Topic: gd

[Sean Reynaud]

I am trying to install mgstats (http://wizard.ae.krakow.pl/~mike/mgstat/) to analyze the mod_gzip log files.
I downloaded the source and tried to install it.  When running configure, it complains that the GD library is not installed.  However, I have installed gd 1.8.4-4.
Am I missing part of the GD library or how can I get the mgstats configure to recognize GD.

GD library not found. Mgstat will run but won't produce graphics.
Please get GD library from http://www.boutell.com/gd
Now, you can type 'make' and 'make install'

Just as a guess, you probably need to install the gd-devel package.

I don't know how sophisticated you want your stats to be, but you can get a decent idea about mod_gzip performance from the server-manager using View log file>httpd/mod_gzip.log.  I simply compare the number of lines containing "OK" to the total number of lines for a rough estimate of gzip usage.  Depending on what exactly you are trying to find out, a pretty quick Perl script might do what you need, as well.

I had thought about that and have the gd-devel and gd-progs rpm installed just in case. (v 1.8.4-4)

I think this may be causing some of the issues I have with YAPPA as well.  I can only view images at the original size.

Thanks for the suggestion though...
