Mk build system?

[CJNyfalt]

I am looking to learn how the mk build system used by vanilla and FA works. Can anyone point me in the right direction?

Pretty much it's just 'look at the existing makefiles'. It's fairly simple to use, relative to most other autotools-based build systems—which is one of the reasons I ported V to it. My guess is FA uses it for the same reason.

You know I need more info than that to try it out.
- Which files are the config files that are edited?
- Where do I get the files that are used to run the build system and which ones are they?
- What do they replace compared to standard autotools?
- Where do I find documentation?
- What commands are run to set up the build system?

Sadly, the master reference for this build system was taken offline within a couple of months of V adopting it. There wasn't enough left for me to make an intelligible local mirror.

It is optimized for manual maintenance, and relies heavily on gmake extensions. Follow the include directives and all shall become clear.

Your problem is that http://www.atheme.org/ has pulled virtually all references to their Objective Make build system from the Internet. I think Angband is the last holdout on accurate documentation. (Not even the project infighting notes over this are making Google now.)

configure.ac is where your standard configure script stuff goes. buildsys.mk.in and extras.mk.in is where environment variables go.

configure.ac, Makefile, buildsys.mk.in, extras.mk.in — they are included with Angband.

- What do they replace compared to standard autotools?

This is standard autotools; the difference lies in how everything is put together. All the automake rubbish goes into configure.ac along with autoconf's stuff; additionally, the buildsystem itself is in one place and one place only: buildsys.mk.in (which is transmogrified into buildsys.mk once ./configure is run). This means you only need to have autotools substitute three files: config.h, buildsys.mk.in, and extras.mk.in.

- Where do I find documentation?

So far as I know, there isn't any aside from the relevant files themselves (Makefile, configure.ac, buildsys.mk.in, autoconf.mk.in).

- What commands are run to set up the build system?

• sh autogen.sh # only if you're working with a development snapshot which doesn't have a ./configure script already.
• ./configure ...
• make
• make install

Additionally, the bare buildsystem may be obtained, with comments where appropriate, via the original author's mercurial repository.

Thanks that will help, and at least I will know enough to ask the right questions if I run into trouble.

I did study the files a bit, a now I wonder if it is true that the build system does not calculate dependencies at all? That was at least the impression I got.

The version in Hg does—if Angband's doesn't, blame the devteam.
