After using C + + to implement some algorithm functions, there is an error when calling Python:
AttributeError: /..../libHessian4Nii.so: undefined symbol: callVesselSegNiiAccording to Du Niang, it is because the function name will be renamed in the C + + compiled file (which is convenient to realize the overload function), so the function name cannot be found when calling the script.
The solution is to use extern “C” Just enclose the header file to be exposed. Examples are as follows:
extern "C"{
int callVesselSegNii(char* oriNiiFile, char* maskNiiFile, char* save_path);
}
After recompilation, call the normal!!!!
