[Buildroot] How-to export cross-toolchain and libraries to a build server?

[Fabrice Mousset | GEOCEPT GmbH]

Dear Thomas,

thanks a lot for your quick reply.
I will follow your advice and use BR2_HOST_DIR to fixe SDK location.
So I will have a quick solution to move the SDK to our build server.

I will also take a closer look at the TODO list, and perhaps I could contribute to buildroot to help integrating a relocatable SDK generation, which will be a very nice and useful feature.
But I think, I will have to learn a lot of thinks about the internals of buildroot before.

Best regards

Fabrice

Just tar the contents of output/host. However, beware that right now the SDK is not relocatable, so you'll have to install it to the exact same location on other machines. In general, the default location in output/host is not very nice, so you can use the BR2_HOST_DIR configuration option to change where the host directory gets stored, and therefore put it for example in /opt/buildroot-sdk/, and then tar this.

Making the SDK relocatable is on our TODO list. There is a list of the issues to fix and some possible solutions at http://elinux.org/Buildroot#Core_Buildroot_infrastructure.

No, the Eclipse support is orthogonal to this. The Eclipse support will only write one line to $HOME/.buildroot-eclipse.toolchains for each Buildroot toolchain that has been built on the system, so that Eclipse cna easily show the available toolchain when the Buildroot Eclipse plug-in is installed.

Best regards,

Thomas
