When I follow the steps in #61, I meet the problems like following, I don't know how to fix it up, maybe someone can help me

I have no specific experience with this problem, but looking at the stack trace, it might be because there's an environment variable containing non-ASCII characters. It looks like SCons has a problem with that.

I am compiling mitsuba in VS2017 as well. I clone the whole project and opened the solution in the build folder. when compiling it I got a different problem, it didn't generate the exe file. does this project from official site not complete or miss some files?

Have you tried this method?

thanks a lot, scons checks all my environment variables(not only path). as soon as I remove all variables with non-ascii character, it compiles well

yes, I tried that, but when I run mtsgui.exe , there is no response at all, I don't know whether it is because the Qt version doesn't match, I had Qt5.13 installed.

I see the qt version is 5.9.1. "dependencies\include\QtCore\5.9.1"
I tried it, but the same question remains.

If you change your Qt version to 5.9.1 and meet the same problem with me. you can see this. #52 (comment) The comment help me fix it out. Just use the Qt... files in your Qt installation path to overwrite the files in the same dir of mtsgui.exe.
