I've just compiled version 1.10 (22nd of November 2008) of Win32-OpenACS: an actual native Win32 port (no Cygwin, no VMware) of OpenACS.

This version comes with a proper Windows Installer and contains .LRN 2.4.1!

This version of Win32-OpenACS consists of the following components:
1. aolserver-4.5.0 - including
1.1 nscache 1.4
1.2 nssha1 1.1.1.1
1.3 nspostgres 4.1
1.4 nsoracle 2.7
2. tcl-8.5.5
3. tk-8.5.5
4. tDom-0.8.2
5. xotcl-1.6.2
6. thread-2.6.5
7. tcllib-1.10
8. postgresql-8.2.11-1
9. openacs-5.5.x (CVS Head of the 27/10/2008)
10. xowiki-1.0.3
11. dotlrn-2.4.1

The port can be obtained at the following URL:

BTW: Merry Xmas and Happy New Year to everybody!

Hope it helps,
Maurizio

# nsthread library which should become standard in 5.3
if {[file exists ${homedir}/lib/thread2.6.4/libthread2.6.4[info sharedlibextension]]} {
ns_param libthread ${homedir}/lib/thread2.6.4/libthread2.6.4[info sharedlibextension]
}

There is no such folder. There is a thrad2.6.5 folder but there is no libthread2.6.5* file. There are thread26* files and there is a bin/nsthread* file.

Any idea?

However, your suggested approach with "package require Thread" does not work for aolserver. The existing code requires a version of libthread compiled as an aolserver module (under unix, configure with --with-aolserver=...; see http://openacs.org/xowiki/tag/libthread). When compiled this way, libthread names several commands differently and has a different initialization/cleanup behavior.

If possible, please provide libthread compiled as an aolserver module in the next release.
