Hi Paolo,

Thanks for the report.

You are supposed to include  #include <gsl/gsl_$SOMEFILE.h>, see the manual.

Well, while this could be seen as a bug, your test program is also less than
ideal. First, as stated above, you are constructing the header file the
wrong way. Secondly, you are building it in a less than ideal way. Lastly,
the library invites modularity. Nobody should include all header files just
for the fun of it. 

See for this working example:

address@hidden:/tmp/gsl> cat paolo.c
#include <gsl/gsl_math.h>

int main ( void) {
     printf("test\n");
}
address@hidden:/tmp/gsl> gcc -o paolo paolo.c -lm -lgsl -lgslcblas
address@hidden:/tmp/gsl> ./paolo
test

Can you create an example using the chebyshev header file which actually
fails?  Compiling the actual example from the manual work just fine:

address@hidden:/tmp/gsl> head -10 cheb.c
#include <stdio.h>
#include <gsl/gsl_math.h>
#include <gsl/gsl_chebyshev.h>

double
f (double x, void *p)
{
  if (x < 0.5)
    return 0.25;
  else
address@hidden:/tmp/gsl> gcc -o cheb cheb.c -lm -lgsl -lgslcblas
address@hidden:/tmp/gsl> ./cheb | wc -l
  10000

So unless you can substantiate the bug report, I will probably just close it. 
But I'll pass this on to Brian just in case.

Regards, Dirk
