How to compile native extension with C++11 features? (DEF-2594) (SOLVED)

[sergey.lerg]

I can highly recommend https://godbolt.org/ for testing

That’s an amazing tool! Thanks to it I now understand that there is a deeper problem. Turns out x86 gcc optimizes the string hashing without even blinking, but arm gcc seems to be failing no matter what optimization level is chosen. That’s disappointing, if I don’t find a way I will have to change the code.

We have now released a fix giving you better feedback from the build server if you use tabs instead of spaces in ext.manifest files.

Another build error for Android showed up. “Build failed: Failed to copy classes.dex”.
Wasn’t there before.

A work in progress for the Android packaging?

[Mathias_Westerdahl]

Hmm, I’m looking into it!

EDIT: The classes.dex issue was found and fixed and we should be able to restart the build server some time during the day.

EDIT 2: We have now restarted the server and I’ve just verified that the fix is in. Test it by changing something in your code (to make it ignore the local cache, which is located at “project_name/.internal/cache/.buildcache”)

[sergey.lerg]

Just tested, the build error has gone, thanks!

[britzl]

As for the final linker error, it seems we actually had a rogue “#include <map>” in our code, and they’ll clash. I’ve added ticket DEF-2594 for this.

DEF-2594 was resolved in Defold 1.2.102.
