[R-pkg-devel] Does win-builder restrict where binaries can be downloaded from?

[Jialin Ma]

Dear all,

I have the following error on win-builder, which says the url from
anaconda.org can not be opened. The url is valid, does win-builder
restrict the domain where binaries can be downloaded? I have previously
tried download from github, where it works.

* installing *source* package 'symengine' ...
** libs

*** arch - i386
rm -f interface.o symengine.dll 
"D:/RCompile/recent/R/bin/i386/Rscript.exe" "../tools/winlibs.R"
