The use of a go32v2 compiled program (like the go32v2 IDE) with any window bosx (apart for win9X, which seems to work more or less..) is strongly discouraged...
because there are several windows problems related to changings of how Windows emulates the Dos and DPMI support from one version to another, leading to very subtle bugs and crashes that we (developpers) don't have time to understand and circumvent.

If you are interested in such topics, you can refer to the djgpp workers mailing list which is full of such stuff....

Try to use the win32 version of the IDE, unless you really need to use the go32v2 version.
The only good reason to use the go32v2 executable is when you want to debug that executable, but then it is stated even more loudly that windows does not support Dos and DPMI consistently across versions and that this can lead to spurious crashes, even more frequently when debugging.

To other developpers, I think that :
1) the FAQ qhould be visible in the left list on main page of web site.
2) that the above should be added to the 1.8 section.

Target: G032V2
Compiler: FPC 1.0.6
IDE: Free Pascal IDE version 0.9.2
Environment: DOS-Box of WinME

Buggy IDE:

After editing and saving the source of my program, I started grep from the IDE.
In the grep-window appeared the first line. Then the IDE crashes with this message:

"Program generated a signal 290. Save your sources and restart the IDE."

(No chance to save anything at this time..)

FPC double exception, exiting due to signal 0006
FPC invalid opcode at eip=00001FF1
eax=00000000 ebx=005AB910 ecx=00000000 edx=0036375C esi=00000000 edi=0037CEA0
ebp=00000000 esp=00rA707F program=C:\FP106\bin\go32v2\FP.EXE

Since this first crash grep is still unavailable; every call of grep crashes the IDE.

I tried to use 1.1 of FPC. But on my system (Windows XP 2600), IDE not started correctly. Only black screen and no more. I was tried Win32 IDE. 1.0.x work fine.

1.1 is under very heavy development currently and it contains several serious bugs. It's just not ready (anymore) for any usage other than fixing bugs in it and/or improving it. Hopefully, this will change again soon.

Hello,

Can you help me?
