I do not kmow anout the error messages but here are some tips I have found.
The version of gcc installed in the system should be same or very close to the
source code. So install the newest package available.
I'm using the exact sources of GCC from the Ubuntu archives (4.7.2), and have
applied the necessary Debian patches.
The full build process first makes a compiler and then tries to compile itself
again with this new compiler. For me this seems to fail more often than not. For
cross compilers this is not possible at all. The option --disable-bootstrap
omits this last stage.
Ahhh, I'd forgotten about --disable-bootstrap: adding that to the configure
instructions seems to solve all the problems. I've now successfully built and
installed GDC 4.7, and the -j option does not disturb the build.
Just for reference, my successful configuration was:
../gcc-4.7-4.7.2/src/configure --enable-languages=d --disable-multilib
--disable-libgomp --disable-libmudflap --disable-libquadmath
--disable-libquadmath-support --disable-bootstrap --enable-checking=release
I'd first done a successful build with --disable-lto and without the
--enable-checking option, so having done that, I thought I'd give these updated
options a go. Works fine!
Thanks so much to everyone for all the advice and patience in helping me get a
successful build.
Best wishes,
