I'm building my own Rcpp Package (name: RUtilities) on Mac. However, I encountered the following error when executing devtools::document()

** checking absolute paths in shared objects and dynamic libraries
─  DONE (RUtilities)
Error in dyn.load(dll_copy_file) : 
  unable to load shared object '/var/folders/70/0x058vd10ts57r4ck5j2j3s00000gn/T//RtmpIXnrlU/pkgload13d793cdb33ea/RUtilities.so':
  dlopen(/var/folders/70/0x058vd10ts57r4ck5j2j3s00000gn/T//RtmpIXnrlU/pkgload13d793cdb33ea/RUtilities.so, 0x0006): symbol not found in flat namespace '__RUtilities_test'

My current attempts:

1. delete the .so, .o files in the src folder and rerun the code.
2. delete the RUtilities.so file in the /var/folders/70/ folder.

However, the error persists.

This problem is very strange to me, because the same package can be installed correctly on my Linux server.

I suspect there is something wrong with the R version, since my Linux server uses R3.6, while my mac uses R4.1. Should I modify the Makevars file when the R version changes? My Makevars file looks like this right now:

PKG_LIBS = $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)
PKG_CPPFLAGS = -I../inst/include/


CXX_STD = CXX11
PKG_LIBS += $(shell ${R_HOME}/bin/Rscript -e "RcppParallel::RcppParallelLibs()")

Also, my Mac uses the Apple M1 chip. Is this chip the problem?

Any suggestions are welcomed! Thanks!
