Re: [Rd] Windows 64bit package build requires underscore hack?

I had a problem like this for a while with bigmemory et. al... the check went through to the very end, including successfully building the man pages, then a number of shells popped up and the process died as described here. The build was successful. We never did figure out exactly why, but are fairly sure it was related to our older, overly complicated in our configuration process. This included (among other things which I doubt are related) invoking R from for the purpose of discovering particulars of the platform/environment.

Once we streamlined the configuration process (and avoided calling R from in particular), the problem vanished.

We never had this problem with the use of _ as you report. I'm sure we have many such characters, though perhaps not in exactly the same context.


To be more precise, while the build process worked, the check did not. When it got to the point "* checking for portable compilation flags in Makevars ..."
a number of shells popped up (to run c:\Rtools\sh.exe) and the process died.
