Allegro

[namco]

Apologies for the new thread.

Since I'm got my main pc back I've decided to have a fresh look at compiling zombiepox.

This is what output my makefile gives:

Do I need to go back through the library and fix stuff or have I just compiled it wrongly.

Just in case that I have compiled wrongly I'll also provide the makefile below:

CODE

PROG_NAME = zombiepox
OBJS = main.o CItem.o CTile.o CMap.o CActor.o hisc.o soundbox.o
CROSS_COMPILE = C:/devkitGP2X/bin/arm-linux-

CC = $(CROSS_COMPILE)gcc
CXX = $(CROSS_COMPILE)g++
STRIP = $(CROSS_COMPILE)strip
CLEANUP = rm -f $(ALL_TARGETS) *.o *~
GPECOMP = gpecomp $(PROG_NAME).gpi $(PROG_NAME).gpe

CFLAGS=`$(SDL_BASE) --cflags` -O2 -Wall -Werror
CXXFLAGS=`$(SDL_BASE) --cflags` -O2 -Wall -Werror
LIBS=`$(SDL_BASE) --libs`

TARGET=$(PROG_NAME).gpe
SDLTEST_OBJS = $(OBJS)

all : $(TARGET)

$(TARGET)(SDLTEST_OBJS)

$(STRIP) $(TARGET)

$(CLEANUP)



Thanks for any help.

 

[namco]

Does no one know??

 

[Parkydr]

Is 'C:/devkitGP2X/bin/gp2x-allegro-config --cflags' returning the right path?

 

[kevcal]

Hehe.. impatient?

Yeah, I'd say gp2x-allegro-config --cflags isn't returning the right path..
Under the returned path you would have (for example)
allegro/platform/alplatf.h

eg mine returns -I/opt/gp2x/include

You also have a weird mixture of slashes and backslashes..? Is this normal.. something to do with developing on windows??
eg "C:\gp2xallegro-0.3\include\/allegro/inline/system.inl"

 

[namco]

Thanks guys.

Sorry, I've been promising zombiepox for the past 6 months (on and off) and everytime I go back I keep getting damn errors.

Right, the returning path...this'll be that prefix I had to change in the config file?

QUOTE

Yeah I'm deving on windows so I'm assumming it's that. I do have Qemu with Slackware 11.0 set up, just in case

 

[kevcal]

Just run
C:/devkitGP2X/bin/gp2x-allegro-config --cflags
in a command prompt and see what's returned..
then check that path is correct.

Sorry, I don't dev in windows - too much 'in the way'

 

[namco]

Um, doesn't like that...however what I did do was to re write certain include files to point to the right area. For example:

C:\gp2xallegro-0.3\include\/allegro/internal/alconfig.h:36:44: error: allegro/platform/alplatf.h: No such file or directory

was re-edited so it now pointed at:
C:\gp2xallegro-0.3\include\allegro\platform\alplatf.h

that seemed to have done the trick.

However I'm now at my last error which I'm a little stuck on. After running make i now get:

QUOTE

Here is ISortable.h:

double m_x, m_y;

};


class ByYPos {
public:
bool operator()(ISortable *a, ISortable *b) {
return a->y() < b->y();
}
};



#endif



Thanks again!

 

[Parkydr]

Add 'virtual ~ISortable()'

It's warning you because this is a potential memory leak.

If you have a ISortable pointer pointing to a subclass of ISortable and delete the point, the destructor of the subclass will not be called if the destructor isn't virtual.

It's generally a good idea to make all destructors virtual to help avoid memory leaks.

 

[namco]

Did that which it seemed to be happy with, then it was doing the whole no rule to make target xxx needed by yyyy thing.

started again with their makefile and got this:

c:\devkitgp2x\bin\..\lib\gcc\arm-linux\4.0.2\..\..\..\..\arm-linux\bin\ld.exe: c
annot find -lalleg

 

[Parkydr]

Is 'C:/devkitGP2X/bin/gp2x-allegro-config --libs' returning the right path?

 

[kevcal]

You really need to sort out your 'gp2x-allegro-config' - hard coding paths into the makefile and/or your code isn't the preferable method.
The last warning you had probably implies the same problem - ie soulds like it can't find 'gp2x-allegro-config' ; borne out by the fact you couldn't run it from the command line.
I think you ought to sort that out first before you mess around any more with the makefile and source (apart from that destructor problem)?
Your last error implies it can't find the static lib for allegro.. ie a -L<path to lib> option to the linker.
Again, you could easily fix this by editing the makefile, but you're avoiding the basic problem.
Find on your system where 'gp2x-allegro-config' is and sort out the path to that in your makefile and undo your explicit paths in your header & source files.
Then tell us what it returns with --cflags and --libs options if it still doesn't build.

EDIT:
I'm also a bit confused why you use 'SDL_BASE' as a define in the makefile when using ALLEGRO, but that's not a major issue.

Sorry for cheating

It does find gp2x-allegro-config but complains saying that its not recognised as a program/batch file/internal or external command

As for the makefile, that was me using someone elses and modifying it. After getting the:

so I used this instead:

Which was their original and one that I modified.

Sorry about being so swappy. I'm just starting to get to get the hang of makefiles.

 

[kevcal]

Sorry for cheating
Heh - we all do it

It does find gp2x-allegro-config but complains saying that its not recognised as a program/batch file/internal or external command
Mmmm.. sounds like a windows thing.. Maybe Parkydr knows more what the problem is - do you use cygwin on windows???

Sorry about being so swappy. I'm just starting to get to get the hang of makefiles.
Makefiles (and vi) are great - it used to be so simple 20 years ago - then linux exploded onto the scene and there are all means of makefiles and configure scripts and GPL and SVN and and stuff...

Well you could go back to your makefile and add -L<path to lib> ...

 

[namco]

Not sure, I know that if I type "ls" into command prompt i get the linux version of "dir". And looking I have Msys installed, so that could be it.

After installing Slackware 11 on Qemu, I enjoyed playing with vim, just meant I didn't have to remember things like :wq etc etc

 

[kevcal]

Can't help you with your setup - have you tired implicitly using -

CODE
PROG_NAME = zombiepox
OBJS = main.o CItem.o CTile.o CMap.o CActor.o hisc.o soundbox.o
CROSS_COMPILE = C:/devkitGP2X/bin/arm-linux-
SDL_BASE = -IC:\gp2xallegro-0.3\include
LDFLAGS = -static

CC = $(CROSS_COMPILE)gcc
CXX = $(CROSS_COMPILE)g++
STRIP = $(CROSS_COMPILE)strip
CLEANUP = rm -f $(ALL_TARGETS) *.o *~
GPECOMP = gpecomp $(PROG_NAME).gpi $(PROG_NAME).gpe

CFLAGS=$(SDL_BASE) -O2 -Wall -Werror
CXXFLAGS=$(SDL_BASE) -O2 -Wall -Werror
LIBS= -LC:\gp2xallegro-0.3\lib

TARGET=$(PROG_NAME).gpe
SDLTEST_OBJS = $(OBJS)

all : $(TARGET)

$(TARGET)(SDLTEST_OBJS)
$(CXX)$(LDFLAGS)-o$(TARGET)$(SDLTEST_OBJS)$(LIBS)
$(STRIP) $(TARGET)
$(GPECOMP)
$(CLEANUP)


I thhink this could be what you want..?
In fact looking again this morning - there are a few problems with your makefile - eg ALL_TARGETS never gets defined and the heavy use of 'SDL' in it - doesn't matter but I wonder where you got this makefile?

 

[namco]

Had a go at it but it didn't want to know.

So in the end I switched to my "backup plan". I'm now using Slackware 11 (on qemu).

I've installed the devkitPro toolchain and now trying to configure allegro to build me the gp2x libraries.

I keep getting the error: "Sorry, mapped files are required for Linux console to work" in ./src/linux/fbcon.c:31:2

This is using the patched version of allegro 4.2.0 and when I run the configure when it says:

Oh and:
checking for arm-linux-gcc or even /usr/local/devkitPro/devkitGP2X/bin/arm-linux-gcc it says no. Is that going to be a problem?

Thanks for your help and patience.

 

[namco]

Update:

gotten arm-linux-gcc to be recognised but when it comes to modexgfx.s I get a load of errors about a bad instruction (they total about 1k of errors).

How many of you guys got the configure and make for the allegro working for the gp2x???

I'm doing this through Slackware and I was hoping that this would be much easier than windows.

 

[Orkie]

arm-linux-gcc? Sounds like an ancient toolchain or GPH's last one to me. Both are bad .

 

[namco]

ahhh, suppose I should give up with the devkitGP2X toolchain and use open2x instead??

 

[namco]

I'm now using the latest open2x compiler gcc-3.4.4 (glibc-2.3.6) and I get an unusual error when compiling allegro:

misc/asmdef.sh: line 50: unexpected EOF while looking for matching '
misc/asmdef.sh: line 54: syntax error: unexpected end of file

Has anyone come across this at all?
