I am trying to automatically generate the extension of my DLLs to get FileName.$(Platform).DLL. Supposedly I can use {$E ext} to set the extension to FileName.ext, and I want FileName.ext.dll

The problem is if I use {$E ext} I get FileName.ext as expected, but when I use {$E ext.dll} I get FileName.ext.ext.dll. My compiler directives in the *.dpr file reads:

{$IFDEF MSWINDOWS}
  {$IFDEF WIN64}
    {$E x64.dll}
  {$ELSE}
    {$E x86.dll}
  {$ENDIF}
{$ENDIF}

This creates FileName.x64.x64.dll or FileName.x86.x86.dll. Am I missing something? Is there a way to avoid the double "ext" on XE7?

I don't think it's designed to work that way. Could you do the name change in an AfterBuild handler instead? – Ken White Apr 24 '20 at 03:09
I am not familiar with AfterBuild handlers. I will lookup and read (any pointers would be appreciated) – Nani Apr 24 '20 at 03:14
Project->Options->Build Events. – Ken White Apr 24 '20 at 03:16
I could get "Win32" instead of "x86" if the following works: But it exits with Error Code 1 in PostBuild: *ren $(OutputDir)$(OutputFileName) $(OutputDir)$(OutputName).$(Platform)$(OutputExt)* – Nani Apr 24 '20 at 05:13
The directive is for setting the extension but you are trying to modify the filename. Do that with a post build event or similar. – David Heffernan Apr 24 '20 at 06:53

Just use `$LIBSUFFIX`, You should not try and control the file extension in the source – Dave Nottage Apr 24 '20 at 07:40
$LIBSUFFIX seems to work only with *.bpl not *.dll. – Nani Apr 24 '20 at 14:07
