Since gcc 4.8.0, it defaults to -gdwarf-4. You must explicitly use -gdwarf-2, if you want to debug with the version of gdb in base. Alternatively, use the gdb port, or lldb. -Dimitry signature.asc Description: Message signed with OpenPGP using GPGMail
Re: Dwarf problem with gcc and gdb
The gdb in the base system doesn’t support DWARF4. Use gdb791 or lldb-devel
from ports (I believe gdb791 is probably a better bet on ARM, currently).

Dwarf problem with gcc and gdb
Hi,
Compiled using gcc (FreeBSD Ports Collection) 4.8.5 on arm (Raspberry Pi -
several versions); BSDmakefile attached (make test used).
gdb gives:
GNU gdb 6.1.1 [FreeBSD]
Copyright 2004 Free Software Foundation, Inc.
GDB is free software, covered by the GNU General Public License, and you are
welcome to change it and/or distribute copies of it under certain conditions.
Type "show copying" to see the conditions.
There is absolutely no warranty for GDB. Type "show warranty" for details.
This GDB was configured as "armv6-marcel-freebsd"...Dwarf Error: wrong version
in compilation unit header (is 4, should be 2) [in module /home/ray/mumps/mumps]
I need to fix this to find the *real* problem.
Thanks, Ray
