Deploy PIC32MX gcc toolchain on Ubuntu 24.04.2 LTS
- tool chain has been built based on binutils 2.36, gcc 10.3.0, newlib 4.1.0.
install prerequisites
$ sudo apt install libgmp3-dev libmpfr-dev libmpc-dev
binutils 2.36
$ mkdir -p ~/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 ~/Downloads/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-10.3.0 $ make $ sudo make install
gcc 10.3.0 with newlib 4.1.0
- prepare working area
$ cd ~/projects/gcc-mips-10.3.0/ $ mkdir build-gcc-el-10.3.0 $ mkdir build-newlib-el-4.1.0
- download and unpack
$ 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
- build and install (tools will be installed into /opt/mipsel-10.3.0/ directory). Building gcc with newlib is done in three steps.
Stage 1 - build bootstrap gcc
$ 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-10.3.0 --with-native-system-header-dir=/opt/mipsel-10.3.0/include/ --disable-nls --disable-shared --enable-multilib --disable-decimal-float -disable-threads --disable-libmudflap --disable-libssp --disable-libgomp --disable-libquadmath $ make $ sudo make install
- –enable-multilib - builds several variants of libraries (big-endian, little-endian hard-float and soft-float). Default is little-endian hard-float.
$ /opt/mipsel-10.3.0/bin/mipsel-gcc -print-multi-lib .; soft-float;@msoft-float eb;@EB soft-float/eb;@msoft-float@EB $
Stage 2 - deploy newlib
- newlib requires mips-cc
# cd /opt/mipsel-10.3.0/bin # ln -s mipsel-gcc mipsel-cc
- build and install
$ 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 $?
