I also found this "amalgamate" script on GitHub, intended to allow creating such amalgamations from C/C++ projects:

https://github.com/rindeal/Amalgamate

Which seems interesting, however when I tried the FreeType example, there seemed to be some preprocessing issue, such that some function definitions are conditionally excluded even though they are called later. I didn't have the time to find out if this was an issue in the original code or if the amalgamation script introduced it.

In any case, such single-C programs are very useful for quickly testing tools, so having more of them would be great.

I'm not a C programmer, but I have heard of amalgamation, and I wonder why a standard workflow to create a single compilation unit from multiple source files isn't more straightforward.

Because C is stuck in the dark ages.

Textual preprocessors are evil.

That took a few minutes to make it work on newer macos.
