Cannot debug delphi code in the Python4Delphi Demo1 project - [Solved]

[JohnLM 24]

Specs:  Delphi XE7, VCL, Win7, Python4Delphi v3.8.10 (the last official build for windows 7) 

 

In one of my projects that includes P4D, I discovered that I can not debug the code.   Note, I am not debugging the Python aspects, just the Delphi code only, such as when you put a breakpoint at the line aString="ABCDEFG", as seen below.  Note also, that I am giving a simplified example, (where you see the breakpoint) just to show the issue. 

 

Note:  this is for any projects that include Python4Delphi. 

 

 

And the final result after pressing F9 (compile with debug). . . 

 

 

And, when I switch to 32-bit target and compile via F9, I get the following different issue: 

 

[dcc32 Fatal Error] Demo01.dpr(7): F2048 Bad unit format: 'Unit1.dcu' - Expected version: 28.0, Windows Unicode(x86) Found version: 28.0, Windows Unicode(x64)

 

I do not know how to resolve this.  I would like to do some debugging in my P4D projects but can't. 

 

Any advice would be greatly appreciated, thanks!

Delphi XE7 -- After some further investigation and research, it turns out that the debugger is not active in *any* 64-bit VCL and FMX applications.   I have the same error message shown in my first post, shown in the second image.  Only 32-bit apps have debugging working.   But the issue with the 32-bit debugging indicated in the previous post, 3rd example, is a separate issue with the P4D, I guess.

Another update. . . solved!!

 

Okay.  I believe I have resolved the issue with getting the debugger working in projects with Pytho4Delphi.   

 

My particular issue was with having a TFrame in the Python4Delphi project.  I had it as a 32-bit, while the main app was 64-bit.  And, when I changed both to 32-bit and recompiled via "Build-All Projects", then the debugger would work. If I had just only did a regular compile, the debugger would not work. 

 

Note, but still no debugger for 64-bit apps.  I did not know this was the case for XE7 because most my apps were 32-bit.  Oh well.
