Platform

You should use a platform configuration that match your target.

By default Cppcheck uses native platform configuration that works well if your code is compiled and executed locally.

Cppcheck has builtin configurations for Unix and Windows targets. You can easily use these with the --platform command line flag.

You can also create your own custom platform configuration in a XML file. Here is an example:

<?xml version="1"?>
<platform>
  <char_bit>8</char_bit>
  <default-sign>signed</default-sign>
  <sizeof>
    <short>2</short>
    <int>4</int>
    <long>4</long>
    <long-long>8</long-long>
    <float>4</float>
    <double>8</double>
    <long-double>12</long-double>
    <pointer>4</pointer>
    <size_t>4</size_t>
    <wchar_t>2</wchar_t>
  </sizeof>
</platform>
