then maybe big, core functionality, non-UI code sharing between mobile,
desktop and web platforms would be a good one. no LCL, but at least RAD
style development with lazandroidmodulewizard is fun enough.

the 'good' part is that it doesn't crash unexpectedly ;) 
but I found some ways to get a project built, without warnings or errors,
and then have it not run on the target device while programming
a listener for a button...

(luckily it was just some implementations missing while c&p programming, so it
was semi-not frightening already ) 

the whole Android-Java thing is a right nightmare to comprehend, to me.

Android and AndroidStudio are bad against Lazarus? Yea I think but it
has power of millions of users and it has a standard for UI and its good
so if any programming language want to play it its field it need to be
clean as native but easier to write with a better structure.

[Lazarus] Cross Compile setup unsuccessful

[JuuS]

Hello,

I work with Lazarus 1.4.0 on Kubuntu 14.04 with an x86_64 system.

I wanted today to make my Lazarus cross compile to win32, win64 and
linux 32 bit.

I followed the directions at these two pages:

For windows the make all and make crossinstall appeared to have finished
properly with no errors. But when I attempt to make a cross install of
win32, for example, in Lazarus it says /usr/bin/fpc does not support the
target i386-win32


As for the make all for Linux i386 it fails with:

I tried Android Studio, only just a simple example project (bluetooth chat with 
mods)
import (mods to make the bluetooth part connect to a bluetooth-serial type 
endpoint)...

It is painful.

They went to great lengths to name every other element of that ecosystem
DIFFERENT than people coming from other contexts may recognize. 

I mean, you know what an 'activity' is ? At first glance? ...

The standard controls are well, standard; and no clear path/explanation to 
install any 
non-standard ones (like, how would you program up something like analog gamepad 
buttons?)

(one might just about recognize a Button class, and c&p its creation&usage to 
get what one wants,
 within the bounds of same class... ok it works... even got progress/trackbars 
to work as joysticks...
 but the rest is so baroque and unhelpful and unintuitive, I can't bear to look 
at it any more... 
 too many variables. oh, and what is a 'listener' again ?)

Now try merging code from another example (e.g. accelerometer/gyroscope 
handling)
with the serial bluetooth dongle/chat example. In Java. 

I'm still struggling.

Not helped by, that my 4 year old i5 24XX CPU turns its fan into a small 
jetplane (noise-wize)
wile just browsing code trying to figure things out for more than half an hour.

Why? It's not as though he's trying to add non-open components to the 
published IDE and expecting other people to use them, and since there's 
no requirement to publish stuff you build using an "open" license (GPL 
etc.) I don't see that putting copy protection on it makes any 
difference at all.


The format of binary-distributed libraries etc. could prove to be more 
of a problem, and consulting Jonas et al. in the fpc-pascal mailing list 
might be necessary. However I would say that while I recognise that 
changing the protection "dongle" is obviously a non-starter, I'd be very 
suspicious of any protection scheme which relies on unpublished source 
code: such a thing would smack of "security by obscurity" which is 
universally considered to be a Bad Thing.

Wrong is typo here but its likely to be true.In Android and iOS I didn't
saw ant foreign language do a good job.If you saw any good app with
beautiful standard UI tell me.

I mean if they are going with AsndroidStudio probably they should
continue with that,just compiling for a device is not a good reason to

Closed source 3rd part stuff might be problematic.

As for imposing copy protection on software... I have no problem with
that at all. I do it myself, otherwise how am I going to make money off
software that took me years to develop. Not everything in this world
needs to be open source. Developers need to make a living too. I know
this is a fine line. eg: I personally think development tools (compiler,
IDE and debugger) should be open source. 3rd Party components should
come with source code, and applications being developed can be anything.

For that reason I refuse to purchase any software components that don't
include full source code. Some ISV's can be very slack with support, or
very slow to progress. eg: Digital Metaphors don't support FPC or
Lazarus with their ReportBuilder product. Yet I knew somebody that
bought it will full source code, and managed to port it themselves. Full
source code gives you that option, and you don't have to be locked in or
at the mercy of the ISV.

Either way, it is good to ask the ISV's to support Free Pascal and
Lazarus. Always raise the interest.

Why ?

If you use the JVM compiler, the app uses the Java SDK, and it will look exactly like the 
android native apps look, because then it IS a native android app.


Of course, you can't use the LCL then.

Good question. Has somebody tried CodeTyphon or KZDesktop in a Mac?
Those systems have similar tabs.

Otherwise we can have few weeks pause before implementing this
feature. Balázs is having holidays, Maciej can fine-tune his changes,
I also have many other things to do. We are not in a hurry really. I
am quite confident we get this feature into Lazarus during July.
I still hope there will be one version of the code accepted by all
parties instead of competing versions.
