The most likely reason and the solution for it were already provided to you by
Cygwin itself.  See above.  Have you read and performed those instructions?

===========================================

Yes, we have read and performed those instruction. We have placed the
cygwin1.dll in current working folder which is inside the
c:\cygwin\bin folder while generating  the exe. We have checked the
size of the dll also. Both are same size .
Then wt are the possible reasons for this problem??

I must be missing some critical detail in your description.  Are you talking 
about two different machines, building an EXE on one and then running it on 
another?  What do you mean by "placing cygwin1.dll in the current working 
folder"?

There can be only one cygwin1.dll on the machine, put where it's supposed to be 
by using the Cygwin setup.exe.  You can't just put another copy of cygwin1.dll 
somewhere else on that machine.

Yes, you can.

Dynamic-Link library search order
   A system can contain multiple versions of the same dynamic-link
library (DLL).


That said .. wasn't there something recently on this list about not
being able to find cygwin1.dll using the windows search?  Probably
either attrib or dir from a command prompt would find it - eg:

C:\>attrib cygwin1.dll /s
           C:\Cygwin\bin\cygwin1.dll
           C:\Cygwin\source\tcptrace\cygwin-libs\win9x\cygwin1.dll
           C:\Cygwin\source\tcptrace\cygwin-libs\winNT\cygwin1.dll
           C:\Cygwin\source\tcptrace\cygwin-libs\cygwin1.dll
           C:\MyProgs\John\run\cygwin1.dll
           C:\MyProgs\TCPtrace\cygwin1.dll
           C:\MyProgs\win_xplot\bin\win9x\cygwin1.dll
           C:\MyProgs\win_xplot\bin\winNT\cygwin1.dll

...if you know what you're doing.  If you don't, keep only the one that
'setup.exe' installs and keep it where it installed it.  Doing anything
else assumes that you know what you're doing and that you don't have to
query this list when something goes wrong.  That's why we recommend to
folks that inquire to keep one copy only.  Any other configuration is
unsupported by this list due to the complexities it introduces.

The fact that you *can* do this doesn't mean that it is a good practice
to do this.  In fact, the error message that started out this thread
clearly showed that there are problems.

We tend to offer unequivocal advice to confused end users who don't
exactly know what they are doing since it is bad practice to advise them
to play with multiple versions of cygwin.  Most of the time they have a
copy on their system that they don't know about and are better off
deleting it.

Trying to instruct someone in the rules involved in dll searches is
not really a fruitful endeavor in the long run.

So, what I'm saying is that go ahead and pat yourself on the back for
figuring out how to use multiple versions of cygwin.  It is still a bad
idea and should not be encouraged for the normal user.

True for DLLs in general - false for cygwin1.dll. Read

You have misunderstood the problem.  It has nothing to do with
incompatibilities between the dll used to build an exe and to run it.
The problem is having multiple versions of the dll running on the same
machine at the same time.  Please re-read cygwin's advice with this
in mind.

Ugrent !! Reg. Executing the EXE generated by Cygwin

[Mani kandan]

Hi,

We have built an exe in cygwin which calls a .bat file which inturn
invokes another cygwin generate exe.
When we run exe in Windows 2003 Server, we get the following error.

 69750 [main] ? (5536) C:\cygwin\bin\sh.exe: *** fatal error - cygheap base mis
match detected - 0x9F88E0/0x611688E0.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version.  The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution.  Rebooting is also suggested if you
are unable to find another cygwin DLL.

We have made sure that we use the same version of cygwin1.dll while
building the exe and while running it on the server.
What are the possible reasons for this? Are there any other solutions to this?

Regards
Mani

The most likely reason and the solution for it were already provided to you by 
Cygwin itself.  See above.  Have you read and performed those instructions?
