Mode4 error - fatal error: 'inet/transportlayer/contract/udp/UDPSocket.h' file not found

[admf1]

Hello, I'm a student and new to VANET and Omnet in general

I'm trying to implement the Mode4 simulation.
I have not been able to compile and build the project.

I changed the name of the project to CV2X, however, it was not working previously either.
I've changed the name of the packages from lte to CV2X.

Currently using:

Omnet 5.6.2
INET 4.2.2
SimuLTE 1.2.0
Veins 5.1

Error Message:

cd src && make

Not all, but some of files referenced from Inet have the small red x's next to.

And also,

Your combination of the Simulte and INET versions do not match: In newer inet-Versions, classes like UDPSocket.h were renamed to UdpSocket.h.

Therefore, the includes needed to be adapted, but that is already done in the current Simulte master, e.g. see https://github.com/inet-framework/simulte/blob/master/src/apps/alert/AlertReceiver.h in line 17

Please check out the current simulte master, clean & build and then it should work.
