freetype/fontconfig/cairo/pango version problem? / fontconfig compilation problem?

[oetiker]

doc/rrdbuild.pod is not very clear about these versions:

{{{ grep cairo doc/rrdbuild.pod There is a problem with F on opensolaris. It suggests that xrender is required for compilation with cairo. This is not true and also perl -i~ -p -e 's/(Requires._?)\s_xrender.*/$1/' /usr/lib/pkgconfig/cairo.pc wget http://oss.oetiker.ch/rrdtool/pub/libs/cairo-1.6.4.tar.gz gunzip -c cairo-1.4.10.tar.gz | tar xf - cd cairo-1.4.10

configure: WARNING:

• I could not find a working copy of pangocairo. Check config.log for hints on why this is the case. Maybe you need to set LDFLAGS and CPPFLAGS appropriately so that compiler and the linker can find libpango-1.0 and its header files. If you have not installed pangocairo, you can get it either from its original home on

  http://ftp.gnome.org/pub/GNOME/sources/pango/1.17

  You can find also find an archive copy on

But as FcFini is documented in fontconfig, this could also be a fontconfig configuration/compilation/installation problem, and only rrdbuild.pod should be corrected regards

[human] == order of directories in PKG_CONFIG_PATH is important == as not being able to get rid of old freetype: {{{ rpm -q freetype freetype-2.1.4-7.el3 }}} I use {{{ export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig }}} which lets cairo 1.6.4 recognize freetype another {{{ export LD_LIBRARY_PATH=/usr/local/lib }}} configure and make works!

... perhaps helpful for users with old systems ;-))
