linking problems with lapack/lapack++

aoh · ‎05-25-2006

Hey

I'm trying to compile a c++ program using lapack++ (c++ libraries that depend on lapack and blas). I'm trying to build on the SDSC with these specs:

http://www.sdsc.edu/user_services/ia64/tech-summary.html

lapack, blas and lapack++ were already installed by the technicians. When I try to compile, I get these errors:

/usr/lib/liblapack.so: undefined reference to `f_cpstr'
/usr/lib/libblas.so: undefined reference to `f_iob'
/usr/lib/liblapack.so: undefined reference to `f_cpystr'
/usr/lib/liblapack.so: undefined reference to `f_concat'
/usr/lib/libblas.so: undefined reference to `f_stop'

The command I use to compile is this:

icc -I/usr/local/apps/lapackpp-2.4.8/include/lapackpp -L/usr/local/apps/lapackpp-2.4.8/lib -llapackpp -lg2c -lblas -llapack test.cc

So just from looking at it, I see that blas and lapack are attempting to link to some other fortran libraries whose identities I don't have the slightest clue. Are there any linker flags I can add to successfully compile? Any help would be greatly appreciated. Thanks.

Andy

This looks like it was also posted to the C++ forum. For reference here's the solution:
