build failed in Archlinux

Follow the instruction on: https://github.com/zmap/zmap/blob/main/INSTALL.md , I can build zmap source code without ja4tscan success. But when I run bash build.sh to add ja4tscan feature to zmap, I get Error:

You can now run python3 ja4tscan.py

It's seem that gcc 14 not support this kind of pointer or other cause? I'm not sure because I'm not particularly proficient in writing C code, I would greatly appreciate your generous assistance :)

For guys who might meet the same problem. I build success by change gcc14 to gcc13, with follow step:

1. install gcc13 pacman -S gcc13
2. set CC before run cmake in file build.sh

   export CC=gcc-13
   export CXX=g++-13
   cmake -DEXTRA_PROBE_MODULES=probe_modules/module_ja4tscan.c && make

Of course, another method is set CMAKE_C_COMPILER flag.

cmake -DEXTRA_PROBE_MODULES=probe_modules/module_ja4tscan.c -D CMAKE_C_COMPILER=gcc-13  && make
