compilation error related to itpp

[gariac]

I'm not a programmer but this error reads like a type definition error.

make

This was solved in issue #19. Go to
https://ubuntuforums.org/showthread.php?t=2349493

I edited the CMakeLists.txt in the src directory. However later I noticed the same file name exists in the top level directory so perhaps that is the file that should be edited but I am not going to break what I already fixed. Thus
Edit CMakeLists.txt

I added these lines:

#added line per https://ubuntuforums.org/showthread.php?t=2349493
SET (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++03")

Since only the owner can change the code I suppose this will be a bug forever. I am at least going to notify the website that suggested using this program. If you were referred to this git by another page you might want to reference this minor patch.

As an aside I have used this program in the past and the cell search sometimes crashed. If you are just here to get a frequency offset measurement, you can find the LTE frequency used by your phone with a number of apps. Just use that frequency rather than search.
