ADOM Sage for Ubuntu, and other distros

[Stathol]

[May 12, 2009] New version available -- Should compile on most systems, albeit with some warnings
[April 13, 2010] Hosting change. Sorry.

I spent a little time this weekend messing around with ADOM Sage from Ubuntu. Due to the age of the Sage code base, it will not compile on most modern systems, and the last official binaries have dependencies on deprecated runtime libraries that aren't present on most systems (and may be difficult to acquire for some).

I've updated the source code so that it will compile with modern versions of gcc, and built new binaries that link to more recent runtime libraries.

You will probably still get a warning about an ambiguous 'else' statement, but it seems harmless, and trying to figure out all those nested 'if's just made my head hurt. You're welcome to ferret that one out on your own, if it bothers you .

Additionally, your compiler may spew warnings about <ext/hash_map> being a deprecated header. I may get around to updating the code to work with the <unordered_map> library instead, but it requires compiling with a (draft) ISO C++ standard. That, in turn, will involve making a lot of other changes to the source in order to get it to compile under the stricter standards. I don't really know my way around gcc or the ISO C++ standards to know how/what all needs to be fixed, but I'll take a look at it and see what I can do. In the mean-time, this will still compile on most systems.

Pre-compiled Linux Binaries

adom-sage-0.9.1-2009-05-12.tar.gz

Required runtime packages: libstdc++6 , ncurses5

Instructions:

1. Untar.
2. Copy adom-sage and adom-sage.so to your ADOM directory.

Updated Source Code

Method one - download the updated source tarball:

adom-sage-0.9.1-2009-05-12-src.tar.gz


Method two - patch the original 0.9.1 source:

Original source tarball:
adom-sage-0.9.1-src.tar.gz (official 0.9.1 source tarball)
[Edit: looks like the original Sage site is down, perhaps for good. Here's an alternate location:]
adom-sage-0.9.1-src.tar.gz (archive.org cache)

adom-sage-0.9.1-2009-05-12.diff (unified .diff patch)

Unpack the 0.9.1 source. Place the .diff file in the Sage source folder and run:

patch < adom-sage-0.9.1-2009-05-12.diff

Build Instructions

Required developer libraries: libstdc++6, ncurses5

1. Run make.
2. Copy adom-sage and adom-sage.so to your ADOM directory.

Detailed Description of Patch/Changelog

Files affected: adom-sage.h, stl.h, io.cc, library.cc, sage-frontend.cc, spells.cc

Issues Addressed:

• Imported the std namespace into stl.h and sage-frontend.cc. This was preventing the code from compiling.
• Included <cstring> in adom-sage.h and adom-sage.cc. It's probably not necessary to put it on both places, in hindsight, but I was fixing errors in the sequence that they cropped up from gcc, so that's just how it worked out :P
• Updated the location of the hash_map library (to <ext/hash_map>) and imported the __gnu_cxx namespace in stl.h. This is necessary to compile the code on standard-compliant compilers.
• Fixed various casts from string literals to char *.
• Fixed a bad pointer conversion from MouseCookie to mmask_t. MouseCookie is now a type pun for mmask_t, and the cast can safely occur implicitly.
• Initialized some uninitialized variables in the get_key function of io.cc.
• Stripped an unused variable (char * padding) from StateCastSpell::vsprintf in spells.cc

(Note: Yes, I know importing namespaces into header files like that is bad. But the original adom-sage source doesn't appear to have been namespace-aware to begin with, so I'm not especially concerned about polluting namespaces. I'm sure there is a much more elegant solution to all this, but I'm primarily concerned with just getting it to compile.)


Running the Original 0.9.1 Binaries

If, for some reason, you would prefer to use the original (official) 0.9.1 binaries, you will probably run into an error about a missing library - libstdc++-libc6.2-2.so.3. This is a "libc compatibility" module from an old version of libstdc++6.

Ubuntu users (prior to Hardy) can install it with:

sudo apt-get install libstdc++2.10-glibc2.2

Ubuntu Hardy users will need to download and install it from the Gutsy repositories.

RedHat users can find it here.

Man, I never realized using Linux was so simple.

[Stathol]

Heh. Fair enough. But this really isn't a Linux problem, per se.

The problem is the age of the Sage source code and the pre-compiled binaries. Neither have been touched in 6 years, and Linux has made major progress in that time. To put it in perspective, Red Hat has released 12 major versions since the "official" binaries were compiled. This is kind of like trying to get an old Win98 program to run in Vista.

Long story short, the official binaries link against old, deprecated libraries that aren't usually even installed on modern distros, and the source code is not standard-compliant. It simply won't compile with modern versions of gcc and libstdc++, which are much less forgiving of these problems. A secondary issue is that the code is a bit sloppy in a few places (no offense). It's nothing major, but I figured that while I was in the mood to update the source for modern Linux distros, I might as well make it build clean.

And i thought mindcraft is hard to understand. Now i will go into oblivion meant for Microsoft users.

[Stathol]

Meh.

Fine, fine, fine. I'll make this dead simple for Linux. Here's an unofficial binary and source distribution (adom-sage-0.9.1-2008-11-17):

Edit: Nevermind, this is redundant now. See OP.

I think, the clock on your PC is some 2 days ahead of RWT (rest world time)

Hmmm...how so? You might be looking at the date of one the original source files. They happen to all be dated Nov. 20, 2002.

[vogonpoet]

well, there is a chace I will be making the change over to Linux at some point in not too distant future, so I for one appreciate your efforts Stathol. Nice one.

[Soirana]

Don't take my irony to deep. It was meant more for Linux, not your efforts.
Although i use Linux for one strict purpouse - as an autobooting system CD to extract windows passwords, which are believed to be protected by mine system admin.

Wow, thanks a lot for this. I've been trying for some time to get ADOM Sage to rn on my Eee PC - this solves everything.

Silfir, it may look complex, but that's because Stathol has included a lot of details that are unnecessary for most. All any normal person needs to do is download his updated source and run the makefile.
