Answer 1

I try to google http://www.cplusplus.com/forum/unices/61996/.
I guess the problem may caused by I add a '-shared' option to linker.
But, if I don't add such option, the linker will show another strange message. (I'm using STLinux's gcc instead of Arch Linux's gcc as basement).
Building program /home/dlin/abs/local/apt/src/apt-0.9.7.7/bin/methods/file
/usr/bin/ld: /home/dlin/abs/local/apt/src/apt-0.9.7.7/bin/methods/file: hidden symbol `__movmem_i4_odd' in /usr/lib/gcc/sh4-linux/4.2.4/libgcc.a(_movmem_i4.o) is referenced by DSO

collect2: ld returned 1 exit status
make[2]: *** [/home/dlin/abs/local/apt/src/apt-0.9.7.7/bin/methods/file] Error 1
if I change the '-shared' to '-nostdlib'. the linker shows
