r1042 fails to compile under FreeBSD

[Graeme]

Hi,

[starting a new thread with more specific subject line]

I've just checked out the latest LazPaint from SourceForge and tried to compile BGRABitmap under FreeBSD as you requested. I tried with FPC 2.6.4, 3.0.1 and 3.1.1 - all give the exact same result.

It fails on the newly introduced LoadFromDevice() methods but I can't actually understand why FPC complains. The declarations look correct to me, but then it is early morning. ;-)

Good news is that if I revert the recent changes and move to r1039 then BGRABitmap package compiles without error on FreeBSD. I haven't tested BGRABitmap yet, but it compiles on r1039.

It may be related to the type THandle if it is redefined in two different units. When you CTRL-Click on the types in both method declarations, do you get to the same unit?

[Graeme]

Well done, you hit the nail on the head.

In the Interface section of the unit a Ctrl+Click takes me to SysUtils.THandle, but in the Implementation section of that unit it takes me to LCLType.THandle.

ps:
All of the examples in the bgraaggtest directory compile and run just fine under FreeBSD. So other than this THandle problem, it seems BGRABitmap works without issues on FreeBSD 64-bit. Next I'll try the BGRAControls and see how they fares.

Today I tryed to install bgrabitmap on lubuntu and failed.. i'll try again don't remember exactly the problem, something like "tbgraptrbitmap" missing.

Umm, this thread was about FreeBSD only - Lubuntu is Linux. May I suggest you rather start a new thread - that way people looking only at the subject lines know the real topic of a message thread.

In fact it is a bit related. It was a problem with Gtk unit. Thanks 007.

It is fixed in version 8.3.1.

By the way Graeme, does it compile on FreeBSD now?

[lainz]

Nice! Hope I can compile my bgra programs under linux, I not tested them in long time in that OS.
