Hi all,

Here's the output from ldd, of an executable built just recently on Cygwin:

        ntdll.dll => /cygdrive/c/WINDOWS/SYSTEM32/ntdll.dll (0x7ffc339d0000)
        KERNEL32.DLL => /cygdrive/c/WINDOWS/System32/KERNEL32.DLL (0x7ffc31a00000)
        KERNELBASE.dll => /cygdrive/c/WINDOWS/System32/KERNELBASE.dll (0x7ffc30090000)
        cygwin1.dll => /cygdrive/u/2.4.0/release/Cygwin-64/bin/cygwin1.dll (0x180040000)
        cygiconv-2.dll => /usr/bin/cygiconv-2.dll (0x3ec980000)
        cygcom_err-2.dll => /usr/bin/cygcom_err-2.dll (0x3ef750000)
        cygbz2-1.dll => /usr/bin/cygbz2-1.dll (0x3f6a40000)
        cyggcc_s-seh-1.dll => /usr/bin/cyggcc_s-seh-1.dll (0x3ee3a0000)
        cyggssapi_krb5-2.dll => /usr/bin/cyggssapi_krb5-2.dll (0x3eceb0000)
        cygz.dll => /cygdrive/u/2.4.0/release/Cygwin-64/bin/cygz.dll (0x3aba30000)
        cygpcre-1.dll => /usr/bin/cygpcre-1.dll (0x3eb1a0000)
        cygk5crypto-3.dll => /usr/bin/cygk5crypto-3.dll (0x3ec300000)
        cygintl-8.dll => /usr/bin/cygintl-8.dll (0x3ec8d0000)
        cygkrb5support-0.dll => /usr/bin/cygkrb5support-0.dll (0x3ec150000)
        ??? => ??? (0x90000)

My question would be, how to read the last line?  It'd be quite suspicious if ldd is unable to figure out what library (name) is required
(the left side of the =>), but I understand that the library itself might be missing (so it's logical to put "???" on the right side in that case).

Any insight is appreciated.

Thanks,
Anton
