Error with "Preprocess only" option (/E) (version 11.00)

[mangel24]

"cc /E prog.c" works fine with version 10.00. But with version 11.00 I get an error:

"Unable to find or execute POCC.EXE"

prog.c:

I've never used cc.exe so I'm not an expert on its use.  That said, /E is a valid option
for pocc.exe but /E does not appear on the list of options for cc.exe  ( see below ). 
That cc /E partially works may simply be a fluke.

switch /E works once, but after that

option /P works

pocc command line switches in version 10 - match version 11
cc commands match too as MrBcx showed.

I would try using pocc directly with /E if that works it would appear to be an issue with cc.
then try cc after changing to the BIN directory.....because the error seems to be locating POCC

A this issue depends Windows OS version, so hopefully people inform in bug report also a Windows OS version too.

As poide have -x -xml commandline options, people can have several Pelles C versions in same PC 
Just make a zip-package from Pelles C folder to USB-sticks.

I have Pelles C versions from 2.50 ->

EDIT:
Perhaps a safer way to test between versions

Code Select Expand

SET PellesCDirX=C:\code\PellesC11
SET PATH=%PellesCDirX%\bin
SET INCLUDE=%PellesCDirX%\include
SET LIB=%PellesCDirX%\lib;%PellesCDirX%\lib\Win
cc.exe -x -c -E prog.c
PAUSE

Very good point!  Also should check IDE settings because help file indicates cc gets information from IDE not environment variables.
