error: 'PACKAGE_VERSION' was not declared in this scope

Hi,

I have created Boilerplate from GStreamer Plugin Templates. Meson build is successful and gst-inspect command recognizes this new plugin.

I need c++ code features so I renamed the generated files from .c to .cpp of template. Not sure if this is the right way to do and I am not aware if boilerplate can generate .cpp files too. I have modified meson.build as below to support cpp project('gst-template', 'cpp', version : '1.16.2.1', license : 'LGPL') cc = meson.get_compiler('cpp')

This landed me into trouble. gstplugin.c -> gstplugin.cpp I see below errors error: 'PACKAGE_VERSION' was not declared in this scope error: 'GST_LICENSE' was not declared in this scope; did you mean 'GST_TAG_LICENSE'? error: 'GST_PACKAGE_NAME' was not declared in this scope; did you mean 'GST_PAD_NAME'? error: 'GST_PACKAGE_ORIGIN' was not declared in this scope

To get past this issue, I tried hard-coding with appropriate strings for PACKAGE_VERSION, GST_LICENSE, GST_PACKAGE_NAME, GST_PACKAGE_ORIGIN, but this generates new error below

error: 'GST_PLUGIN_DEFINE' does not name a type

I am right now stuck at this point. Any suggestion on what could be the problem? I have attached source code zip file for reference. plugin-temp.zip

Thank you in advance !
