I successfully did the following recently in order to build 64 bit PL/R on Windows 7: ---------------- dumpbin /exports R.dll > R.dump.csv Note that I used the csv extension so OpenOffice would import the file into a spreadsheet conveniently. Edit R.dump.csv to produce a one column file of symbols called R.def. Add the following two lines to the top of the file: LIBRARY R EXPORTS Then run the following using R.def lib /def:R.def /out:R.lib ---------------- HTH, Joe -- Joe Conway credativ LLC: http://www.credativ.us Linux, PostgreSQL, and general Open Source Training, Service, Consulting, & 24x7 Support
