@Mo47 Omega2 has no HDMI support.

Android does have support for MIPS, but I'm not aware of anyone who has tried this on an Omega.

@optech we're always happy to help, I hope you can complete your work successfully.

@optech Just step line by line through the script, it's not that complex, it's just copying files to our packing folder in the structure we need the files placed on the target system. Then running a few command to create the files required for an opkg repository and signing them using usign.

The structure of the directories is the key to the building of the package. The cool parts are in the CONTROL directory where there are 4 files that get executed depending on what opkg is doing, ie before installing your package (CONTROL/preinst), after installing your package (CONTROL/postinst), before removing your package (CONTROL/prerm) and after removing your package (CONTROL/postrm)

The final ipk will be in the "repo" directory

@optech 2 points to note.

1. The script uses the build system scripts to create the final package, this script just makes it easy for me to copy the required files into the correct directory structure. You can see towards the end of the scripts ~/source/scripts/ipkg-build and ~/source/scripts/ipkg-make-index.sh

2. You need to sign your packages, so if you look at the section towards the end with ********************* this I have masked out my public and private keys. You need to create these using usign package. You can install usign like so:

git clone https://git.openwrt.org/project/usign.git
cd usign
cmake .
make
sudo make install

Then use usign to create your keys. I'll leave you to look at that.

@optech ok sorry I thought you had added the package to menuconfig and were compiling that way. I haven't been following closely as @tjoseph1 has been doing a lot to help out.

Making an ipk is not well documented, well not that I found when I was trying to learn how to manually make them. So I made a script to create the ipk for my custom package I build outside of the build system. I need to clean out some proprietary stuff out of my script then I will post it here in a short time.

@optech If you have set chirpstack in make menuconfig to M the ipk will be in <source>/staging_dir/packages/ramips

I would be interested to know if transferring the package to your earlier 19 system gives you the same error as I suspect this may be an issue related to the included libs.

@optech Have you checked that the make file is not redefining those exports?

@kottes Please create a new thread for this question, this thread is 3 years old. I'll answer on the new thread.
