Development will be easy. You will be able to setup simple, clean make files to build your applications and then just scp the binaries over to the embedded system and run. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams?

I ran apt-cache show libc6 on my dev machine which shows amongst other things Package: libc6 Priority: required Section: libs Architecture: i Source: eglibc Version: 2.
Improve this question. Not yet, I will certainly give this a try - thanks for the suggestion. Have you tried static linking? You can also setup a chrooted environment with the older glibc version and use it to compile for the embedded system. HristoIliev I have thought about static linking and it may well have to be the way forward. I would really just like to know how to do this issue seems to be cropping up a lot. I am really new to embedded stuff so I am absorbing a lot of info at the moment but not getting much progress.
I will certainly do some research on your suggestion. Add a comment. Active Oldest Votes. Improve this answer. Hristo Iliev Hristo Iliev Many thanks for your answer I will try this first thing tomorrow.
It also gives me some extra keywords to go off and research. Coming from windows it is a real shock to me just how difficult it is to get to grips developing something on linux that will run on a machine configured differently. I cannot believe that there are not more tutorials about this kind of thing online. Thanks again. Standard practice environment setup should still follow: The host machine should have a tool chain setup to cross build applications to the embedded architecture The host machine should have a copy of the full rootfs that exists your embedded device.
This will contain all of the libraries that your cross tools will use to compile applications for the embedded system If you have it setup this way. Can you suggest the tools with which to do this - or an online resource that does so??? I don't know the details of your embedded system. But generally companies will provide a base to work from. For example, Freescale provides ltib which allows you to build or extract functional u-boot, rootfs, kernel, etc for the reference board you bought.
If you are just looking for a tool chain and one isn't provided, you can build it yourself: kegel. Though it sounded like the architecture of your embedded device was the same as your host. So you don't need to cross compile. Yes the architecture is the same. So I basically just need to find a way to extract the file system from my board into my machine, build the necessary libraries and binary on host machine then copy back to the device?
Yes, if a minimal rootfs isn't provided for you. The alternative is you can tar up everything from the base directory of the embedded device and scp that to your host. I recommend working out a clean project tree so you can setup paths sanely.
Douglas Leeder Douglas Leeder Thanks for this suggestion I will certainly explore this option. Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. On Ubuntu With I would rather not intervene manually in system folders to get this header file in. Can it be obtained somehow from the repositories? Update : This seems more a more general problem.
Copying these files from an Ubuntu18 system to your Ubuntu20 system can solve this problem. The link includes the files I copied from my colleague's Ubuntu18 computer, which solved my problem. By the way, the validity period of these files is only 30 days. If someone finds a better file sharing website, they can share the new file link in the answer, thank you! Ubuntu Community Ask!

Improve this question. As a good will I have reported this as bug to pad.
