[alsa-devel] [PATCH] Always link to libm
From: Alexander Stein alexander.stein@systec-electronic.com
Starting with commit 9b6df1cf64ea7ccb329b4922d138c1f36ace00c0 control: add ASCII parsers from amixer ctlparse.c uses ceil() and so libm is need unrelated to soft- or hardfloat.

The softfloat option is intended to avoid floating-point code.
The root cause of this problem is that ctlparse.c uses floatin-point calculations unconditionally; it should be rewritten to use integer math, or to drop the float parsing if compiled with softfloat.
