Hi to all, i need help :)

i'm working on tool in gslib and i need to use libjpg but i have problem with make file:

EE_BIN = jpg.elf
EE_OBJS = jpg.o

EE_LIBS += -lgcc -lgs -ljpg -lc -lkernel -lc -lsyscall -ldebug -lsyscall -lkernel


EE_INCS += -I$ ./INC
EE_LDFLAGS += -L$ ./LIB

all&#58; $&#40;EE_BIN&#41;

clean&#58;
	del *.elf *.o *.a


include $&#40;PS2SDK&#41;/samples/Makefile.pref
include $&#40;PS2SDK&#41;/samples/Makefile.eeglobal

in subdir LIB i have put libgslib.a and libjpg.a
in subdir INC i have put all needed file include by two lib

when i compile:

Code: Select all

ee-g++ -D_EE -O2 -G0 -Wall  -IC&#58;\PS2Dev\COMPILER\LIB\PS2SDK/ee/include -IC&#58;\PS2D
ev\COMPILER\LIB\PS2SDK/common/include -I. -I./INC -c jpg.cpp -o jpg.o

Are you sure it isn't 'libjpeg.a' instead of 'libjpg.a'?

If so, you'd need a '-ljpeg'.

yes i'm sure

is libjpg Ported by linuzappz on cvs root, not libjpeg from ps2sdk-ports

if you want i post link with my test sourcecode

EDIT: you can download my test source code here

<emoonwork> you need -lstdc++ to get rid of __gxx stuff atleast
<sincro> i try emoonwork
<emoonwork> ooPo: maybe no extern "C" {...} in the header for the C functions?
<ooPo> hmm, that's quite possible
<sincro> <emoonwork> with -lstdc++ i solve __gxx stuff problem
<ooPo> yup, no extern in the header
<sincro> but other undefined reference have problem
<sincro> i have past source code link on forum
<ooPo> http://cvs.ps2dev.org/libjpg/libjpg/inc ... .h?rev=1.3
<emoonwork> ok, no extern "C"
<ooPo> just put some around where it is included in his code
<emoonwork> yeah
<sincro> ?
<sincro> extern c in source?
<sincro> ok i try

Code: Select all

#ifdef __cplusplus
extern "C" &#123;
#endif

#include <libjpg.h>

#ifdef __cplusplus
&#125;
#endif

<sincro> YEAH compiler work
<sincro> tnx tnx tnx
<sincro> :)
