Trouble building Apple gdb on Linux


Hi,

I'm building Apple's gdb-2.9.2 on Linux by following the instructions in "Useing non-Darwin systems as Darwin/Mac OS X kernel debugging hosts":

http://pknet.com/~joe/apple-cross-gdb.html

I'm trying to build Apple's gdb on my Debian sarge PC so I can debug a kernel extension (device driver) on my Mac OS X Mac over ethernet. I need to do this because the ethernet port is busted on my other Mac and I'm not able to get it repaired right away.

The page advises one not to run ./configure in the main source directory, but to configure and build each library one at a time and then to build gdb. This goes well most of the way but when building gdb, from Apple's gdb-292 source with some patches applied, I get these errors:

gcc -c -g -O2 -DTARGET_POWERPC -I./macosx -I. -I. -I./config -DLOCALEDIR="\"/usr/local/share/locale\"" -DHAVE_CONFIG_H -I./../include/opcode -I./../readline/.. -I../bfd -I./../bfd -I./../include -I../intl -I./../intl -DMI_OUT=1 -Wimplicit -Wreturn-type -Wcomment -Wtrigraphs -Wformat -Wparentheses -Wpointer-arith -Wuninitialized dwarf2read.c

dwarf2read.c:2464: error: assignment of read-only member `nfn_fields_total'
make: *** [dwarf2read.o] Error 1


Looking at the source in question, it looks like it's doing something complex via a bunch of macros that I don't understand.

Can anyone help me out here?

I will go ahead and try to figure it out but I thought someone might be able to help.

Thanks!
