iris 3d issue

dciris · Post by **dciris** » Thu Feb 06, 2003 4:01 pm

When trying to compile samples boxed with Iris I get this type of error statement and I can't figure it out its messing me up?

/usr/local/dc/sh-elf/lib/gcc-lib/sh-elf/3.0.3/../../../../sh-elf/bin/ld:
cannot
find -ldcutils
collect2: ld returned 1 exit status
make: *** [anim_iris.elf] Error 1

Ps: The Kos environment compiles nicely but my elfs are double the size of the ones boxed with the samples? does any one know why?

Thanks to anyone taking the time to answer I am very grateful

From the makefile (should look something like this)

$(TARGET): $(OBJS)

$(KOS_CC) $(KOS_CFLAGS) $(KOS_LDFLAGS) -o $(TARGET) $(KOS_START) \
$(OBJS) $(OBJEXTRA) -L$(KOS_BASE)/lib -lkallisti -lm -lgcc -ldcutils

Remove the bolded statement it should work I dont think the Iris engine uses it but I may be wrong. I think it is just standard makefile for KOS

Man thanks a million that has baffled me for a real long time and now I can finally compile!!!!!!!!!!Sooo Happy

On another note
You wouldn't by any chance know why .elfs are created double their size I have no iris proof but the sample I compiled (anim) was close to 2 megs I don't know if thats regular or what but other samples with original elfs complie to double the original size

P.S. Thanks again

Thats true all you have to do to get it to run on dc is go

sh-elf-objcopy -O binary <your.elf> <yournew.bin>

Then burn it and load it up should work fine as long as your have everything that is needed on the disc

Also make sure to set your path to

PATH=/usr/local/dc/sh-elf/bin/:$PATH

That is where I installed my sh compilers change accordingly later glad I could help

I got everything running on dc via a serial cable but the actual files fully compiled by me are always double the size of the ones boxed with the source...I don't get it

compiler setting matter for bin sizes thats why

-o1 for a smaller bin then -o3 etc and other things make the bin larger

-oo can make it smaller etc again thats all it is

turn it into a bin it be the same size then you must not have strip on

Yet again you guys hook it up thanks very much...

I think your elfs are huge because they are not stripped of symbols.

If you load the elf in a gex-editor eg KDE's HexEdit, you'll be able to see function names etc.

To remove these symbols, type "sh-elf-strip" [filename.elf] (If you built your environment using target=sh-elf)

you could also run "make dist" which strips the symbols for you.

Man thanks for the post its been a while since I got to the forum...
But now that I'm compiling the size of my .elf is becoming more and more of a problem I'm gonna look into what you said. Is "make-dist" a command you use while in the environment? I know I know I should just tryit but I figured I'd ask in case when I do try it it gives me an error thanks very much I will now pursue my mission of smaller elf sizes

nymus · Post by **nymus** » Mon Feb 24, 2003 4:16 pm

"make-dist" is an option in the makefile. It's just a common name used in place of "sh-elf-strip [filename]"

Just open the makefile in a text editor and see for yourself

Its been a very long time since my last post thanks a million for all the previous help to annoying questions...Currently I am still having trouble with huge .elf file sizes I can't for the life of me figure how to minimize their size by using the make file. This is the make file I am currently using I would really appreciate any help if possible. (still looking into a hex editor)

Guys I'm sorry for asking some of the most un interesting/annoying questions ever

Thanks a million though for baring with me FINALLY I have figured out with much help of course that after your .elf is compiled one can simply use (make dist) to optimize the files size. So happy this works...Sorry for all the reposts and annoyingness.... Yet I HAVE ANOTHER IRIS 3D ISSUE... Recently I been trying to incorperate .ogg files into my program but I have traced that the reason this does not work is that the IRIS make file is different than the KOS makefile housed with the hello ogg example file. I have spent a lot of hours trying to figure out how to modify Iris makefile I am using to allow the .ogg file commands to compile I will post both makefiles in hope someone can help me out thanks guys...

Can I ask what you are making?

dciris · Post by **dciris** » Wed May 21, 2003 8:17 pm

I am trying to make a demo game with a title screen, player select and some sort of game play I would like to use the .ogg for a consitent loop in the player select.

Oh okay, tell us if it works.

You could try asking for help in the iris3d forum.
