http://www.psp-programming.com/tutorials/c/lesson04.htm
Been following some samples from here when I got time and tried to do a graphic program and when I do Make I get...
| Code: | psp-gcc -I. -I/home/username/source/psptoolchain/pspdev/psp/sdk/include -I. -I/usr/mispel-unknown-linux-uclibc/usr/include -O2 -G0 -Wall -D_PSP_FW_VERSION=150 -c -o graphics.o graphics.c
graphics.c: In function 'loadImage':
graphics.c:79: error: 'png_infopp_NULL' undeclared (first use in this function)
graphics.c:79: error: (Each undeclared identifier is reported only once
graphics.c:79: error: for each function it appears in.)
graphics.c:85: error: 'int_p_NULL' undeclared (first use in this function)
graphics.c:99: warning: implicit declaration of function 'png_set_gray_1_2_4_to_8'
graphics.c:118: error: 'png_bytep_NULL' undeclared (first use in this function)
make: *** [graphics.o] Error 1 |
My Makefile is...
| Code: |
TARGET = hell
OBJS = main.o graphics.o framebuffer.o
CFLAGS = -I/usr/include
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
LIBDIR =
LIBS = -lpspgu -lpng -lz -lm
LDFLAGS =
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Image Example
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak |
The lines in question are....
| Code: | 78: fclose(fp);
79: png_destroy_read_struct(&png_ptr, png_infopp_NULL, png_infopp_NULL);
80: return NULL; |
| Code: |
84 png_read_info(png_ptr, info_ptr);
85: png_get_IHDR(png_ptr, info_ptr, &width, &height, &bit_depth, &color_type, &interlace_type, int_p_NULL, int_p_NULL);
86 if (width > 512 || height > 512) { |
| Code: | 89: png_destroy_read_struct(&png_ptr, png_infopp_NULL, png_infopp_NULL);
90: return NULL;
91: } |
| Code: |
117: for (y = 0; y < height; y++) {
118: png_read_row(png_ptr, (u8*) line, png_bytep_NULL);
119: for (x = 0; x < width; x++) { |
I did a line before and after the one that is shown in the errors because sometimes I've noticed the error is a line off.
Sorry for how long the post is just thought I'd try to be as clear as possible |

| Yep, just recompiled it in case. I had to recompile it for the mips architecture for it to get passed a previous issue I had before. |

try the one on the PSPdev Subversion Respository.
Svn co svn://svn.ps2dev.org/psp/trunk/libpng
then cat into Readme.PSP for installation instructions |

| Well after a bit of reluctance I decided to follow the guide exactly... I was trying to use my host system library files(which didn't work) and then tried cross compiling for the psp(which caused a bunch of other problems for me). But following the guide got me going heh |
