[edit] Introduction

There are some efforts to build the (Free)CLX with FPC, here is a short explanation how to build it. For Win32 the Delphi 7 CLX is used while on linux the Kylix 3 CLX is used.

Further, FPC from svn (2.3.1 or 2.2.1) is used.

[edit] Status

Current status is that all units except the database related units build.

That's 39 of 44 units.

Today (02.07.2007) I get perfectly compiled Qxxx units and test application (written with Kylix). fpc-2.0.4 (i386 rpm from lazarus snapshots build 20070701), fpc-2.1.5 (build 20070702) cannot do the job.

[edit] Howto

• Build and install FPC from SVN sources: How_to_start
• copy the clx sources to a newly created directory as well as the
  • Win32 only: CommDlg.pas from Source/Rtl/Win/
  • Win32 only: CommCtrl.pas from Source/Rtl/Win/
  • Win32 only: ShlObj.pas from Source/Rtl/Win/
  • Win32 only: RegStr.pas from Source/Rtl/Win/
  • Win32 only: WinInet.pas from Source/Rtl/Win/
  • Win32 only: UrlMon.pas from Source/Rtl/Win/
  • Win32 only: WinSpool.pas from Source/Rtl/Win/
  • Linux only: XLib.pas from source/rtl/linux/
  • MaskUtils.pas from Source/Rtl/Common/
  • Contnrs.pas from Source/Rtl/Common/
  • HelpIntfs.pas from Sources/Common/
  • IniFiles.pas from Source/Rtl/Common/
  • Registry.pas from Source/Rtl/Common/
  • Linux only: QFileCtrls.res from Lib/ and rename it to qfilectrls.res
  • Linux only: rename DirSel.xfm to dirsel.xfm
  • QButtons.res from Lib/
  • QDialogs.res from Lib/
  • QDBCtrls.res from Lib/
  • QCheckLst.res from Lib/
  • QFileCtrls.res from Lib/
  • Linux only: rename QFileDialog.res to qfiledialog.res
  • Linux only: rename QDialogs.res to qdialogs.res
  • Linux only: rename QDBPWDlg.xfm to qdbpwdlg.xfm
  • Linux only: rename QDBLogDlg.xfm to qdblogdlg.xfm
• remove all references to *.xfm files, fpc can't handled them yet (fix this!!)
• D7 CLX only: remove usage of sysinit namespace in qdialogs.pas; system can be used instead
• replace all RTLConsts with RTLConst (fix this!!) (should be fixed after 1.9.8)
• D7 CLX only: fix ShlObj.pas: the lines 3554 to 3557 miss a semicolon at the end; FPC won't emulate bugs in the Delphi parser
• Linux ONLY : Add dynlibs unit after implementation (LoadLibrary & FreeLibrary needs it). Compiling with the -Sk switch should be enough
• Remove sysutils from uses clause of implementation section of QStyle.pas
• 2.2.1 only:
  • Change {$R *.xfm} to {$R *.res} in QFileDialog.pas
  • Convert QFileDialog.xfm to resource. It can be done with fpcres utility from a 2.3.1 snapshot: fpcres -of res QFileDialog.xfm
• create a dummy unit to build the clx:
  

unit buildclx;
  interface
   uses
     BindHelp,   QDBActns,   QFileCtrls,
     QActnList,  QFileDialog,  QSearch,
     QButtons,   QForms,     QStdActns,
     QCheckLst,  QGraphics,  QStdCtrls,
     QClipbrd,   QGrids,     QStyle,
     QComCtrls,  QImgList,   QTypes,
     QConsts,    QDialogs,   QMask,
     QControls,  QExtCtrls,  QMenus,
     Qt,         QPrinters;
  implementation
end.

• build the CLX with

 fpc -Sd buildclx -Rintel 

on windows and

 fpc -Sdk buildclx -Rintel 

on linux.

[edit] Building the DB units

Building of the DB units isn't possible yet, however, at least the following steps must be done:

• copy the following files into the directory where you put the clx source:
  • DB.pas from Sources/Vcl
  • SqlTimSt.pas from Sources/Vcl
  • DBConsts.pas from Sources/Vcl

[edit] Todo

As you might guess, there is also stuff to do:

• The ClassGrouping functions are only dummies in FPC (StartClassGroup et al.)
