Irrlicht 1.3.1 Autotools

anylo · Post by **anylo** » Thu Sep 27, 2007 9:47 pm

Here's pre-pre-alpha (a.k.a. "laugh release") of the Irrlicht 1.3.1. Only core files are in this dist.

http://www.kolumbus.fi/anssi.ylonen/irr ... 3.1.tar.gz

Check wiki for required libraries, enable shared lib with

Code: Select all

./configure --enable-shared

install with

Code: Select all

sudo make install

and uninstall with

Code: Select all

sudo make uninstall

etc.

Bug reports etc. into this thread. I'll also try to add 01.HelloWorld example later tomorrow.

You don't know Autotools? Shame on you.

EDIT:
For a while link gave version which did not compile. It should be fixed now.

There's a "small" bug in that tarball. Library is not linked against any required libries (GL, png, jpeg, etc).

I'll make new version later today.

OK, here's pre-alpha (still "laugh version" status)

http://www.kolumbus.fi/anssi.ylonen/irr ... pha.tar.gz

Configure, compile and install.

Here's also small example how to use a static version of the library:

http://www.kolumbus.fi/anssi.ylonen/irr ... 0.0.tar.gz

Code: Select all

./configure --with-Irrlicht=/usr/local && make

Could you provide just the files neeed for autoconf usage? It's pretty much work for nothing to extract them from the tarball.
Those files also look quite weird and hardly maintainable. What's required to update manually when, e.g., changing this stuff from 1.3.1 to latest SVN version of Irrlicht?

RTFM!

Ok, it's much easier than you expect. Core of everything is configure.ac (previously it was called configure.in). Version numbers, library depencies, flags etc. are in there. Then there's these Makefile.am files in each directory. Those are used to generate Makefile.in files, which are used to generate Makefiles. Sounds more complicated that it really is. Here's "skeleton" of the previous example:

http://www.kolumbus.fi/anssi.ylonen/irr ... ton.tar.gz

Code: Select all

tar xzvf irrexample-1.0.0-skeleton.tar.gz
cd irrexample-1.0.0-skeleton
autoreconf --verbose --force --install 
./configure --with-Irrlicht=/usr/local
make

Autoreconf does the real magic (it's basically autoconf, aclocal and automake put in together, so there's no need to use those).

Adding those into HEAD svn is just copying those previously mentioned files into their correct locations and checking if there's any (there is) changes in the file lists (take a look into that Irrlicht 1.3.1 package and check /include/Makefile.am and /source/Irrlicht/Makefile.am).

Well, there's much more to make real use of autoconf tools. For example changing includes to make use of config.h. We need to add those --enable-something switches, make default settings, etc. The cross-compilation needs extra work I guess, right now the Makefile works also for win32 builds under Linux. and so on...

Easiest way is to include config.h into IrrCompileConfig.h and change it so that if something is already defined in config.h then it won't be defined again. And if there's no config.h at all (building in Windows or something like that) then the original settings in IrrCompileConfig.h are used.

EDIT:
And remember, I've released pre-alpha version. Everything should be much better in alpha release.

Implemented support for doxygen.

Code: Select all

./configure --enable-doxygen-pdf
make doxygen-doc

will create nice pdf of Irrlich API (~950 pages). And of course html-version.

Alpha is released when it's ready.

Using local copy of zlib/jpeg/png libraries is not implemented. Yet. I tested this version quite slightly, so there's probably some bugs. I really hope that you test this and give me some information is this working or not. Hopefully it is.

EDIT:
make doxygen-doc

Further testing revealed that support for X11 and Burning's video device flags were mixed.

And you cannot compile with --enable-pedantic:
