Subject: [PATCH] main.c: rework logic to find def1, def2 and def3 files
|
||||
|
||||
The current logic to find def1, def2 and def3 first tries to find them
|
||||
in the local directory, and if they are not available, find them in
|
||||
/usr/share.
|
||||
|
||||
However, this doesn't work if rpiboot and its related files are
|
||||
installed, but not in /usr. In order to address this use-case, this
|
||||
commit reworks the logic to find the file path.
|
||||
|
||||
A new function, getfilepath() is created. If the requested file is
|
||||
available in the current directory, it is used. If not, then the path to
|
||||
the file is inferred from the location of the currently running
|
||||
program. I.e if we run /home/foo/sys/bin/rpiboot, then we will search
|
||||
def1 in usbbootcode.bin in
|
||||
/home/foo/sys/bin/../share/rpiboot/usbbootcode.bin.
|
||||
|
||||
This continues to address the case of an installation in /usr, while
|
||||
allowing installation in other locations as well.
