Lexilla.dll does not work with win32

[Carsten]

I have compiled scite without STATIC_BUILD to use lexilla.dll with win32. The compilation works fine but I doesn't have syntax highlighting.

The problem are the exported function names from lexilla.dll. With win64 GetProcAddress find a valid address. With win32 it doesn't.

With win64 one exported function name is GetLexerCount, with win32 it is _GetLexerCount@0.

I have changed the defines in lexilla.h to 

#define LEXILLA_GETLEXERCOUNT "_GetLexerCount@0"

#define LEXILLA_GETLEXERNAME "_GetLexerName@12"

#define LEXILLA_GETLEXERFACTORY "_GetLexerFactory@4"

#define LEXILLA_CREATELEXER "_CreateLexer@4"

#define LEXILLA_LEXERNAMEFROMID "_LexerNameFromID@4"

#define LEXILLA_GETLIBRARYPROPERTYNAMES "_GetLibraryPropertyNames@0"

#define LEXILLA_SETLIBRARYPROPERTY "_SetLibraryProperty@8"

#define LEXILLA_GETNAMESPACE "_GetNameSpace@0"

Then it works with win32 too. I think this is an error.

For gcc, that should have been fixed with
https://github.com/ScintillaOrg/lexilla/commit/9e60005b9044f2f09724c289f80a4458898bc928#diff-bc80c8ec09d04e5b45a0c916a16106d1201d7e4442e65f6b14482487ae00e00b

If you are using MSYS2 then switch to MinGW-64 from a CMD prompt.

It shouldn’t occur with Visual C++ as it uses Lexilla.def to set the names.

I built Scite with Visual C++ in MSVC 2019.

In lexilla.mak there is a linker option -DEF:Lexilla.def which is missing in Lexilla.vcxproj.

I added the link option 

     <ModuleDefinitionFile>lexilla.def</ModuleDefinitionFile>

to Lexilla.vcxproj then it works.

I wonder why generation for win64 work although the link option is missing too.

There is another problem: The entry LexerNameFromID in lexilla.def is missed.

EXPORTS

GetLexerCount

GetLexerName

GetLexerFactory

CreateLexer

GetLibraryPropertyNames

SetLibraryProperty

LexerNameFromID   <---

GetNameSpace

   On 64-bit Windows a single calling convention is used for both cdecl and stdcall so there is no need to decorate the stdcall name. On 32-bit Windows, these calling conventions are different.

There is another problem: The entry LexerNameFromID in lexilla.def is missed.
