Lazarus Release Candidate 1 of 1.8

[zeljko]

I can confirm, even with Laz trunk (win 10/64 bit, Laz-trunk/fpc3.02/32 bit). Is there a valid bug report for it?

Maybe, but such example is needed to fix it...or open new one and attach example from above screenshoot.

Tried today to install fpc + lazarus on Linux Mint 18.1
fpc_3.0.3-r36152_i386.deb  installed without problems.
fpc-src_3.0.3-r36152_i386.deb also installed without problems.
lazarus-project_1.8.0RC1-0_i386.deb gave this error message :

Error: Dependency is not satisfiable: fpc(=3.0.3) | fp-compiler (=3.0.3)

What can I do ?  Thanks

Al

Problem solved, though I don't know how and why....
I simply reformatted the partition, reinstalled Mint 18.1 from scratch, then, before trying to install fpc and lazarus, did an apt update and an apt dist-upgrade...  this time both fpc and lazarus installed without fusses, and my program did compile and run correctly.

Still have to understand why some lcl components do show differently when the program is executed under a different distribution of Linux, but this a topic for another forum...

Because themes for GTK2 are different in those distributions. LCL uses native controls instead of custom drawing them.

Thanks for the explanation. At this point, is there anything I can do to be reasonably sure that my program behaves exactly, or almost exactly, on the users' machines as it does on mine ? Are those GTK2 themes changeable programmatically ?

Maybe yes, google for $HOME/.gtkrc or similar names...maybe $HOME/.gtk2rc ...

No. They idea is that a user can customise his environment as he pleases.
All applications should follow the customised theme and thus look consistent.
A themable desktop system is a good thing, I don't know why anybody would want to make an alien looking app which does not respect the user settings.

Linux distributions by definition are diverse because of competing desktop and widget systems.
Even so there is effort to get consistent look between applications. For example my KDE has specific settings for GTK+ applications, and they look more or less like KDE apps do. Their level of desktop integration obviously does not match with the real KDE apps.
Other desktop environments have similar efforts.

A themable desktop system is a good thing, I don't know why anybody would want to make an alien looking app which does not respect the user settings.

The problem is that, using Linux Mint 18.1 and Lazarus 1.8 RC1, I wrote a program with a couple of sliders, which I set of color Silver.
When run on different distribution, the sliders were of color black, thus not visible on the form background, also black....

Hello! I have a computer with 32-bit Windows. I wanted to compile for Win64.

I have installed the compiler:
lazarus-1.8RC1-fpc-3.0.2-win32.exe
Then I installed the cross-compiler:
lazarus-1.8RC1-fpc-3.0.2-cross-x86_64-win64-win32.exe

I lauched Lazarus and pressed F9. The default Project1 compiled and run successively.
Then I choose Project -> Project Options -> Compiler Options -> Config and Target -> Target OS (-T) -> Win64 -> OK.

The following warning appeared:
[Warning]
The current FPC has no config file. It will probably miss some units. Check your installation of fpc.
[OK] [Ignore]

And when I attempted to compile, the following errormessage appeared:
Compile package FCL 1.0.1: Exit code 1, Errors: 1
Error: Illegal parameter: -Twin64

[Thaddy]

Did you also compile everything for win64? rtl, fcl, packages?

[jc99]

@Thaddy: that's normally part of the lazarus-1.8RC1-fpc-3.0.2-cross-x86_64-win64-win32.exe package
but
@mogenslarsen: You only mentioned the win64 did you also set the the TargetCPU to x86_64 ?
 [edit] Because i386_win64 is an illegal combination (Maybe a better Message : Illegal parameter -Twin64 in combination with -Pi386 would help)

[mogenslarsen]

Thank you. After I changed "Target CPU family (-P)" from default to x86_64 the problem was solved.
By the way, I need not to change "Target processor (-Cp)" from default. It seems to be inconsistent and confusing for me as a novice.

Use fpGUI?

Bart

Sorry for being so dumb, but I tried without much success...
I followed the instructions in the  http://wiki.lazarus.freepascal.org/fpGUI_Interface page,
my project compiled up to a given point, then an error message appeared, saying :

fpguiwscalendar.pp(38,28) Error: Identifier not found "TWSCalendar"

Maybe I missed some important steps ?
