If anyone knows why people are suddenly encountering these meschach build errors I'd be keen to know - presumably either the build tools or distro configurations (e.g. environment variables) have...

It isn't just due to this?: > C23 by default: GCC 15 changes the default language version for C compilation from [-std=gnu17](https://gcc.gnu.org/onlinedocs/gcc-15.1.0/gcc/C-Dialect-Options.html#index-std-1) to [-std=gnu23](https://gcc.gnu.org/onlinedocs/gcc-15.1.0/gcc/C-Dialect-Options.html#index-std-1).

Fixing the gcc 14 errors is fairly simple - for example on Nixos ``` env.NIX_CFLAGS_COMPILE = toString [ "-Wno-error=implicit-function-declaration" "-Wno-error=implicit-int" "-Wno-error=incompatible-pointer-types" ]; ``` If you're building manually on a normal...

For the gcc 15 errors try adding something like `-std=gnu17` to the CFLAGS.

Looks like it also needs `-Wno-int-conversion`
