[gst-devel] Re: libgst.so needs -lm in head

[Steve Baker]

My current temporary fix is:
diff -u -r1.84 configure.base
--- configure.base	2001/09/17 06:52:09	1.84

since -lm only seems to be needed when using glib2

gstdparammanager has to be in core as it is coupled with gstelement and
it has macros that any plugin might use.

I think there will eventually be a --disable-dparams option in configure
which can remove all evidence of dparams from a compile (except maybe a
couple of macro stubs).

As for use of log() and exp(), I arbitrarily decided that core would
contain dparam support for real-time linear and logarithm values.

If requested I could move real-time logarithm into libgstcontrol so we
no longer have the -lm dependency. 

Either that or I could add log(gfloat x) and exp(gfloat x)
implementations (which I should do whether it stays in core or not).

cheers
