Two possibilities: output an errormessage telling the user what's missing
where or installing a personal versinon of the files in the user's home
directory.

Hmmm, I'm not sure, but if you look at admin/acinclude.m4.in (where the
KDE_FIND_PATH ist defined) it has copyright messages up to 1999... But
again, I'm no expert, just a guess.

How do other applications perform the task of getting the right paths? Did
you look at the output of a KDevelop generated project? Btw, are you using
KDevelop? There is a project file, but e.g. the admin/ stuff we are
talking about here doesn't seem to be autogenerated to me...

Hmmm, strange. ldd says that kmatplot/kmatplot is not a shared library! So
I assume it is linked statically. At the moment I'm recompiling with
--with-kde-dir=3D/opt/kde2 and --with-qt-dir=3D/usr/lib/qt2. This takes qui=
te
a long time on my 300 MHz MII, so I assume I'll probably be able to give
you more success or error reports tomorrow morning.

I'll try it again if my current comiler run has finised and keep you
informed.

Sorry, a misunderstanding - there was no post here. I talked to Torsten
some time ago about another problem and during the discussion he mentioned
that KDEDIR should be obsoleted at that time; I'm not sure if this is
really the case in the mean time or not (havn't compiled KDE myself for
some time...).

I'm afraid I didn't get it to work without installing before, you can't point 
KDEDIR to your build directory- it won't work, but you can always install it 
in your home directory. If you install a shared library in a non-library 
directory, you must also add it to LD_LIBRARY_PATH. Check if it works:

./configure --prefix=/home/kamil/kmatplot
make install
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/kamil/kmatplot/lib
env KDEDIR=/home/kamil/kmatplot kmatplot 

Did you do so ? I didn't see the post from Tortsen and I know nothing about 
obsoleting KDEDIR. It still must be set when program is installed in a 
non-standard directory.

Strange. I send a copy of this mail to Torsten Rahn from the KDE team,
perhaps he can give us some comments.

Hmmm, shouldn't be too hard to check if the files are in the assumed
places? Unfortunately, I don't know enough of the KDE stuff yet to be
really hepful in this department.

Not being an expert in autoconf things, this seems to be a problem with
your autoconf configuration files in the admin directory which seem to be
taken from a KDE1 installation.

Hmmm, at the moment I didn't install kmatplot at all, I just wanted to
test it in the directory where it was compiled. If I understood Torsten
correctly some time ago the KDEDIR variable is obsolete and is not being
used any more? However, compiling and starting from the directory without
being installed should always work, I assume. But also following your
hints doesn not work, I get the same error...

Missing extension isn't a big problem ( it is present in XFree4.0.0 ). 
I bet that it is a common problem with SUSE. Oh, remember that those 
./configure scripts are written by KDE guys, the one I use was released with 
KDE 2.1.1 and it often fails to configure the build properly, especially on 
Suse. 
 
KMatplot crashes after startup if it can't find its resource files, which it 
try to find in standard KDEDIR directory. KDEDIR is named /opt/kde2 ( SUSE ), 
but for some reasons 'configure' script is trying to install the program into 
/opt/kde, which contains KDE1 files. If KMatplot installed itself in a 
non-standard directory you must pass this directory in KDEDIR variable. Run 
terminal and check if it works:
 env KDEDIR=/opt/kde kmatplot
 env KDEDIR=/usr kmatplot
 env KDEDIR=/opt/kde2 kmatplot

You can reinstall KMatplot in a different directory ( forcing using a 
standard KDEDIR ) with commands.
 ./configure --prefix=/opt/kde2
 make install

 Check also if KMatplot resources directory is readable end executable for 
all users ( r-x ). Common places are /opt/kde2/share/apps/kmatplot, 
/opt/kde/share/apps/kmatplot, /usr/share/apps/kmatplot
 drwxrwxr-x 4 root root 4096 lip 12 15:19 kmatplot

[Kmatplot-general] Problem on SuSE 7.2

[Robert S. <ro...@sc...>]

Hi,

I have problems installing kmatplot-0.2.2 on SuSE 7.2. Compiling does work
now, but starting doesn't:

callisto:/usr/local/kmatplot-0.2.2/kmatplot # ./kmatplot
Xlib:  extension "RENDER" missing on display ":0.0".
FATAL: Error loading libkmatplot:
KCrash: crashing.... crashRecursionCounter =3D 2
KCrash: Application Name =3D lt-kmatplot path =3D <unknown>
Xlib:  extension "RENDER" missing on display ":0.0".
callisto:/usr/local/kmatplot-0.2.2/kmatplot #

Any idea what could be the reason for this? What's this strange RENDER
extention that seems to be missing?

[Kmatplot-general] bugs in Kmagplot 0.2.2(with attachments--ignore previous)

[Obed S. <Obe...@gr...>]

I've built kmatplot 0.2.2 under SuSE Linux 7.2. Along
the way I've found a few bugs. The first attachment is
contains a couple of context diffs for the bugs that I
fixed. The first bug gets rid of an unterminated comment
and the second removes an un-necessary include file that
couldn't be found under my Linux install.

The second attachment gives the text of a crash report.
Once kmatplot starts it crashes, for me.

I find the goals of kmatplot very attractive and would
like to use kmatplot and help with bugs where I can.
However I'm not really equipped to deal with alpha code.
What is the relative level of maturity of kmatplot?

I'm afraid there is no separate library. Of course I plan to release such 
library in the future, when API will mature enough. Look at /widgets 
subdirectory of the KMatplot source tree, where all files for that library 
are placed. There are two simple demos in /demos subdirectory. You can even 
generate ( using kdoc or oxygen ) some docs, but they are partially outdated, 
so can be misleading ( you can always mail me your questions ) but the major 
problem is that there are major changes planned, so probably succesive 
versions will be incompatible with this version.

[Kmatplot-general] KMatplot widgets?

[Felix E. K. <fel...@in...>]

Hi,

when I write GTK+ code I usually use the gtkextra plot widgets
to display plots. They were created by Adrian Feiguin for his powerful
Scigraphica plot program. However, I also would like to use ready made
plot widgets when writing QT code. Therefore my question:

 Are the widgets created for Kmatplot available as a seperate package?

There is "LENGTH" parameter on an axis panel - use parameter of the X, Y or Z 
axis to change proportions of appropriate edges.

[Kmatplot-general] getting y-axes for surf. plots to work

[Robert E. P. <pa...@fa...>]

Hi, 

I'm trying to import some surface data into kmatplot, and I'm having
trouble with the y axis values. I have specified a row vector of x-values,
a column vector of y-values, and a matrix of z-values. The z and x-values
are correctly imported. but the y-values aren't. They are accepted in the
import dialog box, but the y axis on the surface plot itself are the
default (1,2,3,4...) instead of the values I supplied, which range between
-1 and 1.

Is this a known bug?

I'd really like to see the x-y plane of the surface plot with the correct
proportions (in my case 1 by 2) instead of the default square proportions.

any ideas?

thanx,

[Maurizio U. <un...@jl...>]

This is just to say
I hope kmatplot will improve, I think it's a really
nice program.
I cannot yet use it because of my data format, but
I'm looking forward to new release.

I'm in particle physics, currently using ROOT but
looking around for better and kmatplot has good premises.

Yes it's Octave-like format:

#name: x
1 1 1 2 2 2 3 3 3 
#name: y
1 2 3 1 2 3 1 2 3

And I'm afraid there is no option for easy importing such 
data into KMatplot, you can use Octave to convert this format and load it 
into Kmatplot. Currently data management is very straightforward - I plan to 
add something like a global list of matrices ( worksheets ), so any plot can 
refer to any range in the any global matrix. But writing the second tecplot 
will take time surely, now I'm adding pixmap export and next in queue is 
adding scatter 3D plots, so it is the third option, so stay tuned.

[Kmatplot-general] ascii data format

[Kees v. W. <C.v...@st...>]

I use some visualization tools like matlab or tecplot one various sytems. 
Though on my linux PC I don't have any of these available and kmatplot might 
be a good alternative in some cases except that kmatplot uses a ascii data 
format which most of my programs (c, fortran) can not write. Most of these 
programs write data in columns where each column represents a variable.

e.g.:

x  y  u    v
1  1  3.2  1.1
1  2  3.1  4.3
1  3  1    3
2  1  3    7
2  2  7    4
2  3  5    7
3  1  4    5
3  2  3    5
3  3  2    3

Is there any option to read in ascii data this format?

Since many of my data analysis programs write data this way (optionally using 
some header information about the exact format) it would be a nice 
feature...for me.

What is the idea behind the current "#name: ...." format? Is it Octave stuff?
