exported variables from dll

[Philippe GIACINTI]

Hi,

First off, I am new in the list, I'm working with Cygwin32 b18 since a couple
of weeks and I think it's really a great job ...

I have to port an Unix application which is based on plugins and shared
libraries on Windows NT 4.0, and I have some troubles with dll:

I wish to define some variables in a dll and use them in another, on Unix I
have no problems: the variable is defined global in one .cc and extern in
another.
If I use the same code in Cygwin32, it seems that each dll have a local copy of
this variable ( ie: the addresses are different ).
I tried to do this with VisualC++, and it works if I use the directive
DllImport instead of extern.

( in fact I have this problem in a dll which uses stdout, I found that
"_impure_ptr" was correctly initialized in main, but was null in the dll )

I'm really new in Cygwin32 and Windows environment, and I think (hope) it comes
from my ignorance.

Thanks for your help.
