I've been developing a package called foobar for a couple of years now.
It has evolved through various versions, but has always contained
compiled C code. Recently, R CMD check has started generating the
following message
[START QUOTE]
R CMD check foobar_1.7.5.tar.gz
* using log directory ‘/home/david/foobar/package/foobar.Rcheck’
* using R version 2.15.2 (2012-10-26)

* using session charset: UTF-8
* checking for file ‘foobar/DESCRIPTION’ ... OK
[LOTS OF '...OK' CHECK REPORTS REMOVED FOR BREVITY]

Found ‘puts’, possibly from ‘printf’ (C), ‘puts’ (C)
Object: ‘foobar.o’
Compiled code should not call functions which might terminate R nor
write to stdout/stderr instead of to the console.
See ‘Writing portable packages’ in the ‘Writing R Extensions’ manual.

NOTE: There was 1 note.
See ‘/home/david/foobar/package/foobar.Rcheck/00check.log’ for details.

This message is recent, but appears even when I re-compile and check old
versions of the package which previously passed the check without any
such warning messages.
My understanding is that since R 2.15.0 R CMD check has undergone
numerous modifications, and as a result it is now identifying a
"problem" that wasn't being identified previously. I'm currently running
R 2.15.2.
Identifying the source of the message is a non-trivial problem because
there are a large number of calls to printf and fprintf etc in several
thousands of lines of code spread over many different *.c files.
So my question... is there a way to obtain a more verbose output that
could point me to the lines of code that generate the message? Without
this information debugging is rendered unnecessarily hard, time
consuming and frustrating.
many thanks
David
