ZeroVM gcc toolchain
How to build the full toolchain from scratch
Install Prerequisites
Ubuntu 12.04
Toolchain requires multiple dependencies, including
zerovm-zmq-dev. To install zerovm-zmq-dev,
first choose from one of the following PPAs:
- Latest: ppa:zerovm-ci/zerovm-latest
- Stable: ppa:zerovm-ci/zerovm-stable
Add the PPA to your sources list:
sudo apt-get install python-software-properties
sudo add-apt-reposistory ppa:zerovm-ci/zerovm-latest
# or 'sudo add-apt-repository ppa:zerovm-ci/zerovm-stable'
sudo apt-get update
Install dependencies:
sudo apt-get install libc6-dev-i386 libglib2.0-dev pkg-config git \
build-essential automake autoconf libtool g++-multilib texinfo \
flex bison groff gperf texinfo subversion \
zerovm-zmq-dev
Setup Environment Variables
You need to set them up prior to building anything. We'll use the following variables:
ZVM_PREFIX: should point to an empty writable directory all files will be installed here aftermake installZRT_ROOT: should point to git clone ofzrtrepositoryLD_LIBRARY_PATH: library path for libvalidator.so (from zvm-validator)CPATH: include directory containingzvm.h(fromzerovm-zmq-dev)
We will use these values for this guide:
export ZVM_PREFIX=$HOME/zvm-root
export ZRT_ROOT=$HOME/zrt
export LD_LIBRARY_PATH=/usr/lib64
export CPATH=/usr/x86_64-nacl/include
Clone Things
git clone https://github.com/zerovm/zrt.git $ZRT_ROOT
git clone https://github.com/zerovm/toolchain.git $HOME/zvm-toolchain
cd $HOME/zvm-toolchain/SRC
git clone https://github.com/zerovm/linux-headers-for-nacl.git
git clone https://github.com/zerovm/gcc.git
git clone https://github.com/zerovm/glibc.git
git clone https://github.com/zerovm/newlib.git
git clone https://github.com/zerovm/binutils.git
Build Toolchain
cd $HOME/zvm-toolchain
make -j8 ZEROVM=`which zerovm` # e.g., '/usr/bin/zerovm'
If something goes wrong you will need to delete everything
(apart from zerovm and validator) in the $ZVM_PREFIX directory and
only then do make clean and make (this is how the gcc
toolchain works, sadly).
Example of cleanup procedures:
cd $HOME/zvm-toolchain
make clean
cd $ZVM_PREFIX
rm -rf *
cd $ZEROVM_ROOT
make install PREFIX=$ZVM_PREFIX
Install Debugger
Debugger prerequisites:
sudo apt-get install flex bison groff libncurses5-dev libexpat1-dev
cd $HOME/zvm-toolchain/SRC
git clone https://github.com/zerovm/gdb.git
cd gdb
mkdir BUILD
cd BUILD
../configure --program-prefix=x86_64-nacl- --prefix=$ZVM_PREFIX
make -j4
make install
