If you read my email carefully then: if I wrote Cairo I mean the R
Package Cairo else I mean the Library cairo from carographics.org!
I need to use Cairo because we are creating a huge amount of graphics
in BATCH mode for reporting purpose. I think pango is not the solution I
need for this but I could be wrong.
The matter to upgrade from R 2.7 to 2.12 on our production system is we
need more/other Database packages that we used before.

First, it is 'Cairo' (R is case sensitive), and this is wrong list
(see the posting guide).
But in any case we can't help you as what you show is far from
complete and this is not an R issue. Usually there are multiple
versions of such libraries on a Solaris system: the problem is most
likely the library paths. Please ask your local Solaris help for
assistance in sorting out what is a local problem.
(FWIW I can install package Cairo on Solaris if I use GNU make, an
undeclared dependence. But I wonder why you would want to do this
when R's own graphics devices do almost everything Cairo does, often
better since we use pango for font selection.)

Hi,
I have installed the latest version of libglib-2.0 (2.28.0) and cairo
1.10.2
Then I have compiled R 2.12.1
But when i I try to install Cairo (1.4-6) I get the following
unreferenced Symbol error:
*** installing help indices
** building package indices ...
** testing if installed package can be loaded
Error : .onLoad failed in loadNamespace() for 'Cairo', details:
call: dyn.load(file, DLLpath = DLLpath, ...)

FT_Library_SetLcdFilter: referenced symbol not found
ERROR: loading failed
* removing '/opt/gnu/R-2.12.1/lib/R/library/Cairo'
This all I have done on Solaris with the Sun Studio 11 Compiler
When I configure cairo-1.10.2 I got:
checking for FT_Library_SetLCDFilter.... yes
Looks like it is anywhere on my system.
But why R does not find it - Need I a special Environment variable to
define the location of the library that contains the object ? But from
which library this object is comming ?
Thank for any hint
Reinhard
