Question

我按照维基https://wiki.gnuradio.org/index.php/Guided_Tutorial_GNU_Radio_in_Python#3.2.1._Using_gr_modtool生成了OOT模块并进行了安装。此步骤没有问题。但是，我在运行gnuradio-companion时遇到问题。我收到以下错误。

pradmc$ gnuradio-companion

XML parser: Found 1 erroneous XML file while loading the block tree (see "Help/Parser errors" for details)

它说有一个错误的XML文件。我确认这是因为我的模块。没有我的模块，我看不到错误。我模块的xml非常简单，只有一个源和一个接收器。

<?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>

我怎么知道什么是解析器错误？我不确定上述XML有什么问题。

关于， Pradeep M C
