^{Originally posted by ThibaultFy August 13, 2021} I'm having trouble with my Windows build for 0.9.12. I'm getting the following message:

-[install_boost]: [B2 ERROR] An error ocurred while installing using "b2.exe". -[install_boost]: Exiting with error...

Thanks for your help !

My problem solved itself by removing the build folder and changing the path on my repo... I don't have more explanation than this...

Hi Could you guide me on how to do "make pythonAPI" command? I run it on X64 native tool command prompt but it crashes all the time. Thanks

Hi, I can't really help you from scratch, but you may find a lot of information on the Carla website, discord or github. If you have a recurrent issue, maybe you should open a specific one with detailed in order to ask for help to the carla community :)

Hi

I'm having same issue.... I deleted build folder and it is partially working, but want to know what you mean by "changing path on my repo"? I wanna give it a try to see if it works

I also have the same problem with @ThibaultFy for Windows Build. Carla version is 0.9.12

[khemrind-idsi]

I'm having the same issue with 0.9.12. I've followed the latest docs for building in Windows, but this error keeps occurring:

C:\UnrealProjects\CARLA\Build\boost-1.72.0-source\boost\compatibility\cpp_c_headers\cwctype

[BedirhanKeskin]

I was having the error when I run "make Launch". I downgraded the python version to 3.8.10 from 3.10. I reinstalled CMake, Make. Then I applied the document from Part Two: Build CARLA. Now, there is no error b2.exe error.

[khemrind-idsi]

@BedirhanKeskin Downgrading python from 3.10 to 3.8.10 was the solution for me. Thanks!

[vini-at-potential]

Same here, had to downgrade from Python 3.10 to 3.8.10 to make it work. I did not try Python 3.9.6 though, so don't know which is the latest python version possible.

[hche8927]

Same here, the issue was likely caused by Python 3.10, installing Python 3.9.9 fixed it for me.

As the screenshot shows, I got the setup error when I was typing "make PythonAPI".
My setting:

• carla: 0.9.13
• Windows 10 (not linux in ubuntu)
• VS: 2019 with additional elements.
• Make: GNU Make 3.81
• CMake: 3.23.0-rc2
• Python: 3.8.8 I'm not sure what causes this error, can anyone help?

Same issue here. Have you found a solution?

I really sorry for my bad english skill first.

I solved this issue by other way.

The bottom line is unzip boost_1_72_0.zip manually and paste it into `boost-1.72.0-source'

make launch or make PythonAPI, processes will create carla/Build/boost_1_72_0.zip. and expanding. When which task done, PowerSheel throw b2.exe error like this.

So i tried b2.exe --help in PowerShell, it throw error 'unable to load boost.build: could not find "boost-build.jam"'

I guess it should be missing files when expanding on PowerShell. and checked downloaded zip file, compare with unziped folder. finally i found some files are missed while exapnding on PowerShell.

That's it. i just unzip boost_1_72_0.zip manually, and it does work.

don't forget excute bootstrap.bat for create b2.exe

[Ja20019]

this issue was caused by Python 3.10, to remove python 3.10 then install python 3.8 to fix it.
