Dear Sir/Madam,
I have installed ccplot in Ubuntu 18.04 LTS app
on my PC (Windows 10). For the installation process, I followed the user
guide which is available on the website (https://ccplot.org/download/). The
steps I followed for the installation process is given below:
1. To install the required libraries and ccplot:
sudo apt install --no-install-recommends python3 python3-dev gcc
python3-distutils cython3 libhdf4-dev libhdfeos-dev python3-pil
python3-numpy python3-matplotlib python3-mpltoolkits.basemap
ttf-bitstream-vera
2.Build and install ccplot:
tar xzf ccplot-1.5.6.tar.gz
cd ccplot-1.5.6 sudo python3 setup.py install
After that to check the version I simply run the 'ccplot -V' command to
print the version of the ccplot and the output came is in the following:
ccplot 1.5.6
Third-party libraries:
matplotlib 2.1.1
basemap 1.1.0

Now after that I wanted to make a plot from a hdf file of CALIPSO data
using ccplot as per the instruction given in the Chapter 6 of 'Visualising
Data from CloudSat and CALIPSO Satellites'. I have made a directory named
'HDF' inside the folder 'ccplot-1.5.6.' where I put the hdf files I want to
plot.
1. First I gave the command to know the information about the file
ccplot -i
HDF/CAL_LID_L2_05kmCLay-Standard-V4-20.2006-06-13T07-20-12ZD_Subset.hdf
and the output came
Type: CALIPSO
Subtype: profile
Time: 2006-06-13 07:44:32, 2006-06-13 07:47:00
Height: -1815m, 39855m
nray: 200
nbin: 583
Longitude: 84.06E, 86.27E
Latitude: 21.55N, 30.46N
So up to this step, I think this is working fine. But when I wanted to plot
and gave the command below it throws an error!
ccplot -o calipso1.png cmap/calipso-backscatter.cmap calipso532-layer
/HDF/CAL_LID_L2_05kmCLay-Standard-V4-20.2006-06-13T07-20-12ZD_Subset.hdf
ccplot: calipso532-layer: HDF: SDstart failed: b'Bad file name on open'.
Does it mean ccplot is not installed properly? Can anyone tell me why this
is happening? And how to solve this problem? I am very new to this software
tool and any help on this is very much appreciable. For your convenience,
I am attaching the sample file and also the lines that came during the
installation of the ccplot to check if the ccplot is installed properly or
not. Please find the attachment. Thank you.
