Cannot compile last timeline version

After a long time I have try to upgrade my Synopse with last timeline version (2020-05-14 16:06:21).

On Delphi 10.3 I get these errors:

Re: Cannot compile last timeline version

The only supported targets for this brunch is FPC 3.2.0 x64 Linux (cross compile to Windows). Sorry, I don’t have the resources to support anything else

Re: Cannot compile last timeline version

Is there any news on this ? As @array81 reported, latest mORMot and SyNode are incompatible with each other when Delphi is used.

Re: Cannot compile last timeline version

The following regex could be helpful to alleviate the burden to support Delphi compatibility of SpiderMonkey.pas

(?gs)type\s([_A-Za-z]+)\s*=\s*(function|procedure)(.*?cdecl;)\s*var(\s[_A-Za-z]+):\s*([_A-Za-z]+)\s(external.*?;)

Re: Cannot compile last timeline version

I can resolve an error "Class methods in record types must be static" - it's not a problem.

Problem is about E1030 Invalid compiler directive: 'external'

SpiderMonkey itself is a C++, so we need to export a C++ function as a cdecl.
To avoid unnecessary function call we export a variable what contains pointer to a C++ function from our wrapper - see synsm.h line 10 for example as such:

extern "C" {
  JS_PUBLIC_API(bool) (*SM_Initialize)(void) = &JS_Init;

SM_Initialize is a pointer to a function.

And when import it in the SpiderMonkey.pas using

type TJS_Initialize = function : Boolean; cdecl;
var JS_Init: TJS_Initialize external SpiderMonkeyLib name 'SM_Initialize';

I don't know how to do such in Delphi.

Re: Cannot compile last timeline version

If the following two code blocks are equivalent to each other, the regex posted above could be used to automatically transform the hundreds of declarations in SpiderMonkey.pas big_smile

current 

type TJS_Initialize = function : Boolean; cdecl;
var JS_Init: TJS_Initialize external SpiderMonkeyLib name 'SM_Initialize';

Delphi compatible

function SM_Initialize: Boolean; cdecl; external SpiderMonkeyLib name 'SM_Initialize';
type TJS_Initialize = function : Boolean; cdecl;
var JS_Init: TJS_Initialize = SM_Initialize; // external SpiderMonkeyLib name 'SM_Initialize';

Re: Cannot compile last timeline version

@ComingNine - `SM_Initialize` exported by SpiderMonkeyLib is a pointer to function, not a function. So 

function SM_Initialize: Boolean; cdecl; external SpiderMonkeyLib name 'SM_Initialize';

not works (at last in FPC I got AV).
Did you verify your code in Delphi? It's work?

Re: Cannot compile last timeline version

Thank you for your efforts ! IIRC, to realize a pointer to external function in Delphi (and FPC as well), one does not use external keyword but SafeLoadLibrary followed by GetProcAddress. I have to try and return.
