解决办法
这是因为os本身系统库不兼容的问题,首先因为我是在macos上编译linux的版本,所以需要安装:
brew install FiloSottile/musl-cross/musl-cross
如果你是在macos上编译运行在win下的exe,那么需要安装:
brew install mingw-w64
==> Downloading https://homebrew.bintray.com/bottles/gmp-6.2.1.big_sur.bottle.tar.gz
==> Downloading from https://d29vzk4ow07wi7.cloudfront.net/6a44705536f25c4b9f8547d44d129ae3b3657755039966ad2b86b821e187c32c?response-content-dispositio
同时编译的参数也需要调整如下:
GOOS=linux GOARCH=amd64 CGO_ENABLED=1 CC=x86_64-linux-musl-gcc CXX=x86_64-linux-musl-g++ go build -ldflags="-s -w" -trimpath -o release/githubMonitor_linux main.go
这个时候直接放到linux也是不能运行的,需要安装musl
sudo yum install -y musl-libc-static
sudo apt-get install -y musl musl-dev
