[Bug libstdc++/35679] Cannot build cross compiler for i686-pc-linux-gnu: configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES
--- Comment #3 from pinskia at gcc dot gnu dot org 2008-03-30 20:19 ---
Using a sysroot or setting --prefix for both the newlib build and the GCC build
is the easiest way of getting a cross build to work.
Anyways here are the options I use to build a cross build for spu:
stage1
binutils: ../src/configure --target=spu-elf --prefix=${HOME}/gcc-spu
gcc: --prefix=${HOME}/gcc-spu --enable-languages=c --with-mpfr=/usr/local
--with-newlib --without-headers --target=spu-elf
newlib: ../src/configure --target=spu-elf --prefix=${HOME}/gcc-spu
stage2
gcc: --prefix=${HOME}/gcc-spu --enable-languages=c,obj-c++
--with-mpfr=/usr/local --with-newlib --target=spu-elf --with-headers
This works without changing any source or headers too.
Thanks,
Andrew Pinski

You can fix it either by providing BSP files (crt*.o, linker script, etc) for your board so that test programs can be linked, or you can disable the AC_LIBTOOL_DLOPEN check in libstc++-v3/configure.ac for newlib targets, as in http://gcc.gnu.org/ml/gcc/2007-11/msg00790.html.
