Can not work in matlab in Mac Yosemite about mdsplus HOT 5 CLOSED

I believe this is a problem with Yosemite and it's new security protection. There is an issue with finding libraries with Yosemite if depending on the DYLD_LIBRARY_PATH environment variable which MDSplus does. Unfortunately I'm not a MacOSX expert so I can't help you with this. I know our Mac support people have looked into this problem and hopefully will provide some guidance on how to get it working.

Gabriele -
Have been looking into these problems…. A few things have come up:

1 - I think the stable releases on the web site were no good (should be now)
2 - if I mdsconnect from tditest to alcdata - no problem
3 - if i try to use the mdsdataprovider in jscope to connect I get:
lost connection from: alcdata.psfc.mit.edu http://alcdata.psfc.mit.edu/
followed by ‘datatype code 0 not yet supported’
4 - I have a feeling that if I can not get jScope to work, it is unlikely that matlab connections will work.
5 - if i do not turn off mac’s version of selinux (boot to recovery and type: csrutil disable; reboot) then java applications can not load libJavaMds…

Any ideas ?

To person having this problem:
If you get it to the point where it returns -1, then you are activating all the images, and it is the problem described above with the Connection object.

I tried the latest and the oldest stable release of MDSplus in both Matlab2015 and 2014 and getting the same error:

after i copied everything in the /usr/local/mdsplus/lib/ to ../lib/ the error is gone, but i always get ans=-1 when doing mdsconnect immediately, no timeout.

I also tried the objective way, I get the following error:

c=Connection('someipaddress')
Java exception occurred:
MDSplus.MdsException: Cannot connect to someipaddress
at MDSplus.Connection.(Connection.java:28)

this error comes up without delay, I am sure no network connection is even tried.
I think I followed the install instruction right since I was able to get it working on my Mac Maverick.

Maybe it's not an issue, but I really need to get it work.

Hi Josh,
I tried from here to connect to alcdata using TCP/IP

mdsconnect('alcdata.psfc.mit.edu')

but I get access denied, so I cannot investigate further the reason why
jScope does not connect (it could be related to the fact that some
support funs for jScope are missing on alcdata).

In any case the Java Connection object links against mdstcpip (unlike
jScope that handles the mdsip protocol entirely in java), so if
mdsconnect works, the Connection object should work, too.

                                                  Ciao
                                                 Gabriele

Hi Gabriele,

 You can no longer connect to alcdata because mdsip connections to 

alcdata from outside the psfc are now blocked by our firewall.
Collaborators now either have to ssh to psfc to access data or use the
ssh mdsip plugin.

Ciao,
Tom

The next stable release, and the current alpha release should work with some provisos

1 - Current stable: Nov 06, 2015 MDSplus-7-0-59-osx.pkg - it must be newer than this !
2 - It may not be sending the username to the host on connect. If this is the case then the mdsip.hosts file on host must assign *@the-client-ip to a reasonable username
3 - in El Capitan (i don't think earlier) you need to disable apple's version of SELINUX
