splinter - a spline interpolation library

[repagh (Rene van Paassen)]

New port for a spline interpolation library.

Portfile

[repagh (Rene van Paassen)]

patch to fix install location matlab and python support files

[mf2k (Frank Schima)]

Comments:

• Can openmaintainer be added?
• You are overwriting the dependencies included with the cmake Portgroup. Replace, for example, depends_build with depends_build-append
• Use the GitHub portgroup to simplify the Portfile

diff file for using eigen3 port

[repagh (Rene van Paassen)]

Updated portfile

[repagh (Rene van Paassen)]

Thanks for the comments. I had a further look, and used the comments to (hopefully improve) the portfile

• openmaintainer added
• I could remove the depends_build dependency
• Now using the eigen3 port instead of the eigen3 supplied with splinter. The added patch fixes a coding issue with newer eigen3 and modifies the CMakeLists.txt file to not install the eigen3 headers
• using github portgroup now

I see a checksum failure:

Also, please see #47197 and verify if adding the following works:

cmake.out_of_source yes

Here is my modified Portfile. Please use this one.

[repagh (Rene van Paassen)]

Further updates to portfile

[repagh (Rene van Paassen)]

updated patch; fixes generation of version files

[repagh (Rene van Paassen)]

• fixed out-of-source build
• updated checksums (were probably wrong from a copy&paste error??), new patch-splinter-mlpyinstall.diff

[mf2k (Frank Schima)]

Hmmm. I still get a checksum error.

[repagh (Rene van Paassen)]

Huh?

I am getting the same error if I remove the splinter-3.0.zip that I had in my files section.

That splinter-3.0.zip was downloaded through the github web interface. I used it to check how to build splinter and develop the portfile. It is a real zip file, and has rmd160=d2dce503fbb8c89b4a17a912ce689e98dcdddefe

The splinter-3.0.zip that macports downloads is *not* a zip file. It has rmd160=4371f8e8617081b2e71d3a14181b522293b97493. The file cannot be unpacked through unzip, and is actually a tar.gz file, I successfully unpacked it by running it through gzip and tar. Its top directory is bgrimstad-splinter-2c877c0 and the contents are identical to those of the real zip file.

This is really confusing me now. Am I doing something wrong in the portfile? Does this happen only on the splinter project, or is it something common? I had expected to get the zip file through the github portgroup, but am getting a tar.gz, and with the wrong main dir to boot.

Or does the github portgroup only download tarballs, and do I only get the wrong extension with the use_zip option? That looks to me like a bug.

[repagh (Rene van Paassen)]

again updated portfile

[repagh (Rene van Paassen)]

OK. Apparently it is not possible to download .zip files with the github portgroup. Changed to use tar.gz (removed the use_zip) and corrected checksums

[mf2k (Frank Schima)]

It apparently has python bindings. I'm wondering is we need to either add variants for python 3.6 and python 2.7 or make this more like a python module and have it be named pyXY-splinter (e.g. py36-splinter) instead. There probably needs to at least be a runtime dependency on python. Thoughts?

Can the homepage be changed to something like ​https://splinter.readthedocs.io/en/latest/# ?

[mf2k (Frank Schima)]

I see now that there are two different packages on Github called splinter. This is not the python one.

[mf2k (Frank Schima)]

This project does have a python interface and we should address that in the Portfile by either automatically building it, and depending on python 3.6, or at least adding a variant for it.
