[gradsusr] Error with sys command

[Davide Sacchetti]

when you invoke convert from grads you export grads environment to imagemagick processes:
try adding 'unset LD_LIBRARY_PATH' at the beggining of convertPNG.sh
Hoping it helps

 Oggetto:   [gradsusr] Error with sys command 

Hi GrADS users and developeres ! 
 
I create some PNG plots succesfully. 
I wish to change the colors palette. 
I invoke convert (imagemagik) via the sys command from a script. 
 
convert is installed and work fine directly from a Bash or Python script 
from Debian Bulleyes. 
 
cmd = "./convertPNG.sh "%pngFile 
say cmd 
sys (cmd) 
 
I get this error : 
 
./convertPNG.sh ./img/aromeOM/20211016/00/antilles_uv_cape_rh2m_00.png 
convert: 
/opt/opengrads/opengrads-2.2.1.oga.1/Linux/Versions/2.2.1.oga.1/x86_64/gex/libstdc++.so.6: 
version `CXXABI_1.3.8' not found (required by 
/lib/x86_64-linux-gnu/libicuuc.so.67) 
Syntax Error 
  Error occurred on line 1 
  In file ./img/aromeOM/20211016/00/antilles_uv_cape_rh2m_00.png 
 
 
I tried this : 
 
'!./convertPNG.sh '%pngFile 
 
I get this similar error : 
 
convert: 
/opt/opengrads/opengrads-2.2.1.oga.1/Linux/Versions/2.2.1.oga.1/x86_64/gex/libstdc++.so.6: 
version `CXXABI_1.3.8' not found (required by 
/lib/x86_64-linux-gnu/libicuuc.so.67) 
 
 
convertPNG.sh : 
 
if [ -f "$1" ]; then 
 convert -type palette -colors 255 "$1" png8:"$1" 
fi 
exit 0 
 
Is it only the available version of libstdc++ that is at issue? 
 
Any help is appreciated to solve it, 
steph
