrap_daxpy_
_atl_f77wrap_daxpy_
_ATL_daxpy
There is _ATL_daxpy, but no ATL_daxpy.
