I see https://pkgs.alpinelinux.org/package/edge/main/x86/gtest-dev which looks like it should resolve the dependency.

This gtest-dev package doesn't contain gmock, and gmock is not provided in alpine package repository.

Since gmock requires to be built with gtest source, I think it's not easy to coexist source built gmock with binary installed gtest.
(Patching CMakeLists.txt of gmock might enable to build it using binary installed gtest. I would like to try it.)

@tfoote I changed it to use alpine package version of 'gtest' and source rosdep version of 'google-mock'.
(It would be better to register google-mock to upstream apk repository in near future.)

Related, it we can probably go ahead and merge this as is if it's working. But for greater maintainability and better use experience it would be great to submit this upstream for packing.

We've found that source rosdeps generally end up being more work than their worth. I thought we'd officially deprecated them but I can't find a reference. But either way they're strongly discouraged. If you've tested them as working we can merge them for now until a better solution is available.

I agree that using source rosdeps lacks maintainability pretty much.
Registering them to the upstream package repository would be necessary. But until completing them, keeping source rosdeps would be helpful for testing.

Currently, released versions (non 'edge' version) of alpine repository lack a lot of necessary packages.

e.g. poco-dev was registered at April 2017 and only available at edge/testing repository at now. I have to understand package life cycle in Alpine well.
(openssl1.0-dev, sbcl and py-coverage are also only in edge.)

So, I think I should define package names for each alpine release versions.

I commented package availability information of the packages which is not provided in Alpine v3.5 (oldest currently supported release).

Using openssl may cause conflict with libressl.

So, I think I should define package names for each alpine release versions.

Since FdoDetect in rospkg uses full version including patch version, to specify package name for each Alpine release, rosdep/base.yaml should be like:

libssl-dev:
  alpine:
    3.8.0: [openssl1.0-dev]  # 'edge' has same os_version with latest release.
                             # **it works on edge but not on 3.8**
    3.7.0: [openssl-dev]
    3.6.2: [openssl-dev]
    3.6.1: [openssl-dev]
    3.6.0: [openssl-dev]
    ...

I guess there is no nice way to support non-edge Alpine version at this moment. (any idea?)
I would like to keep os_version not specified for alpine.

since Alpine Linux recommends to use libressl instead of openssl (https://bugs.alpinelinux.org/issues/4970)

@tfoote I think it is ready as a starting point for discussing and testing ROS on Alpine Linux.
Please take another look.

tfoote

To get started we could only support the current edge and newer for testing. And once edge becomes a release it could be the low water mark. I'm assuming that coverage will grow.

Note that there are things like '*' syntax you can use to make different version simpler, but in general I'd suggest the low water mark will be a better approach in the long term until things change above that point there's no need to define support for older versions that are known not supported.

I'd also encourage you to push hard on getting upstream to package the things that are currently installed from source too. The source rosdeps will make things much more painful in the long run.

at-wat · 2018-07-27T04:48:26Z

@tfoote Thanks for your comments. I'm learning the packaging system of Alpine. I'll start working to register them to the upstream. Also, I'd like to start a discussion at the discourse toward enabling all ROS features on Alpine.

I have found one mistake that python must be python2-dev, not python2.
I'll quickly fix it.
