Description kuerbiskern 2020-04-28 19:02:57 UTC
This is a gentoo machine on ~amd64. =net-fs/davfs2-1.5.6 does not build against net-libs/neon-0.31.1 though both are the newest version available.
From what I understand only versions lower than 0.31.0 are supported. See the build log which states: configure: incompatible neon library version 0.31.1: wanted 0.27 28 29 30

workaround: Mask >net-libs/neon-0.30.2 in /etc/portage/package.mask, emerge davfs2.

Reproducible: Always

Steps to Reproduce:
1. move ~amd64
2. 'emerge davfs2'
3. watch neon being installed in version 0.31.1 and configure of davfs2 failing
Actual Results:  
Build against not suitable neon version and configuring davfs2 failing.

Expected Results:  
Build against suitable version and davfs2 being installed.

Portage should have installed suitable versions.

Patch for building against neon-0.31

There's a patch at that suggests that support is already added and that it's just the build scripts that needs to be updated.
I took the patch from there and added a few things which makes it build fine here.
