I did attempt to edit Jamie's script to handle xplanet and astrometry. I think I was mostly successful. The first time I tried to run the script though, it ran into some errors because the install_name_tool wouldn't work on either set of files due to file permissions. Once I changed the permissions on the items in the astrometry bin and xplanet bin folder in homebrew to 755, however, the script had no problem with that. Running the script on my new computer still causes the Capture Module crash on My wife's computer, but running the script on my old computer does not cause the crash. I still haven't solved that one.

After I ran the script on my old computer, I still had to copy libnova, libinidi, and libcfitsio to their correct locations. (This might have something to do with my old computer, I don't know) And when I tested xplanet, I found that it had given the wrong file path for the two dylib dependencies. I had to manually run:

install_name_tool -change @executable_path/../Frameworks/libjpeg.8.dylib @executable_path/../../../Frameworks/libjpeg.8.dylib /Users/rlancaste/Desktop/kstars.app/Contents/MacOS/xplanet/bin/libtiff.5.dylib
install_name_tool -change @executable_path/../Frameworks/libpng16.16.dylib @executable_path/../../../Frameworks/libpng16.16.dylib /Users/rlancaste/Desktop/kstars.app/Contents/MacOS/xplanet/bin/libfreetype.6.dylib

After, I made all of those changes, everything was mostly working great! So, I decided to run a couple of tests. I tried copying the GSC data folder to my wife's computer's kstars folder. It didn't work. I finally figured out that we need to copy the gsc executable into the Indi folder inside the app. It was no big deal after I figured it out. Since I now had fake stars on my wife's computer, I could run astrometry on them. I cannot test the offline solver on her computer yet since she has no python or pyfits. But it worked in the online solver. I also tested running an indiserver with simulators on my computer downstairs and connecting to it remotely from her computer. It worked great!

So, I made progress, but there are still some stumbling blocks. However, the good news is that I have a fully working latest-version KStars.app compiled just today with support for xplanet, Indi, and gsc. So now you can test with fake stars, or maybe even with real ones if you connect to a real Indi server running equipment--I haven't tested this yet. I will post about that next.

Here is the latest version of KStars, compiled and working with INDI and xplanet, and GSC support on OS X.

As I mentioned in my last post, I added gsc support to this app. All you need to do to get fake stars in the KStars CCD Simulator, is unzip the following file and put the gsc folder it contains into ~/Library/Application Support/kstars/. The zip file is about 240 MB, but it is worth it for testing purposes.

This version does not yet support the offline version of astrometry fully, since I haven't had time to solve that one yet. But online astrometry should work great.

So more good news. Apparently, the work I had done last night with Jamie's script to get the Astrometry files packaged up DID in fact work. There are just some unmet dependencies. In order to run, Astrometry also needs python, pyfits, and netpbm to be installed on the machine.

I found a nice installer for python that worked well without needing home-brew or anything to be installed on the machine from www.python.org/downloads/ : www.python.org/ftp/python/2.7.13/python-2.7.13-macosx10.6.pkg

After python is installed, all you need to do is run "pip install pyfits" from the Terminal and pyfits will get installed, no problem!

Then I found I still needed netpbm. I searched a little but could not find a nice installer for that. Perhaps a little more looking is in order. For now though this procedure: macappstore.org/netpbm/ worked:

ruby -e "$(curl -fsSL raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null
brew install netpbm

Of course running that installs home-brew and the OS X command line tools, which is something I would like to avoid to make things beginner friendly.... However, it worked perfectly!! I was able to plate solve images on my wife's computer using the Align Module and using the fake stars of gsc.

Note that Python is installed by default on OSX; it's used by the OS. On my El Capitan box, python was installed at /usr/bin/python, and is version 2.7.10.

For some reason, pip is not installed by default in the OSX version of Python; you can get pip at bootstrap.pypa.io/get-pip.py or you should be able to sudo easy_install pip

Oh ok, I assumed it was the lack of python in general, I guess it was just the lack of pyfits that was causing the problem. Thanks!

I just solved another problem!

For a long time I have been trying to figure out why the Image Downloader in the details window does not work, giving an error about not being able to find http in any .service files. I knew the issue was with the kde plugins for the internet downloads. I just didn't know why it was a problem. It turns out all we need to do is simply copy all the files from the directory ~/IndiRoot/kstars-emerge/lib/plugins to ~/IndiRoot/kstars-emerge/Applications/KDE/KStars.app/Contents/PlugIns/

I tried that and it just started working!

I will have to test it on my wife's computer though.

I tested it on my wife's computer and the image downloader did not work unfortunately, but I understand why and I have started trying to fix the problem. Running the emerge/craft made the KStars app hard linked with some of the programs and libraries in the INDIRoot folder. On my wife's computer this file structure does not exist of course. Because I didn't have the image downloader that uses the other KF5 programs working until just this evening, I didn't know they were not working properly on her computer. The issue is that we need to copy more than just the plugins folder. We also need the program kioslave, which of course will need to have the install_name_tool run on it. I did manage to do that manually and that part worked. And there are a couple of other programs and dylibs in the app bundle that still need to have the tool run on them too in order for the image downloads to work on her computer. Luckily I have Jamie's script for automation. I copied the section where he did the install name tool so that I could run it on folders/programs that need it run in a fast and automated way. But there are more I haven't done yet, so It will probably be at least another day till I have the image downloader working on a non-development computer.

I have been looking at this website, which is the script that Kate uses to finish up their Mac app. It is possible that, if we set the right flags and environment variables, the macdeployqt program could do some of the file copying and install_name_tool changes for us, since I believe that is largely what it is meant to do. github.com/KDE/kate/blob/master/mac/emerge-deploy.sh

I am working on getting these changes into Jamie's script as best I can. I hope Jamie gets well soon so he can check my work ;-). Through experimentation I found out that for the macdeployqt command, -executable does seem to work well (at least it seemed to do something for kioslave) and we might want to do some more with that. the -extra plugins command did nothing really, except break the deployment step because it did not recognize it. I ended up just copying the plugins and that worked fine.

I am actually traveling again, in Sweden this week.

Don't forget that you are listed as a contributor on the github repo - make a branch (not a fork) for your changes, and check them in! when you have it where you want it submit a pull request, and I will do some diffs and perhaps comment on enhancement.

I should be able to look at it next week :)

Ok, sounds good. Thanks Jamie. I will try to do so. I haven't done it before so we will see how it goes. I will probably do a little more work on it tonight before I try to post it.

So I worked out a bunch of issues in the last couple of days.

1. In trying to solve the issue with Image downloading from the details window, I explained before I had to copy the plugins. But while that worked on my computer, it did not work on my wife's computer. I found that the reason why was that they were pointing to libraries and files in the INDIRoot folder which was on my computer not hers. So I added those plugins to the list of files to be run through the Install_name_tool.

2. In exploring the problem above, I finally found out that it would be better to use @loader_path instead of @executable_path in that tool because Jamie's script determines the location of the dylib files from the file it is running the install_name_tool from, rather than the executable that is running that file. In other words, while the @executable_path works great for direct dependencies of executables, it doesn't work for the dependencies of dylibs. @loader_path would then use the path from the executable or the dylib, whichever called on the dependency. So I changed that in the script.

3. Then I discovered the reason why I was having trouble with libindi, libnova, and libcfitsio files being copied into the frameworks folder. Jamie's script was using this command to find them: filename=$(find /usr/local -name "${base}"). The problem is that it was returning multiple results, so when you tried to use the cp command, it didn't work because the string for the filename contained multiple files. So I modified it to take the first one it finds. We might want to change this later, and it may not be the correct way to do it, I don't know, but for now it seems to fix the problem. filename=$(echo $(find /usr/local -name "${base}")| cut -d" " -f1)

4. After that, I decided to try working on the dmg to make it pretty. So I used this website as a reference and modified our code at the end of the script to make a nice dmg. community.kde.org/Marble/MacPackaging

I now have a great working dmg that I built on my old Mac that should work perfectly on both newer and older Macs!

Note, that this was built with my old Mac running El Capitan. If I try to run Jamie's script on my new Mac, it also produces a dmg that mostly works great on both my new and old Mac and my wife's computer. But if I try to connect to an indiserver and take an exposure, it still says Illegal instruction:4. Which means something somewhere is not built properly for older versions of the OS I think. But regardless, we have great progress. A fully working dmg!

Here is a Screenshot of the dmg opened and ready for the KStars.app to be copied to the desktop or to the applications folder, or anywhere really. This app should be able to be copied wherever you want and run.



Here is a link to this dmg, which as far as I can tell works perfectly. drive.google.com/file/d/0B_ivMJINsdQ8SHp...cGc/view?usp=sharing

Remember though:
1. If you want to run plate solving, you will need to install pip, pyfits, and netpbm following the instructions I already gave you. Also you would need to copy astrometry index files into the ~/Library/Application Support/Astrometry/ folder.
2. If you want fake stars in the ccd simulator, you will need to download my gsc zip file and copy it into your ~/Library/Application Support/KStars/ folder.

We will probably want to next figure out exactly what we need to do to provide license and source code information for the various open source software inside to comply with the license agreements. Also figure out what causes the error I reported with the version I built with my new Mac.

I will post my changes to Jamie's script on the GIST in the next couple of hours after I figure out how to do that.
