GiDPost can be build as library to be linked into the calculation program or as python module (look into As python module ).
This page explains how to build gidpost as library to be linked to you program.
Third part libraries:
- zlib: it is necessary previously obtain or compile the zlib compression library (www.zlib.net)
- hdf5: this library is optional www.hdfgroup.org. Required only to write postprocess files with this format (files opened with GiD_PostHDF5=3 flag)
To build GiDPost as Python module you'll need:
- python3
- SWIG: (Simplified Wrapper and Interface Generator) a tool used to connect C or C++ code with scripting languages like python. https://www.swig.org/
To install the required packages in Linux just do the following as root:
Ubuntu (Debian and the like):
| Code Block |
|---|
apt-get install zlib1g-dev libhdf5-serial-dev apt install python3 swigdev libhdf5-hl-100 ;# version number depends on linux distribution and version apt-get install hdf5-tools hdf5view ;# recommended tools to manage and look into hdf5 files |
Scientific Linux (Redhat and the like):
| Code Block |
|---|
yum install zlib-devel.x86_64 hdf5-devel.x86_64
yum install python3.x86_64 swig.x86_64 |
Note:
Bear in mind that there are several hdf5 development packages and that you should choose the right for you.
For instance, in Ubuntu these are the HDF5 development packages available:
| Code Block |
|---|
libhdf5-mpi-dev
libhdf5-mpich-dev
libhdf5-openmpi-dev
libhdf5-serial-dev ;# by default the package 'libhdf5-dev' installs the -serial version |
And in Scientific Linux the HDF5 development packages available:

How to build (Linux - gcc):
| Code Block | ||
|---|---|---|
| ||
$ cd .../gidpost $ mkdir build-linux $ cd build-linux $ cmake -DHDF5=ON -DBUILD_FORTRAN_EXAMPLES=ON .. ;# gfortran is needed to BUILD_FORTRAN_EXAMPLES (by default it's off) $ make $ cd examples $ ./testc -help ;# to view format options $ ./testc -f hdf5 ;# to write a gid post file in hdf5 format $ ./testf90 ;# fortran 90 example writing hdf5 gid post file |
How to build python module (Linux):
Once you have configured and buil the GiDPost library, then:
| Code Block | ||||
|---|---|---|---|---|

$ cd .../gidpost/gidpost-swig/
$ make
$ make test |
