From: David MacMahon Date: Sat, 2 Mar 2013 11:06:42 -0800 Subject: Add --enable-autobuild option This enables the automatic download and build of the pgplot library only if the user provides the --enable-autobuild option. This is more security conscious as it requires the user's explicit permission (by providing --enable-autobuild) to download and install this third party library. --- ext/extconf-auto.rb | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) diff --git a/ext/extconf-auto.rb b/ext/extconf-auto.rb index 64020d1..5891862 100644 --- a/ext/extconf-auto.rb +++ b/ext/extconf-auto.rb @@ -14,7 +14,24 @@ load "./extconf.rb" +# Exit if user did not specify "--enable-autobuild" +if !enable_config('autobuild', false) + # Print reminder about --enable-autobuild option if pgplot was not found + if !$have_pgplot + puts + puts "The PGPLOT library was not found.
