I have the need to add -rpath <egcs-prefix-dir>/lib everytime the C/C++
frontends invoke the link/loader behind the scene -rpath <egcs-prefix-dir>/lib.
I've checked the FAQ http://egcs.cygnus.com/faq.html#rpath but this does not
help.
The solution to add -rpath to every is error prone and I can't use
LD_LIBRARY_PATH because this would confuse other C++ apps because
the the shared C++ libs are not binary compatible.
They are not binary compatible because I can't use GNU as (not supported
on Digital Unix) and in order too
prevent 'Line too long' errors of the Digital Unix assembler I had to enable
flag_do_squangling = 1 in gcc/cp/decl2.c as described in
http://egcs.cygnus.com/faq.html#squangle
One solution might be to put a ld wrapper into <egcs-prefix-dir>/bin
that add -rpath ... to the arguments before it invokes the real ld. But
Hope that there is a way to specify it during configure/bootstrap
time so I don't have to cheat.
A second solution would be to not use shared libs but this would be
really pity :-)
Thanks in advance for any advise,
Achim

You can modify the specs file (installed in gcc-lib/*/*) so as to add
whatever options you want to the link command. You may do that in the
*link or *lib spec, for example. IMO, this tip should be added to the
FAQ.

You don't have to configure the compiler differently. Just modify the
file 'specs' found in the same directory where 'cc1' is installed.

Would you mind adding it? ;-) (Consider it approved, just send the patch
to egcs-patches after installation.)
Thanks!

Ok, I'm installing the attached patch, after updating the `Last
modified' date.
