Link C++ - SKILL

Yann00

hi,

 

Could someone explain to me how to make a link between C++ and SKILL?

I have to develop a program in SKILL. But I do some text treatment in C++. So how I can load my SKILL program, and then lunch my C++ program? I have, in the SKILL program, to have a position with text file from C++.

Ask me if you want more details.

Best regards

  • Yes I do.

    What did you write in system("??")?

    Does it create a file text "Centre_Cartouche.txt"? Because I give you the file Centre_Cartouche.txt just for you to have a look wath it seems like.

    (brd.txt,   sym.txt ) is the two files read by the C++ at the beginning. Centre_Cartouche.txt will be create after treatment on this two files. So  Centre_Cartouche.txt is my output. 

  • Hi Yann00,

    As fxffxf wrote, system("program arg1 arg2...") should to work.

    One thing which *might* be going wrong is that if you are working under
    Windows, reverse solidus (\) characters have to be doubled in literal
    strings, as they clash with the SKILL escape mechanism:

    system("e:\\work\\program.exe arg1 arg2...")

    Another thing to watch out for is spaces in the path to the binary; I'm
    not even sure about the proper quoting mechanism under Windows… this
    *might* work, but I'd double check the docs for cmd.exe:

    system("\"c:\\Program Files\\My\\Program.exe\" arg1 arg2...")

    (And similarly for the arguments.)

    Another solution, which offers more control—but suffers from the same
    quoting madness—would be to use the ipc* family of functions
    (ipcBeginProcess, etc.). I have put together a small example at:

    s.crosstwine.com/spb/d2692740

    and you will find a complete package attached to this message (tested
    under Linux).

    Hope this helps,
    Damien

  • So it seems attachments to email replies get eaten by the system.

    Trying again, using the web interface; I have also uploaded an unpacked version to:

     http://crosstwine.com/misc/letters/2013/01/16/SKILL-C++-Interaction/c-delegate/ 

    c-delegate-ad93a5f3.zip

  • I tried your example and it seems to be ok.

    But there is something wrong when I try to do the same for me...  (every time (: )

    So I won to create my DLL program. I put files there and it works, it creates my Centre_Cartouche.txt when I Test my DLL.

    I tried to import it in my skill program. And strange, ... It doesn't work!

    I read the allegro pdf on that but I have some problems to identify my problem.

    Did someone already load a dll on his skill program?

  • Like in C, Skill treats the backslash character (\) as special. If spawning a program via the Skill "system" call. You should try using UNIX style path seperates (/) instead of Windows style. If using backslashes depending upon what you do in creating the string you may need to escape the baclslash (e..g use 2 backslashes to get 1).
