Subject: [PATCH] Generate .lib files on PE platforms
Date: Wed, 03 May 2017 11:27:00 -0000 [thread overview]
Message-ID: <cc063f74-e890-36df-e283-b46b0544ac4b@qt.io> (raw)
MSVC needs them to link against .dll files. gcc can do without, so we
only need to do this when actually installing the files. There is a way
to generate .lib files with dlltool, but most of the time MSVC won't
cleanly link against the result, so we rather use lib.exe here.
