再请高手赐教：wrong ELF class: ELFCLASS64，十分感谢

编译.so库时若不用-fPIC,会编不过有错误如下：

linux-z03057:~/workspace/CtoJavaTest # g++ -I/home/z03057/src/jdk1.6.0/include -I/home/z03057/src/jdk1.6.0/include/linux -o testdll.so -shared GetPid.c

/usr/lib64/gcc/x86_64-suse-linux/4.1.0/../../../../x86_64-suse-linux/bin/ld: /tmp/ccq6CLL8.o: relocation R_X86_64_32 against `__gxx_personality_v0' can not be used when making a shared object; recompile with -fPIC

/tmp/ccq6CLL8.o: could not read symbols: Bad valuecollect2: ld returned 1 exit status

linux-z03057:~/workspace/CtoJavaTest #

运行时，出现以下错误：
