Grex System Problems - Winter 2005/06
| 
Dec 23 04:28 UTC 2005 |
This item is for system problems. If something on Grex isn't working
right (line noise on a modem, weird behavior from a program, etc.),
this is the place to announce it. Except for security holes. If you
find a hole in system security, mail information about it to "staff".

A lot of things have been fixed, tuned or otherwise corrected in
the weeks since the upgrade. Now might be a good time to look
around and see what other systems issues are still outstanding --
broken or not working the same as before the upgrade -- and mention
it here to make certain nothing gets overlooked.

I still can't compile my C++ programs since the upgrade. I compile the
source files like this:
g++ -c -fno-exceptions box.cpp
g++ -c -fno-exceptions line.cpp
g++ -c -fno-exceptions parse.cpp
g++ -c -fno-exceptions token.cpp
and then link them like this:
ld -L/usr/lib/gcc-lib/i386-unknown-openbsd3.8/3.3.5 -lc -lm -lstdc++ -o box
box.o line.o parse.o token.o
The compiles go fine, but the linker has lots of errors of the form:
/usr/lib/libstdc++.so.40.0: undefined reference to `_Unwind_Resume'
/usr/lib/libstdc++.so.40.0: undefined reference to `_Unwind_DeleteException'
and lots more like that. I'm not calling the "Unwind" routines from my
code, so I presume the compiler is putting references in automatically. I
thought maybe if I turned off exceptions that would take care of it, but as
you can see the "-fno-exceptions" flag didn't fix the problem.
So I need to either
a) tell the compiler not to insert those references, or
b) find the libraries that include those Unwind routines and link them in.
Anybody have any ideas?

Try adding -lgcc and see if that fixes it.
