Struggling with include path on macos

[bentxt]

Hi,
After running a simple transformation example to make sure cake runs, I'd like to take it a little bit further and run an example with includes, like this one here:

#include <stdlib.h>
#include <stdio.h>

int main() {
    int n = 2;
    int m = 3;
    int (*p)[n][m] = malloc(sizeof * p);

    printf("%zu\n", sizeof(*p));

    free(p);
}

with include from Apple SDK

when I use this path in 'cakeconfig.h':

#pragma dir "/Library/Developer//CommandLineTools/SDKs/MacOSX14.4.sdk/usr/include"

I get this error:

./cake  -target=c11 const.c
Cake 0.9.17
../cake/src/const.c
/Library/Developer/CommandLineTools/SDKs/MacOSX14.4.sdk/usr/include/sys/_types.h:55:25: error: expected TK_SEMICOLON [E970]

with include from clang

when I use this path in 'cakeconfig.h':

#pragma dir "/usr/local/Cellar/llvm/18.1.8/include/c++/v1"

I get this error:

./cake  -target=c11 const.c

I admit and I'm a little bit sorry for not having a full understanding of what going on here, but still maybe somebody can help.

thanks

Type __int64_t is not recognized by cake.
In such cases I generally clone the compiler, in this case I can add __int64_t. (I guess clang has it on mac)

The workaround for now it define it on cake config.

typedef long long __int64_t;

In general MacOS is not tested.

OBS:
VLAs
int (*p)[n][m] = malloc(sizeof * p);

Are not implemented yet.

thanks alot for your help?

Do you think it would be possible to ignore includes all together?

I was planning to create independent header files for cake.

I started here
https://github.com/thradams/cake/tree/main/src/include
but I didn't finished.

The advantage of independent headers is that cake would always be working, specially
for standard code. It could help someone that just want to try cake.

The disadvantage is that some not standard headers could be missing.

If you are planning to do basic tests you can create the headers with the declarations.

The online version
http://thradams.com/cake/playground.html
has it own headers and can help you to write your headers.

For instance

http://thradams.com/cake/playground.html?code=I2luY2x1ZGUgPHN0ZGlvLmg%2B&to=-1&options=-E

The problem of this method is that is removes macros.

The headers files used by the web version are inside the code at

https://github.com/thradams/cake/blob/main/src/fs.c

So ideally I should have the cake "includes" and use the same files for the web version.
(C23 #embed could be useful for that )
