Dear R Development People:
I was trying to build R-2.12.2 from source on a Windows XP machine.
Doing the make all recommended works fine, but building the bitmap
dll is a problem.
It seems to be in the libpng directory. I got libpng-1.5.1, and
untarred it. However, there is no makefile.mingw file in the
scripts directory.
I then obtained a version of libpng-1.4.5, and the file is there.
The dll file builds fine.
We might want to look at the libpng-1.5.1 directory.
libpng 1.5.1 is not supported for R 2.12.2: it will be for 2.13.0.
The documentation does say so ...
You need libpng, jpeg and libtiff sources (available, e.g., from
http://www.libpng.org/, http://www.ijg.org and
ftp://ftp.remotesensing.org/pub/libtiff/). You will need files
libpng-1.2.18.tar.gz (including ‘1.4.x’ but not ‘1.5.x’),
jpegsrc.v6b.tar.gz, tiff-3.8.0.tar.gz (but not ‘4.0.0beta’) or later.
Thanks for listening,
Sincerely,
Erin
