Error: File not found – The problem with using absolute paths.

While attemtping to add the Lionheart governor to my previously built kernel, I ran into an interesting problem:

[CODE]
firmware/audience-es325-fw-eur.bin.gen.S: Assembler messages:
firmware/audience-es325-fw-eur.bin.gen.S:5: Error: file not found: /home/alaskalinuxuser/Documents/projects/phones/compile/cm13/kernel/samsung/jf/firmware/audience-es325-fw-eur.bin
make[3]: *** [firmware/audience-es325-fw-eur.bin.gen.o] Error 1
make[2]: *** [firmware] Error 2
make[2]: *** Waiting for unfinished jobs….
[/CODE]

The file was right where it was supposed to be. I looked it over six times. It was right there. Then I realized the problem. It wasn’t right there, it was right here:

/home/alaskalinuxuser/Documents/projects/phones/compile/cm13-working/kernel/samsung/jf/firmware/audience-es325-fw-eur.bin

See the difference? It took me a minute as well. When I made a sucessful build of CM13, I then changed the folder to “cm13-working” to make it easy for me to distinguish which folders had good builds in them, and which folders were still a work in progress. Might sound strange, but I build for about 6 different roms in a round robbin sort of style, so a simpleton like myself can quickly become confused.

Ordinarily, this would not be a problem. Make, the program used to “make” things, is pretty smart, and usually all of the paths are dynamic, changing to the current folder. What had happened, however, was that somewhere along the line, I had a problem with a dynamic path, and as a quick and simple fix, I edited the file to have an absolute, or full, path. So, now that I had taken away the dynamic ability, the folders have to retain their original name to keep all of the files right where they are supposed to be.

Long story short, fix your dynamic paths if they have an error. If you use an absolute path, be sure you don’t ever rename or move anything. Ever. Or at least take good notes so you know what to change.

Linux – keep it simple.
