Error with C compiler

Below is the output from the x64 Native Tools Command Prompt:

@mspring6 Did you solve the problem ? I have the same problem.

[mspring6]

@ronyshaji I did not solve the problem, I just found a work around. I was able to build the carla solution for unreal engine by doing the "make launch" command and that successfully launches unreal engine with carla running. I then just downloaded a pre compiled binary version carla just to get the PythonAPI. Then with the from source version of Unreal Engine server running you should be able to run the PythonAPI client and connect to the server.

[ronyshaji]

@mspring6 Where did you find the pre compiled version of carla. Any tutorials avalable ?

[mspring6]

@ronyshaji just go to their website and click on get carla

[ronyshaji]

@mspring6 How did the make launch work for you ? I mean did you done anything special, when I use the Make Launch, it starts just like MAKE PythonAPI and fails with the same error as above.

[mspring6]

No I did nothing specific, it just worked for me. Make sure to follow the instructions in the build guide and have only one version of visual studio installed.

@mspring6 Thanks for your help. Finally I found a solution to the error and able to launch the UE4 editor.

BEWARE InstallCleanup.exe now is in here "C:\Program Files (x86)\Microsoft Visual Studio\Installer" instead of "To completely clean Visual Studio from the computer, go to Program Files (x86)\Microsoft Visual Studio\Installer\resources\app\layout and run .\InstallCleanup.exe -full"

@mspring6 Hallo I was able to solve the error. In my case the installation directory of gnuwin make had spaces (C:\Program Files\GnuWin32\bin) and i uninstalled from that folder and installed directly to the c drive(C:\GnuWin32\bin) and added the path to the PATH variable. Reboot the pc and run MakePythonAPI...it works (remember to delete the build folder from the carla root as it was created when you run the makepythonAPI first). May be helpful for some
