A simple set of instructions for building apache in a vagrant Ubuntu 14.04 can be found

[here,](tutorial.md) and for Ubuntu 16.04 [here.](tutorial-ubuntu-16.04.md)

# Building a recent Linux Kernel.
|
||||
|
||||
In this directory we include all the necessary files needed to
|
||||
build the kernel in a Ubuntu 16.04 vagrant box. We will guide the reader through
|
||||
the relatively simple task. We assume familiarity with [Vagrant.](https://www.vagrantup.com/)
|
||||
|
||||
## Vagrantfile
|
||||
|
||||
```ruby
|
||||
# -*- mode: ruby -*-
|
||||
# vi: set ft=ruby :
|
||||
|
||||
|
||||
Vagrant.configure("2") do |config|
|
||||
|
||||
config.vm.box = "ubuntu/xenial64"
|
||||
config.vm.provision :shell, path: "bootstrap.sh"
|
||||
|
||||
config.vm.provider "virtualbox" do |vb|
|
||||
vb.memory = "4096"
|
||||
vb.customize ["modifyvm", :id, "--ioapic", "on"]
|
||||
vb.customize ["modifyvm", :id, "--memory", "4096"]
|
||||
vb.customize ["modifyvm", :id, "--cpus", "4"]
|
||||
end
|
||||
|
||||
end
|
||||
```
|
||||
|
||||
## Bootstrapping
|
||||
|
||||
```bash
|
||||
#!/usr/bin/env bash
|
||||
|
||||
sudo apt-get update
|
||||
|
||||
sudo apt-get install -y emacs24 dbus-x11

|
||||
|
||||
echo ". /vagrant/bash_profile" >> /home/vagrant/.bashrc
|
||||
```
|
||||
|
||||
## Shell Settings
|
||||
|
||||
```bash
|
||||
#### llvm
|
||||
export LLVM_HOME=/usr/lib/llvm-5.0
|
||||
export GOPATH=/vagrant/go

|
||||
export PATH=${GOPATH}/bin:${LLVM_HOME}/bin:${PATH}
|
||||
```
|
||||
|
||||
|
||||
|
||||
## Configuration stuff.
|
||||
|
||||
The file `tinyconfig64` is generated ...
|
||||
|
||||
## The Build with gllvm
|
||||
|
||||
The build process is carried out by running the `build_linux_gllvm.sh`
|
||||
script.
|
||||
|
||||
```bash
|
||||
#!/usr/bin/env bash
|
||||
|
||||
mkdir -p ${GOPATH}
|
||||
go get github.com/SRI-CSL/gllvm/cmd/...
|

|

|
||||
|
||||

|
||||
|
||||
get-bc -m -b built-in.o
|
||||
get-bc -m vmlinux
|
||||
```
|
||||
|
||||
## The Build with wllvm
|
||||
|
||||
The build process is carried out by running the `build_linux_wllvm.sh`
|
||||
script.
|
||||
|
||||
```bash
|
||||
#!/usr/bin/env bash
|
||||
|
||||
sudo pip install wllvm
|
||||
|
||||
mkdir ${HOME}/linux_kernel
|

cd ${HOME}/linux_kernel
|

# Compiling Apache on Ubuntu
|
||||
|
||||
|
||||
On a clean 16.04 server machine I will build apache. Desktop instructions should be no different.
|
||||
|
||||
```
|
||||
>more /etc/lsb-release
|
||||
|
||||
DISTRIB_ID=Ubuntu
|
||||
DISTRIB_RELEASE=16.04
|
||||
DISTRIB_CODENAME=xenial
|
||||
DISTRIB_DESCRIPTION="Ubuntu 16.04 LTS"
|
||||
```
|
||||
|
||||
|
||||
## Step 1.
|
||||
|
||||
Install `gllvm`.
|
||||
|
||||
```
|
||||
>export GOPATH=/vagrant/go
|
||||
|
||||
>mkdir -p ${GOPATH}
|
||||
|
||||
>go get github.com/SRI-CSL/gllvm/cmd/...
|
||||
|
||||
>export PATH=${GOPATH}/bin:${PATH}
|
||||
```
|
||||
|
||||
## Step 2.
|
||||
|
||||
I am only going to build apache, not apr, so I first install the prerequisites.
|
||||
|
||||
```
|
||||
>sudo apt-get install llvm libclang-dev clang libapr1-dev libaprutil1-dev libpcre3-dev make
|
||||
|
||||
```
|
||||
|
||||
At this point, you could check your clang version with `which clang` and `ls -l /usr/bin/clang`.
|
||||
It should be at least clang-3.8.
|
||||
|
||||
## Step 3.
|
||||
|
||||
Configure the gllvm tool to be relatively quiet:
|
||||
|
||||
```
|
||||
>export WLLVM_OUTPUT_LEVEL=WARNING
|
||||
>export WLLVM_OUTPUT_FILE=/vagrant/apache-build.log
|
||||
```
|
||||
|
||||
## Step 4.
|
||||
|
||||
Fetch apache, untar, configure, then build:
|
||||
|
||||
```
|
||||
|
||||
>wget https://archive.apache.org/dist/httpd/httpd-2.4.33.tar.gz
|
||||
|
||||
>tar xfz httpd-2.4.33.tar.gz
|
||||
|
||||
>cd httpd-2.4.33
|
||||
|
||||
>CC=gllvm ./configure
|
||||
|
||||
>make
|
||||
```
|
||||
|
||||
## Step 5.
|
||||
|
||||
Extract the bitcode.
|
||||
|
||||
```
|
||||
>get-bc httpd
|
||||
|
||||
>ls -la httpd.bc
|
||||
-rw-r--r-- 1 vagrant vagrant 1119584 Aug 4 20:02 httpd.bc
|
||||
```
|
||||
|
||||
## Step 6.
|
||||
|
||||
Turn the bitcode into a second executable binary. (optional -- just for fun and sanity checking)
|
||||
|
||||
```
|
||||
llc -filetype=obj httpd.bc
|
||||
gcc httpd.o -lpthread -lapr-1 -laprutil-1 -lpcre -o httpd.new
|
||||

|

DISTRIB_DESCRIPTION="Ubuntu 14.04.2 LTS"
|
||||
```
|
||||
|
||||
|
||||
## Step 1.
|
||||
|
||||
|
||||
Install `gllvm`.
|
||||
|
||||
```
|
||||
>export GOPATH=/vagrant/go
|
||||
|
||||
>mkdir -p ${GOPATH}

||||
## Step 2.
|
||||
|
||||
I am only going to build apache, not apr, so I first install the prerequisites.
|
||||
|
||||
```
|
||||
>sudo apt-get install llvm libclang-dev clang libapr1-dev libaprutil1-dev
|
||||
|
||||
``` Note `gclang` is agnostic with respect to llvm versions
|
||||
so feel free to install a more recent version if you
|
||||
wish. However, if you are going to use dragonegg the llvm version is
|
||||
tightly coupled to the gcc and plugin versions you are using.
|
||||
|
||||
|
||||
## Step 3.
|
||||
|
||||
Configure the gllvm tool to be relatively quiet:
|
||||
|

```
|

>export WLLVM_OUTPUT_LEVEL=WARNING
