Hi everyone, I am having trouble building from source on Ubuntu 10.04. I have 8GB of RAM. Before this error I was getting an error about boost/irange.h not found. I downloaded the latest version of boost and placed that directory on graph-tool to fix this. Seemed to correct other errors but now I am getting the following: user@wuwcorp:~/graph-tool-2.2.24$ make make all-recursive make[1]: Entering directory `/home/user/graph-tool-2.2.24' Making all in src make[2]: Entering directory `/home/user/graph-tool-2.2.24/src' Making all in graph make[3]: Entering directory `/home/user/graph-tool-2.2.24/src/graph' Making all in centrality make[4]: Entering directory `/home/user/graph-tool-2.2.24/src/graph/centrality' CXX graph_pagerank.lo cc1plus: malloc.c:3551: munmap_chunk: Assertion `ret == 0' failed.
