Re: [Burrtools-discussion] burrtools lib

[<M.K...@t-...>]

Hello

Thank you for your answer.

Now I can compile the development version of the burrtools lib.
Therefore, I import the folder /src/lib into a c++ project in eclipse
and add a c++ file with a main() function (for example burrtxt.cpp).
This works.
I'm not able to use ./configure && make to compile because there is no
conifgure script and I did not succeed in building this script from
configure.ac. wikipedia (http://de.wikipedia.org/wiki/Configure) says
that I can try $ autoreconf but this doesn't work in msys: 

  configure.ac:26: required file `admin/compile' not found 
  configure.ac:26:   `automake --add-missing' can install `compile'
  configure.ac:11: required file `admin/config.guess' not found
  configure.ac:11:   `automake --add-missing' can install `config.guess'
  configure.ac:11: required file `admin/config.sub' not found
  configure.ac:11:   `automake --add-missing' can install `config.sub'
  configure.ac:17: required file `admin/install-sh' not found
  configure.ac:17:   `automake --add-missing' can install `install-sh'
  configure.ac:17: required file `admin/missing' not found
  configure.ac:17:   `automake --add-missing' can install `missing' 
  src/Makefile.am: required file `admin/depcomp' not found
  src/Makefile.am:   `automake --add-missing' can install `depcomp'
  Makefile.am: required file `./INSTALL' not found
  Makefile.am:   `automake --add-missing' can install `INSTALL'
  Makefile.am: required file `./ChangeLog' not found
  Makefile.am: required file `./COPYING' not found
  Makefile.am:   `automake --add-missing' can install `COPYING'
  autoreconf: automake failed with exit status: 1

How can I do this with msys/mingw?

In the last mail you mentioned that there is a kind of piecegenerator in
the development version. I did not find this, neither in the source
files nor in the documentation made with doxygen. Could you please tell
me the name of the .h file or the class where I can find the
piecegenerator?

Thank you for your help.

Hello,

Please don't use HTML for emails. I tend to immediately remove them due
to 
spam.

The inherited classes are for the special space grids while the base
class 
contains common functionality. The special code is mainly about 
transformation (rotation) of the voxel space and also about finding
neighbor 
voxels. The numbers are as follows 0 for brick, 1 for triangular, 2 for 
spheres, 3 for rhombic, 4 for tetrahedral octahedral grid.

Normally you are not supposed to use the constructors directly. If you
want a 
voxel space that fits into a certain puzzle p use

p->getGridType()->getVoxel(.....) 

functions. They will always return the proper derived class. Also you
nearly 
nowhere need to construct the classes directly. Most of the time (well
in 
cases with derived classes) you will use the gridType factory. It
contains 
factory functions for all those hierarchies.

Sorry, but the release version of 0.4.2 doesn't contain a valid piece 
generator. In the development version that file is removed. I never got
that 
finished. The development version does contain something that is
suitable for 
constructing some pieces but it works differently.

Best would be to download the current development version (using darcs)
and 
look there. There are many (really many) changes in there. The new piece

generation functions are documented in the manual, so you can look
there, or 
ask here once you get the development version running.

It is certainly possible to generate pentominos and hexominos with it.
