- Subject: undefined virtual table references in 2.12 and later
I have recently encountered a problem when trying to upgrade my
binutils 2.11 to version 2.13.2.1. I even tried the development
version binutils-2.14.90.0.4. From what I can tell, the problem
started happening with version 2.12. The problem is that when I
try and link my executable, I'm getting a bunch of errors like these:
/u/zochd/build2/lib/gcc-lib/i686-pc-linux-gnu/2.95.3/libgcc.a(exception.o):
In function `__check_eh_spec':
/u/zochd/gcc-2.95.3/build2/gcc/../../gcc/cp/exception.cc:307:
undefined reference to `bad_exception type_info function'
/u/zochd/build2/lib/gcc-lib/i686-pc-linux-gnu/2.95.3/libgcc.a(exception.o):
In function `__check_eh_spec':
/u/zochd/gcc-2.95.3/build2/gcc/include/exception:15: undefined
reference to `exception virtual table'
/u/zochd/gcc-2.95.3/build2/gcc/include/exception:22: undefined
reference to `bad_exception virtual table'
I sent a message a few days ago about this and someone responded,
saying that I should try the latest version and that it might be
a problem with the way GNU_VTINHERIT and GNU_VTENTRY relocs are
handled.
>From what I can tell though, in my libgcc.a (I'm using gcc 2.95.3),
the symbols are defined as weak objects, but then undefined several
times also:
00000000 V bad_exception virtual table
00000000 V exception virtual table
U exception virtual table
U exception virtual table
U exception virtual table
I was wondering if anyone could explain to me what is happening,
and how that I might fix it. I'd like to understand what the
proper behavior should be, and what source files within binutils
I could take a look at to try and make it behave as version
2.11 did. Is this a problem with binutils or gcc?
I work in an environment where we need to provide multiple versions
of gcc, but preferably have one version of binutils work for them all.
Thanks,
Donald
