execv() failed: No such file or directory
Ana06 opened this issue · 7 comments
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 #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
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.

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
@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.
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?
Closing due to lack of feedback. Please re-open if the problem persists.
