无法编译：部分文本中无法识别的重定位 0x2a

Question

我在编译时收到错误信息"make"

$ make
g++ -fopenmp  -o lang.test main.o -I../../../include/Lheader -I../../../include -L../../../lib/ -llmi -lblas -lboost_regex -lpthread -lleveldb
/usr/bin/ld: ../../../lib//liblmi.a(LMInterface.o): unrecognized relocation (0x2a) in section `.text'
/usr/bin/ld: final link failed: Bad value
collect2: error: ld returned 1 exit status

我找不到上述问题的任何解决方案。

GCC版本和ld版本是这样的：

$ gcc --version
gcc (Ubuntu 5.4.1-2ubuntu1~14.04) 5.4.1 20160904

如何解决这个编译问题？

Answer 1

x86-64 上的重定位 42 是 R_X86_64_REX_GOTPCRELX。这些重定位被使用 for optimizations implemented in binutils 2.26 and later.

您需要升级您的 binutils 版本，或者重新编译您要使用当前工具链版本的库。

Answer 2

您需要升级 GCC 版本。您可以通过运行这些命令执行此操作：

yum install centos-release-scl -y
yum install devtoolset-7 -y
scl enable devtoolset-7 bash
