Exception in pocc.exe

[HellOfMice]

Not for me

This code calls renamed pocc.exe as poccx.exe
An actual pocc.exe error code not even handled.
A poccx.exe have to have a full path to Pelles C bin folder.
Just a temporary solution to 24H2 problem
- rename original pocc.exe to poccx.exe
- copy fake pocc.exe to Pelles c bin folder

That seems a better solution than what I proposed. I will try. Thank You Timo

Hi Timo


I have renamed the old pocc.exe to poccx.exe and unzipped yours.
I always have the error

Done.

Timo,


When the process exits could you return 0 if No errors found and just 1 if an error, like compiling, has been found.
It is for using ERRORLEVEL in a cmd file


If it is possible. I already ask to Pelle here in this forum.

[TimoVJL]

So you mean if exception don't happen, a real pocc.exe error code returned ?
Isn't it a bit useless thing with 24H2 ?
In working system fake pocc.exe don't even needed.

[HellOfMice]

I can simulate a make


POCC Something.c
IF ERRORLEVEL 1 GOTO FINISHED
POASM Another.asm
IF ERRORLEVEL 1 GOTO FINISHED
POLINK ...
IF ERRORLEVEL 1 GOTO ERRORLINKER
MYPROGRAM.EXE
EXIT
:ERRORLINKER
ECHHO You are bad
:FINISHED
EXIT

EDIT: fake poasm.exe too

I renamed pocc.exe to poccXX.exe and added fake pocc.exe:
I get no error message and the exe file starts. But, my program does not change. I printed "kkkkk" in the program window before the change. After the change to fake pocc.exe, I changed the text to "xxxxx". When I compile I still get program window with "kkkkk".
I switched back to original pocc.exe and compiles. Now the program window opens with "xxxxx" printed.

Unfortunately, fake pocc.exe does not work correctly, but maybe it can be developed further
I look forward to another test!

rename orginal pocc.exe to poccx.exe

With DbgView.exe might be possible to see, if result of GetModuleFileName() and modification have a problem.
I don't use Program Files folder in testings.

Perhaps it's better, that MS develop 24H2 further 

This code might be a problem with paths with spaces

Code: [Select]

DWORD nLen = GetModuleFileName(NULL, szProg, sizeof(szProg));
nLen -= 4;
lstrcpy(szProg+nLen, "x.exe");
OutputDebugString(szProg);


[HellOfMice]

I have a good solution, it runs, no reason too search for other soluce

I made change using a response file for linking


Whatever you do, find or don't find the key to solve the problem, there is a question behind, if Pelle does not come back?
Will us accept to find each time a solution, nice or not?


AMD compiler is free, on Linux and many AMD libraries. There is alsoa profiler like VTune.
Is it a solutiton?

Have I understood correctly:
- Rename original pocc.exe to poccx.exe
- Place fake pocc.exe in the bin folder

[alderman2]

NOW IT WORKS!!
 
I must have done something wrong last time (maybe spaces or something).

THANKS TimoVJL !!
