Re: [xml-cppdom-devel] [ggt-devel] Versioned directories on Windows

[subatomic <ke...@su...>]

totally agree...
and, if you need to change names on anything, do it on the filename...
i.e.
cppdom-1.4.5.dll
cppdomD-1.4.5.dll

but keep it in the local directory...
having these global stores (first the registry, now the dll database in
windows) seems prone to errors, or if nothing else, really inconvenient and
like you say, different than any other platform.


Are there issues with two running apps accessing the same name of dll (but
in different folders)??
If so, you may want to do the naming thing I mentioned above...
Otherwise, why add the complication....
