Just to make sure I understood correctly: With a WoW64 (built with
If I *create* a new prefix then I decide about its arch (with the
default being win64) by using WINEARCH=...
But when I use an existing wineprefix, either with /usr/bin/wine
(vanilla upstream) or with a Desktop launcher, then Wine automatically
The latter indeed does not work with our current wine64. It could be
done with a system.reg test in our wine-script though.
I'm no programmer, but in server/registry.c I found:
----- snip -----
/* load a global option from the input file */
static int load_global_option( const char *buffer, struct file_load_info
const char *p;
if (!strncmp( buffer, "#arch=", 6 ))
enum prefix_type type;
p = buffer + 6;
if (!strcmp( p, "win32" )) type = PREFIX_32BIT;
else if (!strcmp( p, "win64" )) type = PREFIX_64BIT;
----- snap -----
I have a feeling that Wine is doing the same like grep'ing system.reg
for #arch=win32 or #arch=win64. In that case I'd feel comfortable with
doing this in the wine script (unless^Wuntil we have a real WoW64
build). Better than having launchers that don't work and which don't
give the user any hint what's wrong.
Alternatively we could write the arch information in the launcher.
Mike, for a "back to back" WoW64 build you thought about cross-compiling
on amd64, or about copying results from one arch to the other/having the
amd64 packages as build-dependency for the WoW64 build on i386?
