Compilation fails with error: 'constexpr' needed for in-class initialization of static data member #25

When compiling via "make" the following error message appears:

../UMTS/UMTSRadioModem.h:181:16: error: ‘constexpr’ does not name a type i got same error. does anyone fix that?

Same here. Researching possible solutions

alejandro-amo commented 5 years ago

found it. #25 and #26 are caused for more or less the same thing. see https://github.com/RangeNetworks/OpenBTS-UMTS/issues/26#issuecomment-461852514

If not working just with gcc-5 g++-5 try to add make CXXFLAGS=-std=c++11
