I am trying to compile graph-tool on a machine of mine (Ubuntu 16.04, boost 1.60.0 and gcc 5.4.0) . To do this I am using ./configure CXXFLAGS="-std=gnu++14 -Wno-unused-local-typedefs" PYTHON="/home/pmj27/anaconda2/bin/python2.7" --enable-openmp --with-boost=/home/pmj27/anaconda2 When importing graph_tool.all in python, however, I get an error message as follows: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/pmj27/anaconda2/lib/python2.7/site-packages/graph_tool/__init__.py", line 111, in <module> dl_import("from . import libgraph_tool_core as libcore") File "/home/pmj27/anaconda2/lib/python2.7/site-packages/graph_tool/dl_import.py", line 61, in dl_import exec(import_expr, local_dict, global_dict) File "<string>", line 1, in <module> ImportError: libicui18n.so.56: cannot open shared object file: No such file or directory Checking for the location of `libicui18n.so` (/home/pmj27/anaconda2/lib) I have tried ./configure CXXFLAGS="-std=gnu++14 -Wno-unused-local-typedefs" PYTHON="/home/pmj27/anaconda2/bin/python2.7" LDFLAGS="-L/home/pmj27/anaconda2/lib" --enable-openmp --with-boost=/home/pmj27/anaconda2 this however returns the same error. Checking `conda list` the icu version that is running is indeed only version 54.1 so I am not surprised that it cannot pick up version 56. I am wondering though why it is looking for version 56 in the first place. My suspicion is that this may be an anaconda issue introduced by some package but am not 100% sure. If it is an anaconda issue how would I go about tracking down which package is causing it to try and import libicui18n.so.56 so that I can see if there is a fix for it? -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...
