%general-entities; ]> EGLIBC Tell EGLIBC to install its libraries into /lib: echo "slibdir=/lib" >> configparms CFLAGS="-O2" \ ../eglibc-&eglibc-version;/configure --prefix=/usr \ --disable-profile --enable-kernel=2.6.32 \ --libexecdir=/usr/lib/eglibc --libdir=/usr/lib \ --enable-obsolete-rpc --libexecdir=/usr/lib/eglibc This changes the location of the pt_chown program from its default of /usr/libexec to /usr/lib/eglibc. The install will finish by checking that everything is correctly installed. Unfortunately, it will test for a multilib installation. On x86_64 Pure64 this means it will try to test the non-existent 32-bit loader which has a different name from the 64-bit loader (unlike on other 64-bit architectures). We fool it by creating a symlink to the real loader. ln -sv &eglibc-ld-name; /lib/ld-linux.so.2 Now we can remove this symlink. We also need to correct the /usr/bin/ldd script - if you look at this, you will see it references not only the 32-bit linker, but also /lib64 where it thinks the 64-bit linker is. The following sed will correct this: rm -v /lib/ld-linux.so.2 cp -v /usr/bin/ldd{,.bak} sed '/RTLDLIST/s%/ld-linux.so.2 /lib64%%' /usr/bin/ldd.bak >/usr/bin/ldd Check the script to make sure the sed worked correctly, then delete the backup. rm -v /usr/bin/ldd.bak The stubs.h header installed by EGLIBC looks for stubs-32.h and stubs-64.h. This configuration of EGLIBC only generates stubs-64.h. Fix this with the following: mv -v /usr/include/gnu/stubs{-64,}.h /etc/ld.so.conf By default, the dynamic loader (/lib/ld-linux-x86-64.so.2) searches through /lib and /usr/lib for dynamic libraries that are needed by programs as they are run. However, if there are libraries in directories other than /lib and /usr/lib, these need to be added to the /etc/ld.so.conf file in order for the dynamic loader to find them. Two directories that are commonly known to contain additional libraries are /usr/local/lib and /opt/lib, so add those directories to the dynamic loader's search path.
