This is not particular question about SU2, but I think many SU2 users export mesh from commercial softwares like icem as I'm doing for my research

I exported file in .cgns format. But, I always have error in installing cgnstools (l want the ability to manipulating my cgns file), been working on this for days. I looked for cgns documentation and searched it but cannot find solution! Here's what I'm doing:

I'm executing following commands (with root privileges) (OS: Mint 17 and RHEL 6, if that has any effect!):

cd cgnslib_3.1.4/src/
./configure --enable-cgnstools
make
make install

This gives me error in "make" step itself:
----------------------------------------------------------------------------------------------------------------------
----- cgnsview -----
make[2]: Entering directory `/home/chintan/Documents/cgnslib_3.1.4/src/cgnstools/cgnsview'
cc -O2 -I/home/chintan/Documents/cgnslib_3.1.4/src -c cgiowish.c

make: [cgnstools] Error 2 (ignored)

I installed tcl/tk package,too. But that didn't help. Is there anything that I'm missing?

Hello,

I think you should either make sure the tk.h is in the same folder as the source file it is trying to compile, or add the folder where your tk.h is in to your PATH variable:

export PATH=$PATH:'/dir/to/tk/script/'

I hope this helps!

Hi Jeffrey, thanks for reply. I tried that but it didn't work. I also tried copying all "*.h" files to my source code folder but that didn't work either! It still gives me same error! What else can be done?

Also, as an alternative, I was able to install cgns library without cgnstools. Based on SU2 documentation I guess SU2 can convert cgns to .su2 format and that doesn't need cgnstools for that and as .su2 is human readable I would be able to edit boundary conditions in .su2 mesh file. Is that right?

I have followed the following procedure to solve the CGNS problem:

Step 1: Installed CGNS library obtained from http://cgns.sourceforge.net/download.html

Step 2: Installation of SU2 : Instead of only "./configure" I have used " ./configure --with-CGNS-lib=/usr/local/lib --with-CGNS-include=/usr/local/include --enable-metis"

Step 3: Then went through usual procedures "make" and "make install"

Till now everything works fine. I hope this can help you. Thanks.

Thanks a lot Shainath. It was helpful.

I was able to compile cgns source code without cgnstools without any trouble. And I converted cgns mesh into su2 mesh. So, it solves my problem.

But if someone has successfully installed cgns tools, I would still like to know how.
