9. Develop Environment
9.1. Centos7
9.1.1. How to install higher version gcc on centos7 docker?
Ref: https://stackoverflow.com/questions/67090507/how-to-install-gcc-g-9-on-centos-7-docker-centos7
FROM centos:7 AS env
RUN yum update -y && \
yum install -y centos-release-scl && \
yum install -y devtoolset-9 && \
echo "source /opt/rh/devtoolset-9/enable" >> /etc/bashrc
9.2. CMAKE
9.2.1. cudatoolkit version and supported gpus
9.2.2. How to get the version of library found by CMake?
Ref: https://stackoverflow.com/questions/34138886/how-to-know-version-of-library-found-by-cmake
<package>_VERSION
9.2.3. How to build x86 or x64 on Windows from command line with CMAKE?
cmake -G "Visual Studio 17 2022" -A Win32 -S .. -B "build32"
cmake -G "Visual Studio 17 2022" -A x64 -S .. -B "build64"
cmake --build build32 --config Release
cmake --build build64 --config Release
For simplicity, only build 64bit version:
cmake .. -A x64
cmake --build . --config Release
9.2.4. ld: warning: missing .note.GNU-stack section implies executable stack
This is a new warning message introduced by GNU bin-utils version 2.39.
出现“ld missing .note.GNU-stack section implies executable stack”的错误提示， 通常是因为在链接过程中，某些对象文件缺少.note.GNU-stack节，导致链接器默认认为可能需要一个可执行的栈。 这在现代操作系统中是不推荐的做法，因为可执行的栈可能会导致安全问题，如缓冲区溢出攻击。
需要在汇编码中加入：
.section .note.GNU-stack,"",@progbits
或者编译选项：
if(UNIX)
set_property(TARGET target APPEND_STRING PROPERTY LINK_FLAGS "-z noexecstack")
endif()
9.3. Conda
9.3.1. conda命令补全
参考： https://github.com/tartansandal/conda-bash-completion
采用方法2直接把 https://github.com/tartansandal/conda-bash-completion/blob/master/conda 下载到bash补全目录
9.4. Docker
9.4.1. Manage Docker as a non-root user
reference: https://docs.docker.com/engine/install/linux-postinstall/
If
dockergroup does not exit:
sudo groupadd docker
Add your user to the
dockergroup:
sudo usermod -aG docker $USER
To activate the changes to groups:
newgrp docker
9.5. manylinux
centos7, glibc version 2.17
9.6. git
9.6.1. 在 HTTPS 端口使用 SSH
参考：https://docs.github.com/zh/authentication/troubleshooting-ssh/using-ssh-over-the-https-port
Host github.com
Hostname ssh.github.com
Port 443
User git
9.7. Homebrew
由于tencent的homebrew源有问题，所以暂用科大源替代。
9.7.1. 科大源安装 Homebrew / Linuxbrew
首先在命令行运行如下几条命令设置环境变量：
export HOMEBREW_BREW_GIT_REMOTE="https://mirrors.ustc.edu.cn/brew.git"
export HOMEBREW_BOTTLE_DOMAIN="https://mirrors.ustc.edu.cn/homebrew-bottles"
export HOMEBREW_API_DOMAIN="https://mirrors.ustc.edu.cn/homebrew-bottles/api"
之后在命令行运行 Homebrew 安装脚本：
/bin/bash -c "$(curl -fsSL https://github.com/Homebrew/install/raw/HEAD/install.sh)"
备注
若用户设置了环境变量 HOMEBREW_BREW_GIT_REMOTE，则每次运行 brew update 时将会自动设置远程。
推荐用户将环境变量 HOMEBREW_BREW_GIT_REMOTE 加入 shell 的 profile 设置中。
# 对于 bash 用户
echo 'export HOMEBREW_BREW_GIT_REMOTE="https://mirrors.ustc.edu.cn/brew.git"' >> ~/.bash_profile
# 对于 zsh 用户
echo 'export HOMEBREW_BREW_GIT_REMOTE="https://mirrors.ustc.edu.cn/brew.git"' >> ~/.zshrc
重置为官方地址：
unset HOMEBREW_BREW_GIT_REMOTE
git -C "$(brew --repo)" remote set-url origin https://github.com/Homebrew/brew
备注
重置回默认远程后，用户应该删除 shell 的 profile 设置中的环境变量 HOMEBREW_BREW_GIT_REMOTE 以免运行 brew update 时远程再次被更换。
若之前使用的 git config url.<URL>.insteadOf URL 的方式设置的镜像，请手动删除 config 文件（一般为 ~/.gitconfig 或仓库目录下的 .git/config）中的对应字段。
9.7.2. Linux Homebrew参考设置
export HOMEBREW_BREW_GIT_REMOTE="https://mirrors.ustc.edu.cn/brew.git"
export HOMEBREW_BOTTLE_DOMAIN="https://mirrors.ustc.edu.cn/homebrew-bottles"
export HOMEBREW_API_DOMAIN="https://mirrors.ustc.edu.cn/homebrew-bottles/api"
eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"
if type brew &>/dev/null
then
HOMEBREW_PREFIX="$(brew --prefix)"
if [[ -r "${HOMEBREW_PREFIX}/etc/profile.d/bash_completion.sh" ]]
then
source "${HOMEBREW_PREFIX}/etc/profile.d/bash_completion.sh"
else
for COMPLETION in "${HOMEBREW_PREFIX}/etc/bash_completion.d/"*
do
[[ -r "${COMPLETION}" ]] && source "${COMPLETION}"
done
fi
fi
9.7.3. 通过brew安装的vim启动时出现错误
解决方法：
brew reinstall --build-from-source vim
