Subject: [Rd] Setting the path to Rtools for package compilation on Windows
Message-ID: <CA+hbrhVN1ngZiyVH2q2Z+rOMeLhGZ88eQu4c04unkVDo7zkugw@mail.gmail.com>

Hi all,

I'm trying to set up the Windows Rtools toolset for building packages
with compiled code. I installed for Windows R-3.4.3 from CRAN and
installed Rtools-3.4 in a custom location M:\R\R-3.4.3 and
M:\R\Rtools-3.4

Following the instructions, in shell, I set
Path=M:\R\Rtools-3.4\bin;M:\R\Rtools-3.4\gcc-4.6.3\bin;M:\R\R-3.4.3\bin;...
(the ... are other paths irrelevant for R/Rtools).

When I run

M:\Work\RLibs>R.exe CMD INSTALL --build WGCNA

I get the following ouput:

In R CMD INSTALL
* installing to library 'M:/R/R-3.4.3/library'
* installing *source* package 'WGCNA' ...
** libs

*** arch - i386

Apparently the install is looking for Rtools in c:\Rtools. I am a
perpetual Windows newbie and would be really thankful for any pointers
as to how to proceed.
