go version
Using system packages
- just a package:
su - #### as root # cleanup apt-get autoremove --purge golang\* ## from Debian STABLE: sudo apt-get install golang # Stable package ## or Debian BACKPORT: sudo apt-get -t stretch-backports install golang ## to DEBUG, install also gdb: sudo apt-get install gdb # exit
- and setup your user environment (you can put the follow in ~/.profile)
export GOROOT="/home/shared/opt/software/golang" # Edit when needed
export GOPATH="${HOME}/.golang"
export PATH="${PATH}:${GOROOT}/bin:${GOPATH}/bin"
Test
mkdir -p "$HOME/tmp"
cd "$HOME/tmp"
go mod init example.com/hello
cat > hello.go <<EOF
package main
import "fmt"
func main() {
fmt.Printf("hello, world\n")
}
EOF
go build
./hello
# hello, world
Troubles
In case of dependencies problems, e.g.
go: verifying github.com/labstack/echo@v3.3.5+incompatible: checksum mismatch
clean the checksum file:
rm go.sum go clean -modcache

IDEs
GoClipse
- NOTE, the project is outdated
1) add goclipse plugin from http://goclipse.github.io/releases/
2) configure and install gocode, guru, godef tools
go get -u github.com/nsf/gocode go get -u golang.org/x/tools/cmd/guru go get -u github.com/rogpeppe/godef
3) configure build target using a Makefile, and run it from project_folder->right_click->build
make -C ${project_loc} debug
4) add a simple Makefile, like
debug:
go build -v -gcflags=all="-N -l" ./cmd/YOUR_PACKAGE
