unable to compile: unrecognized relocation 0x2a in section text

Question

I have received an error message when compiled "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

I cannot find any solution for above problem.

GCC version and ld version are like these:

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

How to fix this compile problem?

Answer 1

Relocation 42 on x86-64 is R_X86_64_REX_GOTPCRELX. These relocations are used for optimizations implemented in binutils 2.26 and later.

You will either need to upgrade your binutils version, or re-compile the library you want to use with your current toolchain version.

Answer 2

You need upgrade your GCC version. You can do so by running these commands:

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