Error: must pass a package name, “DLLInfo” or “DllInfoReference” object

[pat-s]

The recent v6.1.1 update causes the following error on Travis:

Error: must pass a package name, “DLLInfo” or “DllInfoReference” object

The error does not appear with v6.1.0. Also it just appeared today after v6.1.1 was released on CRAN.

Using devtools::document(".") works in some instances. I think this could be related to the change made in #704?

The problem is this commit: dynamic libraries are not compiled, even if they don't exist. It should probably be compile = NA instead of compile = FALSE.

[pat-s]

In the mean time I'll just do a remotes::install_version("roxygen2", "6.1.0") before the problematic call.

It definitely shouldn't be compile = NA because that would return it to the previous behaviour that people complained about.

[mb706]

Maybe you could make load_all skip load_dll and hope that loading the package never ends up calling a compiled function (should be rare enough, this is the old behaviour?). Otherwise (as I understand it) roxygenise() will just not work when no compiled dlls are present, and #771 is back where it started: compilation is necessary before documentation, only now it needs to be invoked explicitly.

[hadley]

My expectation is that most people are documenting after a load_all() so this should rarely be a problem. The root cause of this issue was fixed upstream in pkgdown: deployment your package website shouldn't trigger a re-roxygenise.

I agree that it would be nice if pkgload failed more gracefully if compile = FALSE and no dll is present.

[mb706]

I think #771 & #776, or people like them, would be happiest if documentation could be created without the necessity to build dlls at all, whether done by roxygenise() itself or required to do manually. I guess manual means one can skip the build process when git checkout changes source files and compile = NA would recompile unnecessarily in this case.

[eddelbuettel]

This is clearly a continuation of #771 which I filed months ago, and which was closed 17 days ago.

It is however not fixed. So I have to continue to use version 6.0.1 which to me is the last non-borked one for the sole use case I have here. Which is creating Rd files from R files. Which is what this package was about at some point.

[krlmlr]

With some changes to pkgload it might be possible to load only the R code but never the DLL.?

[hadley]

This is a continuation of #784, where I asked for help testing the feature, and no one responded. Obviously, roxygen2 works just fine for me, so I need help from the community.

@krlmlr that would seem to me to be a weird abuse of pkgload. It shouldn't create simulated packages that can't work. I think the approach that you outline in
#771 (comment) is a better one.
