Re: grapher.cgi

In a UNIX environment the variable LD_LIBRARY_PATH is used to determine 
the path to shared libraries (similar to PATH for executables). If 
LD_LIBRARY_PATH is not set for a user, a number of default locations are 
used (e.g. /usr/lib/ ). Guessing that the path to libdb 
(/usr/local/BerkeleyDB.4.4/lib) is already added to root and cricket's 
LD_LIBRARY_PATH.

However to add the path for Apache you can add to httpd.conf with a line 
similar to:

SetEnv LD_LIBRARY_PATH /usr/local/BerkeleyDB.4.4/lib

(if directive already exists, simply append the path to the existing 
value delimited with a ":")

I recommend adding in httpd.conf but Solaris 8 and above also has the 
ability to add a library path for all users using a tool called crle. 
You should read the man page for crle, as you could break things if you 
accidently remove /usr/lib from everyone's lib path. Without any 
arguments, it displays the current config file contents. You can add a 
directory by using the -l switch to crle. For example, if you run crle 
on a system that has only the defaults, you’ll see:

Default configuration file (/var/ld/ld.config) not found
Default Library Path (ELF): /usr/lib (system default)
Trusted Directories (ELF): /usr/lib/secure (system default)

If you want to add /usr/local/BerkeleyDB/lib, for example, you would run:

crle -l /usr/lib:/usr/local/BerkeleyDB/lib

This creates the default config file, /var/ld/ld.config, and explicitly 
states which libraries should be in the default search path. Be sure to 
always include /usr/lib, or you’ll definitely have issues. If you now 
run just crle again, you’ll see the output:

Configuration file [3]: /var/ld/ld.config
Default Library Path (ELF): /usr/lib:/usr/local/BerkeleyDB/lib
Trusted Directories (ELF): /usr/lib/secure (system default)
