Yeah, not sure why it happens yet. Also reported here: JakWai01/lurk#48

Maybe try without leading slash 👀

[orhun]

This will be fixed in #48 :)

@godzie44 ! did it fix for you? I have the same issue with a simple hello world program in C. I simply ran cargo run install --force after pulling the latest changes. Then I ran binsider hello.elf and it did not work. I also tried absolute paths, but I get the same error. I am assuming the changes are incorporated in the binary.

I was too confident about the fix 😅 The issue seems to be still there and I'm even more puzzled by it now. It apparently works for some files and not for others. Can you share the file you are trying this with?

[orhun]

Btw it fails for this function:

pub fn ptrace_init_options(pid: Pid) -> nix::Result<()> {
    ptrace::setoptions(
        pid,
        Options::PTRACE_O_TRACESYSGOOD | Options::PTRACE_O_TRACEEXIT | Options::PTRACE_O_TRACEEXEC,
    )
}

I guess either the pid is not available at that time or something wrong with the permissions / file type. Still investigating...

@orhun I am on phone right now, but this was the source code.

#include <stdio.h>
int main() {
   // printf() displays the string inside quotation
   printf("Hello, World!");
   return 0;
}

I then compiled it with gcc -o hello.elf hello.c. My computer details - Ubuntu 22.04 amd64.
Finally, binsider hello.elf.

Thank you for looking into it!

[godzie44]

Looks like this dont fix for me too :(

I'm quite puzzled by this, @JakWai01 any ideas? 👀
