[mpeg2-dev] Error Compiling mpeg2dec using sparc-elf-gcc

[ardimas a. <ard...@ya...>]

hi guys, let me introduce my self because I am a new member. My name is Ardimas. Electrical Engineering Undergraduate Student in ITB, Indonesia.

I have a problem when I tried to compile mpeg2dec package using sparc (cross compiler of uP leon). 

sparc-elf-gcc mpeg2dec.c gettimeofday.c video_out.c video_out_null.c video_out_pgm.c  decode.c dump_state.c alloc.c header.c cpu_state.c cpu_accel.c slice.c idct.c motion_comp.c rgb.c rgb_vis.c -o mpeg2dec.exe

and the result is :
/cygdrive/c/DOCUME~1/KP/LOCALS~1/Temp/ccbhMdJk.o: In function `sigill_handler': cpu_accel.c:(.text+0x70): undefined reference to `sigprocmask' /cygdrive/c/DOCUME~1/KP/LOCALS~1/Temp/ccbhMdJk.o: In function `arch_accel': cpu_accel.c:(.text+0xd8): undefined reference to `sigprocmask' cpu_accel.c:(.text+0x164): undefined reference to `sigprocmask' /cygdrive/c/DOCUME~1/KP/LOCALS~1/Temp/ccMgiDgd.o: In function `mpeg2_mc_init': motion_comp.c:(.text+0x24): undefined reference to `mpeg2_mc_vis' motion_comp.c:(.text+0x28): undefined reference to `mpeg2_mc_vis'

can you guys help me? I'm so freakin' crazy to find this out.
thx so much
