Lazarus Release Candidate 2 of 4.0

[dbannon]

You can always start Lazarus with a config dir of your choice. Putting aside convention, it can be anywhere you have write access to.

Use --pcp=/some/path/to/lazarusRC2


or put the above (with no leading space) in a file call 'lazarus.cfg' in the top dir of the particular lazarus install you want it applied to. Then, when you start lazarus, it reads the config and uses that dir.

In this manner, you can have as many independent Lazarus installs as your hard disk will contain.

FPCUpDeluxe makes a script to do this for you but you are far better off understanding the process and controlling it yourself.

If you can find the file with the anchor layout (again, sorry not sure which) => report a bug and attach it...

Ok, I will try to reproduce it again.

It happened again, twice on another PC with a different Windows version.
Both times it happened after recompiling the IDE. The second times it was even worse than before, I could not fix it by moving the headers, the mess was total.
I uninstalled *dock*.lpk and a message was shown "Invalid property, shall it be removed...". The message was reasonable, since I moved a Published property of an LPK to the Public section. But this message should have appeared even before uninstalling *dock*.lpk.

Thanks !

Now i compile with Linux 64 on ARM.
I am waiting to compile on ARM64, MIPS, POWER PC 64 and LOONGARCH64.
On MIPS there are a lot of libraries not found on Lazarus 3, on others there is just libpangocairo.
I cannot compile on IOS ARM my packages.

I am waiting to compile on ARM64, MIPS, POWER PC 64 and LOONGARCH64.

I routinely compile on Arm64 linux (gtk2 and Qt5) and debian compile on Power64el (Qt5), as I understand it, without any problems except the known PIE hardening one.

I cross compile to MacOS Arm64, have not personally tested the result but have been advised it works.

I think first GNU Linux cross compile from Linux 64 to other Linux works good.
But when i close Lazarus and open it again it does not work. This is why i could create Loongarch64 and maybe ARMHF a time.

Now i am saying me that a virus empeaches me to import medias on GEDCOM. Payed genealogy softwares do not provide this option so they have could tell a hacker to not enter a function that is passed on debug.

When I change the colour for the form in design mode it is not changed in the editor. But when I build the app and execute it, the displayed colour is as set.
Is this the expected behaviour?

I don't see that behavior using Linux + KDE with a stock theme in use.

[Martin_fr]

Maybe its a limit in the docked form designer? Needs to be tested.

[CM630]

Indeed, when *dock* packages are uninstalled, the colour of the form is visibly changed in the IDE.

[Martin_fr]

My guess: ParentColor.

Forms to have that, even if not published, they inherit it from TControl. And if it is true, then the docked form editor puts the form into a parent.

I have found the problem with libpangocairo.so on Linux X86 64.

Lazarus searches libpangocairo.so, not libpangocairo.so.0.

There is a lack for FPC UP DELUXE. It downloads only gtk and qt5 libraries, not qt6 libraries.

for POWER PC 64, there can have this error :
Error: /home/matthieu/fpcup3.0/cross/bin/powerpc64-linux/powerpc64-linux-ld:/home/matthieu/fpcup3.0/cross/lib/powerpc64-linux//librt.so: file format not recognized; treating as linker script

That is why dev packages exist, at least on Debian based distro's. If the distro you use does not link your libraries for you then you should do it manually.

Bindings for qt (but afaik also qt6 itself) is a work in progress. Feel free to supply patches/merge requests.

for POWER PC 64, there can have this error :
Error: /home/matthieu/fpcup3.0/cross/bin/powerpc64-linux/powerpc64-linux-ld:/home/matthieu/fpcup3.0/cross/lib/powerpc64-linux//librt.so: file format not recognized; treating as linker script

Typo in this message or Typo in (output from) FPCUp ?

BTW: FPCUpDeluxe has its own thread. Issues regarding FPCUpDeluxe do not actually belong in this one (unless it is clear that there is a direct relation with this release).

It fails to install dcl_rxtools.dpk from online package manager (cannot compile packadge)
