Sorry, I was half wrong: on windows 7 - 32 bits it works.

The problem happens only on W2008R2 (64 bits) with cygwin 32 binaries.

For example, when launching only bash.exe as a service, bash EXITS immediately.

But, If I launch bash.exe  and then another win32bit executable (ex:
msys sh.exe), then OIUDetect is "captured" and bash.exe doesn't exit.

So "it seems that 32 bits cygwin are not correctly managed on 64 bits systems"

No, this is not the question: uiodetect is always started.

Could you help me?

Thanks a lot for your time.

Hello,

I attach here my tests to clarify:

#Test1 - Only bash
C:\cywin\bin\bash.exe

Result: bash exits. Interactive window not opened.

#Test2 - Two programs
C:\cywin\bin\bash.exe
"%WD%..\BGBINARIES\Window\Window.exe"

Result: Interactive window opened: you can find only Window.exe opened.

#Test3 - Bash started via "start"
start "test" C:\cywin\bin\bash.exe
"%WD%..\BGBINARIES\Window\Window.exe"

Result: Interactive window opened: you can find both programs opened.

Conclusions:
1- What opens the interactive window is a program that doesn't exit.
2- bash.exe never opens the interactive window because it exits,or it
doesn't exit if it is launched with the start command(test3).
3- bash.exe launched with start command is started (test3), but the
interactive window is opened due to Window.exe (that doesn't exit).

Thanks a lot for your time.

Yes, you know this now but this was the question you were asking in the
last round.  Fortunately, you do not need my answer now. :-)

You're invoking bash non-interactively.  Since you want an interactive
shell, you should be using the '-i' flag.

Hello, -i flag is used on W7 as in W2008 R2.

interactive-services-detection not started on 32-bit cywin executables

[BGINFO4X]

Hello everybody,

I have a "Windows service implementation of cygwin" via NSSM
(http://nssm.cc/). I use cygwin 1.7.27 32 bits.

If I configure the service as "allow service to interact with
desktop", the UIODETEC.exe is not started, so I can't see the console.

Do you know why uiodetect is not started with 32-bit cygwin
executables? Any workaround? I tested it on W2008 R2 (64 bits) and W7
32 bits.

Note: If I use msys binaries, the console is shown.

You can find more information about uiodetect here:

Thanks a lot for your time.

The only workaround I can think of is to start the uiodetect service.

And now trying it with a simple test (the one suggested at your link below)
it worked for me if the window in which the shell runs is running as
administrator.  Did you try that?
