Fedora - Docker edition

The build dependencies are captured in a Dockerfile, the output of which is a .rpm for easy installation. This version takes longer since LLVM needs to be compiled from source.

  • Start with a recent Fedora install (tested with F22)
  • Install a >= 4.2 kernel with headers
  • Reboot
  • Install docker
  • Run the Dockerfile for Fedora - results in an installable .rpm
    • git clone https://github.com/iovisor/bcc; cd bcc
    • docker build -t bcc -f Dockerfile.fedora .
    • docker run --rm -v /tmp:/mnt bcc sh -c "cp /root/bcc/build/*.rpm /mnt"
    • sudo rpm -ivh /tmp/libbcc*.rpm
  • Run the example
    • sudo python /usr/share/bcc/examples/hello_world.py

Ubuntu - From 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

    • sudo apt-get -y install bison build-essential cmake flex git libedit-dev python zlib1g-dev

  • Build LLVM and Clang development libs

    • git clone http:https://llvm.org/git/llvm.git
    • cd llvm/tools; git clone http:https://llvm.org/git/clang.git
    • cd ..; mkdir -p build/install; cd build
    • cmake -G "Unix Makefiles" -DLLVM_TARGETS_TO_BUILD="BPF;X86" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=$PWD/install ..
    • make -j4
    • make install
    • export PATH=$PWD/install/bin:$PATH

  • 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
