same failure on sparc-linux-gnu (configured the same as in #4267) HEAD 20070329 shows the same behaviour What is the last working version in CVS for PPC and Sparc? I don't have PPC nor Sparc. If you can provide me testcacases for PPC and Sparc I can use with a cross linker, I will try to take a look. I added http://people.ubuntu.com/~doko/tmp/libstd++-v3-gcc-4.1-powerpc-host=i386.tar.bz2 this is a ld configured with --enable-targets=powerpc-linux-gnu,powerpc64-linux-gnu the last binutils I sucessfully checked was 20070210.

I don't see them on Linux/x86-64. for both targets GCC is configured --with-long-double-128, after applying http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25864#c14 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25864#c13 (In reply to comment #7) > for both targets GCC is configured --with-long-double-128, after applying > http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25864#c14 > http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25864#c13 > Those symbols are for glibc. Why do they have libstdc++ version names? I think it is a gcc bug. Please open a gcc bug instead. so has anyone actually reported this to the gcc guys yet and if so where?

It is a gcc bug. The newer linker checks it. Please file a gcc bug report. |
