Hi David

The issue you describe arises because the CDL library, on which the eCos
host tools are based, uses Tcl to read/write files. Tcl uses its own
line-ending translation layer and ignores the Cygwin filesystem mount
mode (text or binary). This is one of the reasons why I always recommend
the use of a filesystem mounted in text mode for eCos development on
Microsoft Windows.

While it would certainly be possible to hack the eCos tools to
workaround this issue, the correct location for a fix would be in the
Tcl library.

John,
I don't know if this is the right time to bring this up. But it is a
minor "windows" issue that we came across.
We use subversion for our VCS system. When we configured it to use
native line-endings (I don't remember the correct term for that in svn
lingo), we found the ecosconfig spits out files with Windows line
endings under windows/cygwin, even if cygwin is configured for unix
line-endings. This caused cygwin's svn to think that our ecosconfig
file changed every time we ran 'ecosconfig anything'.

Our solution was to use a windows native svn client.  One developer
used TortiseSVN. I downloaded the windows command line version from
tigris.org. Both of these used windows line endings for everything, so
it matched ecosconfig.

But it would be nice if ecosconfig would honor the cygwin setting, or
maybe have a command line option for one or the other. Or if there is
an existing file, keep the line endings the same.

The native Tcl DLL filename is the same as that of the Cygwin Tcl DLL.
In my opinion, the Cygwin Tcl/Tk package should use a different DLL name
such as cygtcl84.dll. I will look into the possibility of at least
warning users about this problem as you suggest. Of course, you can
arrange for the Cygwin /bin directory to be ahead of C:\Tcl\bin in your
PATH when you invoke the eCos Configuration Tool, but it will not be
possible to use an application which requires the ActiveTcl tcl84.dll at
the same time as a tool which requires the Cygwin tcl84.dll.

The default install folder for ActiceTcl (8.4) is C:\Tcl (likely more
accurately <SystemDrive>:\Tcl. The DLL is named tcl84.dll and is located
under the C:\Tcl\bin folder.

Alternatively, I notice that they also set a TCLHOME environment
variable, which points to the root of the install. Or, in the Registry,
there is an HKEY_CLASSES_ROOT\ActiveTclScript key, which may be scanned
for the install location.

Thanks for the feedback. What is the filename of the ActiveTcl DLL and
where is it installed by default?

Yes, I understand that now. Initially, I was approaching the tool as a
Windows user, with certain assumptions.

Part of the confusion on my part was that the configtool would give an
error when reading the ecos.db file, which gave no clue as to why it
might be failing. Perhaps a Tcl version/platform check ought to be done
in the application.

Native builds Tcl/Tk for Windows know nothing about cygwin environment
and cygwin paths, so, they won't be able execs cygwin's binaries and
toolchains in a native maner without dances.

cygwin/mingw/uwin/sfu(interix) use own emulations of Unix environment,
so they all use own Tcl/Tk builds.

FYI, I have used this experimental build on Vista without any issues. I
also used the previous version without incident as well though.

One item that did hang me up for a while though was that the Windows
configtool is NOT compatible with the Windows Tcl (I used ActiveTcl from
ActiveState). You have to use the Tcl that is installed along with
cygwin. For some reason this was not clear to me. I would think other
Windows users may get bitten here too.

Thank you,
