hello everyone,

I have a question about the makefile of this OSGPS program. In the makefile=
, there are some contents as follows:

PROJ=3Dgpsrcvr
SRC=3D  gpsfuncs.c gpsrcvr.c nav_fix.c linuxusr.c nmea.c FwInter.c rinex.c
GUSRC=3Dgpsfuncs.c gpsrcvr.c nav_fix.c interfac.c
SOFTSRC=3DSoftOSGPS.c gpsfuncs.c nav_fix.c rinex.c gpsisr.c gp2021.c interf=
ac.c

what are the differences between the SRC =A1=A2GUSRC and the  SOFTSRC? And =
why there are two "main" functions in this program, respectively in the fil=
e gpsrcvr.c and SoftOSGPS.c=A3=BF

thank you very much!    =20
