Hi all,

Great job !!!

Thanks.

Well done and thanks for your effort

Good work

We need a Components section in the main site of Lazarus, collect all the link to external components and tools.

We need a Components section in the main site of Lazarus, collect all the link to external components and tools.

We already have: http://wiki.lazarus.freepascal.org/Components_and_Code_examples

In the Lazarus Day someone also mentioned that we need this page, but the page that I linked is the first match for "lazarus components" without quotes in google.

Yes, i think it is more useful to put that links in the main site of Lazarus, like Download and FAQ links.

Hi, using the steps below, I managed to compile the latest FPC snapshot source - i didn't use SVN, just download the zip file. However, after updating the paths in Environment Options, i tried to rebuild Lazarus v0.9.31 using the FPC binaries i just compiled, but got the following errors. I tried researching on that error, but no luck. Grateful for any pointer. Thanks.

Steps used to complile FPC snapshot:

1. Copy the files inside \fpc to C:\FPC\. The subfolders packages, rtl, etc should also be copied.

2. Copy \bin\i386-win32\ from already installed FPC to c:\FPC\.

3. Add path to \bin\i386-win32\ to system variable path e.g. path = C:\FPC\bin\i386-win32
This setting can be found under control panel -> System -> Advanced System Settings -> Advanced -? Environment Variables -> System Variables. Make sure this path is before borland's make path. Restart PC.

4. CD to c:\FPC, issue:- make all OPT='-va' > c:\buildlog.log.

5. Then issue:- make install INSTALL_PREFIX=c:\FPC\compiled\

6. Copy everything in C:\FPC\compiled\ to
D:\Data\Lazarus-0.9.31-fpc-2.4.3-win32\fpc\2.5 (or 2.x.x, whichever fpc version you are installing).

7. Copy C:\FPC\rtl\ and C:\FPC\packages\ to
D:\Data\Lazarus-0.9.31-fpc-2.4.3-win32\fpc\2.5\source (or 2.x.x, whichever fpc version you are installing).

8. Copy fpc.cfg from \fpc\bin\i386-win32 of your old Lazarus FPC folder (e.g. D:\Data\Lazarus-0.9.31-fpc-2.4.3-win32\fpc\2.4.4\bin\i386-win32) to D:\Data\Lazarus-0.9.31-fpc-2.4.3-win32\fpc\2.5\bin\i386-win32 (or 2.x.x, whichever fpc version you are installing).

Modify the paths in fpc.cfg to reflect the new version fpc path. You can use mass search and replacement of fpc\2.4.4/ to fpc\2.5/ (if upgrading from 2.4.4 to 2.5).

9. Run Lazarus, go to Environment -> Options, update all FPC path to v2.5 Go to Tools -> Configure "Build Lazarus", select profile "Build All" - you may need to remote "Examples".
Check "Clean all" and "With packages". Proceed with "Build".

It compiled for me yesterday afternoon, but there were runtime errors in generated code. I'll try again presently in case somebody was working on it when I SVNed Lazarus.

Modify the paths in fpc.cfg to reflect the new version fpc path. You can use mass search and replacement of fpc\2.4.4/ to fpc\2.5/ (if upgrading from 2.4.4 to 2.5).

I wonder why fpc.cfg hasn't been correctly set up with an $fpcversion macro, but instead has a hardcoded version number? This is something I noticed last week when compiling 2.4.4 on a system that already had 2.4.2, but I very rarely use Windows as a development platform.

One thing I do notice as a general point is that 0.9.3x appears to be sensitive to version-specicivities in the files in the .lazarus directory. If experiencing runtime problems delete it and start over.

You'll need lazarus svn > 30332. FPC has added tkHelper in TTypeKind enumeration (typeinfo.pp).

You'll need lazarus svn > 30332. FPC has added tkHelper in TTypeKind enumeration (typeinfo.pp).

Is there documentation on tkHelper? What exactly does it describe? Just curious.

Yes, you are right. To explain this a bit:

In Delphi "helper" classes (and records) are basically classes that magically derive from a TClassHelperBase (or so) class which in turn derives from TInterfacedObject.
In FPC I have decided to implement them as a true first class type and thus I decided that they deserve their own RTTI type as well. The type data of them contains the class or record helper they derive from (if any) and the class or record they extend.

For an example see this section on the wiki page linked by Ludo: http://wiki.lazarus.freepascal.org/Helper_types#Differences_between_Delphi_and_FPC

Sven

Thank Ludo and Sven for your answers. If "helper types" or "helper classes" are what I think they are, then it would be a very welcome (and long sought after) addition to FPC. I'll read further on the wiki page to get more detail.

You are welcome to test them. I've have tried to make them as good tested as possible (the tests are in $fpcdir/tests/test and are named thlp*.pp, tchlp*.pp and trhlp*.pp), but there might still be errors and oversights (only some weeks ago Michael brought some bugs to my attention when documenting the new feature).

Also they are currently implemented as Delphi compatible as reasonably possible, but I'm nevertheless open for improvements if I can somehow allow a Delphi compatible behavior as well (the RTTI related stuff is one of the exceptions ^^ ).

Sven
