dyld: warning: could not load inserted library './assets/malloc.dylib'

[Florian-A]

Hello guy.

I clone my repo in the goinfre and i started make command and ./run_test.

I have this message on ft_striteri:

dyld: warning: could not load inserted library './assets/malloc.dylib' into hardened process because no suitable image found. Did find: ./assets/malloc.dylib: code signature in (./assets/malloc.dylib) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed. ./assets/malloc.dylib: stat() failed with errno=1

When i restart ./run_test this message vanish.

My ft_striteri :

#include "libft.h"

void    ft_striteri(char *s, void (*f)(unsigned int, char*))
{
    unsigned int    i;

    if (!s)
        return ;
    i = 0;
    while (s[i])
    {
        (*f)(i, &s[i]);
        i++;
    }
}

Thanks for your work !

Hello, I am working on Libft and have the same problem. Could you please tell me how to solve it? Is it some problem with my functions?

I faced this issue too. After reading a bit about arm64e in macOS, I managed to fix it.

In Makefile, look for the definition of DYLIBFLAG variable:

ifeq ($(OS),Linux)
    DYLIBFLAG = -fPIC -shared -ldl
else
    DYLIBFLAG = -dynamiclib
endif

Update DYLIBFLAG for macOS from -dynamiclib to -dynamiclib -arch arm64e:

ifeq ($(OS),Linux)
    DYLIBFLAG = -fPIC -shared -ldl
else
    DYLIBFLAG = -dynamiclib -arch arm64e
endif

The new Makefile should compile assets/malloc.c into assets/malloc.dylib correctly, which you can verify:

$ file assets/malloc.dylib
assets/malloc.dylib: Mach-O 64-bit dynamically linked shared library arm64e
