When I try to install devtools in R via RStudio Server on my Red Hat Linux machine it fails because it cannot install git2r. When I then try to install git2r, it fails to install.
I think it might be because I need to install libssh2 on my Linux machine based on the following warning. Is that correct? If so, that could be corrected with a yum install libssh2-devel from the Linux command line, correct? Unfortunately, I'm waiting on my admin to give me sudo privileges, so I can't test that hypothesis yet.
configure: WARNING:
---------------------------------------------
Unable to find the LibSSH2 library on this
system. Building a version without support
for SSH transport.
To build with SSH support, please install:
libssh2-1-dev (package on e.g. Debian and Ubuntu)
libssh2-devel (package on e.g. Fedora, CentOS and RHEL)
libssh2 (Homebrew package on OS X)
and try again.
If the LibSSH2 library is installed on
your system but the git2r configuration
is unable to find it, you can specify
the include and lib path to LibSSH2 with:
R CMD INSTALL git2r --configure-vars='LIBS=-L/path/to/libs CPPFLAGS=-I/path/to/headers'
---------------------------------------------
There is also a warning at the end of the failed install output that mentions libssl. Is that related to libssh2 or a separate issue? If separate, how would I fix it? Is there a libssl library I should install or something?
