Updated script that builds RTEMS5 toolchain.

OAR/contrib/build.rtems.5.sh

+#!/bin/bash
+#
+# This script builds the RTEMS/SPARC cross-compiler and the
+# Leon2/Leon3/NGMP BSPs.
+#
+# To have a reproducible setup, it would be prudent if you
+# executed this script under a Debian stretch chroot,
+# bootstrapped via the following:
+#
+#     mkdir /opt/stretch-chroot
+#     debootstrap stretch /opt/stretch-chroot
+#     mount -t proc none /opt/stretch-chroot/proc/
+#     mount -t sysfs none /opt/stretch-chroot/sys/
+#     mount -o bind /dev /opt/stretch-chroot/dev/
+#     mount -o bind /dev/pts /opt/stretch-chroot/dev/pts/
+#     chroot /opt/stretch-chroot
+#     apt-get update
+#     apt-get install flex bison make texinfo binutils gcc g++ gdb unzip git python2.7-dev pax libncurses5-dev
+#
+# Then chroot inside it and run this script:
+#
+#     chroot /opt/stretch-chroot
+#     /path/to/build.rtems.MORA.sh
+
+
+# Stop on any error
+set -e
