tools/mksymtab.sh does not work properly in Windows MSYS about nuttx-apps

[patacongo]

Details of the behaviors differ with file system and are not the same for Cygwin and MSYS2:

Cygwin on NTFS:

$ touch testfile

$ ls -l testfile
-rwxrw-r--+ 1 spuda spuda 0 Sep 30 09:10 testfile

$ chmod +x testfile

$ ls -l testfile
-rwxrwxr-x+ 1 spuda spuda 0 Sep 30 09:10 testfile

MSYS2 on NTFS:

$ ls -l testfile
-rw-r--r-- 1 spuda spuda 0 Sep 30 09:10 testfile

$ rm testfile

$ touch anotherfile

$ ls -l anotherfile
-rw-r--r-- 1 spuda spuda 0 Sep 30 09:16 anotherfile

$ chmod +x anotherfile

$ ls -l anotherfile
-rw-r--r-- 1 spuda spuda 0 Sep 30 09:16 anotherfile

@baggio63446333 do you know MSYS fail to run "chmod +x"?

This is a property of Windows file systems: Windows file systems do not retain a executable bit. In Cygwin (and MSYS which is a Cygwin variant), this property is determined by the file extension. If the file ends in .exe, for example, the file will be reported as executable. See https://cygwin.com/cygwin-ug-net/using-filemodes.html

Interesting but off-topic: There are instructions for setting up MSYS2 in github CI here: https://www.msys2.org/docs/ci/
