Envoy: Build: bazel build failed in network filters

Created on 27 May 2019 · 16Comments · Source: envoyproxy/envoy

I am trying to build envoy latest code using bazel.

I have installed all the required dependencies and then executed
bazel build //source/exe:envoy-static

Got below error:

/home/i309801/Desktop/envoy/source/extensions/filters/network/kafka/BUILD:92:1: C++ compilation of rule '//source/extensions/filters/network/kafka:serialization_lib' failed (Exit 1) envoy_cc_wrapper failed:

@Satvindar seems like you can try to use clang and clang++ from llvm-8 to compile it. As you have mentioned that you have it in your machine (assumed it is installed at /usr/lib/llvm-8).

$ export PATH=/usr/lib/llvm-8/bin:$PATH
$ export CC=clang
$ export CXX=clang++
$ bazel build //source/exe:envoy-static

There was a general build breakage that was fixed today, so closing for now. If you are still having an issue, can you give more details about your platform and the environment and re-open?

jmarantz on 28 May 2019

I took the latest code today and facing same error. Hence reopening this issue.
Further Details:
Ubuntu 16.04 LTS
clang version 8.0.0
Bazel version 0.25.0
go version go1.12.5 linux/amd64

Let me know if you need further details.

Satvindar on 29 May 2019

I am not able to re-open this issue .

Satvindar on 29 May 2019

Can you attach the complete output of your bazel command?

Target //source/exe:envoy-static failed to build

Satvindar on 29 May 2019

Thanks. I am wondering if this is specific to the Kafka extension or if you can't compile anything on your machine.

Can you try

bazel test //test/common/....

and see if that works? Note that all the developers seem to be able to build no problem, so I'm not sure what's different about your system or setup. clang 8 seems reasonable to me.

jmarantz on 29 May 2019

As another data point, I get this while running tools/bazel-test-docker.sh //test/integration:hotrestart_test on master

bplotnick on 30 May 2019

@jmarantz it worked !! Now all 168 tests passed.
But Bazel build still fails with same error as mentioned previously. Anything else we can do?

Satvindar on 30 May 2019

@bplotnick i tried the command you shared, build failed for me.

Satvindar on 30 May 2019

Sorry, did you try to clean it up and rebuild? like bazel clean --expunge

dio on 30 May 2019

@dio now i got different error:

@Satvindar Ah, that's true. Since this https://github.com/envoyproxy/envoy/pull/6564 is merged we no longer have that c_str() for HeaderString.

envoy (master): git log -S "c_str" include/envoy/http/header_map.h commit 3a596a4b0f8a8c3e60ff6240508a1d7395a9bacd Author: Dan Noé <[email protected]> Date: Tue Apr 16 14:29:29 2019 -0400 Remove HeaderString::c_str() and migrate callers to getStringView() (#6564)

Do you think you can help us to submit a fix for that? It is in this line: https://github.com/envoyproxy/envoy-filter-example/blob/master/http-filter-example/http_filter_integration_test.cc#L39

And seems like this is not related to your first question. I'll close this 🙂.

dio on 1 Jun 2019

@dio Yes, I modified the code and its working.
I will create a PR for this change and will add you as a reviewer.
Thanks :)

Any idea to fix the building error?
