链接Boost静态库

Question

我正在尝试使用Boost和OpenCV中的静态库来编译共享库。下面是我用来编译库的命令。

g++ -fPIC libsaliency.cpp -shared -o libsaliency.so 
                -I/home/poiesi/data/libraries/boost_1_66_0/installed_w_contrib_static/include -I/home/poiesi/data/libraries/opencv-3.4.0/installed_w_contrib_static/include 
                -Wl,--whole-archive 
                    /home/poiesi/data/libraries/boost_1_66_0/installed/lib/libboost_graph.a 
                    /home/poiesi/data/libraries/boost_1_66_0/installed/lib/libboost_filesystem.a 
                    /home/poiesi/data/libraries/boost_1_66_0/installed/lib/libboost_system.a 
                    /home/poiesi/data/libraries/opencv-3.4.0/installed_w_contrib_static/lib/libopencv_core.a 
                    /home/poiesi/data/libraries/opencv-3.4.0/installed_w_contrib_static/lib/libopencv_highgui.a 
                    /home/poiesi/data/libraries/opencv-3.4.0/installed_w_contrib_static/lib/libopencv_imgproc.a 
                    /home/poiesi/data/libraries/opencv-3.4.0/installed_w_contrib_static/lib/libopencv_imgcodecs.a 
                    /home/poiesi/data/libraries/opencv-3.4.0/installed_w_contrib_static/lib/libopencv_features2d.a 
                    /home/poiesi/data/libraries/opencv-3.4.0/installed_w_contrib_static/lib/libopencv_video.a 
                -Wl,--no-whole-archive

但是，我有这个错误：

usr/bin/ld: /home/poiesi/data/libraries/boost_1_66_0/installed/lib/libboost_graph.a(read_graphviz_new.o): relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a shared object; recompile with -fPIC
        /home/poiesi/data/libraries/boost_1_66_0/installed/lib/libboost_graph.a(read_graphviz_new.o): error adding symbols: Bad value
        collect2: error: ld returned 1 exit status
        Makefile:7: recipe for target 'saliency' failed
        make: *** [saliency] Error 1

这是否意味着我必须使用-fPIC命令重新编译Boost？我在网上查了一下但是我没有找到很多关于它的信息。这让我想知道我是否正在寻找合适的东西。你有什么建议吗？

编辑：正如迈克下面的建议，我重新编译了Boost，如下所示：

./b2 cxxflags="-fPIC" link=static install

我现在可以编译我的.so库了。
