Build Scripts

The instructions below are for an older version of GCC. For new versions of GCC see the build scripts under the Bugtracker tab for Idea(s)->gnu toolchain build script.

Download GCC

Download and extract the sources from http://ftp.gnu.org/gnu:

   tar zxvf binutils-2.19.1.tar.gz     //changed from 2.19
   tar zxvf gcc-4.3.2.tar.gz

Download GMP (New versions of GCC need this???)

Download ftp://ftp.gnu.org/gnu/gmp/gmp-4.3.2.tar.gz

   Copy to /usr/local/src and uncompress it there.
   tar zxvf gmp-4.3.2.tar.gz

Download MPFR (Multiple-Precision Floating-point with Rounding)

Download and extract from http://www.mpfr.org/mpfr-current/#download:

   unzip mpfr-2.3.2.zip

Build binutils

Note: To install only for one user, use the red PREFIX below and create the /home/username/gnu_mips/tools directory.

   mkdir build-binutils        
   cd build-binutils
   export TARGET=mips-elf
   export PREFIX=/usr/local/$TARGET
   export PREFIX=/home/username/gnu_mips/tools/$TARGET
   export PATH=$PATH:$PREFIX/bin
   ../binutils-2.19.1/configure --target=$TARGET --prefix=$PREFIX
   make
   make install
   cd ..

Build GMP

   mkdir build-gmp
   cd build-gmp
   ../configure --prefix=$PREFIX
   make
   make check
   make install 

Build MPFR

   mkdir build-mpfr
   cd build-mpfr
   ../mpfr-2.3.2/configure -–target=$TARGET -–prefix=$PREFIX --with-gmp=$PREFIX
   make
   make install
   cd ..

Build GCC

   mkdir build-gcc     
   cd build-gcc     
   ../gcc-4.3.2/configure --with-newlib --without-headers --enable-languages="c" \
      --target=$TARGET --prefix=$PREFIX --with-gnu-ld --with-gnu-as --disable-libssp \
      --with-mpfr=$PREFIX --with-gmp=$PREFIX
   make
   make install
   cd ..
