What is the best way to migrating from Laz 0.9.30 (fixes_0_9_30) to Laz 0.9.31 (trunk)?

My environment now is:
- WinXP
- FPC 2.4.5 (fixes_2_5)
- Laz 0.9.30 (fixes_0_9_30)
- Paths:
c:\freepascal\compiler\2.4.5 (FPC)
c:\freepascal\ide\laz\0.9.30 (that works)
c:\freepascal\ide\laz\0.9.30-config (--pcp=...
environmentoptions.xml, fpcdefines.xml, compileroptions.xml, etc) c:\freepascal\ide\laz\0.9.31 (trunk... the new Laz) c:\freepascal\ide\laz\0.9.31-config (a copy from 0.9.30-config... but I replaced all 0.9.30 texts to 0.9.31 in all files)

I want to compile the Lazarus on trunk, but I want migrate my packages too.

So,
1. I got the sources
2. compiled the first time... everything ok.
3. close the IDE, copy 0.9.30-config to 0.9.31-config and replaced all 0.9.30 texts to 0.9.31 in all files
4. open IDE without errors.
5. build up + clean all using the main menu
6. IDE compile all files, creates the lazarus.new.exe and restart.
7. ERROR(?) I see the image in attachment.

What happend?
How I can migrate?

Thanks,
Marcos Douglas

I mean: - FPC 2.4.5 (fixes_2_4)
I forgot the file... in attachment now.

Well, well, well... I don't know what this mean the error before, but I managed:

1. restored lazarus.old.exe to lazarus.exe
2. start IDE (I see just the default pallete)
3. click in 'Package'>'Install/Unistall packages...'
4. I see my packages in the "Install list"...
5. I choose any package the the "Do not Install" (the rebuild button was enabled)
6. click in "Save and rebuild IDE"
7. my packages were installed!

=)

Is the best way to do this?

Marcos Douglas

NOT, the error continues...
If I use the menu Build, the error that I talked in first mail continues.

Anybody have an idea?

Marcos Douglas

Try to delete *ALL* *.ppu and *.o file in the entire lazarus directory then rebuild.

Maybe some path was changed, and now the file exists in both locations. clean will only clean the one that will be rebuild

While the first bit may help, sorry, I mixed up to mails while reading, and answered to the mixture I read (applied another erro msg to your mail...)....

I have been continually updating from SVN. I never needed to go into the package menu.

When you migrate, there may be a point where you have to build from the commandline with "make" => or you get a pre-build lazarus exe from a snapshot.

Then with that l;azarus.exe you can use the Menu Tools/Build dialog. And that should rebuild it with the list of configured packages.

Martin

I did this and now I can not compile...
Error: \ide\laz\0.9.31\packager\registration\fcllaz.pas(1,1) Fatal: Can't find unit system used by fcllaz

But how I installs (migrate) my packages old 0.9.30 to 0.9.31? The way I said before is right?

Marcos Douglas

Now, I'm downloading a new Lazarus' source, from trunk, to start again. But my question is: how I can migrates my packages, components and configurations from my old Lazarus to new?

Marcos Douglas

system is rtl.

Are you sure you are using the same FPC version?
Or if you changed it, your path, and fpc.cfg are correct.

That sounds a lot like you fpc is having the wrong path to the system.ppu (trying to use a system.ppu from an older fpc)

Usually your list of packages is in your config dir (afaik staticpackages.inc)

If you rebuild lazarus from tool menu, it should include them all. If it says, it can't find one, just open the .lpk file , and it will remember where it is.

Configuration is all stored in

Vista:
C:\Users\yourname\AppData\Local\lazarus

XP c:\Document and Settings\somewhere\lazarus

linux
/home/yourname/.lazarus

So it should all be kept.
you can backup it if you whish.

If you have paralell installations, you must have one folder for each install (or it will get messy over time...)
start lazarus with --primary-config-path=\whatever\directory\

One more, if you keep your old install (see primary-config-path / other mail), I su8ggest to temporarly rename the folder of the old installation.

so when you recompile the new installation, if anything should still point to the old path, you will get an error indicating this => rather than some weird error

There has been made a change in TCustomForm.Create constructor. It raises now an exception if the descendant has no resources. One of your packages needs to be adapted. More info here (look in the notes): http://bugs.freepascal.org/view.php?id=19389

Ludo

Yes. I have one fpc.cfg for each fpc.exe in \bin\i386-win32 to not have problems with PATH.

That sounds a lot like you fpc is having the wrong path to the system.ppu (trying to use a system.ppu from an older fpc)

The last problem happend after that I deleted all *.ppu *.o

Was I did and worked (well, I thought). But if I recompile using the menu Build, happens the error that I said in first mail of this thread.

If it says, it can't find one, just open the .lpk file , and it will remember where it is.

If I have to open each .lpk then I do not need this all... just compile a new Lazarus and install each package.

Marcos Douglas

I use -pcp, always. Was I said in the first mail: I have one directory (configuration) for each Lazarus (for \laz\0.9.30 so \laz\0.9.30-config).

Marcos Douglas

I tested this... but is not.

Marcos Douglas

Hmm... but which package? Would be better if the error message said what class is "wrong". I use the packages default of Lazarus and Zeos, just this.

Marcos Douglas

I am not sure it is a package, or that it is the packages fault.

Look exactly at the error. IT is a "TForm1" for which the resources are missing.

If a packages tries to create a resourceless form, then it would be just a "TForm" (the package would call TForm.Create)

Now if it is a package (wich as unlikely as it sounds to me, has a TForm1, rather than aproper named form), then it's a problem with resources. e.g some resource, did not get compiled, some .lfr not created or included, or some $I *.LFM missing or not working....

Maybe it is failing to open your current project. Try opening Lazarus without project (remove from your config folder)

Hmm... but which package? Would be better if the error message said what class is "wrong". I use the packages default of Lazarus and Zeos, just this.

I'm not using zeos on lazarus. I can't tell.
The error message complains about a form called TForm1. That'll make searching easier.

Ludo

The IDE try to open a new project, not the my last project. I compiled the IDE with FPC 2.4.5 (fixes_2_4). Would be this the problem? The Lazarus trunk only compiles with FPC trunk?

Marcos Douglas

The Lazarus try to open a new project and, because that, the name is TForm1, I think.

Marcos Douglas

I don't thing thats the problem. I am using a 2.5.1 version that is a few month old. very similar to 2.4.4 or.5

Compile you laz with debug -g -g- info, and either with -WC (console) or run with --debug-log=file

then you may get a stacktrace.

or run lazarus.new.exe, in the debugger, in lazarus itself.

Try doing a lazarus build without packages from the command line "make clean all". This will make it clear where the problem is, the packages or lazarus.

Ludo

I got the fixes_2_6 to do tests too.

Compile you laz with debug -g -g- info, and either with -WC (console) or run with --debug-log=file

Sorry to ask but these parameters are to the 'make' tool?

then you may get a stacktrace. or run lazarus.new.exe, in the debugger, in lazarus itself.

I never did this... can you explain, please?

Marcos Douglas

That works, sure -- was I did and explained at the first mail on this thread. But the question persists: how migrate the packages to a new version? If I compile a clean source and install each package separate, ok it will works... but I can't do this everytime that a version is launched, right?

How do you works with that?

AFAIK:
make <target> OPT="-g -gl -WC"

I usually compile from within the IDE (tools menu). Anjd that for me always also recompiled the packages.

That is assuming the packages are compatible with the new version. If a package does not work any longer then it can't be migrated, until the package is updated too (if available)

--debug-log= is given to lazarus.exe when you start lazarus (use a windows shortcut, edit it's properties)

> then you may get a stacktrace. > > or run lazarus.new.exe, in the debugger, in lazarus itself. I never did this... can you explain, please?

assuming you compiled lazarus with -g -gl (and maybe -gw) and you did NOT strip symbol info; and ideally you did NOT smart-link:

- open the lazarus.lpi (from the ide directory)
- use "run param" from run menu, to specify the new exe (and the correct -primary-config-path)
- press F9

move the windows of the debugged Lazarus, so you do not mix them with the old one....

IIRC (at least with the version I use, 6.6.4) zeos doesn't clean the compiled units (.o and .ppu) and hardcodes its output directory to "build" (packages/lazarus/build). Try deleting all files there and see if it helps (though I think it just caused building errors, not the run-time error you are seeing).

Bye

I never had a problem with installed packages, but I always upgrade in place.
I use SVN to update my sources / but using install ,and installing the new version in the exact same place than the old should work too.

I can't comment on make, is use the build option from the menu.

And last not least (because you had problems finding system.ppu). If you get errors like this, somewhere your configuration (search path) is wrong. In this case if it compiled while old ppu files where in-place, it is expected that it would not work (as versions would be randomly mixed)
If your fpc was (as it is on normal windows installations) inside the lazarus directory, then find the fpc.cfg and make sure it has the correct -Fu paths. Same if ou rename/move the fpc directory.

Thanks for the explanation. If necessary, I will try this all. I will do more tests (not now because I'm not with my PC).

Marcos Douglas

I use the 6.6.6 version that was compiled with the same FPC version... so, IMHO that is not the problem.

Marcos Douglas

I want to continue with a stable version (FPC and Lazarus) before migrates. I use SVN too, but I have one directory for each version of FPC or Lazarus.

I have a different directory for each FPC. See below my directories: c:\freepascal\compiler\2.4.5
c:\freepascal\compiler\2.6.0
c:\freepascal\ide\laz\0.9.30
c:\freepascal\ide\laz\0.9.31

Each FPC has your fpc.cfg (but they are equal).

Marcos Douglas

I did not used these tips (yet) but I think something wrong in "Lazarus Build menu command", trunk version.
I got the new sources of trunk; compiled with fixes_2_6 (2.5.1) with sucess; open the IDE (using my pcp directory with my environment and packages configurations) and clicked 'Install/Unistall packages' and chose one package just to "refresh" the packages to show in component bar; Save and Build button; the IDE reopened with sucess.

So, I tried to compile the IDE using Tools/Build (Clean Up + Build All) and I got the same error (printscreen) for the first mail on this thread.

So, I compiled Lazarus with lazbuild tool using the same PCP and... everything worked.

Marcos Douglas

I created a new thread because I think that some is wrong with the Build command in IDE.
