fedora中C代码编译问题

Question

大家好，我正在尝试构建一个 jni 库。构建在 Windows 中正常工作，但在 Linux fedora 中我遇到了一个问题，它抛出这样的错误

/usr/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/4.1.2/crtbeginT.o: relocation R_X86_64_32 against `__DTOR_END__' can not be used when making a shared object; recompile with -fPIC

我是这样编译代码的

gcc -o libTest.so -shared -I/usr/java/jdk1.6.0_18/include -I/usr/java/jdk1.6.0_18/include/linux arrayUtil.c -static -lc

谁能告诉我哪里出错了？

这是我从 JNI 调用时的错误:

从编译命令中删除-static。 -static 不应该用于构建共享对象，它用于构建静态链接的可执行文件。

检查here有关 -static 和链接器的更多信息。
