Hi,

    I need to compile a program using libiberty.a and the function 
getopt_long. When compiling with the flag -liberty my program crash 
because it don't take the right arguments from the command line. But 
without libiberty this part work before.

i made a small program showing that problem, if anyone has an idea ?
i'm using the latest cygwin from the installer ,gcc-3.3.1 and ld 2.15.90 
20040312

thanks

You can find next my source code for the test program and the result i 
have with it.


My test program:

/*begin of argu.c*/
#include <unistd.h>
#include <getopt.h>
#include <ctype.h>
#include <stdio.h>

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

    struct option long_opts[] = {
    {"v", 1, 0, 'v'},
    {"no-v", 0, 0, 'V'},
    {"k", 1, 0, 'k'},
    {"no-k", 0, 0, 'K'},
    {"l", 1, 0, 'l'},
    {"no-l", 0, 0, 'L'},
    {0, 0, 0, 0}
    };
    int c;
    while ((c = getopt_long(argc, argv, "v:Vk:Kl:L:",
        long_opts, NULL)) != EOF) {

    switch(c) {
    case 'v':
        printf("v %s\n",optarg);
        break;
    case 'V':
        printf("V\n");
        break;
    case 'k':
        printf("k %s\n",optarg);
        break;
    case 'K':
        printf("K\n");
        break;
    case 'l':
        printf("l %s\n",optarg);
        break;
    case 'L':
        printf("L\n");
        break;
    case '?':
        printf("other:%c\n",c);
    }
    }
    printf("argc=%d , optind=%d , 
file=%s\n",argc,optind,argc>optind?*(argv+optind):"none");
    return 0;
}
/*end of argu.c*/

when you compile it with : gcc argu.c -o argu.exe it works:
$ ./argu.exe -v abc -K test
v abc
K
argc=5 , optind=4 , file=test

but when you compile it with gcc argu.c -o argu.exe -liberty it gives:
$ ./argu.exe -v abc -K test
v (null)
K
argc=5 , optind=1 , file=-v
