[flann] Build step `make doc` fails

[iFreilicht]

I've tried to build the flann package from the AUR directly, and the whole build works, except for the make doc step:

I modified my local PKGBUILD and removed the line make doc, see the patch below:

diff --git a/PKGBUILD b/PKGBUILD

 }

 package() {

Obviously, this is just a workaround, not a solution, but running make doc directly from src/ yields the same output as what I pasted above, so I'm not sure how to troubleshoot.

@iFreilicht Sorry for getting back to you late on this.

Are you still facing this problem?

I am not able to replicate it. If you still are facing this problem, then I'll go ahead and remove the make doc step as thats not really necessary for the package itself.

If I dont hear back in a week, I'll go ahead and close this issue without taking an further action.

I didn't try to install it again. Maybe this was just a temporary issue with packages on my system. I'll try to test this again this week to make sure.

Closing this issue, due to not being able to reproduce and inactivity.
