Hi Everybody,

I am a new owner of DMD CD v8.29 and I am also have a lot of code created in SC 7.21/7.51. If I understand correct, the actual version of IDDE is unable to convert options of projects created in SC (set "Executable" for static libraries, loses defines and so on).

I think in my case the best idea is to create some utility to decide this problem.

Is there any documentation about format of .opt files?

Thanks in advance,

Sergey Gutnikov

I think (I am pretty sure) all you have to do is check the beginning of an SC IDDE
7.51 .opn file and a DM IDDE .opn file. I think there is a signature at the
beginning that you can replace. That should be all there is to it.

I think, this incompatibility can be added to DMC bug list, because all
project files on DMC CD v8.29 have wrong signature in .opn files (and it is very
boring to reenter all necessary flags...).

I have created a small utility to replace a signature. It is for everybody who need it.

<begin of file sc2dmc.c>
/* sc2dmc.c
Written by Sergey Gutnikov, idea by Jan Knepper
------------------------------------------------------------------------
Replace signature in .opn files created with Symantec C++ 7.2/7.5 to Digital Mars C/C++ signature.
------------------------------------------------------------------------
This program have been tested in N memory model only. It was compiled by
SC 7.5 with following flags:
sc -mn -Nc -6 -o+all sc2dmc.c
------------------------------------------------------------------------
To use:
- go to the folder where SC 7.2+ projects are
- enter a command:
> dir /s/b *.opn | sc2dmc.exe
------------------------------------------------------------------------
I think it is a good idea to go to the DMC folder and convert all existing
projects (RTL, MFC 4.2, samples)

It was intended to be resolved in the IDDE. However... so far I have not been able to rebuild the IDDE to executables that do not crash.
