R devel - May 2011 - Error in svg() : cairo-based devices are not supported on this build

Hello,

Sorry if it is not the right place..


I installed R-2.13.0 on a x86_64 linux server.
All went fine, but the svg()  function yells:
> svg()
Error in svg() : cairo-based devices are not supported on this build

I have the Cairo, cairoDevice, RSvgDevice packages installed, and running.
> Cairo.capabilities()
  png  jpeg  tiff   pdf   svg    ps   x11   win
 TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE FALSE

I tried to google around unsuccessfully. The only thing I noticed in
config.log is:
r_cv_has_pangocairo=no
r_cv_cairo_works=yes
r_cv_has_cairo=yes
#define HAVE_WORKING_CAIRO 1
#define HAVE_CAIRO_PDF 1
#define HAVE_CAIRO_PS 1
#define HAVE_CAIRO_SVG 1


So what can be wrong ??

Thank you

Karl

Those are irrelevant for svg() which is provided by built-in cairo support in R,
not the packages, so you want to check capabilities():

cairo 
 TRUE 

But if you have working Cairo package can simply use CairoSVG() instead of
svg().

Check what configure is saying when you build R and config.log. You may

I managed to compile it successfully with pango-cairo support by editing the
configure script and adding the pangoxft module to the pkg-config list:
%diff -c configure.bak  configure
*** configure.bak       2011-05-31 16:16:55.000000000 +0200
--- configure   2011-05-31 16:17:21.000000000 +0200
***************
*** 31313,31319 ****
  $as_echo "$r_cv_has_pangocairo" >&6; }
    if test "x${r_cv_has_pangocairo}" = "xyes"; then
      modlist="pangocairo"
!     for module in cairo-xlib cairo-png; do
        if "${PKGCONF}" --exists ${module}; then
        modlist="${modlist} ${module}"
        fi
--- 31313,31319 ----
  $as_echo "$r_cv_has_pangocairo" >&6; }
    if test "x${r_cv_has_pangocairo}" = "xyes"; then
      modlist="pangocairo"
!     for module in cairo-xlib cairo-png pangoxft; do
        if "${PKGCONF}" --exists ${module}; then
        modlist="${modlist} ${module}"
        fi


I do not know if it is an error in the configure script or just a
peculiarity of my installation. All these libs (pango, cairo, gtk, glib)
have been installed manually from tarballs.

Best,

Karl
