f2cblaslapack with single precision?

[Christoph Sprenger]

Hello everyone,

i'm new here and have a first question concerning the building of petsc.
i try to build the libraries with single precision, to reduce the memory 
profile, but having troubles to do so.
i get an undefined reference to saxpy_  and other blas bits and pieces, 
since the f2cblaslapack.tar.gz doesn't seem to contain any single 
precision files.
not sure if i am missing something fundamental though.

here is my config i used to build the lot:
--with-cc=mpicc --with-fc=0 --with-cxx=mpicxx --download-c-blas-lapack=1 
--with-mpi-dir=/home/users/christophs/mpich2 --with-clanguage=cxx 
--with-sudo=sudo --with-shared=1 --with-debugging=1 
--with-scalar-type=real --with-precision=single

it would be great to get a hint whats going on and what the best 
solution for this would be without going through the fortran side of things.
are there other c packages than f2cblaslapack that have the individual 
single precision files ?

apologies for the rather newbie style questions.


Kind Regards,
Christoph
