libuv uv__io_poll or uv__poll_io R tolerance, giving me uv polio, help?

["Ian Lambert via cygwin" <cygwin at cygwin dot com>]

Can someone please help with getting libuv to compile, as part of:

$ R CMD /usr/lib/R/bin/INSTALL -l /usr/lib/R/site-library  httpuv_1.3.3[mod].tar.gz

I think I may have stumbled across a bug in the libuv core.c and/or internal.h
source, but I'm not sure. From a search of the maillist, I know libuv may not
be fully compatible, but why not try...

Goal: Install and run R tolerance package on cygwin (or windos).

Roadblocks: 
Corporate approved windos R, version 3.1.1 (2014-07-10) -- "Sock it to Me":
   Will not install tolerance package, Error: This is R 3.1.1, package ‘tolerance’ needs >= 3.2.0
Newer downloaded windos R, version 3.4.0 (2017-04-21) -- "You Stupid Darkness"
   Cannot access internet within R (proxy issues as always), so it requires
   downloading and individually installing and loading about 2 dozen other 
   prerequisite packages supporting tolerance. This may be the fall-back.

More details:

In Cygwin, CYGWIN_NT-6.1   2.8.0(0.309/5/3) 2017-04-01 20:47 x86_64 Cygwin

$ R --version
R version 3.4.0 (2017-04-21) -- "You Stupid Darkness"

So, like a good (or bad) cygwin soldier, I've downloaded and done the install
as in the R CMD command above, for the following packages:

config/
crayon/
digest/
evaluate/
highr/
htmltools/
htmlwidgets/
jsonlite/
knitr/
magrittr/
markdown/
mime/
praise/
R6/
Rcpp/
sourcetools/
stringi/
stringr/
testthat/
xtable/
yaml/

However, this still leaves tolerance, which needs rgl, which needs shiny, 
which needs hpuv, and this is where I am stuck.

$ R CMD /usr/lib/R/bin/INSTALL -l /usr/lib/R/site-library  tolerance_1.3.0.tar.gz 
ERROR: dependency ‘rgl’ is not available for package ‘tolerance’

$ R CMD /usr/lib/R/bin/INSTALL -l /usr/lib/R/site-library rgl_0.98.1.tar.gz 
ERROR: dependency ‘shiny’ is not available for package ‘rgl’

$ R CMD /usr/lib/R/bin/INSTALL -l /usr/lib/R/site-library  shiny_1.0.3.tar.gz 
ERROR: dependency ‘httpuv’ is not available for package ‘shiny’


So.....

$ R CMD /usr/lib/R/bin/INSTALL -l /usr/lib/R/site-library  httpuv_1.3.3

     ^


Looking at the source, it seems there may be confusion on ordering of poll and io,
or I don't understand the need for both uv__poll_io and uv__io_poll, but something 
is wrong, and both are currently used:


$ grep -i uv__poll_io *
poll.c:static void uv__poll_io(uv_loop_t* loop, uv__io_t* w, unsigned int events) {
poll.c:  uv__io_init(&handle->io_watcher, uv__poll_io, fd);

$ grep -i uv__io_poll *
core.c:    uv__io_poll(loop, timeout);
internal.h:void uv__io_poll(uv_loop_t* loop, int timeout); /* in milliseconds or -1 */
kqueue.c:void uv__io_poll(uv_loop_t* loop, int timeout) {
linux-core.c:void uv__io_poll(uv_loop_t* loop, int timeout) {
sunos.c:void uv__io_poll(uv_loop_t* loop, int timeout) {


So, I've tried 2 changes, changing uv__io_poll to uv__poll_io, but neither has fixed it:


$ diff core.c /tmp/2nd/httpuv/src/libuv/src/unix/core.c
317c317
<     uv__io_poll(loop, timeout);
---
>     uv__poll_io(loop, timeout);


$ diff core.c /tmp/3rd/httpuv/src/libuv/src/unix/core.c
317c317
<     uv__io_poll(loop, timeout);
---
>     uv__poll_io(loop, timeout);


$ diff internal.h /tmp/3rd/httpuv/src/libuv/src/unix/internal.h 
127c127
< void uv__io_poll(uv_loop_t* loop, int timeout); /* in milliseconds or -1 */
---
> void uv__poll_io(uv_loop_t* loop, int timeout); /* in milliseconds or -1 */



and the latest error is as follows:


$ R CMD /usr/lib/R/bin/INSTALL -l /usr/lib/R/site-library  httpuv_1.3.3y.tar.gz

Is the fix obvious to someone? 

Thanks!
