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.

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.

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 ?

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);
}
