build fails for filter example - no such package

[kjyoti]

I have tried the build according to the steps mentioned in the README. The build fails with the error below

/envoy-filter-example$ bazel build //:envoy Starting local Bazel server and connecting to it...

@kjyoti @kuroneko25 seems like you don't have autoreconf on your machine. Could you let us know the platform you use to build this project? Thanks!

@kjyoti @kuroneko25 Make sure to install the required dependencies and check to see if the issue persists:

Ubuntu

sudo apt-get install libtool cmake automake autoconf make ninja-build curl unzip virtualenv

Mac OS

brew install coreutils wget cmake libtool go bazel automake ninja clang-format autoconf aspell

@dio @catalin-me Is there any way to fix it on windows?
