Objet : [fpc-devel] Compiling for libgdb, and using make -j on larger
SPARC
systems
I'm having one of my periodic attempts to check FPC trunk on various
architectures, this was going to be a question about an exception when
trying to link libgdb into 2.6.2 but I find the behaviour has changed so
I mention that for information only. Also for information only, when I
used -j 8 for 2.6.2 there was a message about left-over directories, I
similarly don't get that with trunk (or it's intermittent) so let's
leave it.
So the current situation is this: when building FPC trunk on Debian
Linux on SPARC, everything is fine if I use NOGDB=1. However, if I try
to use libgdb (which has in the past but not particularly recently
worked OK on this system) I get this
make GDB_V603=1 OPT='-O- -gl' all

The obvious first question is: are those references to libgcc
significant, and what file is being looked for? The normal binary
installer hasn't been run on this system since FPC's been built on it
from source since something like 2.0.
Any and all suggestions appreciated.

That looks like it fixes the problem I described earlier, and takes me
back to the one I saw on 2.6.2 (plus possibly some slightly older ones).

At this point: what's actually running, i.e. what command should I apply
gdb to to get a decent backtrace?
