Re: [TCLCORE] Pain points as a distro maintainer

[<apn...@ya...>]

Stu,

Does this mean you expect or plan for only one Tcl version to be installed on the system since the directories are not version-specific? Or that packages are expected to be built so as to be Tcl8 and 9 compatible, loading (in the case of binary extensions) the appropriate shared library (tclfoo.so vs tcl9foo.so)?

Extension home is /usr/local/lib/tcl.

A Tcl-only extension "foo" will be installed in /usr/local/lib/tcl/foo.
Preferentially, install Tcl-only extensions as Tcl Modules, if possible.

A binary loadable-only extension "foo" (ex. dbus) will be installed in /usr/local/lib/tcl/foo.

For a binary linkable-and-loadable extension "foo" (ex. tdbc),
the pkgIndex.tcl will be installed in /usr/local/lib/tcl/foo,
the .so in /usr/local/lib,
and any .h files in /usr/local/include.

Executables are installed in /usr/local/bin.

Stu,

That was very helpful for me to wrap my head around Unix installs.

One item that was left out (question for both Stu and Pietro) was where do
third party packages like tcllib, critcl etc. get installed? Note these
packages may have Tcl script libraries, shared libraries as well as
"applications" like critcl. Do they go into a common system directory or a
Tcl version-specific location?

Hi,

On OpenBSD:

My only real concern would be the Thread extension, which, if not made to
work in 8 and 9, would have to be separate extension: tclthread and
tcl9thread. Not great, not terrible.

Right now, everything 8/9 is as integrated as possible but separated where
necessary.

Tcl/Tk 8.5 and 8.6 are installed under dir names "8.5" and "8.6".

Tcl/Tk 9 will simply be "9". When 9.1 is released, it will replace 9.0.

The paths and dirs for 9 will be similar, but I'll be keeping the older
naming convention for libs and maybe other things, ie: libtk90.so instead of
libtcl9tk90.so.

These are the default auto_path and tm paths:
$ tclsh8.6
% set auto_path
/usr/local/lib/tcl/tcl8.6 /usr/local/lib/tcl
% tcl::tm::path list
/usr/local/lib/tcl/modules/85 /usr/local/lib/tcl/modules/86
/usr/local/lib/tcl/tcl8.6/modules

Here's the packing list for 8.6:
https://cvsweb.openbsd.org/cgi-bin/cvsweb/~checkout~/ports/lang/tcl/8.6/pkg/
PLIST?rev=1.17&content-type=text/plain

Here's a snip of the most important bits of the package readme:
