seetalib问题记录

在arch上完全没有问题的faceTest.cpp，到了centos7上报错

seetalib/lib/libviplnet.so: undefined reference to `std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >::_M_assign(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)@GLIBCXX_3.4.21'

seetalib/lib/libviplnet.so: undefined reference to `vtable for std::__cxx11::basic_stringbuf<char, std::char_traits<char>, std::allocator<char> >@GLIBCXX_3.4.21'

其中，make.sh如下，相比arch上删除了libopencv_？（包含imread等函数），这里是opencv版本差异造成的

另外在centos7上，lib的路径为 /usr/lib64/

#!/bin/bash
 g++ faceTest.cpp -o face -Lseetalib/lib -lseeta_fa_lib -lseeta_facedet_lib -lviplnet -L/usr/lib64/ -lopencv_core -lopencv_highgui -lopencv_imgproc  -std=c++11

错误原因应为centos7上gcc和变异seetalib库文件的gcc版本不一致，c++11和老版本的命名多了__cxx11，在centos7上不能识别。但是yum更新不了gcc。按stackoverflow上的方法添加宏定义也并没有起作用。另外想起当时在centos上编译识别模块好像是出了问题没有编译成功，这个库应该是不能用的，可能和这个有关系。

待解决。
