我试图在Ubuntu Linux上使用CMake编译软件，但出现以下错误：
[ 71%] Linking CXX executable convert_imageset

我的理解是，链接器失败，因为/usr/local/lib/libboost_python.so lib不包含提到的符号。但是我可以看到提到的符号在库中显示：
wakatana@machine:~$ nm -D /usr/local/lib/libboost_python.so | egrep 'PyString_Size|PyString_FromStringAndSize|PyString_FromString|PyInt_Type|PyInt_FromLong|PyFile_FromString'
U PyFile_FromString
U PyInt_FromLong
U PyInt_Type
U PyString_FromString
U PyString_FromStringAndSize
U PyString_Size
我在这里想念的东西。如何调试这些类型的错误？
