[Bug bootstrap/35577] New: configure: error: cannot compute suffix of object files

[al dot danial at gmail dot com]

This is on an AMD Opteron system running the 64 bit version of RHEL 4.3
(curious  that it is identified as "unknown-linux-gnu").  I'm building 4.3.0
with GCC 3.4.5 20051201 (Red Hat 3.4.5-2).

My configure command is
  ../gcc-4.3.0/configure --with-gmp=/apps/gmp/4.2.2
--with-mpfr=/apps/mpfr/2.3.0 --prefix=/apps/gcc/4.2.2
--enable-languages=c,c++,fortran,java,objc,obj-c++,treelang

The configure completes successfully.  The error is triggered by
  make bootstrap

The last 20 or so lines of output from make boostrap are:

if [ xinfo = xinfo ]; then \
        makeinfo --split-size=5000000 --split-size=5000000 --split-size=5000000

For what it's worth, the identical problem happens on a 64 bit Solaris 9
system.

You attached the wrong config.log.  We need the one in the
x86_64-unknown-linux-gnu/libgcc subdirectory where configure is failing.

The error in x86_64-unknown-linux-gnu/libgcc/config.log suggests it has trouble
loading libmpfr.so.1.  However the MPFR libraries exist under the
"--with-mpfr=" directory I gave to the configure script:

The fact that they exist there doesn't mean the dynamic loader can find
them unless you tell it.  Have you set LD_LIBRARY_PATH?  Or edited
ld.conf?

Indeed, adding the MPFR and GPM lib directories to LD_LIBRARY_PATH solves the
problem.  For some reason I thought configure would handle this for me since I
gave it --with-gmp and --with-mpfr settings.  Would have been nice if configure
tested for this and given a helpful error.  In any event I'll close this out as
an invalid bug report.

It's the same case when installing any shared library on the system --
you have to inform the dynamic linker of their location (or put them
somewhere it already knows to search) otherwise programs that use that
library can't run.  Configure doesn't really know how you want to handle
this: adding a path to LD_LIBRARY_PATH is but one way; you could also
add the path to ld.so.conf, or relink the libraries with the path
hardcoded (RPATH).  It wouldn't be very prudent to have configure assume
that it should be adding things to LD_LIBRARY_PATH.

The reason the configure checks succeeded is they are checking for
compile time and link time behavior, i.e. they are exercising the link
editor (ld) not the dynamic linker (ld.so).  I suppose it would be
possible for configure to try an additional execute check for sanity if
it's not crosscompiling.  But the best you could do there is report a
problem, as again fixing it is outside of the realm of configure.
