[M3devel] new problem on NT386

[Randy Coleburn]

Olaf:
 
I grabbed the new QMachine via cvs and rebuilt & shipped the m3quake
package, then rebuilt reactor (now cm3_ide) to take advantage of it.  I
replaced the exec calls with cm3_exec().
 
At first glance, things were working better in that the output is now
going back to the browser.  Great!
 
But, when I tried to compile a simple "HelloWorld" program, I ran into
some errors.  See attached PDF file.  Does any of this make sense to
you?
 
Note that this same HelloWorld program was compiling before the
QMachine change, its just that the output went to the wrong window.
 
Regards,
Randy

Randy,

I've added compatibilit procedures that should show the old
(queer) behaviour: cm3_exec and try_cm3_exec. The semantics were
changed in this commit:

revision 1.5
date: 2005-10-17 21:00:36 +0000;  author: rillig;  state: Exp;  lines:
+4 -20;
Don't pass the stdout and stderr from child processes through quake.
This makes the quake code simpler and also allows the user to redirect
the stdout and the stderr to different files. Before, the stdout and
stderr had been merged by quake and then printed on stdout.

I think the main goal of the quake changes was to make CM3 and PM3
compatible; but this now seems to break the old Reactor code.
So try if cm3_exec instead of just exec will cure your problem.

You'll have to rebuild the m3quake package of course.

Olaf
