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:
- Clone the repository:
$ mkdir adios2
$ cd adios2
$ git clone https://github.com/ornladios/adios2.git source- Create a separate build directory:
$ mkdir build- 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
...

$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. |
