Question 1

How do I compile multiple files with c?

Accepted Answer

For CLI usage, enclose files and flags in quotes as the first argument, like 'c "main.c helper.c -Wall"'. In shebangs, append files and flags before '--', e.g., '#!/usr/bin/c file1.c file2.c -lm --'.

Question 2

c vs tcc -run: which is better?

Accepted Answer

c is compiler-agnostic and works with any compiler via $CC, offering caching and shebang support, while tcc -run is tied to TCC's optimizations. c is more flexible but adds a layer of abstraction.

Question 3

Can I use c for C++ projects?

Accepted Answer

Yes, c handles C++ files by default. Ensure your $CC variable points to a C++ compiler like g++ or clang++, and use appropriate file extensions (.cpp, .cc).

Question 4

How to set up caching in c to make it faster?

Accepted Answer

Set environment variables C_CACHE_SIZE for cache size (default 5 MB) and C_CACHE_PATH for location (default $TMPDIR/c.cache). Use 'c --clear-cache' to clear it manually.

Question 5

Is c suitable for large C projects?

Accepted Answer

No, c is designed for small scripts or quick tests. For large projects, use dedicated build tools like Make or CMake to handle dependencies and incremental builds.

Question 6

How do I debug a program run with c?

Accepted Answer

c doesn't include debugging tools. Compile with debug flags (e.g., -g) via the CLI or shebang, then use a separate debugger like gdb on the cached binary.
