Failure to compile 0.35 on Ubuntu 20.04

[p-phillips]

I'm trying to upgrade my R packages on an Ubuntu 20.04 install to git2r 0.35

I've got libgit2-dev installed:

# apt list --installed| egrep libgit
libgit-wrapper-perl/focal,focal,now 0.048-1 all [installed,automatic]
libgit2-28/focal-updates,focal-security,now 0.28.4+dfsg.1-2ubuntu0.1 amd64 [installed,automatic]
libgit2-dev/focal-updates,focal-security,now 0.28.4+dfsg.1-2ubuntu0.1 amd64 [installed,automatic]
libgit2-glib-1.0-0/focal,now 0.28.0.1-2 amd64 [installed,automatic]
libgit2-glib-1.0-dev/focal,now 0.28.0.1-2 amd64 [installed]
libgitlab-api-v4-perl/focal,focal,now 0.25-1 all [installed,automatic]

but I'm getting the

configure: error: package dependency requirement 'libgit2 >= 1.0' could not be satisfied.
See 'config.log' for more details
ERROR: configuration failed for package ‘git2r’

error message. I've installed the GIT MAINTAINERS ppa but still the same error message.

My suspicion is that my problem is that I don't have a sufficiently up to date version of the development libraries? - I can't find anything obvious regarding a libgit2-dev PPA that would upgrade the library from 0.28.4.

Advice appreciated. Thanks. Pete

Yes, I bumped the version of libgit2 to >= 1.0. It was challenging to check for multiple libgit2 API differences in the configuration and I decided to move forward. I am sorry that this is causing you difficulties in installing version 0.35. There are no other changes in that version so you can continue to use the previous version of git2r.

Any advice on what the options would be in future ? This is likely to burn anyone still on a long term supported version of Ubuntu.

The error message indicates that you need to install a version of libgit2 that is greater than or equal to version 1.0. On Ubuntu you can apparently get that from the 'universe' repository or from here: https://ubuntu.pkgs.org/24.04/ubuntu-universe-amd64/libgit2-glib-1.0-0_1.2.0-1build4_amd64.deb.html . I would suggest that 'options for the future' include installation of the required dependency to avoid getting 'burned'.

Yeah, I understand that. The problem is that if you are running a long term support release, you can't get that dependency unless someone makes a PPA available, and I've not been able to find one for Ubuntu 20.04. All the repos only have 0.28.4 versions for Ubuntu 20.04.
