Okay, so I am really stuck here with configuring gcc to use a particular glibc. I have tried to use "-with-sysroot=/blah", but still libstdc++ ends up with symbols for glibc-2.3.2 (I am targeting glibc-2.2.4) which is wrong for my needs. I have even now tried the "--with-headers=/blah --with-libs=/blah" and removing he check for cross compilation, but of course this blows up (yeah, I know, you can not do this). However, it seems to me that this is what I would like, a self contained gcc that links with the sysroot which has the correct glibc (2.2.4). I nm'ed the resulting libstdc++ file created once built and found several symbols for "@GLIBC_2.3". Here is the first config: --enable-languages=c,c++ --disable-nls --disable-multilibs --prefix=/opt/RH72-BUILD-PKGS/gcc-323-t5 --with-sysroot=/opt/RH72-BUILD-PKGS/GLIBC-2.2.4-IMAGE Here is the second config: --enable-languages=c,c++ --disable-nls --disable-multilibs --prefix=/opt/RH72-BUILD-PKGS/gcc-323-t5 --with-sysroot=/opt/RH72-BUILD-PKGS/GLIBC-2.2.4-IMAGE --with-headers=/opt/RH72-BUILD-PKGS/GLIBC-2.2.4-IMAGE/include --with-libs=/opt/RH72-BUILD-PKGS/GLIBC-2.2.4-IMAGE/lib Any help from the gcc experts, I would really appreciate! TIA, Chris
