Question about packaging and cygport

Question about packaging and cygport

[Arjen Markus]

Hello,

In the context of the PLplot project (plplot.sf.net) we are interested
in the details of how software is packaged for Cygwin, in particular
how CMake is packaged (development of this package is rather fast and
we attempt to keep up with it, so that we can clean up the various
workarounds).

To better understand the process, we would like to know, how packaging
is arranged - is that via "cygport" files? And if so, what is the
authorative location of these files (notably cmake.cygport)? If some
other method is used, could you enllighten us about the actual
process?

Regards,

Arjen

.cygport file is an instruction about assembling (and publishing) Cygwin
package.
Why do you need to package cmake ? If not, what cmake.cygport does in your
question?

Cygport provides a way for maintainers to build packages that are
compatible with the Cygwin package distribution tools, so most
maintainers use it, but I think there are still a few packages that
are maintained without cygport; provided maintainers upload packages
that are compatible with the package distribution tools used by the
Cygwin project, maintainers are free to use whatever tools they like.
In the specific case of cmake, that package does use cygport, but it's
not guaranteed that all packages will.

The only authoritative source of these files will be the source
package downloads you can get through the Cygwin installer, by ticking
the "Src?" box in the setup-(x86|x86_64).exe installer. Those are only
guaranteed to include the source code itself, but for any package
using cygport, you can expect they'll also include the cygport file
and any associated files. There's no general repository for the
packaging tools and configuration other than that which maintainers
have uploaded to provide via the packaging distribution mirrors. Some
maintainers will keep their cygport files on GitHub or similar (I do),
but that's entirely down to the preferences of the individual
maintainer, and I don't know where – or even if – the cmake cygport
files are available anywhere else.

Ah, thanks a lot - I will pass on this information to my
co-maintainer. I did find
https://github.com/tkelman/cygwin-cmake/blob/master/cmake.cygport but
I do not know what its status is or even if it has any ;).

?

Pick a Cygwin mirror

 - https://cygwin.com/mirrors.html

e.g. "Twente" and select cmake (the pkg we are talking about):

 - http://ftp.snt.utwente.nl/pub/software/cygwin/x86_64/release/cmake/

Look for the tarrballs that terminate w/ -src.tar.xz. If the package has
a .cygport file, you will find it in the source tarballs.

I am uploading the cmake 3.14.5 package for cygwin
If you have problem in building in building plplot let me know.

Oops, Gmail is hiding the original mail from me under three dots. I
will try and keep this in mind. (It also persists in showing a name it
picked up at one point with the cygwin mail address and I have no idea
how or even if I can correct that. It may only be on my side of the
mail communication.)

As for CMake: I will let you know.

Re: Question about packaging and cygport

Hi Marco,

I just tried building PLplot with CMake 3.14.5 and got this error message:

-- OCTAVE_VERSION = 4.2.2
-- OCTAVE_LIBRARIES = /usr/lib/octave/4.2.2/liboctave.dll.a
-- OCTINTERP_LIBRARIES = /usr/lib/octave/4.2.2/liboctinterp.dll.a
-- OCTAVE_INCLUDE_PATH =
/usr/include;/usr/include/octave-4.2.2;/usr/include/octave-4.2.2/octave
-- Start determining consistent system data for Tcl and friends
CMake Error at /usr/share/cmake-3.14.5/Modules/FindTclsh.cmake:93:
  Parse error.  Expected a command name, got unterminated bracket with text
  ".rst:

Looking at some other "Find*.cmake" files I guess this line is missing:

Yes, after adding this line, it all worked fine.

this line is present at line 4 of the file.
Have you by chance modified it ?

No, the line I posted appears to be the closing line for the
comment/documentation. It is present in other such files, but was not
in the copy in my installation.

I noticed that an earlier version, directly from the CMake download,
had an extra comment there, specific to Cygwin:

#[=======================================================================[.rst:
FindTclsh
---------

Find tclsh

This module finds if TCL is installed and determines where the include
files and libraries are.  It also determines what the name of the
library is.  This code sets the following variables:

::

  TCLSH_FOUND = TRUE if tclsh has been found
  TCL_TCLSH = the path to the tclsh executable

In cygwin, look for the cygwin version first.  Don't look for it later
to avoid finding the cygwin version on a Win32 build.
#]=======================================================================]

if(CYGWIN)
  find_program(TCL_TCLSH NAMES cygtclsh83 cygtclsh80)
endif()

Regards,

Arjen

No, you are addressing - Andrey Repin <cygwin@cygwin.com> - you can fix that in
your Gmail address book in the Contacts list:

Thank you - I had no idea how to correct that, but with that link it
was relatively easy ;).
