vigra: New port for VIGRA Image Library

[BSeppke (Benjamin Seppke)]

Some more information about this wonderful c++ image processing lib:

VIGRA stands for "Vision with Generic Algorithms". It's a novel computer vision library that puts its main emphasize on customizable algorithms and data structures. By using template techniques similar to those in the C++ Standard Template Library, you can easily adapt any VIGRA component to the needs of your application, without thereby giving up execution speed.

The Portfile of the new port for vigra

[ryandesign (Ryan Carsten Schmidt)]

I committed the port in r38306 with these changes:

• Fixed install command parameter (-m not --mode=) so it works with Apple's BSD install too, not just GNU install.
• Fixed destroot phase so port actually installs into destroot and MacPorts can track the port's contents.
• Fixed documentation installation so it goes where MacPorts documentation customarily lives.
• Fixed livecheck so it works.
• Enabled parallel build to speed things up for users with multiple processors and/or multiple processor cores.
• Indicate that the universal variant does not work.
• Escaped the quotes in the long description so the port is considered syntactically valid.
• Fixed a typo in the long description. (emphasize => emphasis)
• Changed master_sites to use the ${homepage} variable instead of repeating the homepage URL.
• Changed distname to use the ${name} variable instead of repeating the port name.
• Removed --prefix=${prefix} --exec-prefix=${prefix} from configure.args since --prefix=${prefix} is already in configure.pre_args and --exec-prefix=${prefix} should be the default when --prefix=${prefix} is used.
• Switched from a mix of tabs and spaces for indentation to all spaces, and removed trailing whitespace.

You set the maintainer to nomaintainer. I set it to myself and openmaintainer, but I don't really know the software. Would you like to be the maintainer?

[BSeppke (Benjamin Seppke)]

Yes, I would like to be the maintainer. I'm relatively new to MacPorts, so I'm sorry for the work you had with this port. Thanks a lot for cleaning up!

[BSeppke (Benjamin Seppke)]

I tried out the now available port, but without success - unfortunately... It seems, that there are no bindings to the needed libraries inside the libvigraimpex.dylib (to libpng, libz, libjpeg and libtiff). Normally, the configure searches them, and should find them in /opt/local/(lib). If all are found, the vigra-config command should also return them when calling vigra-config --libs. This is not the case after installing this port, so my explanation to this is that they're just not found by the configure. How can I test (and of course fix) that behaviour?

[ryandesign (Ryan Carsten Schmidt)]

Sorry, I overlooked your note until now.

I updated the vigra port to 1.6.0 in r39268.

I agree vigra-config --libs doesn't show any links to the other libraries, and otool -L /opt/local/lib/libvigraimpex.2.0.160.dylib doesn't show the library linking with those other libraries.

You can sudo port -d configure vigra and look at all the output produced. You can also examine the file config.log in the source directory after configure is run.

[ryandesign (Ryan Carsten Schmidt)]

I made you the maintainer in r39269.

Fixed in r39270. Apparently the --with-foo=dir form doesn't work so well (should probably report that problem upstream), but --with-foo works fine.
