Hi
It gives the same message:
Error: Unresolved external '_gsl_rng_taus' referenced from
C:\PROGRAMY\BCC55\PROGS\GSLNEW\PROG.OBJ
I think that, maybe this error is caused by importing types from dll
in borland compiler. All gsl function are exported as stdcall so when
I'm compiling I'm using -ps switch but how tell to compiler that types
gsl_rng_taus and gsl_rng_default are too in stdcall convention? Maybe I
should declare them in borland?
Compiling without -ps switch:
Error: Unresolved external '_gsl_rng_taus' referenced from
C:\PROGRAMY\BCC55\PROGS\GSLNEW\PROG.OBJ
Error: Unresolved external '_gsl_rng_alloc' referenced from
C:\PROGRAMY\BCC55\PROGS\GSLNEW\PROG.OBJ
Error: Unresolved external '_gsl_rng_uniform' referenced from
C:\PROGRAMY\BCC55\PROGS\GSLNEW\PROG.OBJ
Error: Unresolved external '_gsl_rng_free' referenced from
C:\PROGRAMY\BCC55\PROGS\GSLNEW\PROG.OBJ

Replace with (for instance):
gsl_rng * r = gsl_rng_alloc (gsl_rng_taus);
I would try allocating one of the rng_types explicitly, like the
gsl_rng_taus generator above. The default method is based on
environment variables - I have no idea how that works from Windows.

Hello
I'm trying to use GSL in Borland C++ Compiler 5.5 (w2k). I've got
every libs. I tried to compile simple program which use gsl/gsl_rng.h.
And during compilation I've got message (other function such as
gsl_rng_env_setup were consolidated without problems):
Error: Unresolved external '_gsl_rng_default' referenced from
C:\PROGRAMY\BCC55\PROGS\GSL\PROG.OBJ
compiling commands:
bcc32 -ps -c prog.cpp
ilink32 -ap prog.obj c0x32,,,cw32 import32 libgsl libgslcblas
libgsl.lib libgslcblas.lib I've maked from libgsl.dll and
libgslcblas.dll using implib.exe
program code:
#include <stdio.h>
#include <iostream.h>
#include <gsl/gsl_rng.h>
int main (void) {
const gsl_rng_type * T;
gsl_rng * r;
int i, n = 10;
gsl_rng_env_setup();
T = gsl_rng_default;
r = gsl_rng_alloc (T);
for (i = 0; i < n; i++) {
double u = gsl_rng_uniform (r);
printf ("%.5f\n", u); }
gsl_rng_free (r);
return 0; }
