Have that piece of code:


int launch_command(const char *command) {

#ifdef USE_WIN

       ShellExecute(NULL,"open",command,NULL,NULL,SW_SHOWNORMAL);

       return (0);

#elif defined(__amigaos4__)

       BPTR in = IDOS->DupFileHandle(IDOS->Input()); 

       BPTR out = IDOS->DupFileHandle(IDOS->Output()); 



       return IDOS->SystemTags(command,

                 SYS_Asynch,TRUE, 

                 SYS_Input,in, 

                 SYS_Output,out, 

                 TAG_DONE);

#else

    return system(command);

#endif

}

So, when i want to run external command (such as odyssey for example), then, when i run main binary from the shell all works fine and odyssey runs fine. But when i run main binary from the icon (workbench type), then it says "odyssey: Unknown command"

Should i adapt code somehow so it will works and when i run it from icon workbench type too ?

The problem is that Workbench is not a CLI process so that is no path to inherit from it. (or if there is it's the absolute minimum default of C: CurentDIR:

The only solution I ever found was to run the program from shell.

Quite a regular

Does it work if you use an absolute path? You could temporarily change the current directory to PROGDIR: (GetProgramDir() gives you the lock) and back. Or maybe setting NP_HomeDir to the PROGDIR lock could help.

This is just like television, only you can see much further.

I don't think it relates to your problem but I think your code should check the return value for SystemTags() and close the 'in' and 'out' filehandles if SystemTags() fails.

I probably can just try it as "appdir:odyssey" for example , that may works and from icon and from shell ?

Just popping in

Hmmm. Would appdir:odyssey work if odyssey had not yet been run a first time?

Maybe there is a way to add from the code some kind of copy of pathes/etc which holds when one run it as CLI process ?

From AutoRun commodity:


static void execute_command(CONST_STRPTR command) {

    struct Library *workbenchbase;

    struct WorkbenchIFace *iworkbench;

    BPTR path_list = ZERO;

    BPTR input_file = ZERO;

    BPTR output_file = ZERO;

    int32 error = -1;



    workbenchbase = IExec->OpenLibrary("workbench.library", 53);

    iworkbench = (struct WorkbenchIFace *)IExec->GetInterface(workbenchbase, "main", 1, NULL);



    if (iworkbench != NULL) {

        iworkbench->WorkbenchControl(NULL,

            WBCTRLA_DuplicateSearchPath, &path_list,

            TAG_END);

    }



    input_file = IDOS->Open("NIL:", MODE_OLDFILE);

    output_file = IDOS->Open("NIL:", MODE_OLDFILE);



    if (input_file && output_file) {

        error = IDOS->SystemTags(command,

            NP_Name,    "AutoRun Script",

            NP_Path,    path_list,

            SYS_Asynch, TRUE,

            SYS_Input,  input_file,

            SYS_Output, output_file,

            SYS_Error,  ZERO,

            TAG_END);

    }



    if (error) {

        IDOS->Close(input_file);

        IDOS->Close(output_file);

    }



    if (error && iworkbench != NULL) {

        iworkbench->WorkbenchControl(NULL,

            WBCTRLA_FreeSearchPath, path_list,

            TAG_END);

    }



    IExec->DropInterface((struct Interface *)iworkbench);

    IExec->CloseLibrary(workbenchbase);

}
