Don't know exactly, Ive got the same problems here ("no starting address").
Sounds like these linkers dont resolve references from compiler library to
user library?


 KS> and 2. how can something like this be made to work? 

Put a reference to a symbol in main.c in your application.


Example:
/*
--- main.c
--- icc /c main.c
--- lib test.lib -+main;
*/
extern  application();

int MainVar = 0x1234;

main()
{
    return application();
}

/*
--- app.c
--- icc app.c test.lib
*/
extern main();

application()
{
    printf("Something from main.c, &main == 0x%x!\n", main );
    return 0;
}


Successfully tested with C/C++ Tools 2.1 and MS-C 6.00A.
