Hi,DLLs are executables thus they need the +x bit. This is a Windows thing.
When I type "cyg" and Tab, many executables starting with "cyg" are listed
(Display all 262 possibilities? (y or n) y). I find that many of them are
*.dll libraries under /usr/bin/. This is inconvenient to find the real
executable applications (*.exe). Since *.dll files are only libraries, they
are not necessary to have the attribute of "x". Thus, I run the command
"chmod a-x /usr/bin/*.dll". Unexpectedly, cygwin is corrupted. I closed the
terminal and failed to restart Cygwin. I started my older version of Cygwin
(I did not deleted it after installing a new version), and added "x" to the
previous *.dll files. The dead Cygwin revived.
I am confused why /usr/bin/*.dll should be executable. I thought they were
only library files. When I tried to run a dll file, bash says "cannot
execute binary file". Are there some hidden stories?
If this is a windows thing, removing the x bit should not affect Cygwin.
Instead, Cygwin is corrupted after removing the x bit.
