I ran 'make check' and everything seems to be working It says '1 test passed' 42 times, and twice it says 'All 2 tests passed' I'm using the gsl version 1.14, and I installed it using the make utility, No other version of gsl has been previously installed on this computer. My sourcecode which is taken directly from http://www.gnu.org/software/gsl/manual/html_node/Example-programs-for-vectors.html looks like. //file start #define GSL_RANGE_CHECK_OFF #include <stdio.h> #include <gsl/gsl_vector.h> int main (void) { int i; gsl_vector * v = gsl_vector_alloc (3); for (i = 0; i < 3; i++) { gsl_vector_set (v, i, 1.23 + i); } for (i = 0; i < 100; i++) /* OUT OF RANGE ERROR */ { printf ("v_%d = %g\n", i, gsl_vector_get (v, i)); } gsl_vector_free (v); return 0; } //fileend When I have GSL_RANGE_CHECK_OFF in the file, the compiler complains if I also supply the -DGSL_RANGE_CHECK=0 in the command line. gcc -lgsl gslRangeCheck.c -lgslcblas -DGSL_RANGE_CHECK=0 In file included from /usr/include/gsl/gsl_vector_complex_long_double.h:27, from /usr/include/gsl/gsl_vector.h:4, from gslRangeCheck.c:4: /usr/include/gsl/gsl_check_range.h:47:4: error: #error "cannot set both GSL_RANGE_CHECK and GSL_RANGE_CHECK_OFF" thanks for you help _______________________________________________ Help-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gsl
