Spot's porting CHALLENGE!

I released yet another update to my popular 'Spot's Porting for Dummies' today.
To celebrate that, I thought of a way to have some fun.

Let's have a challenge! A new version of a cool top down multiplayer shooter got released
recently. It's a quite easy port, it only involves some unix path fixing, and some changes to the makefile.

The first newbie porter that uploads version 0.4 will get an honorary mention in the next version of the guide! ;) I ported version 0.3, use the replace function on OS4Depot.

Here's the sources; http://icculus.org/cdogs-sdl/files/cdogs-sdl-current.tar.bz2
Here's the datafiles; http://icculus.org/cdogs-sdl/files/cdogs-data-current.tar.bz2

Non-first-porters, please leave this one for a first timer!

First timers, use the guide, and HAVE FUN! Let's get CDOGS 0.4 ported!

@spotUP

dl and compiled!!! changed/added a few #ifdef __amigaos4__, but my main porblem is with SDLmixer, i think i have it not right installed (SDLmixer) please where to find it?

Compied using OS4 GCC 4.0.3 it works, but music is wrong played

wanna me to submit herre the changes?? just a couple of lines

@jabirulo

I think the answer is in Spot's guide

In any event, it's on OS4Depot.

Chris

@jabirulo

good work. don't post your changes until you have uploaded your final version to os4depot/aminet.

what errors exactly?

try this version;
http://www.os4depot.net/share/development/library/sdl_mixer.lha

@jabirulo

If you're using the latest SDL_mixer from OS4Depot make sure you also install the latest SDL (v1.2.11) from:

http://www.rcdrummond.net/sdl/index.html

It is stated as a requirement in the readme.

@spotUP

i get linking errors, bilding .o doesn't show errors (-Wall shows ome unusued vars, & uninitializaed vars too, but no big problems)

Compiling with NOMIX it createst the binary without problems, i get the errros below when trying SDL_MIXER.

Will sdl_mixer from os4depor &rcdrummon web site and tell what happens. BYE

@jabirulo

Quote:
When linking against static libraries, the order in which you link them is important. You're linking against SDL and SDL_mixer in the wrong order. SDL_mixer uses functions from SDL, so you need to specify SDL_mixer first.

For example:

gcc obj1.o obj2.o obj3.o -o my.exe -lSDL_mixer -lsmpeg -lvorbisfile -lvorbis -logg -lSDL_image -lpng -ljpeg -lSDL -lz -lm

Cheers,
Rich

@spotUP

Wow, not easy for a dummy. A command line program would have been easier

@evilrich

you're right, learned that by tryng and error no more problems, sound now works, perfectly, will try to upload ASAP on os4depot

THX to all

@jabirulo

Would it be possible for you to share your makefile with those of us, that also have tried to solve the challenge, but failed bit time...

@Controller

erm, well i'll think about it...

and i changed some lines in config.h events.c files.c input.c sounds.c & cdogs.c
if you want i can send them to you via PM

Since Tabs are significant in makefiles, maybe you should try reposting with preformatting tags such as <pre> before the text and </pre> after it.

@spotUP

I still have some problem with my SDK (I believe it's not loaded properly, I need to check my Startup-Sequence)... I will try to look into it this weekend if I'm not too busy with gardening !...

OK thx, didn't know i had to use HTML tags

@jabirulo

Thanx for sharing and participating!
I love how this thread has evolved!
Good work on the port there!! I hope we'll see more from you.

I promise to give you the honorary mention in the next version of the holy guide ;)

And, to those of you who wasn't as quick as jabirulo, do you think this was a good idea?

Shall we do it again? If so, the next time i find something that is easilly ported, and this time i'll make sure it's really easy, i could start porting challenge #2 and post the link to the sources.

And if you guys run into problems, i promise to monitor the thread and do my best to help out!

@jabirulo

I suggest if you can you upload the Makefile somewhere and then link to it from here as that way there is no risk that the forum code breaks it by removing whitespace/changing tabs into spaces or whatever.

If that's not a possibility you could try [ code ] [ /code ] tags or maybe use the "code paste" function on utilitybase.com...

@spotUP

I'd love to get into this, but alas, I have no A1 :(

tiffers

@spotUP

yes please 2nd challlenge, so i can learn a bit more of porting stuff. Tried some other games, but too much .c/.cpp files and they compie OK but don't link still trying to port/understand how they can be compiled under OS4


@salas00

OK will try to put it on my web page ASAP, makefile and .c/.h i modified (thru #define __amigaos4__)

THX & BYE

@jabirulo

if you've made it as far as to the linking phase, you're practically in the goal already.
check my porting for dummies, copy/paste the libs in my sdl configure line, and copy them to your makefiles, that should do it, if not, try to move the libs around.
sometimes it helps to change it from 1.o 2.o 3.o lib.1 lib2.lib3 -o test.exe ... to lib.1 lib.2 lib.2 1.o 2.o 3.o -o test.exe ... dunno why it is like this.
But his should make your apps link.
If not, mail them to me and i'll have a look at them and send the fixed makefiles back to you to have a look at.

@spotUP

The reason the order of the linker libraries and object files is significant is that the one with the most dependencies on the other libraries has to be listed first so that the linker will know what to look for in the later object files and linker libraries.
