Yes, you are > going to have to have two versions of your gcc binaries, one with > ld-linux.so.2 and one with ld-linux.so.1, but that should be all. no, there are diffences in symbols between the ld-linux.so.2 coming from libc6 2.3.6 (debian 4.0) and the ld-linux.so.2 coming e.g. from gentoo (http://distfiles.gentoo.org/distfiles/glibc-2.6.1.tar.bz2) but the same thing append also with a newer debian version. This difference may be due to different building flags, patches .... ########## LINUX BOX 1 debian 4.0 libc 2.3.6.ds1-8 ############## root@nowhere:/lib# dpkg -s libc6 Package: libc6 Status: install ok installed ....
