我正在尝试为名为 libnifalcon 的 NOVINT Falcon 安装驱动程序。我使用 cmake 创建了一个 make 文件,但是当我运行 make 时出现错误:
Linking CXX shared library ../../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): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libboost_program_options-mt.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[2]: ** [lib/libnifalcon_cli_base.so.1.0.1] Error 1
make[1]: ** [src/util/CMakeFiles/nifalcon_cli_base_SHARED.dir/all] Error 2
make: *** [all] Error 2
我尝试了许多编译 usinf -fPIC 的技术,但都没有奏效。谁能告诉我makefile在哪里,以及为了使用-fPIC编译要写什么?
