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?
