Hi sir:
I think i need your help now . I downloaded the or1k/mp3 to my pc
and uncompressed it. Then I entered the the subdir:mp3/sw/mad-xess
and did as the file "readme" told me.
The commands are as follows :
The first steps are done successfully. The flash.c are generated ,the source files in libmad are compiled and linked to libmad.a successully and the files in the mad-xess are all compiled to *.o. But to my disappointment ,errors occur in the following linking process . The errors are : or32-rtems-gcc -T xess.ld -o minimad reset.o minimad.o fsyst.o audio_oss.o audio.o memcpy.o memmove.o flash.o libmad/libmad.amemcpy.o: In function `_memcpy': memcpy.o(.text+0x0): multiple definition of `_memcpy' /opt/or32-rtems/lib/gcc-lib/or32-rtems/3.2.3/../../../../or32- rtems/lib/crt0.o:/tar/or1k/b-gcc/or32- rtems/newlib/libc/sys/rtems/../../../../../../gcc- 3.2.3/newlib/libc/sys/rtems/crt0.c:31: first defined here /opt/or32-rtems/lib/gcc-lib/or32-rtems/3.2.3/../../../../or32- rtems/bin/ld: warning: no memory region specified for section `.rodata' /opt/or32-rtems/lib/gcc-lib/or32-rtems/3.2.3/../../../../or32- rtems/bin/ld: section .rodata [0001756c -> 0001b147] overlaps section .data [000098a8 -> 0006b3bb] collect2: ld returned 1 exit status make[1]: *** [minimad] Error 1 make[1]: Leaving directory `/tar/or1k/mp3/sw/mad-xess' make: *** [all] Error 1 I don't know what kind of codes should be put in the "rodata" section and why it overlaps the section of data. Also why there is a multiple definitions of "memcpy" ? By the way, my linux version on pc is 9.1,and i wish i won't put any effect. Thanks for your help!!!
