Doesn't work on MacOS Montery 12.2.1

[dPowNextdoor]

Overview

When running any command (regardless of type given in any ReadMe file, blog, etc.), no executable is made anymore like it was in the older versions of Mac OSX. Nothing is produced except random (non-executable) files in the same tar-extracted directory, not in /usr/bin/, /opt/<dir>/, etc. so there is no longer any way to execute oneko from the terminal.

Commands attempted

clang -Wno-parentheses -std=c11 -pedantic -D_DEFAULT_SOURCE oneko.c -o oneko -lc -lm -lX11 -lXext

clang -Wno-parentheses -std=c11 -I/opt/X11/include -L/opt/X11/lib -pedantic -D_DEFAULT_SOURCE oneko.c -o oneko -lc -lm -lX11 -lXext

C_INCLUDE_PATH="/usr/X11R6/include" LIBRARY_PATH="/usr/X11R6/lib" clang -Wno-parentheses -I/opt/X11/include -std=c11 -pedantic -D_DEFAULT_SOURCE oneko.c -o oneko -lc -lm -lX11 -lXext

Details

Specifically with the -I[...] -L[...] options, I get the error:

oneko.c:745:5: error: implicit declaration of function 'pause' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
    pause();
