[ace-users] [Fwd: Unable to run simple ACE programs in cygwin]

[Adam Mitz]

Hi Ananth,

I'll first echo Johnny's statements about "official" support for Cygwin. 
  Patches from users are always apprciated, or you could fund your 
choice of commercial support company 
(http://www.cs.wustl.edu/~schmidt/commercial-support.html) to do this work.

That being said, I've seen error 128 on Windows when it can't find the 
DLL to load when the process starts.  You may want to check your PATH 
settings.

Thanks,

Hi,

I am running a simple client and server ACE programs on cygwin.
Compilation does not give any error. No error is shown at runtime
also, but it does not seem to run either. When I run the server, it
exits immediately. it does not block on 'accept' . 'echo $?' on the
shell shows return code as 128. Here are the things I tried:

1. 'ps -ef | grep <server / client>' does not show anything.
2. I ran make on the 'inserver' and 'inclient' programs in the
'examples' directory, ran the server and client, that also did not
give any result (and 'ps -ef' did not show any result here too).
3. I put in a couple of 'printf' at the beginning of 'main', this too
did not get printed at run-time. But commenting out all code except
the 'printf' worked.

Can someone please help?

I am compiling the code using this command:
g++ <server / client program name> -I/cygdrive/c/cygwin/ACE_wrappers/ /
cygdrive/c/cygwin/ACE_wrappers/ace/libACE.dll.a

Other details:

ACE version is 5.5.9.
