hanzj is still having a problem:
Hello,all,
hello,Anton and Klaus Thoeni,
Sorry for reply so late. I have tried to install the pre-required libraries as your recommendation, I am now facing the problem is
the installation of minieigen. I have download the minieigen-0.5.3.tar.gz from http://eudoxos.github.io/minieigen
and I tried to install it using the comand python setup.py install
 but
(1) I came across the error:
  File "setup.py", line 23
    libraries=['boost_python-py3%d'%sys.version_info[1] if py3k else 'boost_python']
                                                         ^
SyntaxError: invalid syntax

(2)also ,I can not understand the command in the README.txt as follows:

To compile by hand under Linux, run something like

    g++ -ansi src/miniEigen.cpp src/double-conversion/*.cc -o
minieigen.so -shared -fPIC `pkg-config python --cflags` -lboost_python
-I/usr/include/eigen3

and the whole README.txt as follows:
This is miniEigen, small wrapper for the http://eigen.tuxfamily.org library.
Home of this project is at http://www.launchpad.net/minieigen/. The code is
licensed under the LGPLv3. The author is Václav Šmilauer <eu@xxxxxxxx>.

Documentation is uploaded to http://eudoxos.github.io/minieigen.

Run `python setup.py install` to build & install this module. You will need the
boost_python library to be installed, and Eigen (in /usr/include/eigen3, or
somewhere where the compiler finds it).

Windows is experimentally supported, but paths must be tweaked in setup.py
to match your system. Suggestions for a better way are welcome.

To compile by hand under Linux, run something like

    g++ -ansi src/miniEigen.cpp src/double-conversion/*.cc -o
minieigen.so -shared -fPIC `pkg-config python --cflags` -lboost_python
-I/usr/include/eigen3

Enjoy.

(3)If I am not going to install the minieigen, could I comply yade to
install? must I install it? I have tried without it, but complied
failed.

Any suggestions?
Thanks a lot.

Han Zhijian
