If `BOOST_TYPE_INDEX_FUNCTION_SIGNATURE` macro is not defined or
`BOOST_TYPE_INDEX_CTTI_BEGIN_SKIP` and `BOOST_TYPE_INDEX_CTTI_END_SKIP`
are defined to zero then you are using a compiler that was not tested with this library.
In that case if you wish to use this library with RTTI off, you must correctly define
`BOOST_TYPE_INDEX_FUNCTION_SIGNATURE`, `BOOST_TYPE_INDEX_CTTI_BEGIN_SKIP` and
`BOOST_TYPE_INDEX_CTTI_END_SKIP` macros:
# define `BOOST_TYPE_INDEX_FUNCTION_SIGNATURE` to a compiler specific macro, that outputs the *whole*
function signature, including template parameters
# get the output of `boost::typeindex::ctti_type_index::type_id<int>().name()`
# set `BOOST_TYPE_INDEX_CTTI_BEGIN_SKIP` equal to characters count before last occurrence of `int` in output
# set `BOOST_TYPE_INDEX_CTTI_END_SKIP` equal to characters count after last occurrence of `int` in output
# check that `boost::typeindex::ctti_type_index::type_id<int>().name_demangled()` returns "int"
# (optional, but highly recomended) [@http://www.boost.org/support/bugs.html create ticket] with
feature request to add your compiler to supported compilers list. Include
`BOOST_TYPE_INDEX_FUNCTION_SIGNATURE`, `BOOST_TYPE_INDEX_CTTI_BEGIN_SKIP` and
`BOOST_TYPE_INDEX_CTTI_END_SKIP` values.
Consider the following example:
With `BOOST_TYPE_INDEX_CTTI_BEGIN_SKIP` and `BOOST_TYPE_INDEX_CTTI_END_SKIP` set to `0`,
`boost::typeindex::ctti_type_index::type_id<int>().raw_name()` returns
"const char *__cdecl boost::detail::ctti<int>::n(void)". Then you shall set
`BOOST_TYPE_INDEX_CTTI_BEGIN_SKIP` to `sizeof("const char *__cdecl boost::detail::ctti<") - 1`
and `BOOST_TYPE_INDEX_CTTI_END_SKIP` to `sizeof(">::n(void)") - 1`.

[section Define the BOOST_TYPE_INDEX_FUNCTION_SIGNATURE macro]
If you get the following error during compilation
``
TypeIndex library could not detect your compiler.
Please make the BOOST_TYPE_INDEX_FUNCTION_SIGNATURE macro use
correct compiler macro for getting the whole function name.
Define BOOST_TYPE_INDEX_CTTI_USER_DEFINED_PARSING to correct value after that.

[section Fixing pretty_name() output]
If the output of `boost::typeindex::ctti_type_index::type_id<int>().name()`
* returns not just `int` but also a lot of text around the `int`
* or does not return type at all
then you are usng a compiler that was not tested with this library and you need to setup the
[macroref BOOST_TYPE_INDEX_CTTI_USER_DEFINED_PARSING] macro using [macroref BOOST_TYPE_INDEX_REGISTER_CTTI_PARSING_PARAMS].
Here is a short instruction:
# get the output of `boost::typeindex::ctti_type_index::type_id<int>().name()`
# define [macroref BOOST_TYPE_INDEX_CTTI_USER_DEFINED_PARSING] to
`BOOST_TYPE_INDEX_REGISTER_CTTI_PARSING_PARAMS(skip_at_begin, skip_at_end, false, "")`, where
* `skip_at_begin` is equal to characters count before the first occurrence of `int` in output
* `skip_at_end` is equal to characters count after last occurrence of `int` in output
# check that `boost::typeindex::ctti_type_index::type_id<int>().name_demangled()` returns "int"
# if it does not return `int`, then define BOOST_TYPE_INDEX_CTTI_USER_DEFINED_PARSING to
`BOOST_TYPE_INDEX_REGISTER_CTTI_PARSING_PARAMS(skip_at_begin, skip_at_end, true, "T = ")`, where
* `skip_at_begin` is equal to `skip_at_begin` at step 2
* `skip_at_end` is equal to `skip_at_end` at step 2
* `"T = "` is equal to characters that are right before the `int` in output

parameters provided to `BOOST_TYPE_INDEX_REGISTER_CTTI_PARSING_PARAMS` macro.
Consider the following example:
`boost::typeindex::ctti_type_index::type_id<int>().raw_name()` returns
"const char *__cdecl boost::detail::ctti<int>::n(void)". Then you shall set
`skip_at_begin` to `sizeof("const char *__cdecl boost::detail::ctti<") - 1`
and `skip_at_end` to `sizeof(">::n(void)") - 1`.

Another example:
