Error when building gRPC PHP Plugin on CentOS 7

[jis...@wepay.com]

Hi,

I am trying to follow the steps outlined https://grpc.io/docs/quickstart/php.html to install gRPC and protobuf for PHP on CentOS 7 but I am running into an error on when I am trying to build the PHP Protoc Plugin.

I am installing the gRPC PHP extension and Protobuf Runtime library via PECL. I am using gRPC version 1.6.0 and Protobuf version 3.4.0 as these are compatible according to the documentation.

The error I get when I to run make grpc_php_plugin inside the grpc directory is:

[AUTOGEN] Preparing protobuf

configure.ac:94: error: possibly undefined macro: AC_PROG_LIBTOOL

      If this token and others are legitimate, please use m4_pattern_allow.

      See the Autoconf documentation.

autoreconf: /usr/local/bin/autoconf failed with exit status: 1

make: *** [third_party/protobuf/configure] Error 1

I have tried to rerun after installing libtool and rerunning the command gives the following error (same error occurs even without installing libtool and rerunning):

[MAKE]    Building protobuf

checking whether to enable maintainer-specific portions of Makefiles... yes

configure: error: cannot find install-sh, install.sh, or shtool in "." "./.." "./../.."

make: *** [/grpc/libs/opt/protobuf/libprotobuf.a] Error 1

Has anyone seen this error before in PHP and can give insight into a solution?

Thanks.

You would need to cd into grpc/third_party/protobuf, then do a "git clean -f -d -x". Go back to the grpc/ directory and to make again.
