[erlang-questions] kerl usage (was Patch package OTP 21.1.1 released)

[Boroska András]

Hi!

One can also use kerl with a local git repo, thus avoiding the large
download before each build by using git fetch.

When setting the default install directory in ~/.kerlrc as
KERL_DEFAULT_INSTALL_DIR=~/myotpinst

the following will install what you wanted:

cd ~/github/otp # the git repo
git fetch
kerl build git ~/github/otp OTP-21.1.1 r21.1.1
kerl install  r21.1.1
