[Rd] Calling Rscript from Makevars

[Martyn Byng]

Hi,

I am trying to package some code to use with R and wanted to call
Rscript from within the Makevars file (I am trying to automate the
setting of the location of a third party library depending on what is
available / the system the package is being installed on).

If I just have a simple Makevars containing


PKG_LIBS= -lnag_nag -L/fserver/nagprod/FL22/fll6a22df/lib


the package is built without any errors, if I attempt to add a call to
Rscript, for example (which I think is the way that "Writing R
Extensions" recommends):


R_SCRIPT_NAME=Rscript
ifneq ($(R_HOME),)
  R_SCRIPT=$(R_HOME)/bin$(R_ARCH_BIN)/$(R_SCRIPT_NAME)
else
  R_SCRIPT=$(R_SCRIPT_NAME)
endif
R_ARCH=$(shell $(R_SCRIPT) -e 'cat(R.version$$arch)')

PKG_LIBS= -lnag_nag -L/fserver/nagprod/FL22/fll6a22df/lib


I get the following error:

* checking for file 'NAGFWrappers/DESCRIPTION' ... OK
* preparing 'NAGFWrappers':
* checking DESCRIPTION meta-information ... OK
* cleaning src
make: Nothing to be done for `clean'.
* removing junk files

Stop.
ERROR: compilation failed for package 'NAGFWrappers'

Any help / pointers would be appreciated.

Cheers

Martyn
