[Pkg-phototools-devel] Bug#911022: flann breaks hugin autopkgtest: undefined symbol: LZ4_resetStreamHC

[Jochen Sprickerhof]

Hi Paul,

thanks for the report. The new flann version (1.9.1+dfsg-5) doesn't 
bundle lz4 anymore (as per policy and because it broke in Ubuntu, see 
LP: 1786543. I send a pull request to make use of pkg-config in Hugin:

https://salsa.debian.org/debian-phototools-team/hugin/merge_requests/1

@Andreas can you release a new Hugin version with this included? If you 
don't have time, I would push a NMU version to delayed/5, if that's ok 
with you.

Cheers Jochen
