Build R with Intel Compiler
Your and Brian?s guesses were right: the -openmp linker flag was it. It compiles now fine, though I get errors in make check-all and make install: Running a make check-all gives me (with and without flag -ipo) Running examples in 'mgcv-Ex.R? failed ... Loading required package: splines

It seems that it is connected with the MKL. I have in my MKL variable ?-lmkl_gf_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread. It seems that libiomp5 is not linked to correctly.
I uploaded also my config.log to https://gist.github.com/simonsays1980/7359508
Best

I am trying to build R with an Intel Compiler (14.0.3). Has anyone before done it and could give me a hint for the configuration?
I am sourcing the compilervars.sh for Intel and then configure R with
./R-3.0.2/configure OBJC="clang" --enable-R-framework=/usr/local/R/R-intel --x-includes=/usr/X11/include/ --x-libraries=/usr/X11/lib/ --enable-memory-profiling --with-blas="$MKL" --with-lapack
Further Variables are:
CFLAGS=?-O3 -ipo -openmp -xHost?
CXXFLAGS=?-O3 -ipo -openmp -xHost?
MKL=?-lmkl_gf_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread?!
I get always the same error:

Any clue what this could be?
The above certainly won't work, because you're missing linker flags - I'm pretty sure that you must use -openmp in the linker for it to work, I'm not sure about -ipo -- but doesn't R detect all those automatically? I don't think you should put them in manually. The actual error comes from missing libguide link flags, but they may be implicit if you fix the other problem. Cheers, S
