Hi,=20
=20
Take a look at "README.FIRST" included in the distribution:
=20
"The programs in omniORB3 are distributed under the GNU
General Public Licence as published by the Free Software Foundation.
See the file COPYING for copying permission of these programs. The
libraries in omniORB3 are distributed under the GNU Library General
Public Licence. See the file COPYING.LIB for copying permission of
these libraries."
=20
Ergo, the omniThreads and omniORB libraries are LGPLed, allowing you to =
to use them in closed source products. The LGPL requires you to make =
available upon request the source code to these libraries. If you point =
to the omniORB website in your documentation, I expect interested users =
to grab the latest source there instead of requesting it from you. =
Anyway it's a small effort.
And you'll want to dynamically link to the omniORB code indeed. If you =
desperately need to statically link, you'll have to negotiate a =
commercial license with the omniORB copyright holders. Most likely =
Duncan will be able to tell you whether AT&T is the sole copyright =
holder or there are others as well.

the LGPL.

Subject: [omniORB] OmniOrb and OmniThread licensing
Hi,=20
we wish to explore building and commercially distributing software with =
OmniOrb and OmniThreads. Quoting =
http://www.uk.research.att.com/omniORB/omniORBWhy.html:
"We encourage you to use it, port it, fix bugs in it, extend and =
generally improve it. We simply require that this is done under the =
terms and conditions of the GNU General Public License < =
http://www.fsf.org/copyleft/gpl.html> and GNU Library General Public =
License < http://www.fsf.org/copyleft/lgpl.html>. "
GPL and LGPL? We believe they are incompatible, so this is odd. Can we =
interpret this as LGPL for the libraries we link against? We understand =
however that this would still require us to distribute complete sources =
and (realistically) precludes us from static linking against it.
Is our understanding correct?=20
