Knights Discussion / Re: Dagger hotkey
Last post by d.healey - August 13, 2017, 12:36:24 PMYeah that's fair enough. Well I don't mind having a tinker with it, it's been a long time since I worked in C++ though and never on a largish project like Knights so a few pointers are appreciated.
I can see there are a number of a keyboard controller files in the main folder - I guess this is where I should be looking?

g++ --version
Update: I uninstalled g++, updated my repos, reinstalled and got version 5.4.1. Did make clean, sudo make install, and now it works :)
Thanks for your patience and help.

Last post by Stephen - August 13, 2017, 09:41:36 AMI guess, but the problem is, I don't really have much time to develop the game nowadays. I will fix any major bugs or crashes if they come up, but I'm not really adding new features at the moment.
I would like to get back into development at some point but right now I don't have a lot of spare time unfortunately.
In the meantime the game is open source so if anyone wants to have a go at adding new stuff then they are more than welcome to do so, and I will assist in whatever way I can.

Last post by Stephen - August 12, 2017, 10:27:34 PMAlso, here is a screenshot from gdb of the disassembly of the RStream::Initialize function.
http://www.knightsgame.org.uk/disassembly.png
Dave's executable is on the left and mine is on the right.
I'm not sure why, but there are some differences... for example, my version reserves more stack space (0x58 bytes as opposed to 0x30) and mine is doing something with the %fs register which I don't quite understand.
I think most of the code that we're seeing here has actually been inlined from bfs::canonical so it is possible that Dave is picking up a rogue boost header file from somewhere. Alternatively, it might be some difference in compiler version or compiler flags perhaps?
It's a bit of a mystery at the moment!
My compiler version is g++ 5.4.0.

Last post by Stephen - August 12, 2017, 09:51:13 PMHmm... good question...
Maybe try "find / -name boost 2>/dev/null" and see what it prints out.
On my clean linux install it gives
/usr/include/boost
/usr/include/boost/chrono/typeof/boost
...which indicates there is only one set of boost headers, in /usr/include/boost.

Last post by d.healey - August 12, 2017, 08:08:28 PMQuote from: Stephen on August 12, 2017, 04:46:17 PMd.healey please could you look in /usr/include/boost/version.hpp (or wherever you have the boost headers installed) and see what it says for BOOST_LIB_VERSION. It's possible you might have boost installed in two places or something like that, and it's picking up the wrong version of the headers during the compile.
This is what it shows in that file on my system - #define BOOST_LIB_VERSION "1_58"
Is there a way to check if there are multiple versions installed?

Last post by Stephen - August 12, 2017, 04:46:17 PMI did some investigating.
First I reproduced Impassive's result -- I did a clean Linux Mint install and built Knights and there was no crash.
Then I downloaded d.healey's executable and ran it, and I got a segmentation fault.
From reading what Impassive wrote it does indeed sound as though the stack is being corrupted across one of the boost library calls.
The only thing I can think of that might cause this is a mismatch between Boost header and library (.so) versions on d.healey's system.
I can see that the knights exe supplied by d.healey links against boost 1.58 (you can see this by running "objdump -p knights" and looking at the .so file versions). I can't see which version of the boost headers he used though.
