Undefined symbol: __endthreadex on FPC 3.1.1

Hi,
I am using the Lazarus version created with fpcup (Lazarus 1.5 32b on Win 7 64b).
I have downloaded the latest nightly build and the additional files based on the links in the documentation (http://synopse.info/files/html/Synopse% … l#TITL_113).

I am getting Undefined symbol: __endthreadex both when I try to run compilFPC.bat or when compiling 02 - Embedded SQLite3 ORM.
I did not get this error when compiling 01 - In Memory ORM.
Please advise what I am missing.

Re: Undefined symbol: __endthreadex on FPC 3.1.1

Please try with the updated .o files from http://synopse.info/files/sqlite3fpc.7z

Note that we started supporting Win64 target, and include some sqlite3 static linking.
Not fully working yet, but we seem in a good path!

Re: Undefined symbol: __endthreadex on FPC 3.1.1

There are a few typos in SynSQLite3Static.pas ... sorry about that !

These two
-  {$ifdef FPC}{$ifdef CPU64}alias : '__imp__beginthreadex'{$else}alias : '__imp___beginthreadex'{$endif};{$endif}
+  {$ifdef FPC}{$ifdef CPU64}alias : '__imp__beginthreadex'{$else}alias : '__beginthreadex'{$endif};{$endif}

-  {$ifdef FPC}{$ifdef CPU64}alias : '__imp__endthreadex'{$else}alias : '__imp___endthreadex'{$endif};{$endif}
+  {$ifdef FPC}{$ifdef CPU64}alias : '__imp__endthreadex'{$else}alias : '__endthreadex'{$endif};{$endif}

and maybe:
-  {$ifdef FPC}{$ifdef CPU64}alias : 'localtime'{$else}alias : '__localtime32'{$endif};{$endif}
+  {$ifdef FPC}{$ifdef CPU64}alias : 'localtime'{$else}alias : '_localtime'{$endif};{$endif}

Re: Undefined symbol: __endthreadex on FPC 3.1.1

@AOG It works on my side, with the .o supplied in the latest http://synopse.info/files/sqlite3fpc.7z
So it should not be necessary to change anything in SynSQLite3Static.pas.

AFAIR the exports of your mingw compiled .o are not the same.
I used the latest mingw 5.2 version (see the updated .bat files in the trunk).

Hi,
I am not having the message anymore with the new files.
I will go for the blog creation next.

Thank you very much,
Tudor

You're right Ab !
Thanks for providing the correct binaries !!
They work without changes on my side also.
