tomilov / get and build latest boost on ubuntu.lua
Last active November 24, 2015 05:33
Lua script to clone latest revision of boost repository and to clone latest revisions of all the submodules. Also containing hints of how to build and install boost complitely. The download traffic is minimal possible: only single branch, only latest revision of the branch.
-- mkdir boost ; cd boost ; lua ../git-submodules-clone-HEAD.lua https://github.com/boostorg/boost.git .
local module_url = arg[1] or 'https://github.com/boostorg/boost.git'
local module = arg[2] or module_url:match('.+/([_%d%a]+)%.git')
local branch = arg[3] or 'master'
function execute(command)
print('# ' .. command)
return os.execute(command)
end
-- execute('rm -rf ' .. module)
if not execute('git clone --single-branch --branch ' .. branch .. ' --depth=1 ' .. module_url .. ' ' .. module) then
