_ROCK_ is developped in C++ 98 and is C++11 compatible.
On computers with [gcc](https://ftp.gnu.org/gnu/gcc/)(version at least 4.4.7) or [clang](https://clang.llvm.org/)(version at least 503.0.40) installed, the compilation and installation of _ROCK_ can be carried out using the following command lines:

If you don't plan to add new files to ROCK's source code, you do not need anything else than one of the compilers mentionned above and the make tool.
First thing to do is to run:
```bash
./configure
```
This will generate the files needed by make to produce the executable with the default options.
Two things are important here:
1) To get the best performances, you must pass the -O3 flag:
```bash
./configure CFLAGS='-O3'CXXFLAGS='-O3'
```
2) You do not need to install ROCK on your system to use it. You can simply run the executable that make generates in the src directory.
Yet, if you want to install it in your system's default location for executables; then make sure that you have sudo rights for that.
A way to install ROCK on your system without sudo rights is to provide the configure script with another directory path. This can be done with the --prefix option of the configure script.
