How Do I launch a Native Linux application from Within Wine

[Craig macLeod]

As the subject says,
    I have a Windows application and I wish to run a native linux application from withing it. The main Win32 API calls for running another apllication are

ShellExecute
WinExec
CreateProcess

I have tried calling a native linux program with these (nautilus) and it consistently fails. Do I need a fully specified path (nautilus is in the search path mind you)?

It either does nothing or hangs Wine when I try calling these applications. I assume Wine is running the application as if it is a Windows app and failing.

Thanks for any help in advance.

I just tried it, and it works.
Here's what I did:
copied example CreateProcess code from
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/bas...
Modified it to use an absolute path, e.g.
    CreateProcess( NULL,  TEXT("c:\\windows\\MyChildProcess"), ...
since it didn't seem to work otherwise (probably a PATH problem).
Created a shell script with that name, e.g.

$ cat >  .wine/drive_c/windows/MyChildProcess <<_EOF_
#!/bin/sh
xeyes
_EOF_
$ chmod 755 .wine/drive_c/windows/MyChildProcess

Compiled the demo app with msvc, ran it with wine, voila!  xeyes are
following me around on the screen.

I'd say that you're free to use a linux syscall to do whatever you want, 
including forking the process and exec'ing the linux program. That's the 
beauty of wine. You have win32 *and* linux APIs available at the same time.
