I ran into this "maximal number of DLLs reached" issue recently because my app requires importing many other packages.

...certain problems can arise based on the compiler used and that these problems can sometimes cause R not to be able to access everything appropriately, but I've not found how to fix any of these problems. Specifically, after using dyn.load, I know the dll has been loaded because it is listed in getLoadedDLLs(), but when I try is.loaded("subroutine name"), it returns FALSE. I saw that this was mentioned in the manual, but it too offers little help for a solution. Any advice would be greatly appreciated.

...ble *x). The function is declared void, the output value is one of the arguments. C calling sequence is used. When inspecting the exports of the DLL with dumpbin I can see that the function I need is exported under the name 'planckwR'. Loading the DLL with dyn.load(dllpath). Works fine. getLoadedDLLs() shows info on the 'Planck.dll' that I made. So far so good. Made a function i R like this: Planckw<-function(Temp) { wavelength<-0.0 .C('planckwR',as.double(Temp),as.double(wavelength)) return(wavelength) } Calling this function, R complains the function...

However, when invoking the function, xplusy(1, 2), R complains: Error in .C("foo", as.double(x), as.double(y), out = double(1)): C symbol name "foo" not in load table I found some hints concerning Fortran code producing this error message, but no help concerning C code...

This is a request to increase MAX_NUM_DLLS in Rdynload.c in from 100 to 500. On line 131 of Rdynload.c, changing #define MAX_NUM_DLLS 100 to #define MAX_NUM_DLLS 500 In development of the mlr package, there have been several episodes in the past where we have had to break up unit tests because of the "maximum number of DLLs reached" error. This error has been an inconvenience that

Hi R-devel, I'm trying to get R 3.2.1 working on Haiku (an open source OS inspired by BeOS, not Linux based) on i586. With a few small changes to library paths and ifdefs I am able to get a seemingly working R binary. The build process stops with the 'tools' package. The last lines from make are below. Does anyone have any tips? I'm rather new to debugging at this low level. Are

Hello, My problem is that I hit the hard-coded MAX_NUM_DLLS (100) limit of the number of loaded DLLs. I have a number of custom packages which interface and integrate a lot of CRAN and Bioconductor packages. For example, on my installation: Rscript -e 'library(crlmm);print(length(getLoadedDLLs()))' gives 28 loaded DLLs. I am currently trying to work-around that by putting external packages in Suggests: instead of Imports:, and lazy-load them, but still I am wondering if that threshold value of 100 is still relevant nowadays, or would it be possible to increase it. Thanks, Karl F...

...being unloaded themselves. In other words, there may be left-over DLLs just sitting there doing nothing but occupying space. You can remove these, using: R.utils::gcDLLs() Maybe that will help you get through your tests (as long as you're unloading packages). gcDLLs() will look at base::getLoadedDLLs() and its content and compare to loadedNamespaces() and unregister any "stray" DLLs that remain after corresponding packages have been unloaded. I think it would be useful if R CMD check would also check that DLLs are unregistered when a package is unloaded (https://github.com/HenrikBe...
