将静态(.a)库与共享(.so)库链接,获取错误“针对本地符号重定位R_X86_64_32S;使用-fPIC重新编译”

时间:2013-05-15 22:13:21

标签: c++ eclipse 64-bit fpic

使用eclipse在redhat中使用g ++ 64位进行编译。

编译错误: ../lib-EL5-64bit/libskd3_clnt_30134500.a(skd_clnt.o):在创建共享对象时,不能使用针对“本地符号”的重定位R_X86_64_32S;用-fPIC重新编译

我尝试过的事情 我将-fPIC添加到c ++编译器标志以及链接器标志中。它已存在于编译器标志中,我只是在g ++之后直接将其移动到列表的末尾。

我已经要求.a库的创建者使用-fPIC重新编译它仍然会出现同样的错误

有没有办法确保他们的库是用-fPIC编译的? 错误消息是否说我需要使用-fPIC编译我的.so,或者.a文件需要使用-fPIC编译? 我还能检查什么?

这是make文件(由eclipse自动生成)

当您静态编译时,汇编程序指令将假定有关代码局部性的某些内容,例如:任何跳跃都在跳跃/调用指令的4GB范围内。 (假设64b x86)。共享库的加载距离可能远远超过4GB,因此跳转/调用不适合。

当使用-fPIC(位置无关代码)进行编译时 - 编译器将确保代码和本地数据引用是位置独立的,并且在最坏情况/最大寻址模式下安排调用/跳转到外部(例如满64b)。

当您收到此错误时,静态库无法跳转到共享库 - 上面的快捷方式已被删除。唯一的解决方案是使用-fPIC重新编译。 (从技术上讲,32位跳转可能只有5个字节但你需要9个字节[1个操作码+ 8个用于addr];所以没有多少汇编器聪明能解决这个问题 - 不是没有其他一些卑鄙的操作,比如使用INT指令提供短手跳。)

现在大多数都可以/应该用-fPIC编译而不管是否共享 - 除非性能很重要。
