`I'm trying to compile the program listing in the documentation for the
``linear algebra section found here
``http://www.gnu.org/software/gsl/manual/html_node/Linear-Algebra-Examples.html.
``I am getting the following result:
`
gcc matrix_test.cpp
/tmp/ccaENm9Y.o: In function `main':
matrix_test.c:(.text+0x8f): undefined reference to `gsl_matrix_view_array'
matrix_test.c:(.text+0xb2): undefined reference to `gsl_vector_view_array'
matrix_test.c:(.text+0xc1): undefined reference to `gsl_vector_alloc'
matrix_test.c:(.text+0xd3): undefined reference to `gsl_permutation_alloc'
matrix_test.c:(.text+0xfb): undefined reference to `gsl_linalg_LU_decomp'
matrix_test.c:(.text+0x127): undefined reference to `gsl_linalg_LU_solve'
matrix_test.c:(.text+0x152): undefined reference to `gsl_vector_fprintf'
matrix_test.c:(.text+0x160): undefined reference to `gsl_permutation_free'
matrix_test.c:(.text+0x16e): undefined reference to `gsl_vector_free'
collect2: ld returned 1 exit status

`I just cut and pasted the code into a file and ran g++ on it, followed
``by gcc (I renamed the file .c). Both gave the same result. The library
``is installed properly as far as I can tell since it doesn't complain
``about being unable to find the header files.
`
Can somebody either verify this, or help me out?
Thanks :)
Neil
