Build fails with undefined reference to uv__io_poll in core.c:317 (Cygwin, Windows 7) about httpuv HOT 3 CLOSED

Shoot, I really don't know. We have a branch that uses 1.8.0 but I don't think it will work on cygwin as it's built on mingw. Is there a reason you have to use the cygwin version of R? I would expect a lot of packages with C/C++ code would have trouble with cygwin, as I don't think many package authors test against it.

Is there a reason you have to use the cygwin version of R?

All I need is a command line version of R to follow/repeat a published example application, and then expand to different data. The main R library/package needed is tolerance, and a couple others. Tolerance requires R version >=3.2.0, and several other packages including rgl, shiny, httpuv and thus libuv; however, it seems no fancy output is really needed. Because of network restrictions here, the add-on packages have to be separately downloaded with a browser or equivalent, and manually installed from local files. It took 45 packages, plus download of R version 3.4 to get it to work under Windows.

I'd rather use Linux, but available Linux machines here have only R 3.1.2, which is too old, and getting it upgraded is a hurdle.

Cygwin comes with R version 3.4.0 now, which is good. R has been a standard package in Cygwin since version 2.14.1.

If a lot of hoop jumping is required either way - Windows or Cygwin, then my preference is to do it under Cygwin, because I'm already using it for other things like X-windows displays, ssh, bash scripts, editing, etc.

I would expect a lot of packages with C/C++ code would have trouble with cygwin, as I don't think many package authors test against it.

I'm no expert, but so far, 20+ packages installed just fine in Cygwin, until libuv.

Is this error worse than it looks to the untrained eye?

In function uv_run: ...core.c:317: undefined reference to uv__io_poll

I believe this should be fixed by #121. If it is still a problem, please re-open or file a new issue.
