Hi,

I have some CEL files which I am unable read with the release version of
the affy package (using ReadAffy()), so I thought it would be worthwhile
trying the devel version.  I currently only have access to Windows and
I'm trying to build affyio (required by affy), but I'm having trouble
with zlib etc. 

I downloaded the zlib libraries and header files from
http://ftp.uni-kl.de/pub/windows/cygwin/release/mingw/mingw-zlib/ (the
first hit from Googling "mingw zlib") and copied them into the mingw lib
and include directories.  But I am getting the following errors:

gcc  -shared -s  -o affyio.dll affyio.def read_abatch.o read_bpmap.o
read_cdf_xda.o read_cdffile2.o affyio_res.o  -L
C:/PROGRA~1/R/R-24~1.0DE/bin   -lR
read_abatch.o:read_abatch.c:(.text+0x12f5): undefined reference to
`gzgets'
read_abatch.o:read_abatch.c:(.text+0x1335): undefined reference to
`gzopen'
read_abatch.o:read_abatch.c:(.text+0x136b): undefined reference to
`gzrewind'
read_abatch.o:read_abatch.c:(.text+0x159c): undefined reference to
`gzclose'

etc.

I'm using 
R version 2.4.0 Under development (unstable) (2006-05-05 r37982)
affyio_1.0.0
affy_1.10.0

Any suggestions would be greatly appreciated.  

Thanks,
James
