Werner thank you, i will make a try and i will look for the changes, 
because i found other (older) components they have some trouble with 
frames (DirectShow) too. Next week i can spend some time to check this 
with a fresh installation to avoid side effects.

Forum user "handoko" reports some issues with RC1 in 
http://forum.lazarus.freepascal.org/index.php/topic,37022.msg247603.html#msg247603 
(and 
http://forum.lazarus.freepascal.org/index.php/topic,36907.msg247608.html#msg247608), 
among them the "double-keyboard" error under Ubuntu again. Maybe someone 
more knowledgeable than me can have a look at this.

This happens when "Create a seconary installation" is checked. And I

guess this is intended. But why should a secondardy installation be

I implemented it in r54976 and made it default because all 8-bit string 
types are equivalent for the compiler, so it makes perfect sense not to 
mix them; if I am not mistaken.

Fixed.

The Lazarus devels only support the last two FPC releases, which means
3.0.0 and 3.0.2.
But as long as FPC 2.6.4 only needs a few IFDEFs, patches are welcome.

Looks like you may have the unit "windows" in your uses clause.

Either move the Windows unit in front of the SysUtils unit, or use
SysUtils.GetEnvironmentVariable

An "In" was limited to a range of 0..255.

As far as I know, this is still so, but a compiler guru will need to confirm.

If (NeededWidth in [1..MaxWidth]) was used for speed reasons, I'm not sure
that that is a good idea.

Function GetEnvironmentVariable(Const EnvVar : AnsiString) : AnsiString;
Function GetEnvironmentVariable(Const EnvVar : UnicodeString) : 
UnicodeString;


But Code Completion offers three functions named GetEnvironmentVariable:
The Ansistring function and the Unicode String function above plus
"GetEnvironmentVariable(lpName: LPCSTR; lpBuffer: LPSTR; nSize: DWORD): 
DWORD".


Seems, Lazarus tries to use only the latter.

No, I don't have another GetEnvironmentVariable.

You can reproduce this easily:
Put a TButton Button1 on a form.
In the OnClick Event for this button write "Button1.Caption := 
GetEnvironmentVariable ('computername');"


Version Info (Thank you for this hint):
Lazarus 1.8.0RC1 r54919 FPC 3.0.2 x86_64-win64-win32/win64

Lazarus claims, the is no valid parent and didnot load and crash. It 
is only happen if you use frames ? The trouble is, i can only shutdown 
Lazarus with the Processmanger.

This is confusing: Are you using Laz trunk (v1.9) or 1.8RC1? I don't see 
an issue with WorksheetGrid on frames with Laz trunk. Can you post a demo?

I also see another issue with the form designer - when i have two forms
open, despite which one i activated last, the one i created something first
is always being focused even if i try to create something in the other
form. Note that this happens in 1.8RC1 and SVN with and without the patch i
mentioned above.

Is this the correct way to report my finding? As a non professional I am 
not sure.


Lazarus 1.8 RC1 under Win 10 (64):
"GetEnvironmentVariable('computername')" doesn't work.
When compiling, it returns "Error: Wrong number of Parameters specified

KDE Plasma is using Qt5, but ide is Qt4, so in Qt4 config you can set 
same fonts as they are in KDE Plasma and they will be exactly same.
It's bug in KDE, since applying any setting to Qt5 (via KDE settings), 
should apply same applicable settings for Qt4 applications.
Besides that, you can build cbindings for Qt5 and rebuild lazarus 
against Qt5 widgetset to see if there's any difference.

Yes it is.

You use 150% scaling (96 DPI = 100%), so Lazarus is also scaled by 150%.

It's a new feature :)


Well, if it is, it's broken: every other application (either kde or gtk) 
shows fine, the only ugly one is lazarus :-(
OTOH in the plasma control panel I see no option to set the dpi, the 
only one I could find is "screen scaling" which is set at the lowest 
possible value (1), if I set it to 3 the preview shows elements (fonts, 
tabs, buttons, etc.) 3 times as big (duh!).
There's a section to select the gtk theme but it doesn't have an option 
to select the dpi either (just the gtk2 theme, the gtk3 one and the font).

isn't included.

Is this version still supposed to work with fpc 2.6.4?


Yes.


Well, in that case you'll have to comment/ifdef the use of "Default" in 
components/codetools/finddeclarationtool.pas

It seems it's just used to silence a warning.



I applied the patch. Thank You!


Thank you

== 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 1.8RC1 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 RC1.
- 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 RC1. 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
