-====== Deploy binutils 2.22 ======
+====== Deploy PIC32MX gcc toolchain on Solaris ======
+  * The toolchain **binutils-2.36**, **gcc-10.3.0**, **newlib-1.4** no longer works after upgrade from **SRU62** to **SRU63**, since **libisl** was upgraded from version **15** to version **23**. Re-compilation with libisl 23 fixed the problem.
+  * The toolchain no longer works on s11u4sru37 due to missing /usr/lib/libmpc.so.2 and /usr/lib/libmpfr.so.1 libraries - /opt/mipsel/libexec/gcc/mipsel/4.5.2/cc1 depends on them. Reason being the libraries were upgraded to /usr/lib/limpc.so.3 and /usr/lib/libmpfr.so.4 respectively.
+To workaround the issue, missing libraries were copied from s11u4sru30 where both old as well as new versions of those libraries are available.
+Also, new tool chain has been built based on binutils 2.36, gcc 10.3.0, newlib 4.1.0.
+===== binutils 2.36 =====
+  * start building new one
+<code>
+$ export PATH=/usr/gnu/bin:$PATH
+$ mkdir ~/projects/gcc-mips-10.3.0/
+$ cd ~/projects/gcc-mips-10.3.0/
+$ wget http://ftp.gnu.org/gnu/binutils/binutils-2.36.tar.gz -O /tmp/binutils-2.36.tar.gz
+$ tar xvpf /tmp/binutils-2.36.tar.gz
+$ mkdir build-binutils-el-2.36
+$ cd build-binutils-el-2.36
+$ ../binutils-2.36/configure --target=mipsel --prefix=/opt/mipsel
+$ make
+$ sudo make install
+</code>
+===== binutils 2.37 =====
+  * man pages were not built - instead use binutils 2.36
+  * save existing toolchain and prepare for building new one
+<code>
+$ mv ~/projects/gcc-mips/ ~/projects/gcc-mips-ok/
+# mv /data/apps-local/mipsel /data/apps-local/mipsel-ok
+# mkdir /data/apps-local/mipsel
+</code>
+  * start building new one
+<code>
+$ export PATH=/usr/gnu/bin:$PATH
+$ mkdir ~/projects/gcc-mips/
+$ cd ~/projects/gcc-mips/
+$ wget http://ftp.gnu.org/gnu/binutils/binutils-2.37.tar.gz -O /tmp/binutils-2.37.tar.gz
+$ tar xvpf /tmp/binutils-2.37.tar.gz
+$ mkdir build-binutils-el
+$ cd build-binutils-el
+$ ../binutils-2.37/configure --target=mipsel --prefix=/opt/mipsel
+$ make
+$ sudo make install
+</code>
+===== gcc 10.3.0 with newlib 4.1.0 =====
+  * prepare working area
+<code>
+$ cd ~/projects/gcc-mips-10.3.0/
+$ mkdir build-gcc-el-10.3.0
+$ mkdir build-newlib-el-4.1.0
+</code>
+  * download and unpack
+<code>
+$ wget http://ftp.gnu.org/gnu/gcc/gcc-10.3.0/gcc-10.3.0.tar.gz -O /tmp/gcc-10.3.0.tar.gz
+$ tar xvpf /tmp/gcc-10.3.0.tar.gz
+$ wget ftp://sourceware.org/pub/newlib/newlib-4.1.0.tar.gz -O /tmp/newlib-4.1.0.tar.gz
+$ tar xvpf /tmp/newlib-4.1.0.tar.gz
+</code>
+  * build and install (tools will be installed into /opt/mipsel/ directory). Building gcc with newlib is done in three steps.
+===== Stage 1 - build bootstrap gcc =====
+<code>
+$ cd build-gcc-el-10.3.0
+$ ../gcc-10.3.0/configure --target=mipsel --prefix=/opt/mipsel-10.3.0 --without-headers --with-gnu-as --with-gnu-ld --with-newlib --enable-languages=c --with-local-prefix=/opt/mipsel --with-native-system-header-dir=/opt/mipsel/include/ --disable-nls --disable-shared  --enable-multilib --disable-decimal-float -disable-threads --disable-libmudflap --disable-libssp --disable-libgomp --disable-libquadmath
+$ make
+$ sudo make install
+</code>
+  * **--enable-multilib** - builds several variants of libraries (big-endian, little-endian hard-float and soft-float). Default is little-endian hard-float.
+<code>
+$ /opt/mipsel-10.3.0/bin/mipsel-gcc -print-multi-lib
+.;
+soft-float;@msoft-float
+eb;@EB
+soft-float/eb;@msoft-float@EB
+$
+</code>
+===== Stage 2 - deploy newlib =====
+  * newlib requires mips-cc
+<code>
+# cd /opt/mipsel-10.3.0/bin
+# ln -s mipsel-gcc mipsel-cc
+</code>
+  * build and install
+<code>$ export PATH=/opt/mipsel-10.3.0/bin:$PATH
+$ cd ~/projects/gcc-mips-10.3.0/build-newlib-el-4.1.0
+$ ../newlib-4.1.0/configure --target=mipsel --prefix=/opt/mipsel-10.3.0
+$ make ; echo $?
