Hi everyone,

I am trying to build Unreal Engine from source. However I'm encountering this error whenever i am executing following command.

I only included the first part of the output since it keeps repeating itself over all the 193actions.

Even a small point in the right direction is highly appreciated! ;-)

Thanks in advance!

And here are the paths inside my .emscription file.

Is there missing something?

It doesn't seem to be able to find LLVM and clang. Does

/Applications/UnrealEngine/Engine/Source/ThirdParty/HTML5/emsdk/Mac/clang/e1.30.0_64bit/clang++

exist and work when you call it?

Thanks for your reply Alon!

I can confirm clang++ exists within that directory.

However when i call it in the terminal this is what i get:

-bash: /Applications/UnrealEngine/Engine/Source/ThirdParty/HTML5/emsdk/Mac/clang/e1.30.0_64bit/clang++: Permission denied

So it seems you're right. Any idea how to get around this?

Maybe it's a literal permissions issue? Might have been installed without the x bit. Or by a different user?

Allright, I was able to fix it. If anyone else would encounter this problem, use the chmod a+x command (on OS X) followed by the file you want to add 'execution' rights to.

Thanks for your help Alon!

Thank you, Dtec and Alon. I got the same error and the suggested method of "chmod a+x" has help removed the error messages for clang and node.

However, I still got this warning and an remaining OSError: [Errno 13] Permission denied

WARNING root: could not check fastcomp: [Errno 13] Permission denied

I've changed the permission for all the paths listed the error message and from the ~/.emscripten file. But still I cannot remove the error.

Did you change the permission for other files besides the clang and node directories?

Thanks!
