|
|
These are instructions for creating a MIPS cross-compiler toolchain based on
|
| 5 |
|
|
GCC 4.7.1, Binutils 2.21, and Newlib 1.20.0.

Procedure
|
| 20 |
|
|
---------
|
| 21 |
|
|
|
| 22 |
|
|
The following assumes you are using Bash or Bash-like shell. This procedure
|
| 23 |
|
|
has been tested in Linux environments as well as Windows under Cygwin. If you
|
| 24 |
|
|
are using Cygwin, you must be running on a 32-bit Windows OS or VM.
|
| 25 |
|
|
Limitations with WoW in 64-bit Windows prevents enough stack/heap space from
|
| 26 |
|
|
being allocated. Once the toolchain is compiled it may be used under 64-bit
|
| 27 |
|
|
Windows.
|
| 28 |
|

|
|
1. Set environment variables:
|
| 31 |
|
|
export TARGET=mips-elf
|
| 32 |
|
|
export PREFIX=[some directory]/gnu_mips/crosstools
|
| 33 |
|
|
export PATH=$PATH:$PREFIX/bin
|
| 34 |
|
|
|
| 35 |
|
|
1.5. If you're on 32-bit Windows using Cygwin:
|
| 36 |
|
|
export CFLAGS="-Wl,--heap,200000000,--stack,8000000"
|
| 37 |
|
|
|
| 38 |
|
|
2. Unpack everything:
|
| 39 |
|
|
bzip2 -dc binutils-2.21.tar.bz2 | tar xf -
|
| 40 |
|
|
bzip2 -dc gcc-4.7.1.tar.bz2 | tar xf -
|
| 41 |
|
|
bzip2 -dc mpfr-3.0.1.tar.bz2 | tar xf -
|
| 42 |
|
|
bzip2 -dc gmp-5.0.5.tar.bz2 | tar xf -
|
| 43 |
|
|
gzip -dc mpc-0.9.tar.gz | tar xf -
|
| 44 |
|
|
gzip -dc newlib-1.20.0.tar.gz | tar xf -
|
| 45 |
|
|
|
| 46 |
|
|
3. Move (or symlink) GCC dependency packages
|
| 47 |
|
|
mv gmp-5.0.5 gcc-4.7.1/gmp
|
| 48 |
|
|
mv mpc-0.9 gcc-4.7.1/mpc
|
| 49 |
|
|
mv mpfr-3.0.1 gcc-4.7.1/mpfr
|
| 50 |
|
|
mv newlib-1.20.0/newlib gcc-4.7.1/newlib
|
| 51 |
|
|
mv newlib-1.20.0/libgloss gcc-4.7.1/libgloss
|
| 52 |
|
|
|
| 53 |
|
|
4. Build binutils:
|
| 54 |
|
|
mkdir binutils-build && cd binutils-build
|
| 55 |
|
|
../binutils-2.21/configure --prefix=$PREFIX --target=$TARGET --disable-nls
|
| 56 |
|
|
make
|
| 57 |
|
|
make install
|
| 58 |
|
|
cd ..
|
| 59 |
|
|
|
| 60 |
|
|
5. Build gcc:
|
| 61 |
|
|
mkdir gcc-build && cd gcc-build
|
| 62 |
|
|
../gcc-4.7.1/configure --prefix=$PREFIX --target=$TARGET --with-newlib \
|
| 63 |
|
|
--without-headers --with-gnu-ld --with-gnu-as --disable-libssp \
|
| 64 |
|
|
--disable-nls --enable-c99 --enable-long-long --enable-languages=c
|
| 65 |
|
|
make
|
| 66 |
|
|
make install
|
| 67 |
|
|
cd ..
|
| 68 |
|
|
|
| 69 |
|
|
At this point you have a complete toolchain located at $PREFIX.
