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]

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
