Hi,
Maybe it has been covered somewhere -- I could not find the answer, so please
excuse the repetition. I observe that if I build an app (consider the simplest
"Hello world" program below as an example), and store the executable at a
standalone
location (not CYGWIN tree), yet supplemented it with a cygwin1.dll, it can then
successfully
run when started in the Windows shell (CMD.EXE) from a subdirectory, but fails
ungracefully
if run from the root of a drive (e.g. when stored onto a USB stick that has the
"flat"
file structure, w/o subdirectories).
Can anything be done about it? (Like allowing the app to run, or issuing an
error
saying "move me to a subdirectory" -- if there are principal problems of not
being able
to launch from the root directory. The same "friendlier" manner than Windows
warns
that it cannot run "a.exe" because "cygwin1.dll" is missing -- like in the case
when
the DLL was not copied to the "subdir" along with the executable.)
Thanks!
