Dear all, I'm currently unable to build GHC's master branch as some of the submodules (presumably used by Hadrian) are making git pretty unhappy (I've used various variants of the command below, in a cleaned repository): ```console $ git submodule update --init error: submodule git dir '/home/aspiwack/projects/tweag/ghc/master/.git/modules/hadrian/vendored/Cabal' is inside git dir '/home/aspiwack/projects/tweag/ghc/master/.git/modules/hadrian' fatal: refusing to create/use '/home/aspiwack/projects/tweag/ghc/master/.git/modules/hadrian/vendored/Cabal' in another submodule's git dir Failed to clone 'hadrian/vendored/Cabal'. Retry scheduled error: submodule git dir '/home/aspiwack/projects/tweag/ghc/master/.git/modules/hadrian/vendored/Cabal' is inside git dir '/home/aspiwack/projects/tweag/ghc/master/.git/modules/hadrian' fatal: refusing to create/use '/home/aspiwack/projects/tweag/ghc/master/.git/modules/hadrian/vendored/Cabal' in another submodule's git dir Failed to clone 'hadrian/vendored/Cabal' a second time, aborting ``` Please advise on how to get unblocked. And, if I'm allowed to conclude with a plea: please be careful not to abuse Git's submodule system, it's wonky enough when used simply. -- Arnaud Spiwack Director, Research at https://moduscreate.com and https://tweag.io.
