Hi,
I have actually have the same error of :-
configure:2341:17: error: gmp.h: No such file or directory
when I tried compiling gcc-4.2.1 with a separate BUILD folder apart
from its
source file folder.
I did ../configure --prefix=/local/gcc/gcc-4.2.1/
but when I do a make bootstrap, the above error is displayed in
config.log.
And i just coudl not proceed. Please advise what I could do.
Thanks.
Rgrds,
Jason

Cool! :-)
Considering that binutils 2.18 just came out *yesterday*,
and the other
distro maintainers (myself and Joerg Wunsch) haven't had a
chance to try it
out yet, you would be going into new territory. A slightly
safer bet is to
use binutils 2.17 with gcc 4.2.1. That combination has had
a bit more
traffic.
binutils 2.18 compiled and installed without fuss, so I'm pretty
sure
that's not the problem.
The most common build error is configuring gcc in its own
source directory.
But you're following the directions in the avr-libc user
manual, so I assume
that you have avoided doing this? Was your configuration
successful?
Yes, and I think so.
Can you attach the output from configure and from make so
we can have more
context?
Here it is; I'm installing into /usr/local, so I don't set $PREFIX.
NOte that I use gmake instead of make. Take a deep breath 'cause
there's lots of it! :-)

GCC now depends on the GMP and MPFR packages.
<http://gmplib.org/>
<http://www.mpfr.org/>
Building and installation of these libraries is pretty easy. MPFR
depends
on
GMP, so build GMP first:
./configure --disabled-shared 2>&1 | tee gmp-configure.log
make 2>&1 | tee gmp-make.log
make check 2>&1 | tee gmp-make-check.log
make install 2>&1 | tee gmp-make-install.log
Then MPFR:
./configure --with-gmp=/usr/local --disable-shared 2>&1 | tee
mpfr-configure.log
make 2>&1 | tee mpfr-make.log
make check 2>&1 | tee mpfr-make-check.log
make install 2>&1 | tee mpfr-make-install.log
Then you have to tell GCC where these libraries reside, during the
configure
process:
../gcc-$version/configure \
--prefix=$installdir \
--target=$target \
--enable-languages=c,c++,objc \
--with-dwarf2 \
--enable-win32-registry=WinAVR-$release \
--disable-nls \
--with-gmp=/usr/local \
--with-mpfr=/usr/local \
--enable-doc \
--disable-shared \
2>&1 | tee $package-configure.log
(Ignore the win32/WinAVR flag. And don't build the objc front-end
without
the patch I have.)
See if this gets you any farther.
HTH,
Eric Weddington
