User-defined formulae on Linux

[zypo]

I installed Xaos to my computer running Mandriva 2010.2. It works well
but I can't find the option for custom formula. The Windows version
has that option and it works...

Dear Zypo,

which version do you use? It is displayed on startup, but you should also learn the version number in the file /usr/share/doc/xaos/NEWS.gz.

Best wishes, Zoltan

I have version 3.5 installed. I also noticed that there are "xaos-
aalib" and "xaos-svgalib" packages shown in the package manager and
they're not installed but I think they're not needed... or?

[Kovács Zoltán]

It is probably because there are some missing prerequisities. For user formulas (excerpt from http://xaos.svn.sourceforge.net/viewvc/xaos/trunk/INSTALL?revision=522&view=markup) this is as follows:

To support user-defined formulas, you need ONE of the following:

 * nasm from http://www.nasm.us/

 * gsl from http://www.gnu.org/software/gsl/

NOTE: Nasm will only work on x86 architectures, but GSL should work on any modern platform.

HTH, Zoltan

I installed GSL library (package: libgsl0) and then tried to reinstall
Xaos but the user formula option doesn't still appear. Or did you mean
that I should compile Xaos myself?

Yes, please install it from source (i.e. compile it yourself). It seems the factory version of XaoS was compiled without the GSL library support (i.e. the user formulas will not work at all).

Best regards, Zoltan

Thank you very much! :D I installed a huge bunch 'o libraries (xlib,
zlib, libpng and gsl but xlib required lots of other packages as well)
and then compiled it and it seems to work well. I used GCC 4.4.3. By
the way, I noticed that the Xlib libraries are called "libxorg-X11"
and "libxorg-X11-devel" (I suppose that these developement library
packages should be installed when compiling stuff?), at least in
Mandriva's repositories. Searching for "xlib" returns nothing.
