Installing BCC

Kernel Configuration

In general, to use these features, a Linux kernel version 4.1 or newer is required. In addition, the kernel should have been compiled with the following flags set:

CONFIG_BPF=y
CONFIG_BPF_SYSCALL=y
# [optional, for tc filters]
CONFIG_NET_CLS_BPF=m
# [optional, for tc actions]
CONFIG_NET_ACT_BPF=m
CONFIG_BPF_JIT=y
CONFIG_HAVE_BPF_JIT=y
# [optional, for kprobes]
CONFIG_BPF_EVENTS=y

Kernel compile flags can usually be checked by looking at /proc/config.gz or /boot/config-<kernel-version>.

Packages

Ubuntu - Binary

Install a 4.3+ kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline, for example:

VER=4.4.2-040402
PREFIX=http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.2-wily/
REL=201602171633
wget ${PREFIX}/linux-headers-${VER}-generic_${VER}.${REL}_amd64.deb
wget ${PREFIX}/linux-headers-${VER}_${VER}.${REL}_all.deb
wget ${PREFIX}/linux-image-${VER}-generic_${VER}.${REL}_amd64.deb
sudo dpkg -i linux-*${VER}.${REL}*.deb
# reboot

Update PREFIX to the latest date, and you can browse the files in the PREFIX url to find the REL number.

Tagged and signed bcc binary packages are built for Ubuntu Trusty (14.04) and hosted at http://52.8.15.63/apt/.

To install:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D4284CDD
echo "deb http://52.8.15.63/apt trusty main" | sudo tee /etc/apt/sources.list.d/iovisor.list
sudo apt-get update
sudo apt-get install libbcc libbcc-examples python-bcc

Test it: sudo python /usr/share/bcc/examples/hello_world.py sudo python /usr/share/bcc/examples/tracing/task_switch.py

(Optional) Install pyroute2 for additional networking features

git clone https://github.com/svinota/pyroute2
cd pyroute2; sudo make install
sudo python /usr/share/bcc/examples/simple_tc.py

Fedora - Binary

Install a 4.2+ kernel from http://alt.fedoraproject.org/pub/alt/rawhide-kernel-nodebug, for example:

sudo dnf config-manager --add-repo=http://alt.fedoraproject.org/pub/alt/rawhide-kernel-nodebug/fedora-rawhide-kernel-nodebug.repo
sudo dnf update
# reboot

Nightly bcc binary packages are built for Fedora 23 and 24, hosted at http://52.8.15.63/yum/nightly/f{23,24}.

To install (change 'f23' to 'f24' for rawhide):

echo -e '[iovisor]\nbaseurl=http://52.8.15.63/yum/nightly/f23/$basearch\nenabled=1\ngpgcheck=0' | sudo tee /etc/yum.repos.d/iovisor.repo
sudo dnf install bcc-tools

Arch - AUR

Upgrade the kernel to minimum 4.3.1-1 first; the CONFIG_BPF_SYSCALL=y configuration was not added until this kernel release.

Install these packages using any AUR helper such as pacaur, yaourt, cower, etc.:

bcc bcc-tools python-bcc python2-bcc

All build and install dependencies are listed in the PKGBUILD and should install automatically.

Source

Ubuntu - Source

To build the toolchain from source, one needs:

  • LLVM 3.7 or newer, compiled with BPF support (default=on)
  • Clang 3.7, built from the same tree as LLVM
  • cmake, gcc (>=4.7), flex, bison

Install build dependencies

# Trusty and older
VER=trusty
echo "deb http://llvm.org/apt/$VER/ llvm-toolchain-$VER-3.7 main
deb-src http://llvm.org/apt/$VER/ llvm-toolchain-$VER-3.7 main" | \
  sudo tee /etc/apt/sources.list.d/llvm.list
wget -O - http://llvm.org/apt/llvm-snapshot.gpg.key | sudo apt-key add -
sudo apt-get update

# All versions
sudo apt-get -y install bison build-essential cmake flex git libedit-dev \
  libllvm3.7 llvm-3.7-dev libclang-3.7-dev python zlib1g-dev

Install and compile BCC

git clone https://github.com/iovisor/bcc.git
mkdir bcc/build; cd bcc/build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr
make
sudo make install
