[Ipopt] UNKNOWN_MATRIX_TYPE in IpTripletHelper.cpp

Hi All :

I compiled ipopt 3.4.1, ran a problem but have some error in IPOPT.OUT as below:

Exception of type: UNKNOWN_MATRIX_TYPE in file "ipopt/IpTripletHelper.cpp" at line 95


 Exception message: Unknown matrix type passed to TripletHelper::GetNumberEntries


EXIT: Some uncaught Ipopt exception encountered.

Can anyone give some suggestions to fix? I believe this is a machine related problem.
