Description Benda Xu gentoo-dev 2011-01-17 14:38:14 UTC
R has a design flaw using /usr/bin/R as a shell wrapper hardcoding LD_LIBRARY_PATH envs. People has already pointed it out[1], but upstream insists on such a non-standard solution.

This dirty ad-hoc implementation may cause problems if undesired libraries on LD_LIBRARY_PATH (silently) get loaded in front of gentoo standard ones.

One such senario is in Gentoo Prefix. We want to use libraries in ${PREFIX}/usr/lib, but R sets /usr/local/lib:/usr/X11R6/lib to LD_LIBRARY_PATH causing errors on the old (host) systems.

Reproducible: Always

Steps to Reproduce:
1. touch /usr/local/lib/libXrender.so
2. R
3. in R env type "X11()"
Actual Results:  
Error in X11() : X11 module cannot be loaded
In addition: Warning message:
In X11() :
  unable to load shared library '/usr/lib/R/modules//R_X11.so':
  /usr/lib/libcairo.so.2: undefined symbol: XRenderCreateLinearGradient


Expected Results:  
X11() loads successfully.

in the example libcairo.so looks for libXrender.so for symbol XRenderCreateLinearGradient.
