Dear All,

zlib has been removed from R-devel src/extra recently, and building R
requires zlib >= 1.2.5. Ubuntu 12.04 LTS (also used on Travis CI) only has
1.2.3.

Hmm, 1.2.3 is from July 2005, 1.2.5 from July 2010.

This means that the next version of R will probably not available on Ubuntu

The 'next version of R' will be 3.2.0, and the pre-3.2.0 sources include zlib.

12.04. (Unless I am missing something of course.) Which is probably fine,
it is almost three years old now.

I guess R-core is aware of this. Just wanted to be sure.

Yes, although nothing stops you installing zlib >= 1.2.5 from sources.

The minimal required versions of bzip2, pcre, zlib are all from 2010, and of liblzma from 2011.

Whereas R-devel will not be released (as 3.3.x) until 2016.


Best Regads,
Gabor
