Hi,
I'm getting the following error when I try to compile the git version. I
only get the error when I pass --enable-openmp to configure and then run
make. Here's the error:
graph_hits.cc:75:44: instantiated from here
graph_hits.hh:67:21: error: 'std::norm' is not a variable in clause
'reduction'
I think it's something to do with openmp. I'm using gcc version 4.7 on
Ubuntu 12.04. I have all the dependencies (and optionals) installed from the
GraphToolDownload page. Any ideas? Thanks!

Hi list, hi Tiago,
First thank you for graph tool, that's a great package.
I run in a very strange problem when reloading a xml graph file with an
'internalized' PropertyMap.
the minimum script does the following:
* test1: create, internalize the PropertyMap pos1, save the graph in xml
* test2: load the graph from xml, read the internalized PropertyMap pos2
Depending whether the two tests are ran in separate processes are in the
same process, the two Propertymaps will not have the same values:
test1 and 2 in the same process:
pos1 == pos2
test1 and test2 in different processes
pos1 != pos2

I finalty managed to compile:
For info, I removed the layout part to avoid the memory problem, by
removing mentions of it in the following files:
modified: configure.ac
modified: doc/draw.rst
modified: src/graph/Makefile.am
