Comment (by jpflori):
For Jeroen:
I guess we should check that the lapack (in fact its dependency
liblapack0) and liblapack-devel packages are installed on Cygwin.
In fact it should be enough to check the existence of the import libraries
for libblas (and liblapack once we get #10508 in) as I do in the spkg-
install file of ATLAS from #10508:
{{{
libraries = ['/usr/lib/libblas.dll.a', '/usr/lib/liblapack.dll.a']
for lib in libraries:
if not os.path.exists(lib):
print '*'*75
print 'Could not locate required file: "' + lib + '".'
print 'On Cygwin you must install the following standard
LAPACK Cygwin packages'
print 'via the Cygwin setup.exe program in the "Math"
category:'
print '* lapack,'
print '* liblapack-devel.'
print 'Alternatively you can try building your own ATLAS by
setting'
print 'SAGE_ATLAS_ARCH to something sensible although that is
not'
print 'officially supported.'
print '*'*75
sys.exit(1)
}}}
Modifying the spkg from #10508 so that it correctly builds will be
slighlty non-trivial, or rather the way we include that in Volker's
autotools stuff needs some thoughts.
