thk you! i downloaded those from the main page (files) :)
Now when i run my app from shell it crashes. Do you know if there's any difference when you run an executable from the shell or from wanderer? (like in morphos with -nostlib? or -noixemul?)

@lellonapoli

If you are using the standard startup code (no -nostdlib or -nostartfiles) then the only difference is the argc and argv values passed to your main function:
Quote:

int main (int argc, char **argv);


If your program is started from WB/Wanderer argc is 0 and argv is a pointer to struct WBStartup as defined in "workbench/startup.h".

If your program is started from Shell argc and argv are set as usual with argc as the number of commandline arguments and argv being a pointer to an array containing the arguments.

#include <workbench/startup.h>
#include <stdio.h>

int main (int argc, char **argv) {
    struct WBStartup *wbsm = NULL;
    int i;
    if (argc == 0) {
        printf("started from WB\n");
        wbsm = (struct WBStartup *)argv;
        for (i = 0; i < wbsm->sm_NumArgs; i++) {
            printf("lock: 0x%08lx name: %s\n",
                wbsm->sm_ArgList[i].wa_Lock,
                wbsm->sm_ArgList[i].wa_Name);
        }
    } else {
        printf("started from Shell\n");
        for (i = 0; i < argc; i++) {
            printf("arg: %s\n", argv[i]);
        }
    }
    return 0;
}

Thank you, useful tip!
I remember this piece of code from 68000 ASM listings
