truss needs procfs:
mount_procfs /dev/mem /proc

I cannot truss anything

victor# truss /bin/echo "hello"
truss: cannot open /proc/curproc/mem: No such file or directory

any other solution or workaround?

Could you please script (1) a session with only `truss FreeMat', just
calling the help and exiting? Then please send me the compresed log of
this session.

If you had created some symlinks, please don't forget to remove them.

Yes, with the new version 3.1 inv now works fine. Unfortunately the "Help on 
line" still doesn't work. I think that something worsened because with this 
new port now I cannot use the help on line even as root (in the previous 
version "Help online" as root worked quite well).

Hello,

I have just upgraded FreeMAT to 3.1, which fixes the inv() problem, and
which should fix this "Help on line" bug too; could you please check it?

No, it still doesn't work. I launched what you suggested (see below) then 
again 'FreeMat' but when I ask for the "Help on line" nothing happens and the 
system answer as below (see QTextBrowser's lines) 

victor$ FreeMat -i /usr/local/share/FreeMat-3.0/
FreeMat root path set to '/usr/local/share/FreeMat-3.0/'
victor$ FreeMat
QTextBrowser: Cannot open 'file:///index.html' for reading
QTextBrowser: No document for file:///index.html

Ciao
Vittorio

P.S. By the way, launching FreeMat as root the "Help on line" works whilst inv 
still doesn't work. Ciao Vittorio

I had forgotten about that, but I think that the first time I had
launched

FreeMat -i /usr/local/share/FreeMat-3.0

and then it uses QSettings to store this path persistently.

Could you please try it, and if it solves this problem, I'll add a post-
installation message?

You're right: I have no problem to run the examples and the classical
functions are OK, simple operations on matrix are OK, but inv() hangs.

I'll report this to the author.

It's working on my machine, but the same problem has been reported in PR
ports/109469 .

Could you please send me output of truss when you just launch FreeMat
and call helpwin?

Could you please also try again from the package (`pkg_add -r' should be
OK).

I'd like to fix it!

FreeMat 3.0 doesn't call functions and help

[Vittorio De Martino]

I've just installed FreeMat 3.0 from the ports in my i386 6.2 box but, while 
it is able to accomplish simple calculations it is not able to use the 
functions e.g to invert a matrix

a=[1,2;-4,3]
inv(a)

instead of inverting the matrix hangs endlessly.

Besides if I ask for the "help on line" (OR helpwin) the following error 
messages pops up  

"The file modules.txt is missing from the directory  where I think help files 
should be."
 
I think I didn't configure something but I don't know what (the main.pdf 
manual isn't that helpful as far as the installation is concerned).

Could someone out there help me to start FreeMat?
