[rrd-users] Re: Announce RRDtool 1.2.0

[Christopher Bergeron]

Tobias, I'm trying to compile 1.2.x on Fedora Core 3, and the only 
library that seems to be missing is cgilib.

I downloaded it from your site, compiled it, and tried to install it 
using "make install" but that failed (which doesn't seem unreasonable). 
I copied the libcgi.a file to /usr/lib and ran 'ldconfig'.  I re-tried 
configure for 1.2 and it bailed with this result:

checking for pkg-config... pkg-config
configure: WARNING:
----------------------------------------------------------------------------
* I found a copy of pkgconfig, but there is no cgilib.pc file around.
  You may want to set the PKG_CONFIG_PATH variable to point to its
  location.
----------------------------------------------------------------------------

configure: WARNING:
----------------------------------------------------------------------------
* I could not find a working copy of cgilib. 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 libcgi and its header files. If
  you have not installed cgilib, you can get it either from its original 
home on

     http://www.infodrom.org/projects/cgilib

  You can find also find an archive copy on

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

  The last tested version of cgilib is 0.5.

       LIBS=-lm
   LDFLAGS=
  CPPFLAGS=

*****************************************



Where should I install the cgilib.pc file?  It doesn't appear that 
Fedora Core 3 has pkgconfig installed.  I'm looking at a different box 
(Slack 9), and it has $PKG set at: /usr/local/lib/pkgconfig.

You may want to mention this to your FC/Rhat users because this (Fedora) 
distro doesn't appear to have pkgtool installed by default.

I'll install pkgtool on this FC3 box and let you know what my results are.

Anyway, I just wanted it to ya...

Kind regards,
Chris Bergeron
