The error occurs after I downloaded the FLTK source tar archive with Firefox, unfold the archive
and build FLTK. The error symptom is a popup window saying
"Blocks is damaged and can't be opened.
Firefox downloaded this file on …"

If I git clone, git checkout branch-1.3 and build with configure : NO ERROR!

Yes, I see this too.

If I copy the blocks.app dir from my CMake-based build, _empty it completely_, and then fill it with the content of blocks.app from my firefox+configure build : NO ERROR Thus, the difference in Info.plist between CMake and configure builds is not the culprit.

I made a similar test: in the <firefox-download> folder I removed test/blocks.app/Contents/MacOS and Info.plist, then replaced Info.plist with the Git version and built again (after also removing the blocks wrapper script). After these steps I could open blocks.app with the Finder.

Thus , the status "I'm suspect, I was downloaded from internet" seems transferred from the tar archive all the way to the blocks.app directory and to block launching these 3 apps.

To circumvent this "security problem" I moved blocks.app aside and created it again manually. I used an editor (code => VS Code) to edit the files to avoid duplicating any "downloaded from internet" attributes, wherever they may be hidden.

See attached file modify_blocks_app.txt for what I did. This worked as intended, now blocks.app can be opened with the finder and with 'open test/blocks.app'.

Finally I recreated the entire directory structure of checkers.app and just /copied/ everything from the saved structure, see attached modify_checkers.txt, and this worked as well. This is more or less what you described but I tried it so we can maybe use it in an automated way to get rid of the problem.

That's real SECURITY! Move unsecure files away, copy the contents back, and then it's secure. ;-)
Apple???
