Subject: GSL 1.7 for Windows : .NET 2003 - msg#00010List: lib.gsl.generalI was having problem with the cygwin binaries of GSL 1.6 under windows with Microsoft Visual Studio .NET 2003. I have compiled the whole GSL 1.7 library under windows. Sources and binaries could be found at : http://david.geldreich.free.fr/dev.html Please feel free to contact me if you have any problem with this port. Best regards. Thread at a glance:

I would have expected to see something like double f(double omega, void *vparams) { double *params = (double *) vparams; double Wg = params[0]; double omega_0 = params[1]; // etc. Make sure that f() evaluates to the expected result for particular values of omega and parameters. -- mj Next Message by Date: click to view message previewinstall gsl on alpha under tru64Hi there, does anyone have experience regarding the installation of gsl on alpha machines running tru64 unix 5.1.B?

I have a problem using qawc.
