[Rd] Building a package with BLAS under Windows

[Markus Jochmann]

Hi everybody:

I am writing a package that includes C code that uses the BLAS library. My
Makevars looks like

PKG_LIBS = $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS).

If I check and build the package under Linux on my own computer everything
works fine. However, if I submit the package to win-builder I get the
following error messages:

g++ -shared -s -o bzipl.dll tmp.def ars.o bzipl.o cvm_arrays.o cvm_axpym.o
cvm_cmatrix.o cvm_cmexp.o cvm_cmplx.o cvm_copym.o cvm_cpoly.o cvm_cvector.o

...

To me it looks like somehow the BLAS routines are not called correctly under
Windows.

I would be very grateful if anybody could help me.

Thanks a lot,
Markus.
