how to install gcc-7.3 or gcc-7.2? #2

Open hmaarrfk opened 5 years ago

hmaarrfk commented 5 years ago

@jjhelmus I've managed to make the first package, toolchain,

but it seems I need a compatible version of libgcc-ng. I can't find the feedstock for that one.

It looks from the notes that you cross compiled that one.

Could you help me get it to the version I have installed in the docker container?? The docker container uses gcc 7.4. I don't really know how to install gcc 7.3 on aarch64

You can see the results of this build process: https://app.shippable.com/github/hmaarrfk/make-feedstock/runs/4/1/console

I just got the rights for Archiconda to use aarch instances on shippable.

It probably has something to do with this: https://github.com/jjhelmus/conda4arm_bootstrap But this seems to be use cross compilers. Something I have no experience with.

hmaarrfk commented 5 years ago

I think my previous thinking was wrong. @jjhelmus had compiled compilers for us and put them in his channel

https://anaconda.org/jjhelmus/repo?label=aarch64_bootstrap

Instead of using the toolchain compilers, I think I am supposed to use the gcc compilers.

Yes, there are GCC 7.3.0 compilers packages in the jjhelmus/label/aarch64_bootstrap channel that can be used. Keep in mind that I created these bootstrap packages on a machine running Ubuntu 18.04 so the compilers require glibc 2.27 or newer. These compilers produce binaries that target glibc 2.17 and therefore the artifacts should work with CentOS 7 and newer distribution (CentOS 6 does not support aarch64).

I'm working on rebuilding the compilers in a CentOS 7 docker container to produce compiler packages that are compatible with broader array of glibc versions.
