Fail to call AC_CACHE_CHECK on R 2.7.0 for Solaris
Prof Brian Ripley wrote:
This is covered in the 'R Installation and Administration' manual that
INSTALL asked you to read. Specifically for Solaris:
Modern Solaris systems allow a large selection of Open Source software
to be installed via @command{pkg-get}: a Sparc Solaris 10 system came
with @code{libreadline} and @code{libiconv} and a choice of @code{gcc3}
and @code{gcc4} compilers, installed under @file{/opt/csw}. (You will
need GNU @code{libiconv}: the Solaris version of @code{iconv} is not
sufficiently powerful.)
R 2.7.0 is documented to build on several versions of Solaris in that
manual, so the problem is definitely not 'R on Solaris'.
You analysis is plain wrong. Search for r_cv_iconv_latin1 in
configure and you will see three lines which set it (plus one that
checks if it was set in the cache).
Thanks a lot. Clearly when I compiled R directly, it see my GNU libiconv rather than the Sun supplied one, but when built as part of Sage, it see the Sun one. That should be easy to fix. Dave
