[Rcpp-devel] libRInside.a and "base package"

[Dirk Eddelbuettel]

Dan,

Trying to help here but I'm not a windows user...

Confirmed. I would have to look into the build recipe of why we only have one

Last time I was working on / overhauling / windows, I did use 32 and 64 bit
and it just worked.  That said, right now I am at home where I only have a
puny virtual win32 instance.

Now, as I recall, both 'just worked'.

I have seen that one before, it should not happen, but I believe it to be an
incomplete "setup". I may have been able to overcome this by defining RHOME.

I just tried on the small, slow virtual instance, and I got linking errors
with the i386 version of libRInside.a.  Sorry.

I'll try to have a look next week at work on the more powerful win7 / 64bit desktop.
In the meantime, maybe someone else can walk you through basic steps...

Dirk
