1. Double trouble

I have a new version of EuGtk which runs on both 32 and 64-bit processors (at least the ones that I own), using Euphoria 4.1.0. Download EuGTK4.6.0: https://sites.google.com/site/euphoriagtk/

There remains one problem. A few GTK routines require 6 or 7 doubles to be passed to them. The 32-bit version of Eu 4.1 handles this just fine, but the 64-bit goes astray. Here's a test to show what happens:

// dbl.c 
 
#include <stdio.h> 
 
void display_double(double d1, double d2, double d3, double d4, double d5, double d6) 
{  
	printf("One %g\n",d1); 
	printf("Two %g\n",d2); 
	printf("Three %g\n",d3); 
	printf("Four %g\n",d4); 
	printf("Five %g\n",d5); 
	printf("Six %g\n",d6); 
} 

--dbl.ex 
 
include std/machine.e 
include std/dll.e 
 
atom lib = open_dll("./dbl.so") 
 
atom fn = define_c_proc(lib,"displaydouble",{C_DOUBLE,C_DOUBLE,C_DOUBLE,C_DOUBLE,C_DOUBLE,C_DOUBLE}) 
 
c_proc(fn,{1.1,1.2,1.3,1.4,1.5,1.6}) 

Eu 4.1.0 in 64-bit version prints a bogus value for Six. Fortunately, this problem only affects a couple of Cairo graphic routines.

Looks like we weren't using all of the registers correctly. New 4.1 64-bit eubin (13MB).

I just tried it and it downloads fine for me.

Just to be clear, the link I posted is hosted right here on openeuphoria.org. And it also works for me.

It's apparently blocked by the school. I got it from the other location. THANKS!
