Not able to install git2r

General

Hi,

Has anyone had this issue with installing git2r on RHEL 8? I have libgit2-devel already installed. Thank you.

'install.packages("./git2r_0.35.0.tar.gz", type="source", configure.vars="LIB_DIR=-L/usr/lib64 INCLUDE_DIR=-I/usr/include")'
inferring 'repos = NULL' from 'pkgs'

  • installing source package ‘git2r’ ...

    Configuration failed to find libgit2 library. Try installing:

    • brew: libgit2 (MacOS)
    • deb: libgit2-dev (Debian, Ubuntu, etc)
    • rpm: libgit2-devel (Fedora, CentOS, RHEL)
      and try again.

    If the libgit2 library is installed on your system but the git2r
    configuration is unable to find it, you can specify the include and
    lib path to libgit2 with:

    given you downloaded a tar-gz archive:
    R CMD INSTALL git2r-.tar.gz --configure-vars='INCLUDE_DIR=/path/to/include LIB_DIR=/path/to/lib'

    or cloned the GitHub git2r repository into a directory:
    R CMD INSTALL git2r/ --configure-vars='INCLUDE_DIR=/path/to/include LIB_DIR=/path/to/lib'

    or download and install git2r in R using
    install.packages('git2r', type='source', configure.vars='LIB_DIR=-L/path/to/libs INCLUDE_DIR=-I/path/to/headers')

configure: error: in '/tmp/Rtmpyj1je2/R.INSTALL25c4e746d89c9d/git2r':

You are missing this system dependency, try installing it with this command from a system terminal

yum install libgit2-devel

Possibly you need a newer version of libgit2-devel, AFAIR you can install one from EPEL.

Also, try to make your install.packages() command as simple as possible, it is not necessary to set LIB_DIR and INCLUDE_DIR unless you run into some issues. Even worse, setting LIB_DIR and INCLUDE_DIR will prevent pkg-config to figure out where the libraries and header files are located...

I'd try and run

install.packages("./git2r_0.35.0.tar.gz", type="source")

and see if this works (provided you have downloaded git2r_0.35.0.tar.gzinto the current folder). If you system allows direct download of packages from CRAN, I would even go as far and simply run install.packages("git2r").

I definitely can confirm that on RHEL8 with the provided libgit2-devel package I am able to successfully install git2r from source:

Thanks, but I've already done that as I mentioned in my post

I tried that as well. Same error

Thanks! I'll give that a try.

This issue is resolved by installing a newer version of libgit2-devel from EPEL. Thanks, all!
