Would be nicer if stop
could be installed only once, instead of once per function, but that's an improvement I guess.

@jjallaire would it make some sense to have something like :
SEXP stop_symbol() {
static SEXP s = Rf_install("stop");
return s;
}
somewhere at the top of the generated RcppExports.cpp
so that the stop
symbol is only installed once, instead of once per function ?

You might also need to make this function static in order to support unloading DLLs on certain platforms. This is not important for packages but is important for sourceCpp()
. IIRC, it caches dynlibs and those can be unloaded and reloaded several times in the same R session. On certain platforms, the ctors for the static variables failed to be called when the dynlib was loaded again, even though the dtors did get called on unloading, which caused crashes. I fixed this by giving static scope to the functions wrapping the static variables.

This never gets called, but it might quiet rchk

FWIW, this seems to have removed the There is still a lot of noise, some of which is dealt with in #947 |
Thanks for the update. A reverse depends check is running, but I do not have very good resources for those now (maybe a company like RStudio would like to help there, hint, hint, ...) so it will take a moment. |
@eddelbuettel at some point we probably should talk more about doing revdep on the Illinois Campus Cluster (ICC) with |
