disable all plugins whose requirements cannot be fulfilled (any other plugin
will be enabled). To enable a plugin, install missing dependencies (see
section `Prerequisites' above) and rerun `configure'. If you specify the
- `--enable-<plugin>' configure option, you can force the plugin to be built.

+ dencies for the specified plugin are not met. In that case you can force the
+ plugin to be built using the `--enable-<plugin>=force' configure option.
This will most likely fail though unless you're working in a very unusual

+ specify the `--enable-all-plugins' or `--disable-all-plugins' configure

By default, collectd will be installed into `/opt/collectd'. You can adjust
this setting by specifying the `--prefix' configure option - see INSTALL for
prefixed to all installation directories. This might be useful when creating
packages for collectd.
+Configuring with libjvm
+-----------------------
+
+ To determine the location of the required files of a Java installation is not
+ an easy task, because the locations vary with your kernel (Linux, SunOS, …)
+ and with your architecture (x86, SPARC, …) and there is no ‘java-config’
+ script we could use. Configuration of the JVM library is therefore a bit
+ tricky.
+
+ The easiest way to use the `--with-java=$JAVA_HOME' option, where
+ `$JAVA_HOME' is usually something like:
+ /usr/lib/jvm/java-1.5.0-sun-1.5.0.14
+
+ The configure script will then use find(1) to look for the following files:
+
+ - jni.h
+ - jni_md.h
+ - libjvm.so
+
+ If found, appropriate CPP-flags and LD-flags are set and the following
+ library checks succeed.
+
+ If this doesn't work for you, you have the possibility to specify CPP-flags,
+ C-flags and LD-flags for the ‘Java’ plugin by hand, using the following three
+ (environment) variables:
+
+ - JAVA_CPPFLAGS
+ - JAVA_CFLAGS
+ - JAVA_LDFLAGS
+
+ For example (shortened for demonstration purposes):
+
+ ./configure JAVA_CPPFLAGS="-I$JAVA_HOME/include -I$JAVA_HOME/include/linux"
+
+ Adding "-ljvm" to the JAVA_LDFLAGS is done automatically, you don't have to
+ do that.
Crosscompiling
--------------
that the compiled binary actually behaves as it should, but since NANs
are likely never passed to the libm you have a good chance to be lucky.
+ Likewise, collectd needs to know the layout of doubles in memory, in order
+ to craft uniform network packets over different architectures. For this, it
+ needs to know how to convert doubles into the memory layout used by x86. The
+ configure script tries to figure this out by compiling and running a few
+ small test programs. This is of course not possible when cross-compiling.
+ You can use the `--with-fp-layout' option to tell the configure script which
+ conversion method to assume. Valid arguments are:
+
+ * `nothing' (12345678 -> 12345678)
+ * `endianflip' (12345678 -> 87654321)
+ * `intswap' (12345678 -> 56781234)
+
