Hi Martin, I wrote a detailed example to a similar question on R-help. It can be viewed at: http://r.789695.n4.nabble.com/Writing-own-simulation-function-in-C-td1580190.html#a1580423 The source code mentioned in the post can be obtained from: http://gist.github.com/323498 The example was for C and not C++, but maybe it can help you get the package building correctly. Basically: 1) Write your C functions and put them in the /src directory of the package. 2) Write R wrappers for the C functions and put them in the /R directory along with a zzz.R that includes a .First.Lib() which calls library.dynam(). With these requirements satisfied both R CMD INSTALL and R CMD build --binary should be able to produce working packages. Example files that satisfy the points above are included in the source code I linked to. Hope this helps! -Charlie ----- Charlie Sharpsteen Undergraduate-- Environmental Resources Engineering Humboldt State University -- View this message in context: http://r.789695.n4.nabble.com/including-DLL-in-a-package-tp2336420p2336992.html Sent from the R devel mailing list archive at Nabble.com. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
