cjit version Temp dir is a file/missing stdio.h on MacOS

[fhunleth]

I'm trying out the cjit v0.18.2 release for MacOS/ARM64. The donut.c example worked perfectly. I'm getting a couple errors when running life.c:

$ cjit life.c
cjit version Temp dir is a file, cannot overwrite: %s (c) 2024-2025 Dyne.org foundation
life.c:1: warning: Ignoring unknown preprocessing directive #!
life.c:2: error: include file 'stdio.h' not found
cjit_exec: TCC linker error
Library functions missing.

I'm on MacOS Sequouia 15.4.

Building cjit from source runs life.c just fine, so I wonder if something changed on CI to break the pre-built versions.

Hi! is stdio.h created in the temp dir? sounds strange as the system one should be used. remember to delete the temp.dir before every try with a different build!

Thanks for the response! I deleted all my /tmp/cjit-* directories. Running the cjit-Darwin-arm64 binary from the releases page, I get a temp directory that looks like this:

/tmp/cjit-
├── include
│   ├── float.h
│   ├── stdalign.h
│   ├── stdarg.h
│   ├── stdatomic.h
│   ├── stdbool.h
│   ├── stddef.h
│   ├── stdnoreturn.h
│   ├── tccdefs.h
│   ├── tgmath.h
│   └── varargs.h
└── libtcc1.a

Just to be super clear, building from source works great for me. This is a cool tool.

is the dir name literally cjit- ?!
if Yes then I guess there are more things going wrong and I really need to ask a friend to borrow a machine to try out myself .. however also stdio.h is missing from there, not sure system has it somewhere and usable.

Yes, the name is literally cjit-. I think it's a CI issue, though.
