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 processes are 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 want to plot
and give 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. Thank you.
