I followed the wiki https://wiki.gnuradio.org/index.php/Guided_Tutorial_GNU_Radio_in_Python#3.2.1._Using_gr_modtool to generate a OOT module and install it. No issues with this step. However, I am facing an issue while running gnuradio-companion. I get the following errors.
pradmc$ gnuradio-companion

XML parser: Found 1 erroneous XML file while loading the block tree (see "Help/Parser errors" for details)
It says there is one erroneous XML file. I confirmed it is because of my module. Without my module i don't see the error. My module's xml is a very simple with one source and one sink.
<?xml version="1.0"?>
<block>
<name>constant_gen_ii</name>
<key>constant_gen_ii_constant_gen_ii</key>
<category>Misc</category>
<import>import constant_gen_ii</import>
<make>constant_gen_ii.constant_gen_ii($max)</make>
<!-- Make one 'param' node for every Parameter you want settable from the GUI.
Sub-nodes:
* name
* key (makes the value accessible as $keyname, e.g. in the make node)
* type -->
<param>
<name>max</name>
<key>max</key>
<type>int</type>
</param>
<--- Make one 'sink' node per input. Sub-nodes:
* name (an identifier for the GUI)
* type
* vlen
* optional (set to 1 for optional inputs) -->
<sink>
<name>in</name>
<type>int</type>
</sink>
<!-- Make one 'source' node per output. Sub-nodes:
* name (an identifier for the GUI)
* type
* vlen
* optional (set to 1 for optional inputs) -->
<source>
<name>out</name>
<type>int</type>
</source>
</block>
How do I know what were the parser errors? I am not sure what is wrong with the above XML.
