[R] Issue building from source on RHEL7

[Stéphane Plaisance]

Thanks Ivan,

The instruction on Posit are almost identical to those in R except they add a version folder to be able to instyall multiple R's in parallel. I do not think this is the reason.

I apparently fixed my 4.1.3 issue by adding a symlink R in /usr/lib64/ pointing to /opt/R/${R_VERSION}/lib64/R folder
This additional symlink is not detailed in the doc(s) and apparently takes care of re-establishing the link to lib and source files when running R.

I now do not have errors anymore and it even works inside RStudio

Thanks a lot for your help, hoep this can help others with the same issue.

    The official installation manual can be found at
    <https://cran.r-project.org/doc/manuals/r-release/R-admin.html>, not at
    the Posit website.

    This should have worked. In fact, I cannot reproduce your problem on my
    own: with the same command line, R passes the check and runs both from
    the build directory as ./bin/R and (after a `make install`) from the
    prefix I specified.

    Something about remembering the prefix must have gone horribly wrong,
    making your build of R confused enough to go looking for its files in
    the wrong directory. Do you have any lingering R-related environment
    variables set? Does `env | grep R` show anything useful? Is there
    anything useful about the prefix in config.log? Do the generated files
    src/scripts/R.fe and bin/R contain the right value of the R_HOME_DIR
    variable?

    When you compose your messages in HTML, we only get the plain text
    version automatically generated by your mailer. This transformation is
    sometimes lossy:
