Subject: GSL 1.11 available for Windows and Visual Studio .NET 2003 - msg#00064List: lib.gsl.generalI have updated my earlier "port" of the GNU Scientific Library (GSL) for Windows Visual Studio .NET 2003 / Visual C++ 7.1 to its 1.11 version. Binaries and sources could be downloaded at the following URL : http://david.geldreich.free.fr/dev.html The sources implements the tests, all of which pass. The binary package comes with an Visual Studio project example to show how to use the library with Visual. You could use the source package to compile the whole thing under Visual Studio 2005. David.

Previous Message by Date: click to view message previewRe: Help with random samplingHi Tim, there are two problems in your code: 1. You have to add the lines #include <stdio.h> #include <gsl/gsl_randist.h> to the beginning of your program. The header files "stdio.h" and "gsl/gsl_randist.h" contain declarations of the functions you use (printf, gsl_ran_choose). Without this information, the compiler complains about the "implicit declaration", i.e., the appearance of a function without a proper declaration. Additionally, you have to tell the linker where to find the actual code of the functions. In order to do this, you have to add '-lgsl -lgslcblas -lm' to the gcc command line, e.g. gcc test.c -lgsl -lgslcblas -lm 2. The compiler issues a warning about your incorrect use of gsl_ran_choose. Indeed, the first argument to this function should be of type gsl_rng *, not int, see http://www.gnu.org/software/gsl/manual/html_node/Shuffling-and-Sampling.html Maybe you should read the chapter http://www.gnu.org/software/gsl/manual/html_node/Using-the-library.html in the manual and have a look at some example programs in the documentation to get familiar with GSL programming. Regards, Frank Previous Message by Thread: click to view message previewHelp with random samplingHello, I am new to programming, so I apologize for the simplicity of this question. I am trying to learn how to use the gsl_ran_choose and gsl_ran_sample functions, but am having trouble getting them to work. I always get the error "implicit declaration of function 'gsl_ran_choose'". I am just trying to work through simple examples now, and my code is below (for taking an array from 0 to 9, and shuffling those into another array). I would appreciate any help that you could give. Thank you for your time. -Tim Frasier int main(void) { int i, r; int a[10]; int b[10]; r = 10; for (i = 0; i < 10; i++) { a[i] = i; } gsl_ran_choose (r, a, 10, b, 10, sizeof(int)); for(i = 0; i < 10; i++) { printf("\nb[%d] = ", i); printf("%d", b[i]); } printf("\n"); return(0); } Timothy R.
