Hi! I'm having trouble installing Rpy2. This question is also on stackoverflow:
http://stackoverflow.com/questions/30921570/rpy2-cant-find-my-r-libraries-on-install?noredirect=1#comment49893728_30921570 R built from source, installed locally. R is at ~/bin/R (which is in my PATH) and its libraries are in ~/lib64/R/. Installing rpy2 should be simple. It finds the correct R just fine (as it's in the path). Then it can't find the libraries. $python setup.py build install R version 3.2.1 (2015-06-18) -- "World-Famous Astronaut" ... setup.py:211: UserWarning: No include specified warnings.warn('No include specified') setup.py:222: UserWarning: No libraries as -l arguments to the compiler. warnings.warn('No libraries as -l arguments to the compiler.') Compilation parameters for rpy2's C components: include_dirs = [] library_dirs = [] libraries = [] extra_link_args = [] And then we get a million errors that it can't find functions that are in the R libraries. Rpy2's documentation says <http://rpy.sourceforge.net/rpy2/doc-dev/html/overview.html> there's a simple option for designating where R or its libraries are: python setup.py build --r-home ~/lib64/R/lib install But if you do this, then you get: setup.py:222: UserWarning: No libraries as -l arguments to the compiler. warnings.warn('No libraries as -l arguments to the compiler.') Compilation parameters for rpy2's C components: include_dirs = [] library_dirs = [] libraries = [] extra_link_args = [] usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...] or: setup.py --help [cmd1 cmd2 ...] or: setup.py --help-commands or: setup.py cmd --help error: option --r-home not recognized It looks like the --r-home functionality has been removed. How does one point rpy2 to the correct libraries?
