Hi there,
Thanks for the reply.
The simple1 which worked is a modified version, in which I changed to
connect to a remote server which does exist. Since I cannot run a local
server, the original simple1 always crashes. And I am trying to find out
why exception handling is not working here. Suppose the "cannot connect"
exception should be caught instead of crash with coredump?
Also I tried the custom.pl patch (by Warren Young?), it still fails at
examples/custom[1-4].cc. However with custom.pl which Bryan posted Feb
10 with Jim Peden fix, I can compile all the example code smoothly.
So with Bryan's 3.3 patch and custom.pl, I can compile the whole package
smoothly. I also tried ./configure --enable-exception.
However, exception handling still not work for me.
I just hand-build simple1.cc and from gdb I saw the following
stack-trace:
Program terminated with signal 6, Aborted.
...
#0 0xff19bb54 in _libc_kill () from /usr/lib/libc.so.1
(gdb) bt
#0 0xff19bb54 in _libc_kill () from /usr/lib/libc.so.1
#1 0xff1357c4 in abort () from /usr/lib/libc.so.1
#2 0xff261acc in __cxxabiv1::__terminate(void (*)()) (
handler=0xff1356bc <abort>)
at ../../../../libstdc++-v3/libsupc++/eh_terminate.cc:47
#3 0xff261b04 in std::terminate() ()
at ../../../../libstdc++-v3/libsupc++/eh_terminate.cc:57
Could you give me any hints what is wrong?
Thanks a lot!
Yigong

You said before that simple worked for you. What changed ????
To build it for debugging you have to compile it manually.
Also, you can not expect to have things running if patching did not
succeed.
So go back and try to patch it withoum problems. You will have to fix
things manually for the failed patches.
