Bug#220624: libc6-dev: breaks builds on 2.4 systems because depending on linux-kernel-headers which contain 2.5 headers

[Alex Tsariounov <alext@fc.hp.com>]

Package: libc6-dev
Version: 2.3.2.ds1-10
Severity: normal


Seems that libc6-dev depends on linux-kernel-headers which contain 2.5
kernel headers.  On a 2.4 system, and perhaps this also applies to
2.5/2.6 systems too, any source that includes <linux/module.h> breaks
with compiler errors.  Attached below is some test code that makes use
of the public interface of query_module().  This builds on pre-ds1-*
libc6-dev systems, but breaks immediately on the current ds1-10 version.

Thanks,
Alex Tsariounov

---8<---- compile this:

#include <stdio.h>
#include <linux/module.h>

main(int argc, char *argv[])
{
    struct module_info mbuf;
    size_t ret;

    if (argc<2) {
        printf("Usage: %s module_name\n", argv[0]);
        exit(1);
    }

    if (query_module(argv[1], QM_INFO, &mbuf, sizeof(mbuf), &ret)) {
        printf("Can't find module %s in kernel\n", argv[1]);
        return 1;
    }
    else {
        printf("Found %s loaded in kernel\n", argv[1]);
    }
    exit(0);
}
