[Rd] Rcmd build 32bit-only package on win7 64 bit platform?

2010-10-18 Thread Hans-Peter Suter 
Is it possible to suppress compiling for the x64 arch when doing 'Rcmd
build ? Such that the pre-compiled package for binary
distribution only contains a 'lib/i386/mypkg.dll'.

For CHECK (and also INSTALL) there is a '--no-multiarch' argument, but
I didn't find something similar for build.

Otherwise, I suppose, I could
- handle the problem in Makevars or Makefile or
- build the shlib manually and put it at the correct place or
- provide a placeholder library with C (my code is Delphi, 64bit
should/will come next year)
- (build inside a XP32bit VM)

Are there any other packages which are 32bit only (for now)?

Thanks for any advise,
Hans-Peter

[Rd] Possible bug with scrambled messages on Win7-64bit using R2.12.0 (32/64 bit version)

2010-10-25 Thread Hans-Peter Suter 
When executing 'dyn.load("this/dll/does/not/exist.dll")' the resulting
error message is scrambled. Not all characters will be displayed and
when I select the empty region text disappears/reappears.

For a screenshot see:
http://dl.dropbox.com/u/2602516/dyn.load_error1.PNG and
http://dl.dropbox.com/u/2602516/dyn.load_error2.PNG.

Note: I had the same problem with xlsReadWrite startup messages with
R2.12.0. The solution was to replace my 'CRLF' (windows) line endings
with 'LF' (unix). While debugging the issue, I noticed that the
problem only occurs on my Win7-64bit platform but not on WinXP-32bit.

Cheers,
Hans-Peter
