Hi,
ther's somthing wrong!
I can't' understand it !!
Last days I've installed blender-dbg and today I've download blender source
Because gdb cannot find source, I've entry the follow commands:
sudo mkdir -p /build/buildd-blender_2.56.1-beta-svn34076-1-i386-oV02K0
sudo ln -s
/home/umberto/Programming/src/blender/blender-2.56.1-beta-svn34076/
/build/buildd-blender_2.56.1-beta-svn34076-1-i386-oV02K0/blender-2.56.1-beta-svn34076
Now if running gdb blender, I get:
umberto@earth:~/Programming/src/blender$ gdb blender

1135 iprop->hardmin= (int)min;
(gdb)
Hmmm Illegal instuction is in line "iprop->hardmin= (int)min;" ???
I will see more clear!!
This is the source code of RNA_def_property_range()
void RNA_def_property_range(PropertyRNA *prop, double min, double max)
{
StructRNA *srna= DefRNA.laststruct;
switch(prop->type) {
case PROP_INT: {
IntPropertyRNA *iprop= (IntPropertyRNA*)prop;
iprop->hardmin= (int)min;
iprop->hardmax= (int)max;
iprop->softmin= MAX2((int)min, iprop->hardmin);
iprop->softmax= MIN2((int)max, iprop->hardmax);
break;
}
case PROP_FLOAT: {
FloatPropertyRNA *fprop= (FloatPropertyRNA*)prop;
fprop->hardmin= (float)min;
fprop->hardmax= (float)max;
fprop->softmin= MAX2((float)min, fprop->hardmin);
fprop->softmax= MIN2((float)max, fprop->hardmax);
break;
}
default:
fprintf(stderr, "RNA_def_property_range:
\"%s.%s\", invalid type for range.\n", srna->identifier,
prop->identifier);
DefRNA.error= 1;
break;
}
}
I will trace blender again:

Hmmm
Isn't clear the little loop between lines 1130 and 1132 of file
rna_define.c and the jump of line 1134.
Look like disallineated source.
Next days i'll recompile and retry. I'll be some luckely?
