Dear FPC-All!

If there is possibility publishing .SO export symbol outside the main file exports section?

I'm playing with http://bugs.freepascal.org/view.php?id=17805

I can include into .SO project the following unit. It compiles but does not export symbol.

unit reshdr;
{$mode objfpc}
interface
var rh : pointer; external name 'FPC_RESLOCATION';
implementation
exports
   rh;
end.

but FPC_RESLOCATION gets exported only when mentioned in main module export section.

regards,
Anton

I can include into .SO project the following unit. It compiles but does not export symbol. Only export from module containing the word 'library' works.

unit reshdr;
{$mode objfpc}
interface
var rh : pointer; external name 'FPC_RESLOCATION';
implementation
exports
   rh;
end.

but FPC_RESLOCATION gets exported only when mentioned in main module export section.

Yes, that's correct: http://bugs.freepascal.org/view.php?id=16070

Btw -
exports directive in implementation section of unit works but only under win32.
Compiling the code under Linux with PIC does not export anything.

library a;
{$R *.res}
uses unita;
end.
unit unita;
interface
implementation
var pa:pointer;//external name 'FPC_RESLOCATION';
exports pa;
end.

$fpc -Cg a.pas

Should I report this as separate bug?
