Dear all,
I tried to build scipy (cvs checkout) under win32. I installed MinGW and followed quite closely Pearu's instructions at http://cens.ioc.ee/~pearu/scipy/BUILD_WIN32.html However, at the final scipy build stage, when I type
$ msys.py python setup.py build
I obtain the following:
Traceback (most recent call last): File "setup.py", line 125, in ? setup_package(ignore_packages) File "setup.py", line 98, in setup_package parent_path=local_path) File "setup.py", line 59, in get_packages config = setup_module.configuration(*args) File "c:\build\scipy\Lib\integrate\setup_integrate.py", line 21, in configuration raise NotFoundError,'no blas resources found' scipy_distutils.system_info.NotFoundError: no blas resources found
However, my blas library is correctly found when I run system_info.py
Any hints, suggestions ?
How did you specify the locations of blas/lapack libraries? There are several ways to do it, for instance, I use export BLAS=~/src/blas/libfblas.a export LAPACK=~/src/LAPACK/liblapack.a before running msys.py python setup.py build and I just checked, it works with the recent CVS. Or may be you are using ATLAS? Then I would set export ATLAS=~/src/ATLAS/lib/WinNT_P4SSE2 before the build command, and again, it works here. (Of course, the targets of the above environment variables should contain something sensible;) When you run system_info.py, it shows the paths where the blas libraries are looked for, something like blas_info: Replacing _lib_names[0]=='blas' with 'fblas' ( library_dirs = c:/cygwin/home/pearu/src/blas:c:\Py233\lib:C:\ ) ( paths: c:/cygwin/home/pearu/src/blas\libfblas.a ) FOUND: libraries = ['fblas'] library_dirs = ['c:/cygwin/home/pearu/src/blas'] language = f77 To enable these messages also for `setup.py build`, change the line #236 verbosity = 1 in system_info.py to verbosity = 2 How the corresponding `blas_info:..` messages compare when running system_info.py or `setup.py build`?
