I’m trying to install RStan using the instructions provided here:

But when I try to execute the code in the final verification step:
Verify that your toolchain works by executing the code below in R and checking that it returns the value 10:
fx ← inline::cxxfunction( signature(x = “integer”, y = “numeric” ) , ’
return ScalarReal( INTEGER(x)[0] * REAL(y)[0] ) ;
’ )
fx( 2L, 5 ) # should be 10

And I get the following error:

fx ← inline::cxxfunction( signature(x = “integer”, y = “numeric” ) , ’

  •     return ScalarReal( INTEGER(x)[0] * REAL(y)[0] ) ;
    
  • ’ )
    g++.exe: error: unrecognized command line option ‘-03’

Not sure what I did incorrectly. Any help is much appreciated!

In the file given by

file.path(Sys.getenv("HOME"), ".R/Makevars")))

there is a

CXXFLAGS += ~O3 ...

where ~ is some misencoding of a dash. It should be a dash, followed by the capital letter 0 followed by the number 3 without spaces in between, like

CXXFLAGS += -O3 ...

Wow. Thanks so much.
