trouble with R CMD INSTALL for building my own library

Jonathan Li writes:

Hi,

I have built a library that consists of a piece of C code and some R
functions.  To build it into a library that I can load using library()
command, I have followed "Writing R Extensions" and made
sub-directories such as mylib/R and mylib/src.

It actually is 'package' and not 'library'.

But when I run R CMD INSTALL mylib, nothing seems to be happening with
src directory, i.e., no C compiling. I have probably missed some key
steps. But after reading very carefully "Writing R Extension", I
conclude that I don't need to write my own Makefile in src since R CMD
INSTALL will use the default in /usr/lib/R/etc/Makeconf Here is a copy
of Makeconf file. In addition, R CMD check and R CMD build all ran
without running "make". Is this the way it is supposed to be?  (no
error messages encountered).

Sounds strange.  You really have

        mylib/src/foo.c

(note the extension!) and nothing happens?

-k

Yes. I actually made an extra dummy c file called foo.c in mylib/src :)
still nothing happens.
Here are more messages when running R CMD check/install/build

$R CMD check mylib

After becoming super user, I ran

$R CMD INSTALL boosttree
Installing binary package `mylib' ...
 DONE (boosttree)
 
DONE (INSTALL)

As you can see, R CMD build tries to "clearning src". I am not sure if
this means that something went wrong in my
setup. 

Thanks plenty again for any insights!
