Re: glibc 2.2 vs 2.3 issue back again

[to John]

Glibc considers the PT_INTERP, /lib/ld-linux.so.2, to be an integral part
of glibc.  There are mutual dependencies between ld-linux and glibc.

I wonder whether that is taken care of by my changing /lib/ld-linux.so.2 to /lib2/ldlinux.so.2 everywhere, including the libraries, where the latter path is where I put the loader from Fedora (which is glibc-2.3).

However, you can play by the complete rules, switching the _entire_
glibc package, including ld-linux, for one execve() [command-line process]:

I think I will give this a try - if I see it correctly it basically saves me the LD_LIBRARY_PATH. From what is written at the URL above, it could be that I should copy more libraries from Fedora (even though 'ldd' does not report them).

One question - do I need to change the /lib/ld-linux.so.2 strings in the libraries too, or only in the executables?



[to Roger]

Why can't you just upgrade glibc (or your distribution)? 

Just three reasons (variations on same theme essentially - stability :)

i) upgrading changes/breaks existing things - it takes weeks to reach identical functionality and one often finds in critical moments that something still does not work or is missing and needs immediate install/fixing/workaround. This way there are no surprises - only a single package, Mathematica, does not work, which has moderate priority.

ii) chroot or another linux install could work in principle were it not a notebook where diskspace is limited and there is no free partition

iii) I had bad experience with linux 2.6 + software suspend - it wiped out my root partition the last time I tried (luckily on some other machine)
