本文详细介绍了为xNVMe项目准备构建工具链所需的步骤，包括更新到最新GCC、安装CMake、glibc等依赖项，确保系统满足C11标准及线程支持，并提供了一系列适用于Ubuntu 18.04的安装指导。

Please to see xNVME

Building xNVMe

Prepare Toolchain

Prepare Toolchain

The toolchain (compiler, archiver, and linker) used for building xNVMe must support C11, pthreads and on the system the following libraries and tools must be available:

glibc (>= 2.28, for io_uring/liburing)
libaio-dev (>=0.3, For xNVMe and SPDK)
libnuma-dev (>=2, For SPDK)
libssl-dev (>=1.1, For SPDK)
make (gmake)
meson (>=0.48, for SPDK)
ninja (>=, for SPDK)
uuid-dev (>=2.3, For SPDK)

Step 1 :update to latest gcc

sudo apt update
sudo apt install build-essential
sudo apt install gcc

check the gcc version:
gcc --version

Step 2: Install CMake (>= 3.9, For xNVMe)

 check the CMake version 
 cmake --version

So, I should update CMake <=3.9 version
Sometimes just install cmake by the command via
sudo apt install cmake
if you meet errors like that:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package CMake

solution for Ubuntu 18.04 Bionic is :

wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc 2>/dev/null | sudo apt-key add -
sudo apt-add-repository 'deb https://apt.kitware.com/ubuntu/ bionic main'
sudo apt-get update
sudo apt install cmake

install the latest cmake version

sudo apt remove cmake
pip install cmake --upgrade

you wiil see:

NOW: Install cmake3.9.2 in ubuntu18.04

wget https://cmake.org/files/v3.9/cmake-3.9.2.tar.gz
tar -xvf cmake-3.9.2.tar.gz
cd cmake-3.9.2
./configure
sudo make && make install

Check current Cmake version

hash -r
cmake --version

Step 3: Install glibc (>= 2.28, for io_uring/liburing)

check current glibc version:
ldd --version

在这里插入图片描述
By default, the highest version of GLIBC for Ubuntu 18.04 should 2.27

Step 4: Install glibc libaio-dev (>=0.3, For xNVMe and SPDK)

sudo apt-get update -y
sudo apt-get install -y libaio-dev

Step 5: Install libnuma-dev (>=2, For SPDK)

sudo apt-get update -y
sudo apt-get install -y libnuma-dev

在这里插入图片描述

Step 6: Install libssl-dev (>=1.1, For SPDK)

sudo apt-get update -y
sudo apt-get install -y libssl-dev

Step 7: Install make (gmake)

sudo apt update
sudo apt install make
sudo ln -s /usr/bin/make /usr/bin/gmake

在这里插入图片描述

Step 8: Install meson (>=0.48, for SPDK)

 sudo apt-get update -y 
 sudo apt-get install -y meson

在这里插入图片描述
Install meson from 0.45 to 0.48 or higher

sudo apt update
sudo apt install nasm
sudo apt install python3
sudo apt install python3-pip
pip3 install meson ninja

在这里插入图片描述
but!!! make error
While I can install with pip3 and it does indicate that it successfully installs 0.58.1

Reason:the newest meson is in the path~/.local/bin

Solution:

sudo ln -si /home/kathy-ub18/.local/bin/meson /usr/bin/meson

Step 9: Install uuid-dev (>=2.3, For SPDK)

sudo apt update
sudo apt install uuid-dev
