----------------------------+-----------------------------------------------
== Build environment ==
* Sage 4.3.3.alpha0, which includes R 2.10.1
* Sun Blade 1000 with two 900 MHz UltraSPARC III+ CPUs, 2 GB RAM. (This
is the same sort of processor as 't2', but is a much older machine, though
still quicker than t2 for building Sage!)
* Solaris 10 03/2005 (The first release of Solaris 10).
* gcc 4.4.3 (The latest as I write).
== The problem ==
Someone updated R in Sage, without testing on Solaris. The update caused
several problems on Solaris - the most obvious one being R now needs
iconv, which Sage does not currently include.
However, despite a new standard package for iconv #8191, R would still not
build on Solaris, but failed with:
{{{
Undefined first referenced
symbol in file
uiter_setUTF8 libR.a(util.o)
ucol_strcollIter libR.a(util.o)
ld: fatal: Symbol referencing errors. No output written to R.bin
collect2: ld returned 1 exit status
}}}
== The Solution ==
Several changes were made to R's spkg-install file, to fix not only the
fact R would not build at all, but also some other enhancements. The
updated package can be found at
http://boxen.math.washington.edu/home/kirkby/Solaris-fixes/r-2.10.1.p0/
* Adds the undocumented option
{{{
--without-ICU
}}}
as that allows R to build without the ICU library from http://site.icu-
project.org/ The option was suggested to me in a private email after a
post to r-help <at> r-project.org. The build now shows:
{{{

* Ensures SAGE64 will attempt a 64-bit build on any platform, not just OS
X. (I've not actually built R 64-bit.)
* Removed all references to the option
{{{
--with-iconv=no
}}}
as R '''must''' have iconv now - it is no longer optional. #8191 is an
iconv library.
* Better detection for X support on Solaris. (The previous test would
always indicate R could not be built with X support, despite the fact it
could be). R's configure script should work this out itself, but some
comments in spkg-install suggest this was not working right on a OSX Intel
10.5.1. '''The changes I made will only impact Solaris'''.
* Added some hopefully helpful comments in spkg-install, as I believe
there are still multiple issues in that file - see #8274
== How to test ==
This should have no impact on any platform other than Solaris, though of
course it is useful to test on multiple platforms to be 100% sure.
To test on Solaris 10, one needs access to a SPARC box. Some notes about
how to test on 't2' are given at
http://wiki.sagemath.org/devel/Building-Sage-on-the-T5240-t2
First one needs to add a new standard package for iconv - #8191.
* Get the spkg from http://boxen.math.washington.edu/home/kirkby/new-
packages/iconv/iconv-1.13.1.spkg and place it in $SAGE_ROOT/spkg/standard
* Copy http://trac.sagemath.org/sage_trac/raw-attachment/ticket/8191/deps
to $SAGE_ROOT/spkg/standard/deps
* Copy http://trac.sagemath.org/sage_trac/raw-
attachment/ticket/8191/install to $SAGE_ROOT/spkg/install (This must be
made executable - it will probably lose the execute permission when
downloading)
Once that is all down, typing 'make' should allow R to build, and you
should get:
{{{
Successfully installed r-2.10.1.p0
}}}
