A link error with gcc 3.3.1 is : /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.1/libstdc++.so.5: undefined reference to `_Unwind_Resume_or_Rethrow@GCC_3.3 The solution is to use g++ to link instead of gcc.
when are you getting this error ? what pkg are you emerging ?
with a ebuild that use libstdc++, for exemple xfree, tvtime, gnucash.
I've seen this bug as well, namely in MySQL 4.0.15.
Everyone esperiencing this error, please have a look at this link: http://gcc.gnu.org/ml/gcc-help/2003-07/msg00191.html Check your systems to see if this is the case and report back.
I can test this error with this file (extract from configure shell of gnucash) conftest.c : #include <libofx/libofx.h> int ofx_proc_status_cb(const struct OfxStatusData data) { return 0; } int ofx_proc_account_cb(const struct OfxAccountData data) { return 0; } int ofx_proc_security_cb(const struct OfxSecurityData data) { return 0; } int ofx_proc_transaction_cb(const struct OfxTransactionData data) { return 0; } int ofx_proc_statement_cb(const struct OfxStatementData data) { return 0; } int main() { ofx_proc_file(0, NULL); return 0; } doesn't work with : gcc -o conftest -mcpu=athlon-xp -O3 -pipe conftest.c -lm -lofx -lstdc++ /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.1/libstdc++.so: undefined reference to `_Unwind_Resume_or_Rethrow@GCC_3.3' collect2: ld a retourn

MySQL builds perfectly after fixing the libraries.
Nick: Good to hear that it works. Could you post the commands you used to resolve this as well as the affected symlink?
It's work for me. I have installed gcc form gnu web-site at /opt/gcc-3.1.0/ and I switch to this with gcc-config. the test work. I switch to ebuilded gcc and the the test work. call gcc-config '[1]'
I am recieving this bug too, when trying to emerge app-text/ghostscript-7.07.1. I have tried to use g++ although it doesnt compile. I have gcc 3.3.2-r2. gcc-config -l shows no other versions of gcc. /usr/lib/gcc-lib/i686-pc-linux-gnu/ had a directory 3.3.2 and 3.2.1. I moved the 3.2.1 directory away, which didnt help. ld.so.conf point to the correct lib. Im not sure what else to try. Can i give any more information or try anything else?
I get this error on sablotron with GCC 3.3.2. I also noticed that emerging GCC 3.3.2 left 3.2.3 libs all over /lib (namely libgcc_s-3.2.3.so) and no 3.3.2 libs to replace them or even stand alongside them. libgcc_s is where this reference is defined, so I'm thinking this is the problem. The gcc 3.3.2 ebuild is creating a build environment that isn't sane, and libstdc++ builds are going for the incorrect (old) libs in /lib. The fix: ln -sf /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.2/libgcc_s.so.1 /lib/libgcc_s.so.1 You may also want to delete the libgcc_s-2.3.2 files in /lib if nothing is using them.

Please remove all those symlinks, and run: # ldconfig *** This bug has been marked as a duplicate of 40694 ***
