I would be most interested to get a solution for my problem in rJava
install.
R 3.4.2
MacOSx 10.12.6, Sierra
Xcode 9.
If I install the rJava package, I get this error:
#######
install.packages("rJava")

clang does not understand the option -fopenmp
This version of clang comes with xCode 9:
Apple LLVM version 9.0.0 (clang-900.0.37)
Target: x86_64-apple-darwin16.7.0
Thread model: posix
InstalledDir:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
Then I install clang 5.0.0
clang version 5.0.0 (tags/RELEASE_500/final)
Target: x86_64-apple-darwin16.7.0
Thread model: posix
InstalledDir: /usr/local/opt/llvm/bin
This time, the error is:
#######
clang -o libjri.jnilib Rengine.o jri.o Rcallbacks.o Rinit.o globals.o
rjava.o? -dynamiclib -framework JavaVM -fopenmp -L/usr/local/lib

-lz -licucore -lm -liconv
ld: library not found for -lomp
clang-5.0: error: linker command failed with exit code 1 (use -v to
see invocation)

Has someone a solution to compile rJava ?
Thanks
