  • 1.  xlc 2.4 and xlclang 2.4.1 do not create DLL export side file

    Posted Fri April 02, 2021 12:29 PM

    In callme.c I have one function:

    int callme(int with)
{
        if (with == 23)
                return 42;
        else
                return -1;
}


    Now I'm trying to compile this using:

    $ xlc -qdll -Wc,xplink -Wl,xplink -qexportall -qrent -qlongname -o callme.dll callme.c
 IEW2689W 4C40 DEFINITION SIDE FILE IS NOT DEFINED.
FSUM3065 The LINKEDIT step ended with return code 4.
$ _


    What am I missing?

    The xlclang frontend does not understand -qdll:

    $ xlclang -qdll -Wc,xplink -Wl,xplink -qexportall -qrent -qlongname -o callme.dll callme.c
FSUM3277 xlclang: The specified option "-qdll" is not supported.

    Got it: it's -Wl,dll instead of -qdll. The documentation is vague on this, so I'm mentioning the resolution here in case others can benefit.
