linux上Ocaml-makefile的一个报错

问题遇到的现象和发生背景

想要用别人编写好的程序，使用make，报了一下错误。尝试用了-fPIC 和-no-pie 都没有用，我猜测可能用的是Ocaml-makefile所以不管用，没有没兄弟精通这一块的，帮忙看看吖。下面是makefile文件

用代码块功能插入代码，请勿粘贴截图

#                   Generic Makefile for Objective Caml Programs

# $Id: Exp $

############################ Documentation ######################
#
# To use this Makefile:
# -- You must fix the value of the variable SOURCES below.
# (The variable SOURCES is the list of your Caml source files.)
# -- You must create a file .depend, using
# $touch .depend
# (This file will contain the dependancies between your Caml modules,
#  automatically computed by this Makefile.)

# Usage of this Makefile:
# To incrementally recompile the system, type
#     make
# To recompute dependancies between modules, type
#     make depend
# To remove the executable and all the compiled files, type
#     make clean
# To compile using the native code compiler
#     make opt
#
##################################################################


##################################################################
#
# Advanced usage:
# ---------------

# If you want to fix the name of the executable, set the variable
# EXEC, for instance, if you want to obtain a program named my_prog:
EXEC = ukano

# If you need special libraries provided with the Caml system,
# (graphics, arbitrary precision numbers, regular expression on strings, ...),
# you must set the variable LIBS to the proper set of libraries. For
# instance, to use the graphics library set LIBS to $(WITHGRAPHICS):
# LIBS = $(WITHGRAPHICS)

# You may use any of the following predefined variable
# WITHGRAPHICS : provides the graphics library
# WITHUNIX : provides the Unix interface library
# WITHSTR : provides the regular expression string manipulation library
# WITHNUMS : provides the arbitrary precision arithmetic package
# WITHTHREADS : provides the byte-code threads library
# WITHDBM : provides the Data Base Manager library
#

运行结果及报错内容

relocation R_X86_64_32 against "rodata.str1.1" can not be used when making a PIE object
制作PIE对象时，不能使用针对“rodata.str1.1”的重定位R_X86_64_32
分析：
在生成共享库的工程调用中会报错该库编译时没有使用–fPIC编译
fPIC 作用于编译阶段，告诉编译器产生与位置无关代码(Position-Independent Code)，则产生的代码中，没有绝对地址，全部使用相对地址，故而代码可以被加载器加载到内存的任意位置，都可以正确的执行。这正是共享库所要求的，共享库被加载时，在内存的位置不是固定的
解决思路：
出现这个问题检查整个编译过程是否都采用–fPIC的方式编译的应该就可以了
另外提供一个同样报错的实例笔记，供你参考，实例出现该问题是库版本问题：https://www.freesion.com/article/5229856714/
【所以，细心检查下环境匹配也很重要】
