Re: [Mingw-cross-env-list] Help narrowing down a build error depending on plattform

[Gilles Caulier]

I vote to update lensfun to last stable 0.3.2. It have been released sine a while and Lensfun team take time to release next one, as a lots of API will be broken due huge changes in core implementation. So 0.3.2 is LTS like version.

I sent a pull request to update MXE's lensfun to 0.3.2

Can you check that it works in digikam, please?
