 |
|
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 ! |

Check out http://www.lua.org and download the source, and the docs.
Hope this helps,
Pete |

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 ! |

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.

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: |
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 !! ??? |

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 !! |

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... |
