Compiling for Chromebooks with Crouton

I currently have an Asus c300 chrome book. Since it doesn't have the old boot, I use crouton to get a more standard command line environment. I was able to install gcc very easily in a chroot environment. It works very well under chroot.

Since the underlying hardware is the same, I thought the resulting executable should work for the chromebook, without me in the chroot environment. If that's true, I thought I could go into the chroot environment, compile whatever program I want / need, and exit back to the normal environment and use it.

I tried this with a simple world program. When I tried to run the executable, I got the following error:

bash: ./a.out: Permission denied.

I tried to run it with sudo and I get a similar error:

sudo: unable to execute ./a.out: Permission denied.

I even used su to login as root and I still couldn't run the program (got the first error).

I thought su / sudo would override any permission restrictions. But apparently this is not the case on Chromebooks.

What am I missing? Is this what I want to make possible?

EDIT: The file permission is already set to 777.

You may just need to change file permissions or check file ownership. The umask determines the weather, and not the generated file gets run permissions by default. What does -ls -lat show in the file?

Also try running



chmod +x ./a.out

You can find out more about the error with the strace

Usage: command
strace ./a.out

and check the output.
I believe you have env (path and LD_library_path)

u chroot

.
