Re: [EXT] [vpp-dev] cross-compilation support

FYI, I have recently started to use the buildx experimental feature in docker (>=19.03). it looks interesting as it is designed on purpose for building multi-platform images, and manages to reuse the same dockerfile for as many platforms as supported by qemu (in theory). I'm not quite sure yet ab

I slightly modified my patch, so it builds both native packages and cross packages out of same makefile. Native: $ make pkg $ ls -la build/native-release total 99352 drwxrwxr-x 3 damarion damarion 4096 Oct 31 20:00 . drwxrwxr-x 10 damarion damarion 4096 Oct 31 19:55 .. drwxrwxr-x 22 da

Re: [vpp-dev] cross-compilation support

Nobody requires you to use docker, you are free to pass right arguments straight to the cmake. All the stuff in build-data, build-root, build/ is optional, and it is there to help developers to stage workspace and create packages but VPP can be built as simple as: mkdir build cd build cmake

Re: [vpp-dev] cross-compilation support

I mean to call out the use of docker/qemu. In order to allow for this the user has to have extra privileges. As I mentioned, locally we use docker for building, I like it, it's a nice tool; however, my personal opinion is that it seems wrong to require docker and/or qemu for compiling an open s

Re: [vpp-dev] cross-compilation support

Requiring root privileges for building software is pretty atypical and limiting, even for x-compiling. Thanks, Chris. > On Oct 31, 2019, at 12:45 PM, Damjan Marion via Lists.Fd.Io > wrote: > > > So what people think about following approach for cross-compilation: > > Patch: https://gerrit.f

[vpp-dev] cross-compilation support

So what people think about following approach for cross-compilation: Patch: https://gerrit.fd.io/r/c/vpp/+/23153 At the moment this is just to show idea, so it works only for x86-to-x86 and between ubuntu versions only but it can be easily extended to sce
