+Work-in-progress. Ignore for now.

+

+Some build scripts for GCC toolchains. Notably the

+Cortex CPUs require the very latest GCC version 4.3.x.

+

+These are to be considered working notes for testers and

+not a definitive source on how to build GCC toolchains.

+

+1. get latest binutils, gcc, gdb and newlib

+

+2. unzip source to src folder

+

+2. fix libstc++/configure.ac

+

+

+That works. After replacing AC_LIBTOOL_DLOPEN with

+

+  if test "x${with_newlib}" != "xyes"; then

+    AC_LIBTOOL_DLOPEN

+  fi

+

+and running autoconf I was able to build six different newlib targets.

+

+http://gcc.gnu.org/ml/gcc/2008-03/msg00611.html

+

+3. place newlib and libgloss into src/gcc

+

+4. run cygwin.sh or linux.sh

+

+

+Resources:

+Results:

+Build results from Zylin AS following the instructions above:
