Hi, I have some problems in compiling these two utilities. I've succesfully downloaded the irrtoolset-20040308-1.patch (thank you glen!) and I've applied it so that I can compile with gcc3.3.1. But I can't compile, with the general Makefile, prpath and prtraceroute, so I used theirs Makefile but I get some errors. They are type-conversion errors, and so I can't resolve them without great truble by understanding the entire code... For example, in compiling prtraceroute I get "cannot convert `const MPPrefixRanges*' to `const PrefixRanges*' in assignment" in bgproute.cc line 1086, and of course compiler is right! Someone changed return type of the method "expandRSSet" in irr.hh... and so on... I tried to solve this and the other following 3 or 4 errors by casting (they aren't much more), but while it compiles correctly, it does not run correctly: I launched prtraceroute www.google.it and I got 1 * 2 * 3 * .... etc. etc. If I use the simpler traceroute I got the right gateways and the right route, so I think that it's a buggy program or, probably, I cant' cast everything I want... I hope someone could help me, 'cause I desperatly need a program with the characteristics of prtraceroute and prpath for a project for a school course. Thank you for the attention and sorry for my english, I'm italian. bye! Emanuele
