I'm using buildroot to create a rootfs running on my ARM platform. I'd like to have a package manager on my platform to easily install packages, like apt-get in ubuntu. I found opkg, who can be simply added to the buildroot build, but I can't find any information about how to find a repository. Also, reading some stuff on the web about this, I also read that buildroot didn't include a package manager. Isn't opkg a package manager?

Im not sure i've posted in the right location, if you could correct me i'd appreciate it. I have BuildRoot running as my OS, and im trying to run python files on it.

Or just some kind of frontend to fetch packages? I don't really understand what a package manager consist of, and I don't find any information about this. Could someone explain what is really needed to implement that kind of manager, or where to find such informations? Isn't opkg a package manager? Or just some kind of frontend to fetch packages?

It looks like it tries to provide all the features of apt-get. Could someone explain what is really needed to implement that kind of manager, or where to find such information? Package managers provide many different features. As they have evolved, different layers of ease for the end user has been added. Generally, they started in the Linux desktop or server space and have been ported for use in embedded systems.

Some differences; an embedded system is usually single tasked. Firmware Samsung Galaxy S3 I747 4.3. A package management system allows the user to pick and choose what is installed. Often, an embedded system might not want to allow a user to pick and choose packages. Of course, it depends on the applications.

Some package management features, • Building and patching. • Package dependency and hence package database.

• Package migration. • Package specialization. • Automated download • Minimize download time/bandwidth. Rpm, dpkg, ipkg are typically only fulfilling items 1-4. Buildroot doesn't even do this, only item one is really relevant.

The reason is that Buildroot is intended to build software for a fixed system that will never be updated. It doesn't make sense to have a file system with network update and package migration, it there is not network connection or external storage in the device. Also, Buildroot tries to be minimal and these extra features have a cost. Provide a system to create items 1-3, but not the network download. Also, out of the box, it is rather in-efficient in RPM size. Item 4, leads to typical devel and deploy packages. In order to build a library, you need header files to compile dependent packages.

A typical LTIB rpm includes all the header files. It is an easy task to make sub-packages that exclude these headers and man pages, etc. OpenWrt works well for routers, but if you need graphics, sound and other features the packages may not be available. There are various file system builders, but due to the amount of variations, each has costs and benefits. Just as there are many Linux desktop and server distributions, there are many root filesystem builder with different package management options. You have to evaluate the strengths for you application and system. Thanks for your complete and clearfull answer.

I have to correct you on some points: buildroot can be configured to include ipkg/opkg. Huawei Pocket Wifi 2 Unlock Code there. Both of those seems to have 1-5 features you describe above. The hard thing is to find a package repository compatible with the desired architecture. I found one for mine but I feel having a lot of luck for this. Also I agree with you that usually embedded systems would not implement such package management tools. For information, I want to implement it just for development acceleration, I'll remove it for production. – Jul 22 '13 at 9:25 •.

Hi I installed ubuntu 13.10 after its release, a 64-bit version. Before I could get buildroot working, i had to install the 32-bit compatible libc, gcc, g++ etc. Apparently ubuntu 13.10 doesn't support ia32-libs any more. Thus, you have to manually install the required 32-bit packages as follows sudo apt-get install libc:i386 sudo apt-get install cpp-4.8:i386 sudo apt-get install gcc-4.8:i386 sudo apt-get install binutils:i386 sudo apt-get install cpp:i386 sudo apt-get install gcc:i386 sudo apt-get install g++:i386 This list is by no means exhaustive, and is only intended to help anyone out there scratching their heads due to this change in ubuntu 13.10.
