The package liblapack-devel (LAPACK library for linear algebra
operations, see
https://cygwin.com/cgi-bin2/package-cat.cgi?file=x86_64%2Fliblapack-devel%2Fliblapack-devel-3.8.0-1&grep=cblas)
contains the header file usr/include/cblas.h (among others), library
files as usr/lib/libblas.a, usr/lib/liblapack.a etc. as well as the file
usr/lib/pkgconfig/cblas.pc . The command `pkg-config --libs cblas`
returns "-lcblas". However, no library file libcblas.a is present, causing
building of some software packages depending on this library to fail.
for historical cygwin package reason cblas is merged with blas,
they are both inside
/usr/lib/libblas.a
/usr/lib/libblas.dll.a
It seems I forgot to amend the cblas.pc to return "-lblas" when
it was added to the lapack package.
Am I missing something during Cygwin installation?
Falk
I will amend at next release, as workaround you can
modify usr/lib/pkgconfig/cblas.pc manually
