You don't say what version of uclibc you are using.
The last time I checked, exception handling on uClibc was
foobar. I am not sure if it is true for the versions you are
using. There may be patches floating around that make things
work (I know I posted some a while back.)
David Daney.
I'm using 0.9.28. I didn't realize uclibc could affect this. Can
you recommend a version where exceptions work?
The problems are in GCC not uClibc.
See: http://gcc.gnu.org/ml/gcc-patches/2006-06/msg00815.html
That was just a prototype patch and it has been a while since I
tried it so I don't know if it is still sufficient.
Basically you need to disable -Dinhibit_libc and have the proper
dwarf2 exception handling code built into libgcc.
In some cases there are problems getting the proper libraries
linked so that dl_iterate_pheader (sp?) is resolved in uClibc.

I was able to resolve this problem by recompiling gcc with "--enable-
sjlj-exceptions --enable-__cxa_atexit" I'm not sure which (or both)
are needed, but they solved my problem.
Thanks to David for pointing me in the right direction,
