            There are two issues here:

            1. Oracle Database is not supported on ARM processors, only Intel. See here: https://github.com/oracle/docker-images/issues/1814
            2. Oracle Database Docker images are only supported with Oracle Linux 7 or Red Hat Enterprise Linux 7 as the host OS. See here: https://github.com/oracle/docker-images/tree/main/OracleDatabase/SingleInstance

            Oracle Database ... is supported for Oracle Linux 7 and Red Hat Enterprise Linux (RHEL) 7. For more details please see My Oracle Support note: Oracle Support for Database Running on Docker (Doc ID 2216342.1)

            The referenced My Oracle Support Doc ID goes on to say that the database binaries in their Docker image are built specifically for Oracle Linux hosts, and will also work on Red Hat. That's it.

            Because Docker provides process level virtualization it still pulls kernel and other OS libraries from the underlying host OS. A Docker image built for Oracle Linux needs an Oracle Linux host; it doesn't bring the Oracle Linux OS with it. Only Oracle Linux or Red Hat Linux are supported for any Oracle database Linux installation, with or without Docker. Ubuntu, Mac OS, Debian, or any other *NIX flavor will not provide predictable reliable results, even if it is hacked into working or the processes appear to work normally.

            "Configuring the trigger failed, edit and save the pipeline again" with no noticeable error and no further details
            Asked 2022-Feb-16 at 10:33

            I have run in to an odd problem after converting a bunch of my YAML pipelines to use templates for holding job logic as well as for defining my pipeline variables. The pipelines run perfectly fine, however I get a "Some recent issues detected related to pipeline trigger." warning at the top of the pipeline summary page and viewing details only states: "Configuring the trigger failed, edit and save the pipeline again."

            The odd part here is that the pipeline works completely fine, including triggers. Nothing is broken and no further details are given about the supposed issue. I currently have YAML triggers overridden for the pipeline, but I did also define the same trigger in the YAML to see if that would help (it did not).

            I'm looking for any ideas on what might be causing this or how I might be able to further troubleshoot it given the complete lack of detail that the error/warning provides. It's causing a lot of confusion among developers who think there might be a problem with their builds as a result of the warning.

            Here is the main pipeline. the build repository is a shared repository for holding code that is used across multiple repos in the build system. dev.yaml contains dev environment specific variable values. Shared holds conditionally set variables based on the branch the pipeline is running on.

            ANSWER

            Answered 2021-Aug-17 at 14:58

            I think I may have figured out the problem. It appears that this is related to the use of conditionals in the variable setup. While the variables will be set in any valid trigger configuration, it appears that the proper values are not used during validation and that may have been causing the problem. Switching my conditional variables to first set a default value and then replace the value conditionally seems to have fixed the problem.

            It would be nice if Microsoft would give a more useful error message here, something to the extent of the values not being found for a given variable, but adding defaults does seem to have fixed the problem.

            Configuring compilers on Mac M1 (Big Sur, Monterey) for Rcpp and other tools
            Asked 2022-Feb-10 at 21:07

            I'm trying to use packages that require Rcpp in R on my M1 Mac, which I was never able to get up and running after purchasing this computer. I updated it to Monterey in the hope that this would fix some installation issues but it hasn't. I tried running the Rcpp check from this page but I get the following error:

            ANSWER

            Answered 2022-Feb-10 at 21:07
            Background

            Currently (2022-02-05), CRAN builds R binaries for Apple silicon using Apple clang (from Command Line Tools for Xcode 12.4) and an experimental build of gfortran.

            If you obtain R from CRAN (i.e., here), then you need to replicate CRAN's compiler setup on your system before building R packages that contain C/C++/Fortran code from their sources (and before using Rcpp, etc.). This requirement ensures that your package builds are compatible with R itself.

            A further complication is the fact that Apple clang doesn't support OpenMP, so you need to do even more work to compile programs that make use of multithreading. You could circumvent the issue by building R itself and all R packages from sources with LLVM clang, which does support OpenMP, but this approach is onerous and "for experts only". There is another approach that has been tested by a few people, including Simon Urbanek, the maintainer of R for macOS. It is experimental and also "for experts only", but seems to work on my machine and is simpler than trying to build R yourself.

            Instructions for obtaining a working toolchain

            Warning: These instructions come with no warranty and could break at any time. They assume some level of familiarity with C/C++/Fortran program compilation, Makefile syntax, and Unix shells. As usual, sudo at your own risk.

            I will try to address compilers and OpenMP support at the same time. I am going to assume that you are starting from nothing. Feel free to skip steps you've already taken, though you might find a fresh start helpful.

            I've tested these instructions on a machine running Big Sur, and at least one person has tested them on a machine running Monterey. I would be glad to hear from others.

            1. Download an R binary from CRAN here and install. Be sure to select the binary built for Apple silicon.

            2. Run
