Installing CGNS libraries

nba1942 · November 14, 2014, 03:15

Hi, I am working on unstructured grid and a solver for it. I read lots of pdfs from "http://cgns.sourceforge.net/" and now I know I should use CGNS libraries to export BC, solutions etc from CGNS data.

But those pdfs don't tell me what to do to install the libraries. And one of my colleagues who had installed the library on Linux told me what he did to install it, but obviously that doesn't work for on windows.

I am using Windows 8.1 and am working with fortran. I tried using "Visual Studio Command Prompt" and that didn't work. I want to try using "Cmake", as the "read me" told me to, but I really don't know where to start.

What I want to ask is;

1. Is it possible to install to install CGNS library on Windows OS?

2. What does "compile" means when it comes to installing the libraries? I know installing a library is not different from just clicking "install". So when I try to compile something to install CGNS libraries, what am I doing??

I am desperately waiting for any reply.

Thanks for reading.

I get the impression from your questions that you may not be an experienced programmer. Building the CGNS libraries from source code is NOT trivial. Depending on your specific IO requirements, you may also need to obtain or build ADF, HDF5, and MPI libraries! You may want to consider looking for pre-built libraries from a trusted source. It will save you a lot of headache.

The CGNS website suggests that they support cmake. If it is properly configured for windows, then cmake will do a lot of the work for you.

Are you required to use CGNS? If not, there are other well documented, grid file formats that are much easier to work with. If your grid files are not too large, I suggest using an ASCII grid format. ASCII files are easier to write and debug.

You are right. I am a graduate student and this is my first year to study in the lab

haha lots of things to learn..

About my situation, my professor is coding an unstructured solver and until now, his solver was for only structured grid with techplot format.

I think we should use CGNS libraries to import BC into the new solver to start calculation and to manage the solution data.

###############################################

I already installed HDF5.

the source codes are located at

C:\Users\Kim\Desktop\CGNS\cgnslib_3.2.1\src

and I want to build them to

C:/Users/Kim/Desktop/CGNS/installed

as you can see from figure 1. And I specified the generator as "VS 12 2013".

Then I encounter the error as you can see from figure 3.

###############################################

I googled the error and I read a comments saying that I should do "ccmake",
which I have no idea what it is yet. Figure 4 is what I encountered.

Your replies are always so helpful. Thanks for your reply, dgarlisch

waiting for reply!

Hi,

You may install cygwin, and then install the CGNS in your windows like what your friend did in linux. Besides, you can also read the step 8 from here, and also follow it in for the future section.

Good Luck,
PDP

If the error message is accurate, you need to add a cmake_minimum_required() macro to the top level CMakeLists.txt file.

For details see: http://www.cmake.org/cmake/help/v3.0..._required.html

As PDP suggested above, you may be able to get away with building everything with cygwin. Cygwin is a unix-like environment for winOS that includes gcc. I am not sure if cygwin generated libs will link properly with microsoft generated libs. So, for link compatibility, you may (or may not) need to rebuild the HDF5 libs with cygwin.

Good luck.

I think I will try a lyx installer for windows first. I found the "install.lyx" in the library folder.

My colleague says that he installed it through that file. Maybe I can try this before I start something complicated

Anyway thanks for your help!!

hi nba1942：
I recently also try to install Cgns on windows. I install it with MVS 2010 and inter fortran 2011. I used nmake but it always warn me can not find "Cgns.lib". I also tried cmake and still failed. Have you succeed in installing and would you tell me how to install it on windows and which c and fortran compiler should I take. Thank you very much. Expecting to hear your reply!
