The link in comment #7 lists all dependencies that are needed to build from the repository. It also lists possible commands to install those dependencies on certain distributions.
There is no need to skip building the documentation if those dependencies are installed.

I'm sorry if I made you feeling urged to do something. I thought I just asked you if you could provide a patch. That wasn't meant to be an order. :-)

New and interested testers and contributors are always welcome. We'd love to help by answering any questions. But maybe the bug tracker is not the best platform for that.

By no means i am so arrogant to consider myself an octave developer.
I just ventured to build from repo
because markus urged me to provide a patch.
This is not what i want. But i wanted to serve.

I did read. https://wiki.octave.org/Building
Where is the flag --disable-docs mentioned in a docs?

@markus, i will in future critically ask myself
whether i just rephrase a question as a feature request.
I was not aware of doing so.

I just try to get again/ keep my work running with octave
which is by no means easy.

I agree with Rik. If a developer/tester tries to build from the repository, we probably can expect them to read the respective instructions (e.g. [1] for instructions on Ubuntu/Debian).

Also the condition outlined in comment #4 is incomplete. Like Rik already wrote: If a user builds from a release tarball, these dependencies are optional because the documentation is already included. No need to mandate "--disable-docs" in that case.

If a configuration fails with a release tarball, this would be a valid bug. Like it is, I'll close this report with the status it already has ("won't fix").

@Ernst: Recently you opened a lot of reports where you asked for help with XYZ. (Often rephrased to something like "Octave doesn't have a function to do XYZ" or "Octave fails on doing XYZ".)
Many of those are good questions. But we have to close those reports as "invalid" or "won't fix" on the bug tracker.
Please, use one of the more appropriate channels for those questions (like the help mailing lists, discourse, or IRC [2]).

The option '-jN' sets the number of processes that make will run in parallel.  If you have multiple CPU cores or multiple threads per core then you want to use a number above 1.  I have a total of 8 threads (4 cores with 2 threads each) on my PC so I run 'make -j7' which gets the compilation done faster but still leaves a spare thread for surfing the web or doing other things.

just because i am curious about:
make -j2: what is the meaning of the mysterious `-j2`??

Well, a novice.... If someone wants to at least file bug reports,
one sometimes has to build, e.g. because maybe a real developer asks you whether a certain version works for me.

Then maybe one has to provide a patch... and so on.
So one quickly becomes a kind of developer. 
It is easier to get into if the build system has not so much quirks.

I think, make is not the right place to solve the problem,
since configure (without --disable-docs) makes the wrong suggestion that make will work.
So configure has to check whether --disable-docs is present.
Only in this case, the output is ok.
If without that, an error shall be displayed
and a hint to disable docs.

Then make can remain as is.

This is the root of it.  If you are building from Mercurial sources the expectation is that you are an Octave developer and are familiar with the requirements/quirks of the build system.

There is a check to make sure that any system where you build Octave that cannot create the documentation is unable to then make a distribution tarball.  The Makefile code is in doc/interpreter/module.mk and is

# Prevent packaging of distribution unless all libraries
# necessary to create documentation are present
doc-interpreter-dist-hook:
        @$(GREP) '#define HAVE_COLAMD 1' $(top_builddir)/config.h > /dev/null || { echo "Documentation creation requires missing COLAMD library.  Cannot package distribution!" ; exit 1; }
        @$(GREP) '#define HAVE_CHOLMOD 1' $(top_builddir)/config.h > /dev/null || { echo "Documentation creation requires missing CHOLMOD library.  Cannot package distribution!" ; exit 1; }
        @$(GREP) '#define HAVE_UMFPACK 1' $(top_builddir)/config.h > /dev/null || { echo "Documentation creation requires missing UMFPACK library.  Cannot package distribution!" ; exit 1; }
        @$(GREP) '#define HAVE_QHULL 1' $(top_builddir)/config.h > /dev/null || { echo "Documentation creation requires missing QHULL library.  Cannot package distribution!" ; exit 1; }
        @$(GREP) '#define HAVE_QT_OFFSCREEN 1' $(top_builddir)/config.h > /dev/null || { echo "Documentation creation requires Qt offscreen OpenGL rendering.  Cannot package distribution!" ; exit 1; }

There might be a way to do something similar for 'make all' that issues an error message if the documentation can't be built.

It might also be possible to write configure code in configure.ac that would check for the required libraries and issue a warning during configuration, rather than during compilation with make.

I verified almost.
make check
did not succeed.
make -j2 did succeed.

But to be honest, this is a bug to be fixed,
because the output of configure is misleading.
If configure is run without `--disable-docs`, it must output an error because it is not possible to run make successfully.
The error must include the suggestion to run with `--disable-docs`.
Else how can a novice know how to build?

You can build Octave without CHOLMOD, but you can't build the documentation without COLAMD, CHOLMOD, UMFPACK, QHULL.

One option is to run configure with '--disable-docs' to avoid creating the documentation.

Another option is to download a tarball of a release, such as the new 6.2.0, which includes a complete set of documentation.  Because the documentation already exists, the host machine is not required to have the extra libraries.

then make -j2

This fails with

I think this is not ok, because before i had warnings only
and it is possible to run octave without CHOLMOD
