On compiling examples of CGNS
2 Attachment(s)
Hi
I am working on installing CGNS on Ubuntu. Well, actually I am already done with installing it but the problem is about actually using it. I followed the guide I found from a personal blog which is like as below; (in case I did it in a wrong way) ================================================== ================================================== =============== 1. installing "cmake-gt-gui" from Ubuntu Software Center. 2. installing "libx11-dev", "libxmu-dev" from Synaptic Package Manager 3. installing "OpenGL"; * sudo apt-get install libg11-mesa-dev * sudo apt-get install libglul-mesa-dev * sudo apt-get install mesa-common-dev 4. installing "szip", "zlib", "HDF5", "tcl/tk"; 4.1 zlib - downloading "zlib-1.2.8" from http://zlib.net - unzip it * ./configure -prefix=/opt/hdf5-1.8.14 * make * make check * sudo make install 4.2 szip - downloading "szip-2.1" - unzip it * ./configure -prefix=/opt/hdf5-1.8.14 * make * make check * sudo make install 4.3 HDF5 - downloading "hdf5-1.8.14" - unzip it * ./configure -prefix=/opt/hdf5-1.8.14 --with-zlib=/opt/hdf5-1.8.14 --with-szip=/opt/hdf5-1.8.14 * make * make check * sudo make install % if C++ error occurs : * sudo apt-get install build-essential 4.4 tcl/tk - downloading "tcl8.6.4-src" & "tk8.6.4-src" - unzip them * ./configure -prefix=/opt/tcl8.6.4 * make * make check * sudo make install & * ./configure -prefix=/opt/tcl8.6.4 * make * make check * sudo make install 5. cmake * sudo cmake-gui - options are like figure 1 - configure & generate 6. make install(@ /home/kim/Downloads/build) * sudo make * sudo make install ================================================== ================================================== =============== This is what I did to intall CGNS on Ubuntu. I tried to use the library on an example(cgns_test.f90) but an error occures saying; "Error: Can't open included file 'cgnslib_f.h" I thought maybe I need to make a link of "cgnslib_f.h" in the directory in which "cgns_test.f90" is. then tons of errors occure like figure 2. I really don't know what to do. Can anyone help me? I am desperately waiting for any help. Thank you for reading. |
by the way, "cgns_test.f90" is like this;
program cgns_test
implicit none include 'cgnslib_f.h' integer :: i, j, k integer :: ni, nj, nk real, allocatable :: x(:,:,: ), y(:,:,: ), z(:,:,: ) ni=21 nj=17 nk=9 allocate(x(ni,nj,nk),y(ni,nj,nk),z(ni,nj,nk)) do k=1, nk do j=1, nj do i=1, ni x(i,j,k)=real(i-1) y(i,j,k)=real(j-1) z(i,j,k)=real(k-1) enddo enddo enddo write(6,'(''created simple 3-D grid points'')') call cg_open_f('grid.cgns',CG_MODE_WRITE,index_file,ier ) end program |
Hi,
I assume you didn't solve this yet. Did you add the path to the header file to the include path during compilation? See also the header comment of the file that you include. It says to use the module cgns from file cgns_f.F90 Regards, Michal |
@ Michal
Yes you are right:)
I solved the problem by adding the path as you said. Now I am facing another problem..:( Anyway thanks for your reply!:D |
Use cmake if possible
It is me again,
let me just use this thread to encourage anyone starting with CGNS to use CMake if only possible. It will save you a lot of time and nerves, while trying to set correct include and linking paths. Here is my test project with CGNS used as a subproject: Code:
> tree -L 1 . Code:
> cat CMakeLists.txt Code:
> cat cgns_test.f90 Code:
cmake /path/to/Source && make && ./CGNS_test |
