Hello,

I recently tried to use SDL mixer in my SDL app, and I am getting an error. I installed the latest version from the SVN, built and installed it. I am using cygwin and the bash shell to install. When installing, I received the following error:

checking for C compiler default output file name... configure: error: C compiler
cannot create executables
See `config.log' for more details.

I ran this version of configure, just as it appears in reame.psp:

LDFLAGS="-L`psp-config --pspsdk-path`/lib -lc -lpspuser" ./configure --host psp --with-sdl-prefix=`psp-config --psp-prefix` --disable-music-mp3 --prefix=`psp-config --psp-prefix`

I went to an old SDL checkout I had, and found the older command to run configure was as follows:

LDFLAGS="-L`psp-config --pspsdk-path`/lib -lc -lpspuser -lpsputility" ./configure --host psp --with-sdl-prefix=`psp-config --psp-prefix` --disable-music-mp3 --prefix=`psp-config --psp-prefix`

The second command worked and installed SDL_mixer correctly. It only differs from the first in that it has the "-lpsputility" option.

When I try to use SDL mixer in a program, I get the following errors:

It appears that the installed libraries are somehow pointing to the directory where I compiled/installed SDL_Mixer from (psphome/devtools/20051208/SDL_mixer/). I have no idea how that could be possible. My makefile is as follows:

TARGET = sp
OBJS = sp.o hero_manager.o sprite_manager.o map_manager.o bg_manager.o power_manager.o
OBJS += zip_manager.o unzip.o ioapi.o image_manager.o dl_manager.o


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

LIBDIR =
LDFLAGS =

EXTRA_TARGETS = EBOOT.PBP kxploit
EXTRA_CLEAN = my-clean

PSP_EBOOT_TITLE = SP
PSP_DIR_NAME = SDLTEST

PSPSDK=$(shell psp-config --pspsdk-path)
PSPBIN = $(PSPSDK)/../bin
CFLAGS += `$(PSPBIN)/sdl-config --cflags` -DNOUNCRYPT
LIBS = `$(PSPBIN)/sdl-config --libs` -lm -lSDL_gfx -lSDL_image -lSDL_mixer -lpng -lz -lm -ljpeg -lpspwlan -lpspgu -lpsppower
include $(PSPSDK)/lib/build.mak

Does anyone have any idea why I am getting these weird compiler errors when trying to compile a program using SDL_Mixer? Could it have something to do with ./configure not running correctly using the newer version from the latest SDL_Mixer's readme.psp? Any help is appreciated!

You need to update Newlib as it's way old. Then move the -lSDL_mixer library before the SDL libraries since it depends on them (same for SDL_image).
