gcc - 无法编译: unrecognized relocation 0x2a in section text

Question

编译“make”时我收到一条错误消息

$ 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

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。这些重定位用于for optimizations implemented in binutils 2.26 and later .

您需要升级 binutils 版本，或者重新编译要与当前工具链版本一起使用的库。
