RSRuby?

Ruby
1

Hello,
I was hoping someone here can help me with an install of Rsruby. I
have it installed on one box but have been having trouble on my
other. My R libraries are installed in /usr/local/lib64/R/

the mkmf file is as follows. I think it is a linking issue that I
thought would have been solved by export R_HOME=/usr/local/lib64/R/
lib . Is there a way I should link the entire directory?

Thank you for your time,
Michael

Hi,

What did you use to install R? From source or packages?

I assume you have libRblas.so in your /usr/local/lib64/R/lib
directory, so did you put /usr/local/lib64/R/lib into LD_LIBRARY_PATH
or ld.so.conf?

I installed R from source. You are right on that file. I ran this
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib64/R

I also added /usr/local/lib64/R/lib
to ld.so.conf and ran ldconfig.

Thank you for your help.
Michael

Actually, I think there may be an issue with the environment
variable. after I use export, nothing is added to /etc/environment.
Could this be it?

Thank you again for the help,
Michael
