Re: Making a portfile from a cmake based project

Thanks all that provided guidance.
I eventually disabled the tests build as they require downloading several
megs of audio files to be run, and check compliance to the r128 standard
rather than correct build of the library.

If both work, a path: dependency should be used to allow either.

If the project's developers provide a release download, it should be used. This 
project's developers don't, so it cannot be used here.

Variant names should not begin with words like "with" or "without" or "no". 

Does building the test suite really need to be a variant? How long does it take?

test.run yes

And change test.target if necessary.

I'm not sure if this is needed. I left it out in the experiment (and
as a consequence had to change the shasums).

No need to repeat name and version. They are set by github.setup already.

The maintainer audionuma would be a synonym for
audion...@macports.org. Since you probably don't have an account /
commit rights yet, you only need the second address and potentially
openmaintainer as well.

In this case you can use
long_description ${description}

No need. Both are set by github.setup already.

I was unable to use that because I already had "speex" installed. I
removed -devel and it seemed to work.

I'm not sure when this is needed.

The port certainly has to be fetched from somewhere.

I removed github.tarball_from and this is what I get:

OK.
Added a github.tarball_from releases command as there is a release on
github.
Nevertheless, I had to manually add the  libebur128-1.1.0.tar.gz file into
the /opt/local/var/macports/distfiles/libebur128 directory to have the
installation work, otherwise `port` was searching for the archive in it's
usual online repositories. Is that the expected behavior ?

Now, if I add the following lines to the Portfile (at the end)

variant with_tests description {Build tests suite} {
  configure.args-append -DENABLE_TESTS=ON
}

and run

port variants libebur128

the result is :

libebur128 has the variants:
   debug: Enable debug binaries
   universal: Build for multiple architectures

So it seems that my with_tests variant is not found.
I have tried a portindex command in the ~/ports directory with no success.

PortGroup   github 1.0
github.setupjiixyj libebur128 1.1.0 v

The first two arguments in github.setup are project name and
repository name, the third one is the version and the last one is the
prefix before the version (in the tag).

Then use "sudo port -v extract" to get the checksums (disclaimer:
until someone starts complaining that this is not a "safe enough"
approach because something could already be compromised).

PortGroup   cmake 1.0
# optional, but we would be grateful if you tested and included this
cmake.out_of_source yes

This is basically all you need. If you want to switch some features
on/off, you could do something like

configure.args-append -DENABLE_TESTS=ON

> I hope this beginner questions are not too obvious and that someone can
> point me to the adequate documentation for these questions.

You can take a look at cmake-1.0.tcl and github-1.0.tcl or grep for
cmake/github in other ports.

The rest is the same as for other ports.
