Subject: Problem while Crosscompiling Ksymoops

Hi,
I am trying to cross compile ksymoops-2.4.9 for Strong ARM.
But i
am getting a segmentation Fault. The error messages is as below.
Can anybody tell me what should be given for DEF_MAP, since in
the
target machine there is no System.map file.

Can anybody give some idea on this.

Thanks and regards
Jairam

The command line for the final link is wrong. It should contain

-Wl,-Bstatic -lbfd -liberty -Wl,-Bdynamic -o ksymoops

You replaced '-Wl' with '-arm-linux-ld', ld did not understand that and
got a segmentation fault trying to handle the unknown parameter.
Correct your command line, and log a problem against binutils that it
cannot cope with unexpected options.

Without a system map, you are not going to get much of a decode. But
if that is what you want, add 'DEFMAP=' to the make command line.
