lua on PSP (not lua player !)

[zoret]

hi,

i have to read my own lua script without using the excellent (but too complete in my case) luaplayer
any ideas ?
i had a look inside the lua player samples but the lua lib files (header and lib) are not present...

thanks in advance !

[PeterM]

Check out http://www.lua.org and download the source, and the docs.

Hope this helps,
Pete

[zoret]

yes i can indeed compile all by myself but just wanted to know if anybody had already compiled and created the lua libraries for the psp toolchain ?
it's just to not waste my time if it available somewhere ..

thanks !

[PeterM]

Sorry, I didn't realise that.

I think it's available on the PS2Dev Subversion server:
http://svn.ps2dev.org/listing.php?repna ... rev=0&sc=0

[zoret]

great !! thanks a lot !

[zoret]

it looks to contain what i'm looking for but i don't see any download button !??
i must be missing something ! :)

[PeterM]

Open up a cygwin window and type:
svn co svn://svn.ps2dev.org/psp/trunk/lua

[zoret]

great it seems to work except i don't have the permission !? :-(
i've the following error :

svn: Can't connect to host 'syn.ps2dev.org': Connection refused


any ideas ?

[PeterM]

You've typed "syn.ps2dev.org" there - is that a typo?

The line I gave should work - it worked for me, I tested it before posting.

Pete

[zoret]

yep you right, just a little error in what i've typed
now it's ok
thanks a lot !!

[PeterM]

You're welcome.

Pete

[zoret]

ok now i can compile and test the lua sample
i've modified it and everything works perfectly
so i've tried to put some lua stuff in my own code

but when i try to link with lua libs : -llualib -llua (like in the lua sample !)
i've the following errors :

i've searched for the maths functions asked but nothing (except this from lua package) contains these !!!

i really don't understand how the lua sample can link !
there's somthing strange here !!

any ideas welcome !

here is the makefile i use :

Code: Select all

TARGET = nXviewer
OBJS = nXviewer.o _libs/callbacks.o _libs/vram.o

INCDIR =
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

LIBDIR =
LDFLAGS =
LIBS= -lpspgum -lpspgu -lm -lpspusb -lpspusbstor -llualib -llua

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = nXviewer

PSPSDK=c:/cygwin/usr/local/pspdev/psp/sdk#$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

ifneq ($VS_PATH),)
CC       = C:/cygwin/usr/local/pspdev/bin/vs-psp-gcc
CXX      = C:/cygwin/usr/local/pspdev/bin/vs-psp-g++
endif


XTARGET = $(shell echo $(TARGET)000000 | cut -b1-6)
KXDIR = $(TARGET)
KXDUMMY = $(TARGET)%
 
kxploit: $(TARGET).elf $(PSP_EBOOT_SFO)
	mkdir -p "$(KXDIR)"
	$(STRIP) $(TARGET).elf -o $(KXDIR)/$(PSP_EBOOT)
	mkdir -p "$(KXDUMMY)"
	$(PACK_PBP) "$(KXDUMMY)/$(PSP_EBOOT)" $(PSP_EBOOT_SFO) $(PSP_EBOOT_ICON)  \
	$(PSP_EBOOT_ICON1) $(PSP_EBOOT_UNKPNG) $(PSP_EBOOT_PIC1)  \
	$(PSP_EBOOT_SND0) NULL $(PSP_EBOOT_PSAR) 
	cp -r $(KXDIR) $(PSP_MOUNT)/PSP/GAME/
	cp -r $(KXDUMMY) $(PSP_MOUNT)/PSP/GAME/ 
                

if someone could tell be wich library contains theses maths functions i could check my sdk and update if needed
but that doesn"t explain how the lua sample can link !! ???

[zoret]

ok i've just found it !
the lua libs need the lm lib so i have to put this lib at the end of the libs list

i've simply modified my makefile :

LIBS= -lpspgum -lpspgu -lpspusb -lpspusbstor -llualib -llua -lm

the linker is rather dumb...

nevermind, now it works !!

[PeterM]

Glad it works now - yes, the fact that order is important in linking really is a pain sometimes.

I wonder if this feature actually has any practical use...
