configure: WARNING:

* I could not find a working copy of freetype2. 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 libfreetype and its header files. If
  you have not installed freetype2, you can get it either from its original home on

     http://prdownloads.sourceforge.net/freetype/

  You can find also find an archive copy on

     http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/pub/libs

  The last tested version of freetype2 is 2.1.9.

Freetype2 jsem úspěšně zkompiloval
Nevím co znamená a co udělat s LDFLAGS CPPFLAGS.
Prosím poradí někdo.

Nerozumim tomu ale poradil jsem si následovně:
.../rrdtool/# env CPPFLAGS="-I/usr/local/src/cgilib-0.5/ -I/usr/local/include/freetype2 -I/usr/local/include/libart-2.0" LDFLAGS="-L/usr/local/src/cgilib-0.5/" ./configure

LDFLAGS jsou parametry linkeru a CPPFLAGS parametry preprocesoru c. jinak, pkgconfig nemohl najit knihovnu freetype2 (asi proto ze sis ji zrejme nainstaloval do /usr/local)

[Gryffus]

A jak si zvolim kam chci freetype2 nainstalovat?
