About version 2.0

[Alexey Balakin]

Hi,

Yesterday I finished testing the MathGL 2.0 core. So, right now only 3
things hold the release: testing export to 3D formats, updating
documentation, updating UDAV. I don't plan to add new features (except
bugfixes) into the MathGL core or change its API until release.

So, you are welcome to use and test it. In fact, I can make
intermediate RC release right now but I'm not sure that I should.

All the best,
Alexey Balakin

Hi Alexey,

 

where do I find the U3D_LIB ?

For testing mathgl2x I think it needed?

 

Thanks

Walter

Not now. Unfortunately, at this moment U3D support was disabled.

Hi,

[Alexey Balakin]

Hi,

There is special program examples/mg_example which produce images for
most of MathGL plot and options.

Another way -- just take sample code from documentation and use it to
produce the image. Unfortunately, I don't update this samples for new
version. So, generally it should work ... but sometime can be
incompatible with new version.

Is there a documentation about the incompatibilities?

Thanks,

Hi Alexey,

 

I downloaded latest SVN 354, ran complete build process successfully.

 

An error occured running preferred example mgl_example.exe:

 

 

 

 

 

 

The mgl_example was killed after generating the colorbar PNG.

 

Sorry, but this perhaps important?

 

Best regards

Walter

There are a lot of minor changes in order/set of arguments (see
http://mathgl.sourceforge.net/mgl2/mathgl_en/mathgl_en.html or better
one generated from SVN) -- generally I try to make unified order of
arguments for all plotting functions. However, most of plotting
functions keep the same set of required (non-optional) arguments.

There are only few major changes:
1. Class mglGraph is used as replacement for mglGraphZB, mglGraphPS, and
so on. This similar to class defined in <mgl/mgl_w.h> in v.1.*.
2. Class mglWindow is used as replacement for mglGraphFLTK, and so on
3. Each plotting function now have optional argument "opt" for fine
tunning of the plot. This is similar to options in MGL scripts.
4. There are no public variables now. All of them were replaced by
corresponding functions, like TuneTicks => SetTuneTicks(). The only
exception is class mglData.

This is about end-user level. Also there are many changes in the deep...
But it is another story.

Thank you. I'll look at evening on this error in details.

Alexey

[Antonio Scuri]

Ok. Thanks. We are trying to compile our code that used 1.x with 2.0. Something is not right in the configuration files, there are lots of errors. We are going to summarize our problems and send to the list.

Best,

Hi Alexey,

 

I generated libs with SVN 356, but mgl_example crashes again after building colorbar.png.

Dear Walter, thank you for the bug!

I just fix it.

Dear Antonio

I test only Cmake build system with MathGL v.2. And most possible only
one build system will be included in final release.

Autoconf/automake scripts are rather outdated right now.

Hi Alexey,

 

I generated libs with SVN 358, everything is fine,

 

but

 

mgl_example crashes again after building colorbar.png again.

Hi, Walter,

It is strange because I specially check it under winxp. Unfortunately, I couldn't check it again on win7 right now - I run long calculation on my laptop and couldn't reboot it. So, I think tomorrow I'll see it.

Dear Alexey,

 

errors occur on generating MathGL2x libs with SVN359

 

Please see attachment …

Dear Alexey,

 

errors occur on generating MathGL2x libs with SVN360

[mathgl....@gmail.com]

Dear Walter

I remember about it. Unfortunately some of libraries provide this
function for WIN32 ... and my previous solution cause conflicts. So,
I'll write my own variant.

What is the problem with Cont()?

Dear Walter,

It seems that it work correctly in v.2. I'll check v.1 later.

Dear Alexey,

 

I downloaded MathGL2x  SNV362, generated libs up from source, also examples and everything is fine.

Test program mgl_example.exe generates PNG-Images starting alpha.png up to venn.png.

 

Congratulation!!!

 

All the best

Walter
