Build error on Solaris 10 (libiconv messages)

[Dr. David Kirkby]

I'm trying to build gcc 4.4.0 on a sun Blade 2000 running Solaris 10 
update 6.

  $ uname -a
SunOS kestrel 5.10 Generic_139555-08 sun4u sparc SUNW,Sun-Blade-1000 Solaris

The compiler I'm tyring to use to build gcc 4.4.0 is gcc 3.4.3 which is 
installed in /usr/sfw/bin.

drkirkby@kestrel:[~] $ /usr/sfw/bin/gcc -v
Reading specs from /usr/sfw/lib/gcc/sparc-sun-solaris2.10/3.4.3/specs
Configured with: 
/sfw10/builds/build/sfw10-patch/usr/src/cmd/gcc/gcc-3.4.3/configure 
--prefix=/usr/sfw --with-as=/usr/ccs/bin/as --without-gnu-as 
--with-ld=/usr/ccs/bin/ld --without-gnu-ld --enable-languages=c,c++ 
--enable-shared
Thread model: posix
gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath)


I particularly want to use both the Sun linker and assembler, not the 
GNU ones, so linked as below.

   $ ../gcc-4.4.0/configure CC=/usr/sfw/bin/gcc 
--prefix=/export/home/drkirkby/install-gcc-4.4.0-Sun-as-ld 
--with-as=/usr/ccs/bin/as --without-gnu-as --with-ld=/usr/ccs/bin/ld 
--without-gnu-ld --enable-languages=c,c++,fortran 
--with-mpfr-include=/export/home/drkirkby/install-mpfr-2.3.1/include 
--with-mpfr-lib=/export/home/drkirkby/install-mpfr-2.3.1/lib 
--with-gmp-include=/export/home/drkirkby/install-gmp-4.3.1/include 
--with-gmp-lib=/export/home/drkirkby/install-gmp-4.3.1/lib --disable-nls

(I've tried both with and without the --disable-nls, but it made no 
difference).

I get the following errors, which mention libiconv. As far as I can 
tell, having that is not a prequisite (or at least it is not listed as 
one at

Any ideas how I might solve this?
