Compilation Error (OpenMP)
by cc 06 Oct '12

06 Oct '12

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! -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com… Sent from the Main discussion list for the graph-tool project mailing list archive at Nabble.com.

Strange save / load_graph behaviour
by Guillaume 04 Oct '12

04 Oct '12

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 -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com… Sent from the Main discussion list for the graph-tool project mailing list archive at Nabble.com.

[solved] virtual memory exhausted

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 Guillaume Le 04/10/2012 12:09, Tiago Peixoto [via Main discussion list for the graph-tool project] a écrit : > On 10/04/2012 11:51 AM, Guillaume Gay wrote: > > Hi Tiago, hi list, > > > > Trying to compile from the github repo, I run into this error with > make: > > > > make[4]: entrant dans le répertoire « > /home/guillaume/Python/src/graph-tool/src/graph/layout » > > CXX graph_sfdp.lo > > virtual memory exhausted: Cannot allocate memory > > make[4]: *** [graph_sfdp.lo] Erreur 1 > > It takes quite a bit of memory to compile graph-tool, due to the heavy > use of template metaprogramming.
