Now I have not graphic access to mu workstation, but I've tried to sincronize the repository and after hg pull+hg update I have had some problems with different versions of some files, one of them libgui/src/octave-adapter/octave-main-thread.cc that was changed in changeset 16350. The problem is that I'm not an expert in Mercurial and I don't know if I broke something. I can try to compile again next week

José, are you still seeing the message

at startup after Johns changeset 16350 six days ago?

Done in this changeset (http://hg.savannah.gnu.org/hgweb/octave/rev/8650eec57e9f). Marking bug as fixed and closing report.

It works!

Thank you Rik for the patch. It can be added to the octave sources

Thanks for all the testing work you've done. I think we're getting close to a solution.

The GUI is the problem and I have a small patch (patch.setlocale) which I am attaching to this bug report. To test it, download it to the Octave source directory that you are building from and execute

And test whether plotting works. You shouldn't have to set any other locale variables such as LANG or LC_ALL.

My system is Debian GNU/Linux Sid. GCC 4.7.2, QT 4.8.2, GraphicsMagick 1.3.16 and Java Openjdk-7 7u3-2.1.6

One question, how about is Java used?

Normal installation

Without GraphicsMagick

Without Java

In all cases when I run the GUI this message appears in the GUI command line

I know it is the locale setting, but figuring out why it is striking you alone is a bit difficult.

First, are you running the GUI or the command-line interface? I would try both with my guess being that the GUI will work.

Second, Do you have the Graphic Magick libraries installed? If so, can you configure Octave to build without them?

Third, the final place in the code that makes use of locales is Java. If you are compiling with Java, can you try it without?

I've clone the repo (changeset 16135:98b211a163ce) and I've compiled it but the warnings remains:

I backed out a changeset which I believe was causing the problem. Can you get new sources from Mercurial (anything >= 16099:4b6c44096862) and re-build and re-test? If it works I will close this bug.

Thanks. This is just what I expected. I know where the issue is, but I will need to bring it up on the Octave Maintainer's list to figure out best solution.

My locale are configured as Spanish via the systemsettings application from KDE (but the LANG environment variable are not set).

I've set it to en_US.UTF-8 and now the plot works (no warnings appear, as previously). But now when I start ./run-octave appears this warnings:

With octave 3.6.x versions and prior I don't need to change the locales

Attached send the generated files via drawnow

This is interesting. It appears that in your locale the radix separator is ',' rather than '.'.

Can you try running the following:

Then exit Octave entirely and switch your LANG/LOCALE to something else.
The example below uses CSH format for setting environment variables. If you use a Bourne shell you will need to change that.

If the second test works can you upload both .gp files?
