Re: Running text app without X

There is an easy solution for this, just use Xvfb, that is just a dummy virtual X server.

If you already have a X server running on :0 you have to use :1, so you issue the following command:

Xvfb -ac :1 &

after that, just set the variable DISPLAY to :1, and execute what you want.

export DISPLAY=:1
wine c:\\diab\\5.2.1.0\\WIN32\\bin\\dcc -c -o obj/hello.o hello.c

Hope, this helps,

I did spend the last two hours looking for a solution
and trying various things, but to no avail.

I'm trying to run a command-line app (text-only).  It's a
cross-compiler tool for which we only have Windows binaries.
The app works fine, but when I run it (i.e. to compile a
test file), I see:

$ wine c:\\diab\\5.2.1.0\\WIN32\\bin\\dcc -c -o obj/hello.o hello.c
err:imagelist:ImageList_ReplaceIcon no color!
err:imagelist:ImageList_ReplaceIcon no color!
err:imagelist:ImageList_ReplaceIcon no color!
err:imagelist:ImageList_ReplaceIcon no color!
err:imagelist:ImageList_ReplaceIcon no color!
err:imagelist:ImageList_ReplaceIcon no color!
err:imagelist:ImageList_ReplaceIcon no color!
err:imagelist:ImageList_ReplaceIcon no color!

Looked to me like this was trying to do something in X
(even though the app produces NO graphical output),
so I tried overriding the DISPLAY variable to an invalid
display:

$ WINEPREFIX=/work/diab DISPLAY=qqq:0.0 c:\\diab\\5.2.1.0\\WIN32\\bin\\dcc -c -o obj/hello.o hello.c _X11TransSocketINETConnect() can't get address for qqq:6000: Name or service not known
err:imagelist:ImageList_ReplaceIcon no color!
err:imagelist:ImageList_ReplaceIcon no color!
err:imagelist:ImageList_ReplaceIcon no color!
err:imagelist:ImageList_ReplaceIcon no color!
_X11TransSocketINETConnect() can't get address for qqq:6000: Name or service not known
err:imagelist:ImageList_ReplaceIcon no color!
err:imagelist:ImageList_ReplaceIcon no color!
err:imagelist:ImageList_ReplaceIcon no color!
err:imagelist:ImageList_ReplaceIcon no color!

So it's definitely trying to connect to an X server.

Should I expect this?   If so, is there any way to not do this?
This is a compiler, so speed of execution is important (the
resulting app has several hundred files!).   I'd like to
eliminate any extra overhead if possible.
(I know, if performance is a problem then don't use an
emulated environment.....but the wine solution would save
us the $3000 required to update our compiler to a newer
version with Linux support......).

I tried configuring the HKCU\Software\Wine\Drivers
"Graphics"="null", and other settings which didn't seem
to have any effect.   I saw references to the "nulldriver"
graphics driver, but couldn't see how to configure this
(and didn't even know if it would change what I am seeing!).

Any help/hints would be appreciated....

Thanks,
Steve
