最近在学习bpf，记录下安装bcc流程

环境

Redhat8
kernel-5.4.83

1. 编译llvm

编译 LLVM 和 Clang 开发库

git clone https://github.91chifun.workers.dev//https://github.com/llvm-mirror/llvm.git
cd llvm/tools; git clone https://github.91chifun.workers.dev//https://github.com/llvm-mirror/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=$PWD/install ..
make
make install
export PATH=$PWD/install/bin:$PATH

2. bcc 编译要求

sudo yum  install -y bison cmake ethtool flex git iperf libstdc++-static \
  python-netaddr python-pip gcc gcc-c++ make zlib-devel \
  elfutils-libelf-devel
sudo yum install -y luajit luajit-devel  # for Lua support
sudo yum install -y \
  http://repo.iovisor.org/yum/extra/mageia/cauldron/x86_64/netperf-2.7.0-1.mga6.x86_64.rpm
sudo pip install pyroute2

3. build bcc

cd bcc
mkdir build 
cd build 

#cmake ..
make -j
make install

测试：

[root@localhost tools]# pwd
/usr/local/share/bcc/tools
[root@localhost tools]#  ./filetop
