Solved-Switching to external mode

[cousinp]

Here is the message I can't remedy while trying to compile and run a simple 'Hello World' check box on a form. There is nothing else in the form or the unit, it was all presented by the Lazarus IDE. Attached under the Lazarus error message is my dir. structure and a partial list of the files in the  x86_64-win64  directory. The file Lazarus says they can't access is listed.
I am running Windows 10. Any help is much appreciated as always.

Do other projects build or just this one refuses to?
Did Lazarus start to misbehave just now? Did you make a fresh install?
What version of Lazarus do you use? Did you try to pause your antivirus, if you have one (or more)?

This is the first exercise I am doing with the IDE as I read through and follow the book.
I am using a clean install, this is the first use of the IDE.
I am using Lazarus 3.2.2, but the IDE says  Lazarus IDE v 3.4  at the top.
As soon as I saw you ask if I paused my antivirus the light went off.  I have to do that when compiling in the command prompt. I turned it off and the Lazarus IDE compiled with no problems.

CM630 you ARE a hero. Many Many thanks for your response.

So welcome to the world of Lazarus!
After you have found a solution, it is a good idea to rename the thread, adding “[SOLVED]” in its beginning.

I am using Lazarus 3.2.2, but the IDE says  Lazarus IDE v 3.4  at the top.

Most likely you are using FPC 3.2.2 and Lazarus IDE 3.4. FPC is the compiler, Lazarus is the editor, they are bundled, but they are actually two different things which work together.

As soon as I saw you ask if I paused my antivirus the light went off.  I have to do that when compiling in the command prompt. I turned it off and the Lazarus IDE compiled with no problems.

Maybe you should report this issue to the AV developers, if possible.
