Could you please take a look what went wrong, the CI output does not give a clue

Please resolve these regressions, see windows linux osx log.

Not sure I get it. Looks like there is no bazel on OSX. Is it ok? Then what the vcpkg_find_acquire_program(BAZEL) for?

As for Win/Lin.

Is there failed command out put somewhere?

@kreuzerkrieg I've added bazel in OSX.

@kreuzerkrieg I've added bazel in OSX.

Thanks!
Any idea what is the meaning of Win/Lin error message?

[JackBoosY]

@kreuzerkrieg

    Command failed: bazel build //ryu
    Working Directory: C:/vsts/_work/4/s/buildtrees/ryu/src/v2.0-3429a290df

Make sure the command is correct.

@kreuzerkrieg The tensorflow port has an example on how to use bazel in vcpkg. I remember you had to use /// instead of // in bazel build on Windows for the targets but I forgot why.

AFAIR, tensorflow just checks if bazel installed, as for build it executes some python script. I will check the /// vs // once I get to Windows machine. However I dont get why it fails on Linux, looks like it is running fine on my Ubuntu machine

[kreuzerkrieg]

Nailed it.
Took a clean machine to test the port. It failed the exact way it failed in Azure CI.
The reason the vcpkg_find_acquire_program(BAZEL) does not deliver. It does not install bazel on the target machine. Once installed manually the port completed successfully

[JackBoosY]

@kreuzerkrieg You should use BAZEL downloaded by vcpkg, please see the example.

LGTM, failures seem unrelated

/azp run

Alright, thanks @kreuzerkrieg ! This is a great addition :)
