Makefile advice - compiling an old game from source

[LetHopeItsSnowing]

Hi,

I am looking for some advice and pointers... One of the games I loved in my youth was "Mayhem" on the Amiga, its a freeware multi player shooter and great fun. http://hol.abime.net/3853.

The game was ported to PC and open sourced a good while ago and I got it running on my windows PC https://github.com/devpack/mayhem.

Its written in C and the only hard requirement appears to be allegro, which is available on the Pi.

So before I started hacking up the Makefile https://github.com/devpack/mayhem/blob/master/Makefile (of which I have VERY little experience of doing) and trying to get it compile does anyone have any advice / pointers / experience?

Thanks

Martin

I took a quick look. Actually it's written in C++. This is enough to get it to build..

$ git clone https://github.com/devpack/mayhem
$ cd mayhem && rm -rf allegro442_include
$ sudo apt-get install liballegro4.4 liballegro4-dev

Modifiy these lines in 'Makefile', leave the rest unchanged:
CPP = g++
CC = gcc
LIBS = -lalleg
STUFF= -O0 -g -Werror -Wno-write-strings -Wno-deprecated-declarations
CXXFLAGS = $(CXXINCS) $(STUFF)
CFLAGS = $(INCS) $(STUFF)

$ make

If it crashes on you try 'gdb' and see if you get the same as me..

$gdb ./Mayhem2.exe
>r
Program received signal SIGSEGV, Segmentation fault.

Pray that you don't (my pi is headless and not running X). I can get as far as the initial logo under unbuntu but that's a virtual machine. In any case, expect to have to check the filenames 'cos there's a mixture of upper/lower case.

Thank you, that is really help... I will try later.

I have got it to compile and when run in X the splash screen appears and zooms in...

You dont get the menu up and it doesnt detect key presses, but now it compiles I can debug..

Thanks again.

I got it to work...

A couple of issues relating to case sensitive file names (as expected) and a couple of bugs in the original code which generated segmentation faults in linux (not expected and a lot harder to track down!).
