Building the Cross Compiler

What you will need

1. Create a folder to keep the project. Transfer the owner to your current user in order to facilitate the builds. Move to tada folder. All the build will be done from there.

   cd /opt
   sudo mkdir tada
   sudo chwon `whoami` tada
   cd tada

2. Create a download folder in tada/downloads and download the following libraries to it.

   mkdir downloads
   cd downloads

   1. m4. ftp://ftp.gnu.org/gnu/m4/m4-1.4.17.tar.gz
   2. gmp. https://gmplib.org/download/gmp/gmp-5.1.3.tar.bz2
   3. mpfr. ftp://ftp.gnu.org/gnu/mpfr/mpfr-3.1.2.tar.gz
   4. mpc. ftp://ftp.gnu.org/gnu/mpc/mpc-1.0.2.tar.gz
   5. autoconf. ftp://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz
   6. automake. ftp://ftp.gnu.org/gnu/automake/automake-1.9.tar.bz2
   7. binutils. ftp://ftp.gnu.org/gnu/binutils/binutils-2.24.tar.gz
   8. gcc. ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.gz
   9. lex. http://prdownloads.sourceforge.net/flex/flex-2.5.37.tar.gz?download
   10. gnat-gpl

   cd ..

3. Create a folder tada/sources to keep the sources from the libraries. Copy the files from the tada/downloads folder to it, and unpack them.

   mkdir sources
   cp downloads/* sources/
   cd sources

   tar zxf autoconf-2.69.tar.gz
   tar jxf automake-1.9.tar.bz2
   tar zxf binutils-2.24.tar.gz
   tar zxf gcc-4.8.2.tar.gz
   tar jxf gmp-5.1.3.tar.bz2
   tar zxf mpc-1.0.2.tar.gz
   tar zxf mpfr-3.1.2.tar.gz
   tar zxf m4-1.4.17.tar.gz tar zxf flex-2.5.37.tar.gz

   rm *.bz2 *.gz

Step-by-step build

1. Install the generic libraries gmp, mpfr and mpc.

   mkdir gcc-native

   cd m4-1.4.17
   ./configure --prefix=/opt/tada/gcc-native
   make
   make install

   • installation ok

   cd gmp-5.1.3
   ./configure --prefix=/opt/tada/gcc-native
   make
   make install

   • installation ok

   cd ../mpfr-3.1.2
   ./configure --prefix=/opt/tada/gcc-native --with-gmp=/opt/tada/gcc-native make
   make install

   • installation ok

   cd ../mpc-1.0.2
   ./configure --prefix=/opt/tada/gcc-native --with-gmp=/opt/tada/gcc-native
   make
   sudo make install

   • installation ok

   cd ..

2. Install automake, autoconf and binutils

   cd automake-1.9
   ./configure --prefix=/opt/tada/gcc-native
   make
   make install

   • installation ok

   cd ../autoconf-2.69
   ./configure --prefix=/opt/tada/gcc-native
   make
   make install

   • installation ok

   -- maybe not needed cd ../flex-2.5.37 ./configure --prefix=/opt/tada/gcc-native
   make
   make install

   cd ../binutils-2.24
   ./configure --prefix=/opt/tada/gcc-native
   make
   make install

   cd ..

3. Add gcc-native/bin folder to the PATH.

   PATH=/opt/tada/gcc-native/bin:$PATH

4. Build the native gcc compiler.

   cd gcc-native
   ../sources/gcc-4.8.2/configure --prefix=/opt/tada/target --enable-languages=c,ada,c++

   at this point we got:

   blablabla ...
   configure: error: GNAT is required to build ada
   make: *** No targets speficied and no makefile found. Stop.

   so ...
   sudo apt-get install gnat

   and try again...

   cd gcc-native
   ../sources/gcc-4.8.2/configure --prefix=/opt/tada/target --enable-languages=c,ada,c++

   but again:

   blablabla ...
   configure: error: GNAT is required to build ada
   make: *** No targets speficied and no makefile found. Stop.

   wonder why...

---

make
make install
