编辑CMakeLists.txt以使用-fPIC编译 [英] Edit CMakeLists.txt to compile with -fPIC
本文介绍了编辑CMakeLists.txt以使用-fPIC编译的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在为一个名为libnifalcon的NOVINT Falcon安装驱动程序。我使用cmake创建一个make文件，但是当我运行make我得到的错误：
链接CXX共享库../ ../lib/libnifalcon_cli_base.so
/ usr / bin / ld：/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libboost_program_options- mt.a（cmdline.o）：在创建共享对象时，不能使用针对`.rodata.str1.1'的重定位R_X86_64_32;使用-fPIC重新编译
/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libboost_program_options-mt.a：无法读取符号：错误值
collect2：ld返回1退出状态
make [2]：** [lib / libnifalcon_cli_base.so.1.0.1]错误1
make [1]：** [src / util /CMakeFiles/nifalcon_cli_base_SHARED.dir/all]错误2
make：*** [all]错误2
$ b b
我已经尝试了许多技术来编译usinf -fPIC，但没有一个工作。任何人都可以告诉我在makefile中的什么地方，以及为了使用-fPIC编译而编写什么？

解决方案可以在Makefile中添加以下内容。
CFLAGS + = -fPIC
CPPFLAGS + = -fPIC
但是，真的，你应该修改cmake的代码，然后重新生成Makefile。应该有一个方法添加到cmake中的CFLAGS。
编辑：看起来你可以在cmake输入文件中设置cmake变量CMAKE_C_FLAGS和CMAKE_CXX_FLAGS。
I'm trying to install drivers for a NOVINT Falcon called libnifalcon. I used cmake to create a make file, but when I run make I get the error:

I've tried many of the techniques to compile usinf -fPIC but none have worked. Can anyone tell me where in the makefile, and what to write in order to compile using -fPIC?

解决方案
You can add the following to the Makefile.
CFLAGS += -fPIC
CPPFLAGS += -fPIC
But, really, you should be modifying the code for cmake, and then regenerate the Makefile. There should be a way to add to CFLAGS in cmake.
EDIT: Seems like you can set the cmake variables CMAKE_C_FLAGS and CMAKE_CXX_FLAGS in the cmake input file.
这篇关于编辑CMakeLists.txt以使用-fPIC编译的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
