Re: gcc 3.1 and gdb 5.2?

[Doug Warmke <doug at ikos dot com>]

Guys,

I noticed on the main gcc-3.1 page that the Solaris platform
is not yet making use of dwarf object format.  It's interesting that
you are experiencing the same problem on cygwin as I am experiencing
on Solaris 7 and 8.

We are currently experimenting with the latest available GNU ld
and gdb 5.1.1.  Will keep you posted tomorrow.

Regards,
Doug
