Compile for one platform from another

[Saki]

Look, the event handling under Windows is different than under Mac and Linux.
There are codes that give you output on Windows, but no output on Linux and Mac, or it hangs, or is incomplete.
This is not a bug of PB.
You don't ask for a feature, you ask for things that don't work, since the OS internally work differently !

Another thing, for example.
Linux has gtk3, which technically can never be absolutely compatible with Mac or Windows, because it works completely different.
Now comes gtk4, which makes the gap even wider.
That's why there is now qt for PB, but that's not a solution for the future either.
The OS will become further and further apart:
And then try marrying a fox to a duck


Best regards Saki

I'm asking to be able to cross-compile not for Linux executables to magically run on Windows.

[Saki]

But that doesn't make sense if you can't test the codes on every OS.
And there is no difference between testing and compiling.

Oh, OK then... perhaps Fred should just shut down the Feature Requests and Wishlists section of the forum <eye-roll>

I don't see anything wrong with making a Request, including this one. Some things may be easy, other things not possible. At the very least requests bring an awareness and discussion of peoples wishes and needs. Even if a request is never fulfilled, other good things may spin out of it. Only my opinion!

Personally I'm already happy with the results from working on three platforms, but always there could be scope for further improvements.

Actually it's what you thought I meant that didn't make any sense - why would I want to run a Linux executable on Windows when I could just compile a Windows executable?

Cross-compiling is a perfectly reasonable request and it's not something novel or extraordinary.

@Tenaja gave a very clear explanation of why Fred might see it as too burdensome and I appreciate the point.

[Saki]

There are licensing problems and it is not possible for technical reasons.
There is nothing more to say about this.

Best Regards Saki

Technically, it's possible. It seems he finds the maintenance overwhelming, which is understandable. He'd have to port the generation libraries to every platform, do there'd be nine instead of three... And if you add the recently promised arm output, it will be sixteen instead of four. Or, cumbersome #CompilerIfPlatform=TheRightOne statements.

Thanks for the perspective.

We should be happy with what we have with Purebasic.

You are not the first to request this, and also not the first to get it denied--and probably also not the last. Just because this one request is not honored is no reason to Throw the Baby Out With the Bathwater.

My guess is mk-soft is referring to the fact that we have the best and most long-standing cross-platform compiler, and we are blessed that most code compiles on all three platforms with very few edits. With a fourth on the horizon, Fred is undertaking his largest project yet (probably even larger than Spider Basic), and he's unlikely to stop and make a change that won't improve the code output

[mk-soft]

If you want an application to run on all OS, you need a common framework, which also runs on all OS. (Just like JAVA runtime environment).
But for the application to run, the huge framework must first be installed.

I think we don't want that either.

There is a project somewhere, where a Windows version is compiled under Linux. But for this you have to install the runtime environment for Windows (Wine). With macOS it won't work that way, because there is no such thing.

[Saki]

However, Wine must then also be 100% compatible.
It simply doesn't make sense, then you can compile on Wine,
because you have to check if the code of both OS are working properly anyway.

Has anybody tried their wsl for pb?

Wine (originally an acronym for "Wine Is Not an Emulator") is a compatibility layer capable of running Windows applications on several POSIX-compliant operating systems, such as Linux, macOS, & BSD..

* edit *
If you have an Android smartphone with an intel processor you can use the Wine app to run windows programs on that too:

pfff...

But I think it should work (at least for console applications) if you make some adjustments.
