Hmmm, I tried gcc-4.1.2 for 'pdp11-bsd2.11' target and that seemed to
succeed. Maybe gcc-4.3.2 is
broken for PDP11 :( Support dropped (obsolete) in 4.3.3...
Build options were:
--target=pdp11 \
--enable-languages="c" \
--with-system-zlib \
--disable-nls \
--with-libiconv-prefix="/usr/local" \
--without-included_gettext \
--with-newlib \
--with-dwarf2 \
--disable-shared \
--with-gmp="/usr/local" \
--with-mpfr="/usr/local" \
You must like things being as complicate as possible... My simple
configure was :
../configure --build=i686-linux-gnu --host=i686-linux-gnu \
--target=pdp11-bsd2.11 --enable-languages=c,c++ --disable-shared \
--with-gxx-include-dir=/usr/local/include/c++/4.1.2 \
--enable-version-specific-runtime-libs
When I hadn't those 2.11BSD headers and libraries my build stopped in
libstdc++-v3 :
