I. Building the Tcl thread extension for Unix
=============================================
Extension can be compiled on several Unix derivates including various
distributions of Linux. Build process is pretty straightforward. I've
checked some versions of Solaris, Linux and Darwin, but the extension
should compile without problems on any Unix-like operating system
with a proper pthreads library implementation.
To build on Unix-like operating systems, start with the CONFIG script
and see if there is already a combination of the "configure" options
which may satisfy your needs. If not, you can run the configure script
located in the root of the distribution directory with a choice of
supported options yourself. If yes, you can uncomment corresponding
lines from the CONFIG script and do:
% sh CONFIG
Either way, this will create a Makefile which you use to run "make" and
"make install".
You can use "make clean" to clean the directory from temporary compilation
files and/or "make distclean" to additionaly remove local config files.
You might want to do "make test" before doing the "make install" in order
to run the regression tests on the package.
To explore other building options, look into the CONFIG file for more
information.
Note for NaviServer/AOLserver users
------------------------
The extension can be compiled as a loadable module for the
NaviServer/AOLserver version 4.0 or higher. In order to do this,
use "--with-naviserver" configure option to specify the directory
containing the NaviServer/AOLserver distribution. The CONFIG script
has an example how to invoke configure in order to build the
extension as NaviServer/AOLserver module. Note, however, that
"make install" and "make test" targets are still not supported for
NaviServer/AOLserver builds. This will be corrected in one of
the future releases.
To fine-tune, you might also want to make the tsv::* commands replace
the NaviServer/AOLserver built-in nsv_* family of commands, since
they are API compatible and provide richer command set plus advanced
shared-object storage of shared data. Go to the generic/threadSvCmd.h
file and look at the beginning of the file for the:
/* #define NSV_COMPAT 1 */
So, uncomment the line, recompile and there you go.
II. Building optional support libraries
=======================================
As of 2.6 release, this extension supports persistent shared variables.
To use this functionality, you might need to download and compile some
other supporting libraries. Currently, there is a simple implementation
of shared variable persistency built atop of popular GNU Gdbm package.
You can obtain the latest version of the Gdbm package from the GNU
website at: http://www.gnu.org/software/gdbm/gdbm.html
To compile with GNU Gdbm support you must configure with --with-gdbm
switch. This option, if used, will try to locate the Gdbm library on
your system at couple of standard locations. You might override this
behaviour by giving --with-gdbm=/some/dir. Note that both library file
and the include file must then reside in this directory.
