In order to build this module you need to build the source for R. I have been using R version 1.3 but I think anything above 1.2 is probably ok. Source for R can be obtained at www.r-project.org Steps To Build -------------- 0. Build & install PDL::NamedArgs 1. Build R (ie. ./configure; make) 2. Build R nmath standalone cd cd src/nmath/standalone make 3. Edit the Makefile.PL to set the Rlocation variable to the path to the R source code root. 4. perl Makefile.PL 5. make 6. perl testPDL.pl 7. make install 8. Have fun.... --John Cavanaugh (cavanaug@users.sourceforge.net)
