Solved how to build blktap from sources?
hui ... will try that ...
@nraynaud said in how to build blktap from sources?:
whats inside this directory? content of the XenServer 7.4 source iso?
ahh... maybe this? https://updates.xcp-ng.org/7/dev/builddeps/x86_64/Packages/
ok, got it working! my own blktap is running Thanks for your help!

First just playing around to get knowledge of this, maybe I find some usefull things. Don't know exactly, but I want to understand a bit more what I'm using here.
Can sometimes be handy to know such things. Everytime I learned something I was using it later at work or privat

Good idea We are glad to have more potential contributors on board. More the XCP-ng knowledge is spread, better the community!

There's now a new and reproducible way to build blktap in a clean environment:
I will not copy the readme here, but basically, you can do something like that:
# create the build image, target current dev branch of XCP-ng (which is the future 7.5) # There's no support for 7.4 because of different repository structure and missing devel packages # You need to do it just once, though doing it from time to time won't hurt. ./build.sh dev # create an useful alias for later. You should probably add it to you .bashrc so that it stays # The --rm part is not mandatory but I find it useful to keep docker's disk usage low. alias xcp-build="$(pwd)/run.py --rm"
Here I'll show you how to build from our new git repositories. Not all packages are present there, but blktap is and this is a good occasion to make you become accustomed to using them since that's where we'll commit patches and also experimental stuff.
# from the directory of your choice... git clone https://github.com/xcp-ng-rpms/blktap.git # or a forked version if you intend to send pull requests cd blktap # ... here make changes... or not... # use our shiny new alias to build it xcp-build --build-local . # or simply 'xcp-build -l .'
The resulting built RPMs will be in the SRPMS and RPMS subdirectories of your git working directory.
Just tested with blktap. If it fails at building another package, open a separate thread and I'll try to fix it.
Bonus: build with experimental changes applied
Our blktap package can be built with an experimental patch for better ZFS support. Build it this way:
xcp-build --build-local . --define 'xcp_ng_section extras'

If someone fails to build, maybe the git-lfs in not properly initialised. To fetch the lfs-files after
git cloneyou can do a
git lfs fetch.
weird ... after the second time installing git-lfs and again cloning the repo, it worked...
