Re: [Help-gsl] Compilation error for BLAS example

[Ralph Silva]

Try this one

$ gcc -Wall -I/usr/include blasExample.c -lgsl -lgslcblas -lm
$ ./a.out

Since you are using BLAS you need to use the respective library.

See
http://www.gnu.org/software/gsl/manual/html_node/Linking-programs-with-the-library.html

or for an alternative BLAS library

http://www.gnu.org/software/gsl/manual/html_node/Linking-with-an-alternative-BLAS-library.html

I hope that helps you.

Ralph.
