Cannot create run following jumpkind Ijk_SigFPE_IntOvf

error：angr.analyses.cfg | AngrError Cannot create run following jumpkind Ijk_SigFPE_IntOvf when creating SimRun at 0x40a9dc
what should i do ? thanks

That is a jump that will only be triggered when an floating point instruction causes an integer overflow. You can safely ignore the message when building the CFG.

after I loaded a binary project, i use the "print cfg.graph" instruction, why nothing is been output?

[ltfish]

CFG.graph is a networkx.DiGraph, and it's normal for it to print out nothing as the default repr string. Please take a look at cfg.graph.edges() for edges and cfg.graph.nodes() for nodes.

You may want to use angr-management (our official GUI) to visualize the CFG, which will require some intensive Python and enaml background. Alternatively, you can try this out: https://github.com/axt/angr-utils

Also, please submit new angr-related issues under angr project - this is angr-doc.

Asking on #angr on freenode.net might also get slightly quicker results to questions like this.
