ImportError: libboost_iostreams.so.1.61.0: cannot open shared object file: No such file or directory

Question

I am using Anaconda as my main python distribution (though also have the system's default python installed) so have to compile graph-tool from source to get it to work with Anaconda.

I am using Ubuntu 14.04 so also have to compile boost from source to be able to use the full functionality of graph-tool as the boost-coroutine library is currently only compiled as a static library (https://bugs.launchpad.net/ubuntu/+source/boost1.54/+bug/1529289).

I have done so and they have both installed without any error messages, however, when then importing graph-tool in python using from graph_tool.all import * I get the error message ImportError: libboost_iostreams.so.1.61.0: cannot open shared object file: No such file or directory.

How could I go about solving that problem/what is this caused by?

Answer 1

Seems you have wrong boost package version installed by conda

1. List installed conda boost package in current environment conda list | grep boost, you can see wrong version (not 1.61.0)
2. Search required version anaconda search -t conda boost | grep 1.61.0
3. Install correct version with same name conda install boost -c CHANNEL_NAME

In my case I also have conflicts with this message:

Linking packages ... CondaOSError: OS error: failed to link (src='/home/user/anaconda3/pkgs/icu-54.1-0/lib/icu/pkgdata.inc', dst='/home/user/anaconda3/envs/py3_graph/lib/icu/pkgdata.inc', type=3, error=FileExistsError(17, 'File exists'))

Removing /home/user/anaconda3/envs/py3_graph/lib/icu folder helps me
