Hi all,

First of all, I’d like to warn that this estrange thing I’ve found in Paraview 5.0.1 + Linux binaries, I would just like to understand if this is something known already.

I downloaded from the downloads section the binaries package ParaView-5.0.1-Qt4-OpenGL2-MPI-Linux-64bit.tar.gz

I’ve found that libBDATReader.so + libBDATSeriesReader.so have dependencies on boost libraries:

[aurora@linux-dev-1 ParaView-5.0.1-Qt4-OpenGL2-MPI-Linux-64bit]$

ldd lib/paraview-5.0/libBDATReader.so | grep boost

```
libboost_thread.so.1.56.0 => not found
libboost_system.so.1.56.0 => not found

```

find ./ -name “_boost_”

(nothing found in the whole paraview package)

**The thing is that Paraview is working perfectly**

Then it seems that those two libraries were not used at all? Anyone knows why those libs had that broken dependency?

Since all the dependencies are packaged with paraview, `ldd` will not quite tell the truth here (it will only look for your system’s libraries).  
Try

```bash
LD_LIBRARY_PATH=`pwd`/lib ldd lib/paraview-5.0/libBDATReader.so

```

Also, your find command should be `find ./ -name "libboost*"`

BDATReader and friends are from the VortexFinder project. They’re plugins, so ParaView doesn’t care about them right away.

I’ll also note that this appears to be a 5.0 build. Since then, our packaging step has gotten a lot better about actually packaging all required libraries. Some plugins missing a library or two is not 100% surprising to me from the 5.0 era.

Thanks for your answers. I deleted them and everything keeps working smooth. Thx
