意外的重定位类型 0x03

unexpected reloc type 0x03(意外的重定位类型 0x03)

问题描述

我正在尝试执行用我自己的库编译的程序，但是当我执行该程序时出现以下错误:

I'm trying to execute a program compiled with my own library, but when i execute the program I get the following error:

./a.out 
./a.out: error while loading shared libraries: ../../lib-arm/libCustomLibrary.so: unexpected reloc type 0x03

这只是在 Release 执行中发生，在 Debug 执行中一切正常.

That just happens with the Release execution, with the Debug execution all works fine.

您认为这可能是哪里的问题?

Where do you think that may be the problem?

CustomLibrary 库与以下参数链接:

The CustomLibrary Library is linked with the following arguments:

-lSubLibrary -fPIC -Wl,-Bstatic -lboost_system -lboost_filesystem -lboost_thread -lpthread -Wl,-Bdynamic -lrt

我附上了我的库的 lld unix 库命令输出.

I attatch the lld unix library command output for my library.

ldd ../../lib-arm/libCustomLibrary.so 
/usr/lib/arm-linux-gnueabihf/libcofi_rpi.so (0x76e5d000)
libSubLibrary.so => ../../lib-arm/libSubLibrary.so (0x76e2d000)
librt.so.1 => /lib/arm-linux-gnueabihf/librt.so.1 (0x76e10000)
libstdc++.so.6 => /usr/lib/arm-linux-gnueabihf/libstdc++.so.6 (0x76d3e000)
libm.so.6 => /lib/arm-linux-gnueabihf/libm.so.6 (0x76ccd000)
libgcc_s.so.1 => /lib/arm-linux-gnueabihf/libgcc_s.so.1 (0x76ca5000)
libc.so.6 => /lib/arm-linux-gnueabihf/libc.so.6 (0x76b75000)
libdl.so.2 => /lib/arm-linux-gnueabihf/libdl.so.2 (0x76b6a000)
libpthread.so.0 => /lib/arm-linux-gnueabihf/libpthread.so.0 (0x76b4b000)
/lib/ld-linux-armhf.so.3 (0x76f05000)

推荐答案

来自 https://lists.linaro.org/pipermail/linaro-toolchain/2012-November/002939.html :

重定位类型 3 是 R_ARM_REL32，它是静态重定位而不是允许在共享对象中.你是如何创建共享库的?制作确保使用 -fPIC 编译所有进入其中的代码.

Relocation type 3 is R_ARM_REL32 which is a static relocation not allowed in shared objects. How did you create the shared lib? Make sure you compile all the code going into it with -fPIC.

换句话说，您在链接程序时使用了 -fPIC，但在构建共享库时可能没有使用.

In other words, you are using -fPIC when linking your program, but perhaps not when building your shared library.
