----

==What==

* Select proper IDE
* Replace MSDEV build scripts with new ones
* Attach Subversion plugin
* Create default workspace settings
* Migrate GUI project

==How==

* After close look Eclipse has been rejected because it is much more Java, but has weaknesses for C++ - too slow, debug is unavailable
* Codelite is chosen as next target IDE for migration

findings:
* Except Codelite itself, MinGW required and OpenSSH (used for Clean)
* -static required to avoid MinGW runtime dlls to be used
* link order should used accurately - e.g. aiconsole requires first linking to aiapi, then to ws2_32

changes in the code:
* "for( int x" - x now is inside for block, not visible outside
* when passing class function as argument from class method, g++ requires using construction:
<pre>
"&<class>::<function>"
</pre>
* "thread" keyword is unsupported by g++, changed to Tls function calls
* g++ has found several errors in unused template functions
* now commented C++ handling of SEH exceptions - TBD
* static string data require const keyword in g++
* more strict checking is for pointer conversions in C++ under g++ - unable to convert implicitly `void'''` to `char'''`
* varargs is no more supported in g++ - replaced with stdarg version (in fact varargs existed before because of UNIX compatibility issues)
* varargs now puts char/short as int to stack
* generic headers have been updated - checked in new generic version to aiengine
* not resolved question - moment type is now stale - its calendar limit is overdue
* found non-english constants for calendar terms - replaced with english ones
* unicode constant is not `ushort*` - forced conversions, needs investigations - TBD
<pre>
L"<string>"
</pre>
* for g++ HINSTANCE is not `void*`
* min, max macros are defined in system headers - added #ifndef blocks
* `__int64` is replaced with long long int
* C-level MSDEV-specific `__try/__catch` was replaced with try/catch - don't know about impact on functionality

change, done by the way - all projects now conform to common structure rules - see related section at [[DevelopmentEnvironment]]
