Hello again, Need some help still. I am trying to configure gcc to pull headers out of a glibc2.2.4 (my running system is on 2.3.2). I have configured gcc as such: ../configure --enable-languages=c,c++ --disable-multilibs --disable-nls --with-sysroot=/opt/RH72-BUILD-PKGS/GLIBC-2.2.4-IMAGE --prefix=/opt/RH72-BUILD-PKGS/gcc323 Everything built correctly. However, when I try to compile an executable I get this: /opt/RH72-BUILD-PKGS/gcc323/lib/gcc-lib/i686-pc-linux-gnu/3.2.3/../../../libstdc++.so: undefined reference to `__strftime_l@xxxxxxxxx' /opt/RH72-BUILD-PKGS/gcc323/lib/gcc-lib/i686-pc-linux-gnu/3.2.3/../../../libstdc++.so: undefined reference to `__wcsftime_l@xxxxxxxxx' /opt/RH72-BUILD-PKGS/gcc323/lib/gcc-lib/i686-pc-linux-gnu/3.2.3/../../../libstdc++.so: undefined reference to `__uselocale@xxxxxxxxx' collect2: ld returned 1 exit status So it looks like the libstc++ is linked against glibc 2.3.2 (the system libraries). What am I doing wrong? I want to be able to compile the executable with glibc2.2.4. TIA, Chris
