Vogel via Lazarus írta: I can tell you here the same as in the related bug report https://bugs.freepascal.org/view.php?id=30617, this isn't a bug it is not happy design. You want that the scrollbox height is increased, but then the Panel2 height is increased too. Simple remove anchored bottom of Panel2 and the loop is gone. You wrote on the tracker: "You have anchored Panel2.Bottom to no sibling and Panel3.Top to Panel2.Bottom. When you now change the height of Panel3, that it doesn't fit in the scrollbox anymore, the scrollbox is resized. With resizing of the scrollbox, Panel2 is also resized (because its Bottom is anchored). Now Panel3.Top is moved too and Panel3 doesn't fit in the scrollbox anymore. And repeat." I understand you(r description) except one thing. "Panel2 is also resized (because its Bottom is anchored)" Why you think Panel2 is resized? When height of Panel3 increased and the vertical scrollbox showed up, height of scrollbox not changed nor top of Panel3. Attached two pictures. One before resized Panel3 and one after (pressed Continue on the loop error message). You see top, bottom and height of Panel1 and Panel2 is same as before. So top, bottom, height of Panel1, Panel2 and ScrollBox1 not changed. Why got the loop error? Only height of Panel3 changed. Width of Panel1,2,3 changed, okay but why this block the work of vertical anchoring? Gabor -- ___ Lazarus mailing list Lazarus@lists.lazarus-ide.org http://lists.lazarus-ide.org/listinfo/lazarus
[Lazarus] Cross Compile to Arm
Having trouble cross compiling an fpc library.
(Linux x86_64 -> Linux Arm using install from fpcupDeluxe)
Lazarus 1.9.0 r55116M FPC 3.1.1 x86_64-linux-gtk2
library Project1;
{$mode objfpc}{$H+}
uses cmem, Classes;
begin
end.
This fails with error code 256 and 'error whilst linking'
Sometimes gives msg of 'add -fPIC' which I have done, but then moves on
to different errors.
It is the 'cmem' addition causing the problem, but not cmem itself (just
within a library)
The same system cross compiles standard applications (fpc and lazarus)
correctly, seems related to libraries only.
Any ideas at all appreciated (probably a compiler/linker switch I need
to pass - but there I am lost)
ps. kudos to whomever created fpcupDeluxe.

It is nearly the same as in the bugtracker but with aligned scrollbox and a scrollbar to switch the height of Panel3. Is it so as you want? No. Attached (I hope ) a better example. The user can resize Panel2 with the Form and can resize Panel3 with the TrackBar. But want higher Panel3 than the available space. For solve this the whole thing sit in a ScrollBox. And the "InvalidatePreferredSize loop detected" problem breaks this solution. I completely don't understand why Panel3 not resizable to lower than border of the ScrollBox. Panel3 not have a bottom anchor. From my POV (and brain) the anchors are correct. Panel2 anchored to bottom of Panel1, Panel3 anchored to bottom of Panel2 and bottom of Panel3 not anchored.

[Lazarus] Lazarus Release Candidate 2 of 1.8.0
The Lazarus team is glad to announce the second release candidate of Lazarus 1.8. This release was built with FPC 3.0.2. The previous release Lazarus 1.6.4 was built with FPC 3.0.2 too. The Linux releases are built with FPC 3.0.3 r36408 due to bug https://bugs.freepascal.org/view.php?id=31629 Here is the list of fixes for Lazarus 1.8.x: http://wiki.freepascal.org/Lazarus_1.8_fixes_branch Here is the list of changes for Lazarus and Free Pascal: http://wiki.lazarus.freepascal.org/Lazarus_1.8.0_release_notes http://wiki.lazarus.freepascal.org/User_Changes_3.0.2 The release is available for download on SourceForge: http://sourceforge.net/projects/lazarus/files/ Choose your CPU, OS, distro and then the "Lazarus 1.8 RC2" directory. Checksums for the SourceForge files: http://www.lazarus-ide.org/index.php?page=checksums#1_8_0 Minimum requirements: Windows: 2k, XP, Vista, 7, 8, 8.1 and 10, 32 or 64bit. FreeBSD/Linux: gtk 2.8 for gtk2, qt4.5 for qt, qt5.6 for qt5, 32 or 64bit. Mac OS X: 10.5 to 10.12, LCL only 32bit, non LCL apps can be 64bit. The svn tag is http://svn.freepascal.org/svn/lazarus/tags/lazarus_1_8_0_RC2 For people who are blocked by SF, the Lazarus releases from SourceForge are mirrored at: ftp://ftp.freepascal.org/pub/lazarus/releases/ and later at (after some time for synchronization) http://mirrors.iwi.me/lazarus/ == Why should everybody (including you) test the release candidate? == In the past weeks the Lazarus team has stabilized the 1.8 fixes branch. The resulting 1.8RC2 is now stable enough to be used by any one for test purposes. However many of the fixes and new features that where committed since the release of 1.6 required changes to the code of existing features too. While we have tested those ourself, there may still be problems that only occur with very specific configurations or one project in a million. Yes, it may be that you are the only person with a project, that will not work in the new IDE. So if you do not test, we can not fix it. Please do not wait for the final release, in order to test. It may be too late. Once the release is out we will have to be more selective about which fixes can be merged for further 1.8.x releases. So it may be, that we can not merge the fix you require. And then you will miss out on all the new features. == How to test == Download and install the 1.8 RC2. - On Windows you can install as a 2ndary install, that will not affect your current install: http://wiki.lazarus.freepascal.org/Multiple_Lazarus#Installation_of_multiple_Lazarus - On other platforms, if you install to a new location you need to use --primary-config-path In either case you should make backups. (including your primary config) Open your project in the current Lazarus (1.6.x), and use "Publish Project" from the project menu. This creates a clean copy of your project. You can then open that copy in the RC2. Please test: - If you can edit forms in the designer - rename components / change properties in Object inspector / Add new events - Add components to form / Move components on form - Frames, if you use them - If you can navigate the source code (e.g. jump to implementation) - Auto completion in source code - Compile, debug and run - Anything else you use in your daily work Mattias -- ___ Lazarus mailing list Lazarus@lists.lazarus-ide.org http://lists.lazarus-ide.org/listinfo/lazarus

[Lazarus] bluetoothlaz package cannot detect Bluetooth LE (version > 4.0) devices on raspberry pi
I am using Raspberry Pi 3 (with wifi+bluetooth).
When using the command tool, bluetoothctl, it can detect old and new
bluetooth devices (version > 4.0).
However, using the bluetoothlaz inside my lazarus app, it can only
detect old bluetooth devices (not the BLE new devices).
I am guessing the bluetoothctl uses the new version and features in
bluez (ver 5.41) but bluetoothlaz uses the
{$linklib bluetooth}
which probably is the file
/usr/lib/arm-linux-gnueabihf/libbluetooth.so.3
which is a symbolic link to
/usr/lib/arm-linux-gnueabihf/libbluetooth.so.3.18.13
which might probably be compiled with old versions of bluez (or turn off
the BLE feature).
Do you think my guess is correct?
If yes, can anyone point me to how to update the libbluetooth.so ?
Should I compile a new .so? How (I am bad in linux).
Thanks a lot in advance.
Dennis
