R devel - Dec 2001 - trouble with R CMD INSTALL for building my own library

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. 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).

Where is the problem? Thanks in advance!

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

Sounds strange.  You really have

	mylib/src/foo.c

(note the extension!) and nothing happens?

Hi all,

Problem solved!

Thanks to a suggestion by Robert Gentleman, I realized that there may be
something that makes R think that mylib is a binary rather than source
package. I downloaded Brian Ripley's tree source package and basically
copied each directory. As it turns out, I have not put in a mylib/man
subdirectory (I thought I could add it any time later.) and R was then
tricked to believe that mylib is a binary! Once I add an empty mylib/man
subdirectory, things become normal with compiling etc. Timothy, I think that
your problem is likely to be the same source then. 

Regards,
Jonathan

Jonathan:

In that case, does not R CMD INSTALL start by saying
"Installing binary package ..."?
