Re: using static libraries

[Daniel Rohe <rohe at physik dot RWTH-Aachen dot DE>]

thanks for the reply. following your suggestion I tried the -static option:

source:

#include <gsl/gsl_math.h>

int main()
{
   gsl_isinf(1.0);
}


result:

 >g++ -static -lgsl -lgslcblas gsl_test.c -o gsl_test.out
/usr/tmp/ccpuyfqp.o: In function `main':
/usr/tmp/ccpuyfqp.o(.text+0x11): undefined reference to `gsl_isinf'
collect2: ld returned 1 exit status

I'm pretty sure I'm making some sort of silly mistake again, but I can't see it.


without -static everything seems to be fine:

 >g++ -lgsl -lgslcblas gsl_test.c -o gsl_test.out
 >./gsl_test.out
 >

??
