The gcc dev's caught you out ;-) I think that what you have
attached is the top-level config.log. That runs before 'make', but
then make runs configure in various directories. In this case, it
seems to have failed in the libgcc directory.
The attached file shows error(s) which are normal. For example,
configure creates a tiny test program to see if libisl exists and
the long output shows an apparent error, but the screen output from
the initial configure would have been:
checking for objdir... .libs
checking for version 0.10 of ISL... no
checking for version 0.11 of ISL... no
checking for version 0.12 of ISL... no
*** This configuration is not supported in the following subdirectories:
target-libquadmath gnattools target-libada target-libgfortran
target-libgo target-libffi target-libbacktrace target-zlib
target-libjava target-libobjc target-libgomp target-libcilkrts
target-libatomic target-libitm target-libstdc++-v3
target-libsanitizer target-libvtv target-libssp target-boehm-gc
(Any other directories should still work fine.)
So, what you now need to do is check the newest config.log (in
libgcc, I think), then search for 'cannot compute suffix of object
files:' e.g. in view or less, use the command
/cannot\ compute
and then look at the lines above, probably a screen or two earlier.
You should see the 'checking for suffix' message, a program
fragment, and a more-detailed error, probably from gcc. That error
message should identify the problem.
Ken you were correct that the config.log I need is in libgcc and that
the error is there as well. Here is the snippet I believe that causes a
problem. Unfortunately I can't figure out what it means. Just in case
I'm also posting the contents of
/mnt/lfs/sources/gcc-build/x86_64-lfs-linux-gnu/libgcc/config.log. Any
help is appreciated.
If you hit for
"configure: error: cannot compute suffix of object files: cannot compile"
on google, it finds many references to GMP/MPFR/MPC
Make sure you understood the note in the book above the commands
that extract those tarballs.
