Getting Started

ADIOS2 uses CMake for its build environment. CMake expects projects to use "out-of-source" builds, which means keeping a separate build and source directory (different from autotools, which usually uses an in-source build).

To build ADIOS2:

1. Clone the repository:

$ mkdir adios2
$ cd adios2
$ git clone https://github.com/ornladios/adios2.git source

2. Create a separate build directory:

$ mkdir build

3. Configure the project with CMake:

$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/opt/adios2/2.0.0/gnu/openmpi ../source
-- The C compiler identification is GNU 6.3.1
-- The CXX compiler identification is GNU 6.3.1
...

ADIOS2 build configuration:
  ADIOS Version: 2.0.0
  C++ Compiler : GNU 6.3.1
    /usr/bin/c++

  Installation prefix: /opt/adios2/2.0.0/gnu/openmpi
  Features:
    Library Type: shared
    Build Type:   Debug
    Testing: ON
    Build Options:
      BZip2    : ON
      ZFP      : OFF
      MPI      : ON
      DataMan  : ON
      ZeroMQ   : ON
      HDF5     : ON
      ADIOS1   : OFF
      Python   : ON
      C        : ON
      SysVShMem: ON

The following options can be specified with CMake's -DVAR=VALUE syntax to control which features get enabled or disabled:

CMake Option	Values	Description
ADIOS2_USE_BZip2	AUTO/ON/OFF	Enable BZip2 compression (not implemented).
ADIOS2_USE_ZFP	AUTO/ON/OFF	Enable ZFP compression (not implemented).
ADIOS2_USE_MPI	AUTO/ON/OFF	Enable MPI.
ADIOS2_USE_DataMan	AUTO/ON/OFF	Enable the DataMan engine for WAN transports.
ADIOS2_USE_ZeroMQ	AUTO/ON/OFF	Enable ZeroMQ for the DataMan engine.
ADIOS2_USE_HDF5	AUTO/ON/OFF	Enable the HDF5 engine.
ADIOS2_USE_ADIOS1	AUTO/ON/OFF	Enable the ADIOS 1.x engine.
ADIOS2_USE_Python	AUTO/ON/OFF	Enable the Python >= 2.7 bindings.
ADIOS2_USE_C	AUTO/ON/OFF	Enable the C bindings library libadios2_c.so or libadios2_c.a

Note: The ADIOS2_USE_HDF5 and ADIOS2_USE_ADIOS1 options require the use of a matching serial or parallel version depending on whether ADIOS2_USE_MPI is enabled. SImilary, enabling MPI and Python bindings requires the presence of mpi4py.

In addition to the ADIOS2_USE_Feature options, the following options are also available to control how the library get's built:

CMake Options	Values	Description
ADIOS2_BUILD_SHARED_LIBS	ON/OFF	Build shared libraries.
ADIOS2_ENABLE_PIC	ON/OFF	Enable Position Independent Code for static libraries.
ADIOS2_BUILD_EXAMPLES	ON/OFF	Build examples.
ADIOS2_BUILD_TESTING	ON/OFF	Build test code.
CMAKE_INSTALL_PREFIX	/path/to/install (/usr/local)	Install location.
CMAKE_BUILD_TYPE	Debug / Release / RelWithDebInfo / MinSizeRel	The level of compiler optimization to use.

4. Compile:

$ make -j8
