missing "the scripts"

GPLv2 and LGPLv2.1 require:

"the scripts used to control compilation and installation"

let's see what we got...

a tale of two TVs

https://github.com/opensource-vizio/5583-OpenSourceCandidate

build and install (Samsung, 1 of 4)

* Building linux
    * Unpack the linux tarball and cd into it.
    * "cp amber.rel.config .config"
    * "make oldconfig" and "make Image"
    * "cp arch/arm/boot/Image ../uImage"

* Building busybox
    * Unpack the busybox tarball and cd into it.
    * "make CROSS_COMPILE=arm-v5t-le-".
    

build and install (Samsung, 2 of 4)

 # unsquashfs -d rootfs rootfs.img
 # rm ./rootfs/bin/busybox
 # cp [path_to_busybox]/busybox ./rootfs/bin/
 # rm -f rootfs.img
 # mksquashfs ./rootfs rootfs.img
 # rm -rf ./rootfs
    

build and install (Samsung, 3 of 4)

1. Connect serial cable to Ex-Link(serial) port.

2. Make folder 'update' in usb memory drive and copy boot.img,
   rootfs.img and uImage files into the 'update' folder.

3. Connect usb memory drive to the usb port of your TV.

4. In the status of unpluged power cable, push 'Shift' key
   and '~'key at the same time, then plug in power cable. 
   After 2 seconds later, press enter key.
   You can find uboot menu in serial message.

5. Press '0' key(in keyboard) and Enter.
    

build and install (Samsung, 4 of 4)

6. Type "bbm usb", then Enter.
     	        [BHPLCD ]# bbm usb
		...
		[BBM:   ]  4 : kernel image    ...  "uImage"
		[BBM:   ]  5 : root file system..."rootfs.img"
7. In step 6, select '4 : Kernel image'.
8. Type "/update/uImage".
		 ......   [ONW:   ]  | IMAGE WRITE FINISHED!
9. In step 6, select '5 : root file system'.
10. Type "/update/rootfs.img".
		 .......  [ONW:   ]  | IMAGE WRITE FINISHED!
    

build? and install? (Vizio, 1 of 2)

#Build Instructions

1. Unzip this zip to a folder in your Ubuntu [22.04] VM

2. Run this command to make the scripts executable
        sudo chmod 755 ./*.sh
	
3. Run each of the four build scripts in this order:
        ./prepForBuild.sh 		
            (after this script, you'll need to change directory \
                back to where the scripts reside)
            (takes less than a minute)
    

build? and install? (Vizio, 2 of 2)

        ./buildApolloLite.sh
            (takes about 3.5 hours to run)

        ./buildBtsound.sh
            (should take about 5-10 mins)

        ./buildFfmpg.sh
            (should take about 1 minute)
		
        ./buildFUR5.1.1-31X_GPL.sh
            (should take about 30 mins)
            (if this errors out within the first few minutes, \
                simply run it again and it should work)
    

cannot "operate properly with a modified version"

statically links "WebSocket client library for Python"

we noted that "there is no information provided for how to cause the relevant third party portions of the application/scpl/bin/manage binary file to operate properly with a modified version of the library"

from LGPLv2.1 text, saying the program "will operate properly with a modified version of the library"

what we want

source code for the missing programs/modules

incompatible license text fixed, "operate properly"

"the scripts used to control compilation/installation"

fix https://github.com/opensource-vizio/5583-OpenSourceCandidate
