Native Client version

[mitcoes]

Native client is a Google Chrome browser tech.
http://www.naclbox.com/ has ported DosBox to this tech, and works fine.

If it is possible porting Wine to this Native Client tech Installing it as a Chrome app and using the browser as desktop can be easier for most people.

Linux users are good with configs, but OSX users usually not.

I do not know if it is possible without a lot of work, or if it would be easy, but I think it is a good idea if it works.

IIRC i once tried it, but i think nacl disallows syscalls (or at least chrome checks for them) and Wine uses them quite a lot, that's already a major problem. Further it didn't build for various missing things.

i tried it for fun, but it stops very early:

i686-nacl-gcc -g -O2 -o makedep makedep.o

It won't work; even if we recompiled wine with the
nacl tools, user apps that use native code would
need recompiling, too.

[André H.]

really? if you mean win32 apps than they should run on x86 at least in my understanding.
we may need something like winechrome.drv to display things, but for now there are other problems...

André H. Wine catchs syscall faults at times and processes them. Problem is nacl also catchs syscall faults and a syscall fault equals application termination.

So yes fix up wine and still a stack of windows applications will never work in nacl. Also then you have wine huge dependency list.

DosBox is a full blown emulator. Wine is not.

Don't underestimate how badly behavied windows applications are. Like trying to alter flags at particular memory addresses directly.

You can bet some win32 and win64 are going to do stuff the sandbox will take offence to.

Yes you have better olds making Linux applications work inside it than windows. So far no one has done a chromium inside chrome. That would be funny.

@André H.:
Regarding this NaCl link issue:

Code: Select all

/home/pierre/lighthouse/src/corelib/io/qfilesystemengine_unix.cpp:655: undefined reference to `getcwd'

This solution solved the same issue for me:

Try linking with -lnosys.

indeed that helps, but a bit later i get:

I don't think that making Wine work in Google Native Client will be an easy task.
There must be a lot of work, since Wine assumes that you are in a system running a X11 server and not Chrome.
This would be great if we get a port of Wine to run in Chrome, but I think that it will take a lot of effort from the developers, since there are many restrictions in NaCl that should prevent Windows application to run on it and many of these restrictions are related to security.

[asadpakistani]

Wine assumes that X11 is running, but keep in mind that chrome native client is a virtual machine container so X11 CAN RUN IN IT...

So essentially the road map is to compile a a mini linux distribution for nacl with a very trimmed down x11, and then compile wine for it
