build envoy with bazel,but has error, someone would help me?

[WestEnlarged]

i'm using win10 ,and installed bazel (3.5.0) , then i checkout the code to build master with the envoy doc. It is very confused like this, and i was installed python.

`PS E:\code\envoy> bazel build

[rtttech]

I have the same error, windows10

[yanavlasov]

Did you follow this process to set-up your build environment? https://github.com/envoyproxy/envoy/blob/master/bazel/README.md#windows

@envoyproxy/windows-dev

[sunjayBhatia]

@WestEnlarged @rtttech you will have to Python is installed and on the PATH as described in the linked docs

I would also suggest supplying a target to bazel build e.g. bazel build //source/exe:envoy-static to build the server binary

[WestEnlarged]

@yanavlasov thank you, i forget the
mklink %USERPROFILE%\Python38\python3.exe %USERPROFILE%\Python38\python.exe

the problem has been solved. but the build still failed. It seems MSVS not support the option '-Zc:__cplusplus' , not sure.

i was very confused! then i remove this option, got this:
ERROR: E:/code/envoy/source/extensions/resource_monitors/injected_resource/BUILD:12:17: C++ compilation of rule '//source/extensions/resource_monitors/injected_resource:injected_resource_monitor' failed (Exit 2) bazel-out/x64_windows-opt/bin/include/envoy/common/_virtual_includes/base_includes\envoy/common/platform.h(24): fatal error C1083: Cannot open include file: 'afunix.h': No such file or directory

[sunjayBhatia]

@WestEnlarged what version of the Windows SDK are you on? You will need a version of Windows that is recent enough to include support for Unix Domain Sockets and an SDK that contains that header, we have tested only with VS 2019 and the associated VS Build Tools standalone installs

[WestEnlarged]

i installed vs2019 and using windows 10 sdk(10.0.19041.0). Then i follow the instructions (https://github.com/envoyproxy/envoy/blob/master/bazel/README.md#windows) every step, but failed very sadless.
like this:

maybe i shoud working without windows. what environment are you using for development? @sunjayBhatia

[davinci26]

From the error message it looks like the 'ninja' is not in the path.

In my dev environment I have it separately installed and added on the path.

@sunjayBhatia does ninja come with VS build tools 2019 or does it have to be installed separately?

[sunjayBhatia]

Looks like theres also a path issue in the CMake output there as well: D:\eb\execroot\envoy//D:/tools/...

Ninja comes with VS Build Tools (it is a 32 bit exe so just be aware if you've disabled support for that), just needs to be on your PATH (you can also install it separately if you like but it needs to be on your PATH as described in the setup docs)

[sunjayBhatia]

what environment are you using for development

I have recently been using a Windows Server 2019 host in GCP, doing builds in the envoyproxy/envoy-build-windows2019 container image

[WestEnlarged]

yes, it is. but i not know how to generated "crosstool_bazel.cmake", and i'm sure that i put ninja to the path.
it's msys2's convert path issue probably but i not know how to solve it.
On the bazel's doc, they recommend to use cmd or powershell, but envoy's build must need bash. It's confused.

[sunjayBhatia]

can you give us the output of your environment? Seems like some environment variable may be mangled

[WestEnlarged]

@sunjayBhatia i'm using win10 professional(10.0.18362)

3. i tested the cmake and ninja working after install vs2019.

4. and i download the bazel example code to build. it works.

5. i modify the envoy code .bazelrc , add follows:

startup --output_base=D:/eb startup --output_user_root=D:/tmp startup --windows_enable_symlinks build --enable_runfiles

6. then run the build command in powershell.

bazel build -c opt //source/exe:envoy-static

can catch the follow issue and preivious issues:

ERROR: D:/code/envoy/source/extensions/filters/listener/tls_inspector/BUILD:15:17: C++ compilation of rule '//source/extensions/filters/listener/tls_inspector:tls_inspector_lib' failed (Exit 2) external/boringssl/src/include\openssl/engine.h(1): error C2220: the following warning is treated as an error external/boringssl/src/include\openssl/engine.h(1): warning C4819: The file contains a character that cannot be represented in the current code page (936).

if i modify those files encoding. it report preivious path issue. all of this.

After following the build instructions on a clean install VM, here are my relevant env variables for each shell. Note that when following the build instructions for Windows, you only need to set environment variables in the shell that you want to build in. For me, I invoke bazel in cmd, so I only set up the environment variables in a cmd prompt.

cmd:

BAZEL_SH=C:\Users\Administrator\msys64\usr\bin\bash.exe

msys:

BAZEL_SH=C:\Users\Administrator\msys64\usr\bin\bash.exe
BUILDIFIER_BIN=C:\Users\Administrator\go\bin\buildifier

I can successfully build the envoy binary using:
bazel build --config=msvc-cl //source/exe:envoy-static

FYI this was done on rsmaster a few weeks ago

[WestEnlarged]

I retried but faild, and give up windows. Instead of windows, I trail run building in Alpine (WSL).

I run ./ci/run_envoy_docker.sh './ci/do_ci.sh bazel.dev' , and the output like this. Is code of master has problem? or any other tip with me to fix this?

[sunjayBhatia]

that looks like a download error which should be good to retry

just a word of warning, we don't explicitly test building Envoy in WSL, it may work but there is not validation in CI or otherwise

If youre comfortable with developing in containers, see https://github.com/envoyproxy/envoy/tree/master/ci#on-windows for notes on using the Windows container build image
