Spirit has been tested to compile and run properly on various compilers:

1. g++ 2.95.3
2. g++ 3.1
3. g++ 3.2
4. Borland 5.5.1
5. Borland 5.6.1
6. Intel 5.0
7. Intel 6.0
8. Intel 7.0Visual Age C++ 5.02
9. Comeau 4.24.5
10. Metrowerks CodeWarrior 7.2
11. Metrowerks CodeWarrior 8.3
12. MSVC 6 SP5
13. MSVC 7
14. MSVC 7.1

Spirit is 100% ANSI/ISO C++ conformant. Unfortunately, some compilers do not support all the features of Spirit primarily due to bugs and inadequate conformance to the standard. Finding workarounds for these non-conformance problems is a high priority but it takes time and a lot of effort.

- MSVC 6 and 7 does not support partial template specialization (PTS). Some features that rely on PTS therefore does not compile on MSVC 6 and 7. This include Closures, Lambda expressions as semantic actions (Phoenix and BLL), and the Trees (Abtract Syntax Trees and Parse Trees). Hopefully, these features will be ported to support MSVC 6 and 7. However, The much anticipated MSVC 7.1 do support PTS and was tested to fully compile Spirit.
- The list parsers and comment parsers do not compile on MSVC6 yet. Use the `%` operator instead.
- The multi_pass does not compile on MSVC6, MSVC 7 and Metrowerks 7.2 yet.
- Comeau has a problem with the `file_iterator`. The problem is not related to conformance to the standard at all. Comeau, an EDG based compiler, is one of the most conformant compiler in existence. The problem is the `file_iterator`'s use of posix API calls.
- The regular expression parsers does not compile on both MSVC6 and 7, Intel 5.0 and Comeau 4.24.5
- Metrowerks CodeWarrior 7.2 does not compile all the meta-parsers and features that rely on it such as the dynamic parsers. This is because CodeWarrior 7.2 gives wrong results on code that uses the `sizeof` trick such as the implementation of `boost::is_base_and_derived` and `boost::is_convertible`.
