unknown error mesage

[ldries46]

During debugging an Ada program when building a new version I got the 
following message:

gprbuild -d -PD:\ada\project\Datum\Datum.gpr -j8
Bind
    [gprbind]      datum.bexch
    [Ada]          datum.ali
fatal error: file gtk.ali is incorrectly formatted

[2021-03-16 18:40:50] process exited with status 4, 100% (63/63), 
elapsed time: 02.63s

I have already deleted all .ali files in the build directory, deleted 
the Datum.exe file, reinstalled GtkAda en even reinstalled GNAT Studio 
Community version 2020.

Who can tell me what is message means and how to eliminate that

I presume you've read this question with a similar issue? 

https://stackoverflow.com/questions/7576994/ada-strange-error-consistent-version-of-gcc-gnatbind

The suggestion from that would appear to be that your gtk may have
been built with a different version of GNAT, hence you might need to
recompile the GtkAda library with whatever version of GNAT you've now
got.

However, did you download the GtkAda version matching the GNAT
Community version from here - https://www.adacore.com/download/more?

Yesterday I downloaded and installed GtkAda and GNAT Studio again from 
the site you mentioned the error did not disappear.
In the mean time I tried to rebuild another project and it created a 
simular problem but with glib.ali
I read the stack overflow item but I think that is not the problem.
For reasons of tracebility I did not build GtkAda in the original 
directory but in C:/GNAT/GtkAda.
The last uodate of the OS was only a few days ago but after that it 
still worhed

The complaint about mismatched versions is almost certainly derived from
the version info in the first line of an ALI file.

Here I see (from a collection of old StackOverflow-related
investigations)

First line              Compiler
-----------------       ------------
V "GNAT Lib v10"        FSF GCC 10
V "GNAT Lib v11"        FSF GCC 11
V "GNAT Lib v2019"      GNAT CE 2019
V "GNAT Lib v2020"      GNAT CE 2020
V "GNAT Lib v7"         FSF GCC 7
V "GNAT Lib v8"         FSF GCC 8
V "GNAT Lib v9"         FSF GCC 9

Using a wrong ADA_PROJECT_PATH/GPR_PROJECT_PATH can lead to this. Using
gprbuild -v can help.

Also,

* Compile unit U with A.gpr which puts the ALI in directory A_OBJ
* Move unit U into the source tree for B.gpr which put the ALI in
  directory B_OBJ
* Run gprclean on A.gpr, which doesn't delete U.ali because U is no logner
  one of its sources
* Change compiler!

This are the values:
GPR_PROJECT_PATH=C:\GNAT\GtkADA\lib\gnat;D:\ada\project\template-parser
ADA_PROJECT_PATH=C:\GNAT\GtkADA\lib\gnat;.....
I think The Path és are the same, I am using GNAT  Studio Community 
version 2020 and all Gtk.ali are GNAT Lib v2020
gprbuild -v did not change anything. Changing the compiler is the worst 
thing I can do because I cannot find any straight forward method os 
installing like the mthod from Adacore

I meant, if you run those steps in that order and then use a different
compiler to rebuild your project, you'll have one of the old compiler's
ALIs where it shouldn't be, and if gnatbind sees it you'll end up with
mismatched compiler versions and no amount of gprclean will fix it.

On the other hand, you have been reinstalling and rebuilding ...

Sorry, no idea whether these are what they "should" be

But reading the output might show you what it did.

Also, gprbuild ... -bargs -v might show you what gnatbind thinks it's
doing.

No, not suggesting you should change, but this problem might be a result
of having changed in the past.

I finally found the problem I believe
Datum.ali build by V "GNAT Lib v9"        GPS Community version 2020
gtk.ali nuild by        V "GNAT Lib v2020" AdaCore Download

Both are dowmloaded feom the same page of AdaCore.
What is the best way to solve this?

How can I either install a GtkAda installarion which users the same 
compiler as the GPS community version 2020  on windows 10 wirh the same 
ease as the Adacore version or how can I if possible force the GOS 
compiler to accept the difference

You will have to compile the one using the wrong GNAT Lib version from source.

I had done so, but finally I decided to first delete Gtkada  and GPS and 
after first install GPS again and then Gtkada where I had to present the 
osition of the GPS position.

"GNAT Lib v9" is **not** generated by GNAT CE 2020.

I just tried on a 64-bit Windows virtual machine (the download was
gnat-2020-20200429-x86_64-windows-bin.exe, the shasum matches).

The ALI content is as I stated above,the same as your gtk.ali quoted
below.

Are you **100%** sure that the compiler you're running is the one you
think it is?

What does "gnatls -v" say? should be
