Hi Andras,

i wish to test it, but it fails to compile with

gcc duster.c sanei_irclean.c -o duster

with the message:
/tmp/ccerPEcp.o: In function `sanei_irclean':
/tmp/ccerPEcp.o(.text+0x450): undefined reference to `cos'
/tmp/ccerPEcp.o(.text+0x492): undefined reference to `sin'
/tmp/ccerPEcp.o(.text+0x54b): undefined reference to `exp'
collect2: ld returned 1 exit status

my math.h ist from the package :


Any hint how to resolve this problem?
