cmake Error: could not load cache

[Luge1995]

I have fully build the system by the Installation document, but when I run the following command: _cmake --build build --target runsimulte-cars I got a problem, the command line terminal output this: could not load cache I tried to solve this but failed，is there anyone meeting the same problem? Thanks for your help

Hi Luge,

Are you sure that you ran cmake --build . before running cmake --build build --target run_simulte-cars ?

Unfortunately, I don't have enough information to go on with what you have explained. Maybe if this doesn't help tell me some more about your system i.e. what OS you have, OMNeT++ version and SUMO versions, they shouldn't impact on cMake but it's more to go on.

Here is my building environment list: _

• Ubuntu 18.04
• SUMO 1.3.1
• CMake 3.16.0
• GNU GCC 7.4
• OMNeT++ 5.5
• Boost 1.65.1

_ I have successfully make all the necessary submodules by command make all and run command cmake --build before running _cmake --build build --target runsimulte-cars .Then it throws the error, could not load cache, I tried to google it, but the methods did not work.... Thanks a lot for your reply.
