I looked at an example from the Makefiles clang/tools, and the final 
command line was

clang++ `llvm-config --ldflags` main.o  -lclangFrontendTool 
-lclangFrontend -lclangDriver -lclangSerialization -lclangCodeGen 
-lclangParse -lclangSema -lclangStaticAnalyzerFrontend 
-lclangStaticAnalyzerCheckers -lclangStaticAnalyzerCore -lclangAnalysis 
-lclangARCMigrate -lclangRewriteFrontend -lclangRewriteCore -lclangEdit 
-lclangAST -lclangLex -lclangBasic `llvm-config --libs`

Now it compiles :)

Such a silly mistake, but I appreciate your response, it made me see my 
mistake.

Thanks!
