Thanks for you correction, Dirk. It seems that if I don't care about portability, I could add the absolutely path of the .so files into OBJECTS in Makevars.
For example: ``` ## Use the R_HOME indirection to support installations of multiple R version PKG_LIBS = `$(R_HOME)/bin/Rscript -e "Rcpp:::LdFlags()"` OBJECTS = RcppExports.o rcpp_hello_world.o /home/wush/Test/TestLinking/inst/linkHello.so ``` Is that correct?
