I was trying to get my first Hello World device driver program to compile.
First, I compiled a stable Linux kernel, booted it via GRUB, and then proceeded to run the Makefile to compile the hello.c module on my Desktop.
However, by mistake I omitted the path to my Desktop where the source code of my hello.c module was located. Instead I typed:
$ make -C /lib/modules/4.1.6myver2+/build modules
where 4.1.6myver2+ is my Linux compiled Kernel version.
The output is copied below, and it seems to be compiling and building the source code files either in my /lib/modules/Kernel/ folder, or in my copy of the Kernel source code residing in the folder linux-stable, or both.
After a few seconds, I pressed Ctrl+C to interrupt it.
My question is, what do I do to undo the damage this may have done? Has it done anything to the lib/modules/KernelVersion folder, or has it only changed the linux-stable folder. I am running out of space on my VM, so if it built any *.o or *.ko files, I would like to delete it. Thanks
