Hey,


Could you send me the build log?


Thanks

Sorry, the two attachment icons where white on white for some reason, I missed them, but saw them in the web interface (where they show as blue).

At first sight, the problem seems to be that the generated code uses ‘decltype’, which is a keyword in recent versions of C++. I guess your versions of C++ activates C++11 by default.

Better to fix it in the source. I’m downloading a deb9 ISO as we speak to make sure the fix works there. I will keep you posted.

Thanks
Christophe

Maybe it is better to use clang as anyway we use LLVM to build a half?

I’ve successfully built with gcc on other Linuxen. I have finished installing the deb9 VM, but I’m a bit overloaded until at least Nov 7. So not sure I can find the time to check on this problem right now.

Don't worry. It's not a critical thing, maybe I'll add autotools support later myself.

FYI, I’m a big hater of autotools, since they don’t work correctly on macOS (in case there is any error). Hence https://github.com/c3d/make-it-quick.
