Hi list,

I would like to test Octave GUI but it's difficult to find a
tutorial
in google (GUI Octave, ... )
Any help? References? Howto?

I know that Octave GUI is unstable.

Could be these included in FAQ?
The response now is not enough for me :/
http://wiki.octave.org/FAQ#GUI

I'm in Lubuntu 12.10 and I have Octave version 3.6.2 from official
repositories.

Greetings,
Pedro

Hi Pedro,

I think this mail should go to the help mailing list.

You need to checkout the default repository and compile it from
source.
Follow the instructions here
http://www.gnu.org/software/octave/get-involved.html

Once you go the code do
$ hg update default
$ ./bootstrap
$ ./configure
$ make
$ ./run-octave

Make sure that ./configure tell that you are OK to compile. Also
when
making you can pass the -j<n> option, where <n> is the number of
processors/cores you have in your machine.
I do not know what kind of update system you have in Lubuntu, just
run
the equivalent to
$ sudo apt-get install buildessential
$ sudo apt-get builddep octave

before you start compiling to get all the dependencies. You will
also need
libqscintilla2 and qt4

Ok, I have an make error. But first, I make a description to arrive
here:

./bootstrap
says: "build-aux/bootstrap_gnulib: one of these is required:
glibtoolize libtoolize"
=> you have to install "sudo apt-get install libtool"
=> (and) "sudo apt-get install automake autoconf"

./configure
sudo apt-get install libpcre3-dev
sudo apt-get install libblas-dev liblapack-dev

make
here's the error [1]
I tried to resolve installing:
sudo apt-get install flex flexc++ flexbackup libfl-dev flexloader
flexml
(also flex-old, and this remove flex and libfl-dev)

information
flex version: 2.5.35-10
libfl-dev version: 2.5.35-10
flex-old version: 2.5.4a-10

Try first getting the dependencies

$ sudo apt-get build-dep octave

if you are in a Ubuntu older than 12.10 you need to do

$ sudo apt-get build-dep octave3.2

Also notice that bootstrap is telling you that there are some
programs missing.

Thanks for your reply.
About depmode. I was thinking that was a program... aplying
incorrectly sudo apt-get install build-dep octave

So I did:
# sudo apt-get build-dep octave
# make clean && ./bootstrap && ./configure && make

and here's the ouput error:
http://pastebin.com/yhm4NcmK

Something bad with lex.cc & lex.ll
Seems to be missing a library

Now I will try a new hg clone of sources and try again (instead of
using make clean)

Try manually installing lex

$ sudo apt-get install flex

What GNU/Linux are you using?

Lubuntu 12.10 (quantal)

$ sudo apt-get install flex
(...)
flex is already the newest version.

$ flex -V
flex 2.5.35

An alternative is to use:
"flex-old" with: 2.5.4a-10
but it will remove:
libfl-dev version: 2.5.35-10
don't know if affects

Ok, I had to ask help to jwe for this one.

Make sure bison is installed

$ sudo apt-get install bison

If that doesn't do the trick then

09:12:21 PM) jwe: what is in the generated
libinterp/parse-tree/oct-parse.h file?  That's where things like DO,
END, ELSE, etc. should be defined.

$ sudo apt-get install bison
It wasn't installed, thanks

$ make clean && ./bootstrap && ./configure && make

It seems that generate the same error:
http://pastebin.com/4hRT6s73

./libinterp/parse-tree/oct-parse.h
not found

/octave/libinterp$ ls
http://pastebin.com/2kExw14R

(This night I will do a fresh build with new sources: hg clone.
Perhaps too much "make clean")

Hi Pedro,

Could you pastebin the result of the configure script?

I am CC the maintainers list, there is more people here that compiles
the sources often and they may have a better idea what is the problem.

@Maintainer: Pedro is trying to compile the default branch to test the
GUI. He has installed (apparently) all dependencies. He is using
Lubuntu 12.10 (quantal) . Does anybody has a clue why he can't
compile?

I would like to please join this discussion, I have now reached the point where I can't go further (After having built Octave many times before.

My system is X86-64 with *Gb RAM running Ubuntu 12.04

$ ./run-octave gives perfect results, I could open a .m file (actually the project consists of several .m files) hitting the run button gives all my graphs! So, I thought success.

Now I do

$ make check results in;

  PASS     10570

See the file test/fntests.log for additional details.

Expected failures (listed as XFAIL above) are known bugs.
Please help improve Octave by contributing fixes for them.

355 (of 937) .m files have no tests.

0 (of 122) .cc files have no tests.

Please help improve Octave by contributing tests for
these files (see the list in the file fntests.log).
