Hi, I am trying to compile a package, in which C code is used. When I was checking the package with the dll file under the sub-folder "SRC", a WARNING msg was returned: "Source packages should not contain undeclared executable files." When I exclued it from the folder, I got an ERROR msg: Error in library.dynam(lib, package, package.lib) : DLL 'Cs2g' not found: maybe not installed for this architecture? Anyone knows how to solve this problem? Sorry for this naive question but I am really confused. Many thanks. Best regards, Binbin [[alternative HTML version deleted]]

I see two cases here:
Case 1: You intend to upload this package to CRAN
--> Don't include the dll in the first place. See 'Writing R
Extensions' for details.
Case 2: You only plan to do use this locally.
--> Learn more about package builds. See 'Writing R
Extensions' for
details, as well as 'R CMD INSTALL --help' and pay
attention to
single architecture builds.
The Visual Studio tool chain is not officially supported by R,
so you are unlikely to get specific help. You mix this, but it
is an advanced topic, and it is somewhat outside the supported
range of endeavours with R, you are on your own.
Google for 'mixing MinGW gcc and Visual Studio' and other
topics.
Good luck, Dirk
