[Lapackpp-devel] compile problem on linux

[<mk...@wp...>]

Hi, sorry to post about my ignorance on linux but I have a problem with linking the lapack/blas/atlas libraries during compilation. There it goes:

g++ -shared -nostdlib /usr/lib/gcc-lib/i486-linux/3.3.5/../../../crti.o /usr/lib/gcc-lib/i486-linux/3.3.5/crtbeginS.o  .libs/dopla.o .libs/dtimmg.o .libs/eigslv.o .libs/genmd.o .libs/laprefs.o .libs/lasvd.o .libs/lautil.o .libs/linslv.o .libs/systime.o -Wl,--whole-archive ../matrix/src/.libs/liblamatrixpp.a ../blaspp/src/.libs/libblaspp.a -Wl,--no-whole-archive  -llapack.2.0 -L/usr/lib -lcblas.3.0 -lf77blas.3.0 -latlas.3.0 -L/usr/lib/gcc-lib/i486-linux/3.3.5 
-L/usr/lib/gcc-lib/i486-linux/3.3.5/../../.. -lfrtbegin /usr/lib/libg2c.so -lstdc++ -lm -lc -lgcc_s /usr/lib/gcc-lib/i486-linux/3.3.5/crtendS.o /usr/lib/gcc-lib/i486-linux/3.3.5/../../../crtn.o  -Wl,-soname -Wl,liblapackpp.so.1 -o .libs/liblapackpp.so.1.12.0
/usr/bin/ld: cannot find -llapack.2.0
collect2: ld returned 1 exit status

The configure script does something like this:

checking if ATLAS should be used... yes
checking for ATLAS library... /usr/lib (libatlas.so.3.0)
checking for f77blas library... /usr/lib (libf77blas.so.3.0)
checking for cblas library... /usr/lib (libcblas.so.3.0)
checking whether ATLAS is usable... yes
checking for cheev_... no
checking for cheev_ in -llapack... no
checking for cheev_ in -llapack32... no
checking for cheev_ in -llapack_rs6k... no
checking for any lapack library... -llapack.2.0

I've got liblapack.so.2.0 in my /usr/lib

My guess is that gcc looks only for lib*.so with -l option and doesn't see lib*.so.*

Is there any way to make it right?

I have Debian/GNU Linux 3.1 with gcc 3.3.5 (Debian)
