Can not run a cpp with dap.

[weiyshay]

Hi,
I am not able to start a cpp executable with the following error message:

Path to executable: /code/src/demo/vector/Error executing Lua callback: ...l/share/nvim/site/pack/packer/start/nvim-dap/lua/dap.lua:485: ...nvim/site/pack/packer/start/nvim-dap/lua/dap/session.lua:1309: Error running ~/.local/share
/nvim/mason/bin/OpenDebugAD7: ENOENT: no such file or directory

I have double-checked both the files are in the location, anyone knows what I am missing? Appreciate your ideas!

ls -l /code/src/demo/vector/vector     
-rwxr-xr-x 1 root root 80432 Mar  8 01:33 /code/src/demo/vector/vector*

ll ~/.local/share/nvim/mason/bin/OpenDebugAD7
lrwxrwxrwx 1 root root 88 Mar  8 01:43 /root/.local/share/nvim/mason/bin/OpenDebugAD7 -> /root/.local/share/nvim/mason/packages/cpptools/extension/debugAdapters/bin/OpenDebugAD7*

My configuration with cpptools installed via mason:

local dap = require("dap")

dap.adapters.cppdbg = {
    id = "cppdbg",
    type = 'executable',
    command = "~/.local/share/nvim/mason/bin/OpenDebugAD7"
    -- command = "command = "~/.local/share/nvim/mason/bin/OpenDebugAD7"~/.local/share/nvim/mason/packages/cpptools/extension/debugAdapters/bin/OpenDebugAD7",
}

dap.configurations.cpp = {
    {
        name = "Launch file",
        type = "cppdbg",
        request = "launch",
        program = function()
            return vim.fn.input("Path to executable: ", vim.fn.getcwd() .. "/", "file")
        end,

        cwd = "${workspaceFolder}",
        stopAtEntry = true,
    },
}
dap.configurations.c = dap.configurations.cpp

~ is not automatically expanded to your home folder. You need to use the absolute path, or add OpenDebugAD7 to your $PATH and use just OpenDebugAD7.

Thank you very much! It works after I exported the PATH.
