WSL安裝 perf工具

WSL中安裝perf工具時，按照一般安裝方法，安裝linux-tools-common後，執行perf工具提示

WARNING: perf not found for kernel 4.4.0-18362

You may need to install the following packages for this specific

kernel:

linux-tools-4.4.0-18362-Microsoft

linux-cloud-tools-4.4.0-18362-Microsoft

You may also want to install one of the following packages to keep up

to date:

linux-tools-Microsoft

linux-cloud-tools-Microsoft

然而以上安裝包在apt-get中找不到，是以重新使用源碼編譯的方法安裝perf

首先安裝編譯工具

sudo apt install build-essential flex bison libssl-dev libelf-dev
           

然後下載下傳WSL源碼

git clone --depth=1 https://github.com/microsoft/WSL2-Linux-Kernel.git
           

github下載下傳如果比較慢，gitee有鏡像源

git clone https://gitee.com/mirrors/WSL2-Linux-Kernel.git
           

下載下傳完成後，進行編譯

cd WSL2-Linux-Kernel/tools/perf
make
           

編譯成功後，即可在此檔案夾下找到perf工具，執行成功，也可以自行将perf工具移動到/usr/bin檔案夾下友善調用
