I get the error below when I try to build on Ubuntu. I'd appreciate any help! Thanks!

[essej]

What version of gcc is that?

[chigkim]

gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

[essej]

Go ahead and do what the compiler suggests and insert a #include <mutex> near the top of deps/aoo/lib/src/sync.hpp and then try the build again... let me know!

[chigkim]

That worked! Thanks!

[tcconway]

Can confirm this worked for me as well. Thanks!!

[essej]

I’ll make the fix in the repo shortly

[essej]

This fix has been made in the latest master...
