Hi,

I am trying to run the help function available in paraview, but I get the error message "Failed to launch Qt installer". Is there a way to fix this problem?

I use the command paraFoam to run paraview program. I have the linux 32-bit parafoam ver 1.6, and paraview ver 3.6.1.


Thanks in advance for your help.

Greetings felik9,

There are two things necessary for Help to work in the pre-built ParaView:

1. install Qt4 Assistant in your Linux installation; the package could be called "qt4dev-tools" or something like that, depending on what Linux distribution you are using.
2. you'll need to fix the path for the help files that is built-in the file pqClientDocFinder.txt:

   cd $WM_THIRD_PARTY_DIR/paraview-3.6.1/platforms/linuxGcc/bin
   mv pqClientDocFinder.txt pqClientDocFinder_orig.txt
   cat pqClientDocFinder_orig.txt | sed 's/\/home\/dm2\/henry\/OpenFOAM/'${HOME}/OpenFOAM'/' > ./pqClientDocFinder.txt

Best regards,
Bruno

Hi Bruno,

I followed your instructions. When I entered the third command, I get the following message.

cat pqClientDocFinder_orig.txt | sed 's/\/home\/dm2\/henry\/OpenFOAM/'${HOME}/OpenFOAM'/' > ./pqClientDocFinder.txt
sed: -e expression #1, char 33: unknown option to `s'

I ignored this message, and then typed the ". $HOME/.bashrc" command before running paraFoam. Now I get the following error message when I click the help option.

Help Error:
Couldn't find pqClient.adp.
Try setting the PARAVIEW_HELP environment variable which points to that file


I don't understand what this means. What should I do?

Thanks,

Felik9

Hi Felik9,

Sorry about that, I should have tested the command first Try this:

cd $WM_THIRD_PARTY_DIR/paraview-3.6.1/platforms/linuxGcc/bin
cat pqClientDocFinder_orig.txt | sed 's=\/home\/dm2\/henry\/OpenFOAM='${HOME}/OpenFOAM'=' > ./pqClientDocFinder.txt

Basically, when using sed, the slash "/" character is the usual character for separating the before and after expressions; but in this case, we need to change paths that rely heavily in the slash, so it's best to change the usual slash to another character, in this case the equality "=" character

Best regards,
Bruno

Thanks for your help, Bruno!

It's working now, but the Help that I get is for Paraview ver. 3.5 not 3.6.1. Shouldn't there be a Help for version 3.6.1?

what the..? I didn't notice that before! Probably the ParaView developers forgot to update the version in the help file
