I'm trying to use the f2c'ed lapack .so (libclapack.so).
I have tried to build it from source (from http://netlib.org/clapack),
also tried to build it though gentoo portage. All the required libs
(libblas, libcblas, libf2c) are loaded successfully, but loading
libclapack leads to error "undefined symbol: f2c_ctrmv".
BTW, it is linking well with C code.

If you have this library (.so file), and it is not difficult for you,
please tell if it works on your system.

also,
I tried not also the latest version (3.2.1), but also 3.1.1 and 3.0.0
the result was similar (another ondefined symbol).

32 bit machine, sbcl 1.0.37

This reminds me of a problem I had when linking fortran code to
sbcl.

When I created the library using intel's compiler (ifort), I got a
similar error message as you.
I then switched to the gfortran compiler, the error went away, and the
code ran.

I suspect the reason is that the compiler expects the code to run in
conjunction with another library. Googling f2c_ctrmv suggests it your
error may be related to blas.

Good luck

Thanks for answer.

But this is GCC, the First and the One. Building CBLAS CLAPACK does
not need fortran compiler.
Googling f2c_ctrmv brings nothing.

Mirko, was you problem dependent on sbcl version?

May be, somebody has a working build of libclapack.so?

That is funny (lately I am finding google stochastic). I found
`f2c_ctrmv' mentioned here:

http://www.netlib.org/clapack/clapack-3.2.1-CMAKE/INCLUDE/blaswrap.h

Can you check (use `nm') whether libcblas has the `f2c_ctrmv'?

I did not check it across multiple versions.

Did you check lla, Tamas Papp's lappack port? AFAIK he has it running
on sbcl and is not porting it to other systems.
