You can use Linux API calls directly from Delphi 10.2 and up

Posted by jpluimers on 2018/07/05

Paul TOTH figured this out:

you can use any Linux API but it’s not trivial.

  1. you have to install the “dev” library under Llinux, like “apt-get install xxx-dev” for the xxx API
  2. you have to update the Linux DSK in Delphi
  3. you can declare the API as externals function as usual
  4. now you can compile and deploy the application.

If you miss the steps 1 or 2 you’ll have a linker error.

And there is this great blog post that I found later by [WayBack] Allen Drennan: [WayBackImporting third-party Linux libraries on Delphi 10.2 Tokyo – grijjy blog

I totally forgot that Delphi has had a function to get the current executing thread – Stack Overflow

Posted by jpluimers on 2018/07/05

While updating some old code fiddling with the[WayBackGetThreadId function, I wanted to have some TThread wrapper around it. I had totally forgotten there has been already a means for this since Delphi 2009 (which initially had a bug, but that was worked around at first and fixed later): [WayBackCurrentThread.

The latest version of Delphi, Delphi 2009, has a CurrentThread class property on the TThread class.

This will return the proper Delphi thread object if it’s a native thread. If the thread is an “alien” thread, i.e. created using some other mechanism or on a callback from a third party thread, then it will create a wrapper thread around the thread handle.

Delphi 10.2 Tokyo: they did not fix the broken documentation tab in 10.2.2 2004, but it is an “easy” fix to do yourself

Posted by jpluimers on 2018/06/06

Since the fix is on the forums server (singular!) and that one tends to be squirrel driven lately, here it is in full via [WayBack] I see they didn’t fix the broken documentation tab in 10.2.2 2004 (professional). It’s not a show stopper but a nuisance to fix oneself. And for new dev… – Herbert Sauro – Google+ and [WayBack] I have installed Delphi 10.2.2 and the Documentation tab is all stuffed up ( see picture ). I know there is a html template page for the welcome tab, bu… – Tony Danby – Google+

In C:\Program Files (x86)\Embarcadero\Studio\19.0\Welcomepage\en

Edit Documentation.htm and insert the one piece about the innerWidth

function setFrameURL(url)
                document.getElementById('load_html').src = url
                $("#load_html").css("display", "block");
                var height = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight;         
                var width = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;         

It works and takes up the entire page after you restart the IDE.

If it gets up:

Do NOT download the Embarcadero patch for RAD Studio 10.2.2!

Posted by jpluimers on 2018/02/11

[WayBack] Embarcadero just released a patch for RAD Studio 10.2.2. It breaks linking projects with runtime packages, like GExperts, any other IDE expert and probably also most component packages. – Thomas Mueller (dummzeuch) – Google+ in a response to [WayBack] RAD Studio 10.2.2 Tokyo February 2018 Patch available now at This patch for RAD Studio 10.2.2 (build 2004)… – Marco Cantù – Google+.

RSP-19914 (by Thomas Mueller)


After installing the RAD Studio 10.2.2 Tokyo February 2018 Patch I can no longer compile any project with “Link with runtime packages”.

Error message:
[dcc32 Fatal Error] Project1.dpr(5): E2225 Never-build package ‘vcl’ must be recompiled

Steps to reproduce

1. Create a new VCL project
2. Open project options
3. Select Packages -> Runtime Packages
4. Set “Link with runtime packages” to true
5. Close dialog with OK
6. Compile the project
-> Error

You might have noticed that the MVP logo is no longer on the blog. It got revoked because I was too critical. Given releases like the above, I can’t stop being critical in a public way as the internal ways to effectively voice criticism that used to work in the past stopped working a long time ago.

Not just the MVP was revoked, the account to which the MVP was attached got killed without notification. That account also had the tech-partner licenses attached: the ones I used to support Delphi open source projects. Which means I do not have any Embarcadero provided licenses to support open source Delphi projects any more except the ones I own (the most recent ones being Delphi 2007 and XE4).

Many people in the Delphi community even refuse to become MVP because formally the MVPs are not allowed to be be critical publicly. Which means these community members have a limited list of Delphi versions they can use to support and test their open source projects with.

I am glad for the time I could use those licenses to support open Delphi source projects, but alas, that time is over. I still like the concepts of Delphi as those are strong. I don’t like how Embarcadero handles their infrastructure and product quality.

In the next 2 years there will be Delphi posts on my blog as that’s about the depth of the posting queue right now. After that: time will tell. For the last decade or so, I’ve spend more free time supporting Delphi than spending time on paid Delphi projects. That won’t last forever.

For now I’m going on a two week holiday tomorrow after which I will be available for new projects.

If you use Delphi or RAD Studio 10.2.2, ensure you have the latest one installed (build 2004) as it fixes some binary DCU incompatibility bugs 

Posted by jpluimers on 2017/12/19

Not all updates are equal, so if you use Delphi or RAD Studio 10.2.2, ensure you have the latest one installed (build 2004) as it fixes some binary DCU incompatibility bugs in the old one (build 1978).

You can get the web-install for that build from [WayBack] 30806 RAD Studio, Delphi, C++Builder 10.2 Release 2 Web Install which states:

We have updated RAD Studio 10.2.2 to address an issue that caused incompatibility problems for a number of third party components.This build (build 2004) replaces the previously released RAD Studio 10.2.2 build (build 1978).

The updated 10.2.2 build requires a full uninstall and reinstall. You will be able to preserve your configuration settings as part of the reinstall.

The new 10.2.2 update build 2004 fixes errors in the old 10.2.2 update build 1978 like:

  • when compiling “F2051 Unit %s was compiled with a different version of System.Generics.Collections.TArray.Sort”
  • when loading BPLs “Cannot find entry point…”

Via: [WayBack] Looks like there was an update to the update. “This CodeCentral entry was updated on Dec 17, 2017 We have updated RAD Studio 10.2.2 to address an issu… – Lars Fosdal – Google+

In that thread, various people have confirmed this build indeed fixes these issues.
