It has taken me several hours to figure out how to compile an example program 
with Microsoft Visual C++ (.NET 2003), a.k.a. MSVC, and GSL. Since others on 
this list have expressed their frustration at the task, I'll describe my 
solution, which is probably only one of many. This is done in detail for those 
who may not have used MSVC before. Also keep in mind that I am new at this 

1. Download and install
(For more info, see

2. Within VisualStudio, go to File->New->Project, then "Visual C++ Projects," 
then "Win32," then "Win32 Console Application." Enter a name and click "OK." On 
the next screen click "Finish."

3. In the "Solution Explorer," right click on the name of your project and go 
to "Properties."

4. Under Configuration Properties->Linker->General->Additional Library 
Directories, type in "C:\Program Files\GnuWin32\lib"

5. Under Configuration Properties->Linker->Input->Additional Dependencies, type 
in "libgslcblas.a libgsl.a"

6. Under Configuration Properties->C/C++->General->Additional Include 
Directories, type in "C:\Program Files\GnuWin32\include"

7. Under Configuration Properties->C/C++->Code Generation->Runtime Library, 
select "Multi-threaded DLL"

8. Replace the main .cpp file with something like the following:
(Adapted from

#include "stdafx.h"
#include <gsl/gsl_poly.h>

int _tmain(int argc, _TCHAR* argv[])
  int i;
  /* coefficient of P(x) =  -1 + x^5  */
  double a[6] = { -1, 0, 0, 0, 0, 1 };  
  double z[10];

  gsl_poly_complex_workspace * w 
      = gsl_poly_complex_workspace_alloc (6);
  gsl_poly_complex_solve (a, 6, w, z);

  gsl_poly_complex_workspace_free (w);

  for (i = 0; i < 5; i++)
      printf ("z%d = %+.18f %+.18f\n", 
              i, z[2*i], z[2*i+1]);

  return 0;

9. Hit F7 to build your program. You should now be able to run it from the 
command line. You'll get a result like the following:

z0 = -0.809016994374947670 +0.587785252292473360
z1 = -0.809016994374947670 -0.587785252292473360
z2 = +0.309016994374947510 +0.951056516295152980
z3 = +0.309016994374947510 -0.951056516295152980
z4 = +0.999999999999999890 +0.000000000000000000
