...cally seeing as that list was called Rcpp. Anyway, I was directed to post my question here. To summarize my current question, I have found two commands that I want to be able to put into a package. The commands are 'R CMD SHLIB X.cc X_main.cc' and 'dyn.load(paste("X",.Platform$dynlib.ext,sep="")),' which I would like to run when my package is installed and maybe have the second command run again when my package is to be used. I've been trying to figure out the documentation and learn through examples, but I'm just not getting it and have been trying for we...

Duncan, I don't know what we want, but it is not a simple matter of documenting what .dynLibs currently does. What I see as bugs are 1) the inconsistent names and types of the components returned by .dynLibs(). 2) the inconsistent inclusion or not of R_X11 in the list returned by .dynLibs(). 3) the inclusion of static info (base) by library.dynam(). 4) including loadable modules...

...ession to load shared libraries. This vector is returned as 'invisible', unless the 'chname' argument is missing. which is clearly no longer true. I don't see why we want loaded modules in there that have nothing to do with packages, or even non-modules. At that point .dynLibs() gave $base DLL name: base Filename: base Dynamic lookup: FALSE $stats DLL name: stats Filename: /usr/local/lib/R/library/stats/libs/stats.so Dynamic lookup: TRUE [[3]] [1] "methods" which seems useless for '.dynLibs' is used for getting or setting the packages that ha...

Good question Rolf. Rui, thanks for pointing out dyn.unload. When I started using Rcpp a couple of years ago I got burned by stale .so enough times that I adopted a policy of recompile-then-start new R session. My workflow does not include Rolf's "brazillion" repeats, so the overhead of this approach has not been too painful. The documentation for dyn.unload (via ?dyn.unload)

...<- 'bitops' pkgpath <- system.file(package=pkgname) library.dynam.unload(pkgname, pkgpath) Some R packages have shared libraries with names that differ from the package, and this strategy won't work for them. I'm aware that the NAMESPACE file will have an entry like this: useDynLib(libname) but I don't know how to access this information from within R. Is this possible? Another strategy I've looked at is to get all the directories listed by .dynLibs() and picking out those that contain the path of the package, but I'd prefer not to do it this way if possible, s...

It has default value "-filetype=asm", but has more values, as "-filetype=obj" and "-filetype=dynlib". "obj" is very interesting, but it till not supported :-( My goal is generation of elf-file for my target, where can be placed machine instruction and debug information. It is possible to create own tool to translate assembler file in "obj", but in "llc" som...
