The following instructions are known to work on Linux, macOS, Windows and FreeBSD.
With Go version 1.16 or later:
# Install the latest release:
$ go install github.com/go-delve/delve/cmd/dlv@latest
# Install from tree head:
$ go install github.com/go-delve/delve/cmd/dlv@master
# Install a specific version or pseudo-version:
$ go install github.com/go-delve/delve/cmd/[email protected]
$ go install github.com/go-delve/delve/cmd/[email protected]
See Versions and Pseudo-versions for how to format the version suffixes.
Alternatively, clone the git repository and build:
$ git clone https://github.com/go-delve/delve
$ cd delve
$ go install github.com/go-delve/delve/cmd/dlv
See go help install for details on where the dlv executable is saved.
If during the install step you receive an error similar to this:
found packages native (proc.go) and your_operating_system_and_architecture_combination_is_not_supported_by_delve (support_sentinel.go) in /home/pi/go/src/github.com/go-delve/delve/pkg/proc/native
It means that your combination of operating system and CPU architecture is not supported, check the output of go version.
On macOS make sure you also install the command line developer tools:
$ xcode-select --install
If you didn't enable Developer Mode using Xcode you will be asked to authorize the debugger every time you use it. To enable Developer Mode and only have to authorize once per session use:
sudo /usr/sbin/DevToolsSecurity -enable
You might also need to add your user to the developer group:
sudo dscl . append /Groups/_developer GroupMembership $(whoami)
You do not need the macOS native backend and it has known problems. If you still want to build it:
- Run
xcode-select --install - On macOS 10.14 manually install the legacy include headers by running
/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg - Clone the repo into
$GOPATH/src/github.com/go-delve/delve - Run
make installin that directory (on some versions of macOS this requires being root, the first time you run it, to install a new certificate)
The makefile will take care of creating and installing a self-signed certificate automatically.
