IMO, this solution will work, but is not the best one. An installer that allows 
the user to select the installation directory (which is then fixed) is a better 
idea.

I don't move apps around very much, and I can't think of any time I've moved 
one after having the installer ask me where to install it (the ones I can 
remember moving are TeXLive, which installs its apps in some subsubfolder, and 
old iWork, when the same thing happened).

I'm not a fan of /Applications/sagemath-$version, as then upgrading causes a 
new folder to be made, which will break any aliases/dock shortcuts.

 Perhaps you should explain the steps that you did to get this far with 
 building Sage, such that other people can continue from there.

My method isn't easily reproducible.

Now, one can in theory install the dev tools by trying to run make. OS X should 
then ask you to download and install them (much like it does with X11). 
Alternatively (this is what will go in the readme), one can run the command 
xcode-select --install and click install in the resulting pop-up. (#15319). 
The other way is to log in to developer.apple.com and find the download.

 Dear all,

 It has been previously stated that the Command line tools of Xcode were 
 sufficient and could be downloaded separately form Apple dev site, but it 
 does not seem to be the case anymore (I've registered there, there's only 
 Java stuff and old Xcode 3.*).
That's odd. My Apple Dev thing (free version) looks like 
http://yomcat.geek.nz/sage/clt.PNG (that's just logging in at

 First it seems xcode is now free, cannot really check as I have no Mac and 
 so no access to the Mac App Store.
This is true.
 Second, from what I see at https://developer.apple.com/xcode/, it's stated 
 that this command line tools part is an optional part of xcode that you 
 can download from within xcode.
Also true.
 So it would mean that to get the command line tools, you need to install 
 xcode first...
It's one way, and the way that I use. However, you can download them directly

 So should we suggest the user to install xcode and then download these 
 optional command line tools?
I say yes, as it seems easier. I have had issues trying to download from the 
Apple dev site.
 Or is this optional part useless once the user has installed Xcode?
No. Just installing XCode does not give the command line tools. You need to go 
into prefs and manually download them.
 Or is there a hidden place from where you can download the command line 
 tools alone as 
 stackoverflow.com/questions/9329243/xcode-4-4-command-line-tools suggests?
It's not very hidden, though it appears to change monthly, and it's different 
if you're on Lion or Mountain Lion.

When I quit the app, it killed the notebook server I had running. As the sws

IMO should go away when the server actually starts.

I had a notebook server running. It handled it fine by taking it over, which

This happened with all languages, and removing the .DS_Store file fixed it. I'm 
guessing this is an OS X general bug, not restricted to ML, but I lack other 
computers to test on.

Re: [sage-devel] Safe-5.3 failed to be built on Mountain Lion (OS X 10.8)

 Hi, John,
 
 Thanks for the tip. I tried it, but no luck :-( The 'make' got stuck pretty 
 much at the same place.

1. Did you try again from scratch? Either by running 'make clean' or unpacking 
the source again.
2. Did you delete the older scipy spkg?

 Sage won't build, as is, on Mountain Lion. Several of us have had good 
 luck with the following procedure:
 
 - make sure you've updated to 10.8.2 (which you have).
 - make sure you've updated to the latest version of Xcode (4.5), and 
 install the command line tools.
 - get the scipy spkg from the link given at 
 http://trac.sagemath.org/sage_trac/ticket/13309, and put it in 
 SAGE_ROOT/spkg/standard.
 - run 'make'.
 
 Good luck!

 Hi everyone,
 In the documentation:

 it states that the eigenmatrix_right() function should give, from a matrix 
 A, two matrices D and P that satisfy:
 
 AP = DP
 
 but in the test, it checks that
 A*P = P*D
 
 Is is an error in the documentation or the code?

A more elegant solution is launchd - like this: http://pastebin.com/DTGcAdMd. 
The important lines are 14 and 15 (to make the run on startup)
Just save the file as label.plist in /Library/LaunchAgents and it should work.

In my experience, this has never happened. Some installs install with sudo 
(well, they ask for my password), but I've never needed it. Normally its used 
when applications install libraries and such in /Library instead of ~/Library 
(so every user can access them), but this doesn't happen with Sage.
 I would rather build in a normal user directory, and then move the whole

 So if 10.0.0 is current, what would be too old to be supported on  
 Sage? I'm
 trying to add a test which will warn people if their OS is too old,  
 but I do not
 know what to check for on the Macs.
I'm not sure what Sage needs and where it comes from in OS X, but  
there are binaries all the way to 10.4, so anything greater than 7  
should work fine.

I've got nothing that old to test on though, so I can't be 100% sure.

This is an educated guess, but

5.x.0 x \leq 5
6.y.0 y \leq 8
7.z.0 z \leq 9

That's if Apple sticked to the naming scheme they claim to use
