The problem is that these missing functions come from a new separate
library, libgcc_eh.a in gcc-lib.I can't seem to correctly specify that
library's inclusion on the command line. Instead the only way to get
it included is to edit synth.ld so that's probably what's required.
But why haven't people noticed this before? Versions of GCC 3.x before
GCC 3.2.1 wouldn't work unless people were going back as far as gcc 2.9x.
With RedHat 9.0 (gcc-3.2.2), there are some problems with libgcc_eh.a
included. Testsuite for linux-synthetic target breaks with:
make: Leaving directory `/home/dejan/tmp/synth_build/infra/current'
In function `_Unwind_Find_FDE':
make: Leaving directory `/home/dejan/tmp/synth_build'
: undefined reference to `dl_iterate_phdr'
I was worried something like this might happen. We can do an explicit
check for _GNUC_PATCHLEVEL_ but it would be nice to know if this is maybe
something specific with the RH9 3.2.2 or not. Or 3.2.3 or GCC CVS for that
matter. Anyone got those native tools and willing to try it quickly?
I'm not running RH9 myself I'm afraid.
