[Rd] shlib problems with Intel compiler

Hi Martyn,

Thanks for your insight, that seems pretty direct.  Unfortunately, I did not compile this version of R (it's on a large supercomputer system and this version of R was installed by the admins).  Using "R CMD config", I see the following relevant settings:

DYLIB_LD = icc -std=gnu99
DYLIB_LDFLAGS = -shared -openmp
LDFLAGS = -L/opt/compilers/intel/cce/9.1.039/lib -L/opt/compilers/intel/fce/9.1.033/lib -L/usr/local/lib64
SHLIB_LD = icc -std=gnu99

It looks like the SHLIB_CXXLDFLAGS is missing the "-shared -lR -L<loc-of-libR>".  It's a mystery to me how R was built and configured such that it has incomplete/incorrect flags.

By trial and error I figured out how to use a .R/Makevars setting to add the required flags to SHLIB_CXXLDFLAGS.  (It sure would have been useful to have a reference about the syntax and variable names that the Makevars file can contain...is that documented somewhere?)

I wonder if the recommendation for "-lR" is correct.  None of the other packages are compiled with that flag, and everything seems to compile and load OK in R without using that.

Best Regards,
