nodejs 26.8.2 fails to build with clang/LLVM

Version

26.8.2

Platform

Linux (Gentoo with LLVM profile)

Subsystem

LIEF (or forzen)

What steps will reproduce the bug?

1. Build nodejs version 26.8.2 with clang
2. Observe failure

How often does it reproduce? Is there a required condition?

Always while building with clang

What is the expected behavior? Why is that the expected behavior?

Successful build with clang

What do you see instead?

Build failure while building with Clang

Additional information

I think this is due to stricter include requirements on clang
I was able to build by adding #include <functional> in deps/LIEF/third-party/frozen/include/frozen/map.h

Inizia da deps/LIEF/third-party/frozen/include/frozen/map.h, quindi riproduci la build di Node.js 26.8.2 su Linux con Clang. Controlla la dipendenza dalla libreria standard riportata nell'errore e verifica che la build venga completata correttamente con Clang senza gli errori relativi a std::less non definito.
