# --------------------------------------------------------------------------
# The install phase installs the Oniguruma library,
# which is a dependency for building grok_exporter.
# We use Cygwin and MinGW to cross-compile Oniguruma for Windows.

install:

    # Update the Cygwin environment

    # Uncomment the following command to upgrade the cygwin packages:
    # - C:\cygwin\setup-x86.exe -q -g
    - C:\cygwin64\bin\bash -lc "cygcheck -dc cygwin"

    # Download and unpack Oniguruma sources

    - cd C:\

    - cd onig-6.9.5
