安装以及编译SU2的几个问题

sxhqjfl

我用的是ubuntu系统，已经安装好了python, numpy,scipy,并且将metis4.0.3放到了trunk文件夹下

1. 如何安装OpenMPI? 由于我对linux不懂，就从ubuntu的软件中心搜索了openmpi,安装了这个（如图），请问这个对吗？

2. 如何编译SU2？我从SU2的官网上看到的东西：

As of release 2.0, SU2 uses the GNU automake tools to configure and build the software from source in Linux and Mac environments. To compile the most basic version of SU2 (single-threaded with no optional features and no compiler optimization), navigate to "your_SU2/trunk" and follow the usual steps after extracting the source code:

./configure     (make sure to note the SU2_RUN and SU2_HOME variables displayed at the conclusion of configure)
make
make install

To use the more advanced features of SU2, you will need to add environment variables and update your path.
Tuning of the build process, setting environment variables, and adding optional features is discussed below.


可是我的trunk文件夹下面根本就没有configure文件。怎么办？
