This problem is solved! I found that if I cleared the linker heap settings (in project | options | linker) and then tried a build the correct linker did run (so the can't create task ILINK32 error message is a bit of a red herring - the task called ILINK32 creates a call of ilink64) but it gave an "out of memory error". Entering heap sizes back in again (as per the embarcadero documentation on "linker out of memory" issues) gave me a project that links ok. OK : so not actually sure why I had to do this - but it has solved the problem.

I get the same problem with and without TwineCompile. I use TwineCompile for all C++ projects - for the clang compilers any reasonable project without TwineCompile becomes unmanageable because of the compile times.....

I have just created a new trivial Clang64 VCL project (one form, two buttons). This compiles and links ok with 11.2. When I look at the section of the build output text related to the linker it begins as follows: Linking... Target _PerformLink: Target _PerformBCCILink: d:\program files (x86)\embarcadero\studio\22.0\bin\ilink64.exe -G8 -L.\Win64\Debug;"d:\program files ie it is using the ilink64 linker. So I am pretty sure that my problem is that 11.2 is for some reason trying to link my large project using the wrong linker.... Anyone know why this might be or how I can force this to use ilink64 ?

Hi David P, Really appreciate your suggestion. Have tried doing a manual delete of all temporary folders - no different. I already use a different tempororary file for each build option (for this VCL Win64 project I only have a debug build and a release build as the two targets). You don't mention my note about "shouldn't it be using ILINK64".... Do you agree with this statement or am I wrong here?

It is true: you cannot use the Classic compiler to compile GoogleTests. But there is nothing (or at least normally very little) to stop you using the Classic compiler for your main project but to use Clang32 for your unit testing project

My mistake ! sorry for confusion. The correct link is.... https://cigolblog.wordpress.com/2022/05/12/using-google-tests-with-classic-compiler-projects/

Hi Camilo, It is entirely possible (and maybe advantageous) to write your main (typically legacy) project using the Classic compiler but to write your unit tests using clang32 and the Google Tests framework. See https://cigolblog.wordpress.com/2022/05/12/using-google-tests-with-classic-compiler-projects/ The big advantages of using GoogleTests over DUnit are a) There is good documentation provided by Google out on the web b) it supports all commonly used unit testing techniques (including building mocks) c) if/when you move your Classic based project to Clang32 your unit tests will all still be valid / useful I've ditched DUnit completely in favour of using GoogleTests - even though many of my existing projects for customers are still based on the Classic compiler

Hi David P - can you remind me how to switch off the Code insight indexing in 11.2 - I can't find the check box " Index for C++ Insights" that is referred to on this help page: https://docwiki.embarcadero.com/RADStudio/Alexandria/en/Code_Insight_Reference#Error_Insight

Interesting - I seem when I successfully compile and link my GoogleTests unit tests for this project I get this line in the console output Linking... Target _PerformLink: Target _PerformBCCILink: d:\program files (x86)\embarcadero\studio\22.0\bin\ilink64.exe -G8 -L. < all my google test files are listed here> Build succeeded. 0 Warning(s) 0 Error(s) The fact that the error messages for the main project (previosuly reported) are referring to "ILINK32" makes me wonder if the 11.2 has got mixed up and is trying to call the 32 bit linker....

I don't know if this helps (it looks like more of the same...). The TwineCompile "console output" shows all 354 file compile ok and the resource compilation goes ok. It then reports the following for the linker error.... Done building target "MakeObjs" in project "MyProjectNameHere.cbproj". Linking...

Beta testers are not magicians (at least none of the ones I've ever met are). If you don't file an RSP it is much less likely that the bug you vaguely describe here ("problems with ctrl+click to open files") will be fixed.....Please do file an RSP.

That's a little lazy.... Here's the link https://quality.embarcadero.com/browse/RSP-38884?jql= It would be interesting to know if the same problem exists on 11.1 - does anyone have time to check this ?

It would be really valuable to everyone if you could file this bug on the Embarcadero Quality Portal https://quality.embarcadero.com/secure/Dashboard.jspa

Can you give a brief sample code of the kind of thing that you think fails sometimes, even though it "works" in your brief sample. This could well be an example of doing something that C++ is allowed to use the "undefined behaviour" get out (undefined behaviour often tends to one of either "a complete crash" or "sometimes works and sometimes doesn't"

A strange question to ask. You are the person who can generate the fault you are trying to describe. So only you can really judge if the same problem exists when the correct set of circumstances are made to exist in another (eg open source) project....

I would be wary here. The field defaults to read only because it is a calculated field. Why would you want to change the value (unless you are trying something very dodgy?) of a calculated field. This strikes me as the sort of thing that should ring an "alarm bell" with the question: "am I designing my code the best way ?"

I can see a sample .gitignore file for Delphi at https://github.com/Embarcadero/RADStudio11Demos. But I can't find an equivalent for Embarcadero C++ projects. Does anyone know of one up there (or anywhere else) (and is it up to date to include ignoring the _astcache folder contents)?

RAD Studio, C++Builder 11.1.5 is released today (15th July 2022). Can anyone find installation instructions for this ? ie do I need to uninstall RAD Studio 11.1 first and then do a complete reinstall or does the install need to go "on top" of my existing installation? I am sure this must be on the Embarcadero wwww site somewhere but I can't find it ! Send us a URL if you know better than me, please....

I did read David's blog : I am not sure that the line you emphasise should be interpreted to mean uninstall the old version and then install the new one. I thought it means only that you don't have to worry about if you have got the other hot fixes in or not. Actually I tried to install it "over the top" of 11.1 and the installer detected the existence of 11.1 and uninstalled it (keeping registry settings) and then installed 11.1.5 - The installation went smoothly.

If you have RAD Studio (ie you also have C++ Builder) then the C++ FMX header files may be useful here.... Not sure about copyright / license restrictions on their use though....

I have a C++ Builder (10.4.2) Windows 64 bit VCL application (clang64). Whilst it is running I want to start an external (third party) windows 64 bit exe console application and whilst this runs to completion I want my VCL application to capture (and I will write code to process) the) text output that the third party exe file sends to "standard output". Ideally I want to do this without the user being aware that it is happening. It's easy to run an external console application in it's own shell, but how do I redirect the output from this external console application into my (already running) VCL application?

Thanks Remy - as you rightly say, it's not too difficult to get the console interface working. Slightly harder to write a unit test to prove that unicode chars are handled ok. But I got there in the end. Thanks for pointing me in the right direction.

If you want to compile Delphi you have to get RAD Studio 11.1

or is the TEdit bound to the data source by LiveBindings ? (Right click on the TEdit and select BindVisually....)

Frost.Brutal : Thanks for this instant manual on "how to configure tools" ! I had never really looked into this feature of the IDE and I can immediately see how it can be useful !
