[GnuWin32-Users] GSL and VB6

[Rui Fernandes]

Hi,   I keep trying to use GSL's dlls with VB6. I'm declaring some test functions like this   Public Declare Function gsl_acosh Lib "libgsl.dll" (ByVal x As Double)   but it gives the error: "Bad DLL calling convention" ( error 49 ) when I call it like   Dim a As Double a = gsl_acosh(0.2)   Does anyone knows what is wrong here? The debug gives the error on the "a=gsl_...". It finds the function, but it doesn't work.   Kind regards,   Rui Miguel Fernandes Porto - Portugal
