After installing Lapack and Blas, I tried to install lapack++ with failure from http://switch.dl.sourceforge.net/sourceforge/lapackpp/lapackpp-2.5.2.tar.gz

I type ./configure

configure: error: Blas/Lapack was not found.
*** This means Lapack++ and matrix support cannot be compiled.
*** This makes this library unusable. Please get blas and lapack
*** installed. If you do have these installed, use the options
*** --with-blas=<libname> or --with-lapack=<libname> and/or set
*** the env variable LDFLAGS to include the appropriate linker
*** flags.

while I have libblas.a liblapack.a librefblas.a libtmglib.a in my use/local/lin folder.... Can any one help?

Are you sure you have compatible versions of Blas and Lapack installed? Also, what is the output of ../configure when you run it in the extracted directory for lapack++?

Here is the output... For lapack and blas, I have the libraries in /sw/lib/ (installed from Fink) and /usr/local/lib/ (install by myself)... I think it is compatible...

Apparently the lapack++ configuration tool thinks not. Remember, to install from source, the sub-packages need to have their developer modules (headers) installed as well. Even if you have blas/lapack installed, you probably don't have the headers needed, which is what configure is looking for.

I see, it seems that if I can make lapackpp search this folder
/sw/lib
instead of
/usr/local/lib

then it would be done, do you know a way of doing this? thank you:)
