execv() failed: No such file or directory

[Ana06]

I have installed edb in a VM with openSUSE Leap 15.2 and I am not able to open an executable ELF 64-bit LSB shared object, x86-64. Both the File-> Open and the --run option raise the following error: Failed to open and attach to process: execv() failed: No such file or directory.

The executable works when running it without edb and attaching to it also works fine.

This doesn't seem related to https://github.com/eteran/edb-debugger/issues/741 as I am running a 64-bit executable in a 64-bit system.

Could you run EDB as follows and post the console output?

strace -feexecve ./edb --run /path/to/your-program

[10110111]

Oh, wait... do you actually have /usr/bin/xterm? If not, try disabling Open a terminal ... option in Preferences_→_Debugging.

Thanks for the fast answer @10110111!

I do have /usr/bin/xterm.

[pid 40509] execve("/home/flare/Desktop/find_the_best_fishing_spot/find_the_best_fishing_spot", ["/home/flare/Desktop/find_the_bes"...], 0x7ffe5c673328 /* 96 vars */) = -1 ENOENT (No such file or directory)

So, the kernel says it can't find a file. This may be a shared library required by the executable. What does the following command say?

ldd /home/flare/Desktop/find_the_best_fishing_spot/find_the_best_fishing_spot

[Ana06]

@10110111 Yes, the required shared library is in a .lib directory in the same directory as the executable. This way it is used when running the program from the console.

[10110111]

How exactly do you run the executable—right from opening a terminal? Do you set LD_LIBRARY_PATH for it to search the .lib directory?
