I am trying to use GSL 1.0 on an ix86 running an essentially normal RedHat
Linux 7.1 installation (with all of RedHat's published patches applied
to gcc, etc).
Consider the following code snippet:
#include <iostream.h>
#include <gsl/gsl_complex.h>
void main()
{
gsl_complex a = gsl_complex_rect(1.0,2.0);
cout << GSL_REAL(a) << ", " << GSL_IMAG(a) << endl;
GSL_SET_COMPLEX (&a, 3.0, 4.0);
cout << GSL_REAL(a) << ", " << GSL_IMAG(a) << endl;
}
Compiling this with g++ gives:
testcomplex.cpp: In function `int main (...)':
testcomplex.cpp:9: `gsl_complex_rect' undeclared (first use this
function)
testcomplex.cpp:9: (Each undeclared identifier is reported only once
for each function it appears in.)
now consider the snippet:
#include <iostream.h>
#include <gsl/gsl_complex.h>
void main()
{
gsl_complex a;
cout << GSL_REAL(a) << ", " << GSL_IMAG(a) << endl;
GSL_SET_COMPLEX (&a, 3.0, 4.0);
cout << GSL_REAL(a) << ", " << GSL_IMAG(a) << endl;
}
this compiles and gives:
2.10391, 7.02217
3, 4
According to page 18 of the GSL manual
[ http://sources.redhat.com/gsl/ref/gsl-ref_5.html#SEC34 ], the function
gsl_complex_rect should be defined. What's up here?

Hi,
You need the include file gsl_complex_math.h
In case of similar trouble, grep the include files:
(in the /usr/local/include or similar:)
>cd gsl/complex
>grep gsl_complex_rect *.h
gsl_complex_math.h:gsl_complex gsl_complex_rect (double x, double y); /*
r= real+i*imag */
gsl_complex_math.h:gsl_complex_rect (double x, double y)
gsl_complex_math.h:#define GSL_COMPLEX_ONE (gsl_complex_rect(1.0,0.0))
gsl_complex_math.h:#define GSL_COMPLEX_ZERO (gsl_complex_rect(0.0,0.0))
gsl_complex_math.h:#define GSL_COMPLEX_NEGONE (gsl_complex_rect(-1.0,0.0))

According to the same page of the GSL Manual:
The complex types are defined in the header file `gsl_complex.h', while the
corresponding complex functions and arithmetic operations are defined in
`gsl_complex_math.h'.
I made the same mistake some time ago and I take some time to understand why it
doesn't work.

I am trying to use GSL 1.0 on an ix86 running an essentially normal RedHat
Linux 7.1 installation (with all of RedHat's published patches applied
to gcc, etc).
Consider the following code snippet:
#include <iostream.h>
#include <gsl/gsl_complex.h>
void main()
{
gsl_complex a = gsl_complex_rect(1.0,2.0);
cout << GSL_REAL(a) << ", " << GSL_IMAG(a) << endl;
GSL_SET_COMPLEX (&a, 3.0, 4.0);
cout << GSL_REAL(a) << ", " << GSL_IMAG(a) << endl;
}
Compiling this with g++ gives:
testcomplex.cpp: In function `int main (...)':
testcomplex.cpp:9: `gsl_complex_rect' undeclared (first use this
function)
testcomplex.cpp:9: (Each undeclared identifier is reported only once
for each function it appears in.)
now consider the snippet:
#include <iostream.h>
#include <gsl/gsl_complex.h>
void main()
{
gsl_complex a;
cout << GSL_REAL(a) << ", " << GSL_IMAG(a) << endl;
GSL_SET_COMPLEX (&a, 3.0, 4.0);
cout << GSL_REAL(a) << ", " << GSL_IMAG(a) << endl;
}
this compiles and gives:
2.10391, 7.02217
3, 4
According to page 18 of the GSL manual
[ http://sources.redhat.com/gsl/ref/gsl-ref_5.html#SEC34 ], the function
gsl_complex_rect should be defined. What's up here?
