[Rd] using zlib in a package: problems in windows

[Ramon Diaz-Uriarte]

Dear All,

I am having trouble getting an R package to build and install
correctly under Windows. In this package, which builds and checks OK
under Linux, I use zlib (among other functions, gzprintf).

As mentioned by Prof. Ripley a while back, the file "CHANGES" under
src/gnuwin32 says explains that to, to use zlib, one has to set
$(ZLIB_LIBS) in PKG_LIBS. I have a Makefile.win with just that.

I have also downloaded the Windows toolset (Rtools.exe) which I have
used to successfully build R-patched. However, I still cannot get the
package to compile.

>From the log, it seems that in fact the build is trying to use zlib,
but the gzprintf symbol is not found. However, gzprintf is in the
zlib.h header.  00install.out follows below.

What am I doing wrong?

Thanks,

R.

P.D. I am using Windows 2000 (under vmware).
