Configuring / Compiling / Installing
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.
- This will most likely fail though unless you're working in a very unusual
- setup and you really know what you're doing.
+ `--enable-<plugin>' configure option, the script will fail if the depen-
+ dencies for the specified plugin are not met. If you specify the
+ `--disable-<plugin>' configure option, the plugin will not be built. Both
+ options are meant for package maintainers and should not be used in everyday
+ situations.
By default, collectd will be installed into `/opt/collectd'. You can adjust
this setting by specifying the `--prefix' configure option - see INSTALL for
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)
+
