Please read the common errors and solutions page, it has your answer.

[Twenty 2]

ya im a newb to this so i dont exactly know what to look for

[Agoln]

Please, use the search function. It is your friend. Just because you are new to developing applications on the PSP doesn't mean that you have the right to not do any work yourself.

Here, I did your work for you and linked the thread. Read THIS thread.

[Twenty 2]

Sorry i knew where the thread was i just didnt know which would answer my question...

[Agoln]

If you look at your code, you will see that you have:

y:\drive\c\Program Files\PSPDev\psp\lib\crt0.o In function `__entrytable':
[Linker error] undefined reference to `module_info'
y:\drive\c\Program Files\PSPDev\psp\lib\crt0.o ld returned 1 exit status
C:\Dev-Cpp\Makefile.win [Build Error] [Project2.exe] Error 1

Does that not look similar to:

Q: In function `__entrytable':
crt0.S:(.rodata.sceResident+0xc): undefined reference to `module_info'
A:Make sure that you have PSP_MODULE_INFO("SOMETHING", 0, 1, 1); somewhere in your program.

wow.. im not a morning person lol but thnx man.

[Mura]

i have no problem in setup the environment in dev cpp. but i have encountered error when compiling it. the output of error are.

Code: Select all

 C:\Dev-Cpp\project\Makefile [Build Error]  No rule to make target `main.o', needed by `project.elf'.  Stop. 

details :

my project.dev file is in Dev-Cpp folder, my project file, main.c and Makefile are in a directory named testpower

Code: Select all

-Dev-Cpp
 |_ project1.dev
 |_ testpower
    |_ main.c
    |_ Makefile
 |_devcpp.exe

thanks.[/code]

I got the same error ,please help

BTW,in console mode ,there was no error

[Agoln]

I got the same error ,please help

BTW,in console mode ,there was no error

Are you using a custom make file? or an auto-generated one?

[Mura]

I know the problem now.

We should put the project file (*.dev) and the "makefile" in a same directory.

Thank you for your help :)

lol

[Squall333]

I keep getting

makefile:17: C:/pspdev/psp/sdk: Permission denied
makefile:17: /lib/build.mak: No such file or directory
make: *** No rule to make target `/lib/build.mak'. Stop.

So i just need this to begin programming with c++ to PSP??
I have read some tutos that talk in install cygwin, psptoochain...

I am a little confused...

The win32 package is outdated, and I have udpated the page to point to the programming FAQ wiki page.

After you read the wiki, then follow the rest of the directions in order to set it up.

[XRS]

Oh, ok!
Thanks...i will read it!

Hi all,

I've just downloaded the libpng and the zlib from the svn repository.
They compiled fine with Dev-C++, creating the libpng.a and zlib.a librairies. I've installed them into the $(PSPSDK)/lib dir.

Now I'd like to compile a piece of code taken from Shine's graphics.c file (from the LuaPlayer source), just to see if I can display a PNG picture on my PSP.

Compilation is okay, but I keep having the following linker errors :

Code: Select all

make.exe -f "Makefile" all
psp-gcc -I. -I/cygdrive/c/pdev/psp/psp/sdk/include -O2 -G0 -Wall  -L. -L/cygdrive/c/pdev/psp/psp/sdk/lib   main.o -lpng -lz -lpspdebug -lpspdisplay -lpspge -lpspctrl -lpspsdk -lc -lpspglue -lpspuser -lpspkernel -o hello.elf

Is libpng recompiled each time ?
I tryed to search these forums, badly I guess, because I can't find an answer :/

By the way, here is my Makefile (I use a custom one from the SDK, not the one generated by Dev-C++) :

Code: Select all

TARGET = hello
OBJS = main.o

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

LIBDIR =
LDFLAGS =
# My extra libs
LIBS = -lpng -lz

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Hello

PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

Any help would be greatly appreciated, thanks !

[holger]

try adding -lm to your LFLAGS/LDFLAGS/LIBS. Maybe you also want to update your toolchain (and move the old toolchain tree away to keep it clean) -- as far I know libpspglue.a is not used anymore.

[maestun]

Thanks for your answer, I'll try this as soon as I can :)
By the way, what does the "-lm" flag mean ?

The other thing I was wondering : has the libpng to be recompiled from scratch each time I want to compile some code using it ?
It's this kind of error messages :

Code: Select all

pngrtran.c:(.text+0x1264): undefined reference to `pow' 

...that makes me think of this (since pngrtran.c is part of the libpng distribution)

EDIT :
--------
Okay, I added -lm (I guess it's the math funcs lib ?), also -lpspgu, everything compiles fine now.
Thank you very much for your help :)

***
Nb to admins : should I better create a new topic for these questions instead of posting here ?

[Agoln]

It's fine to post that here, cause others may have questions about it....

and yes, -lm links in the math library.

[Mr.Modem]

I get this error message when I run the toolchain script:

Code: Select all

***proc magic mismatch detected - 0xD94C588A/0xD079E02

This problem is probably due to using incompatible versions of the cygwin DLL
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version.  The most recent version *should* reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution.  Rebooting is also suggested if you
are unable to find another cygwin DLL.
no
configure: error: installation or configuration problem: C compiler can
e executables.
ERROR CONFIGURING BINUTILS

I've reinstalled cygwin and the DLL is the latest version. What should I do?

[urchin]

Sounds like you have two different versions of cygwin clashing somehow.

I once hit the same problem opening a bash window and running an older cygwin version of make (killing the build process that had been running in another window for 4 hours grumble grumble)

[Mr.Modem]

I don't think I have two version of Cygwin running

[urchin]

Did you follow the error instructions and see how many copies of "cygwin1.dll" you have on your machine?

[Mr.Modem]

I've reinstalled Cygwin (again) and I didn't get the error. I guess there were something wrong with my previous installation.

[Kro]

The current one I am using inside of Dev-C++ is this:

Code: Select all

TARGET = bitmapViewer
OBJS = main.o pspBMP.o

INCDIR = 
CFLAGS = -O2 -G0 -Wall -I"C:\Program Files\PSPDev\include"
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

LIBDIR =
LDFLAGS =

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Bitmap Viewer v0.1
PSP_EBOOT_ICON = icon.png
PSPSDK= C:/Progra~1/PSPDev/psp/sdk
include $(PSPSDK)/lib/build.mak

Small sugestion:
Keep directory structure in this manner:

Code: Select all

[X]
 |
 +--[Projects]
     |
     +--[MyProject1]
     |
     +--[MyProject2]
     |
     +--[MyProject3]

Where X is whatever you wish (DevCpp directory, its subdir, directory aoutside DevCpp - whatever). You can place Makefile.def inside Projects directory:

Code: Select all

CXXFLAGS=$(CFLAGS) -fno-exceptions -fno-rtti 
EXTRA_TARGETS = EBOOT.PBP 
include $(PSPSDK)/lib/build.mak

And for each project create makefile (and set as a custom makefile for given project), e.g.

Code: Select all

TARGET=MyProject
OBJS=main.o
PSP_EBOOT_TITLE=MyProject v0.1
#uncoment following line if you want (and have) custom icon
#PSP_EBOOT_ICON=icon.png
LIBS= -lpspgu

include ../Makefile.def

These are the only project-specific values for 90% of your projects (of course values assigned to variables will vary).

Some vars you've defined (INCDIR, CFLAGS, CXXFLAGS, ASFLAGS, LIBDIR, LDFLAGS) are already defined inside build.mak (%PSPSDK%\lib directory). The only value required is PSPSDK environment variable. Instead of typing it in, click right mouse button on My Computer (for Windows Vista: Computer), Properties, Advanced (tab), Environment Variables (button), New (for user or system variables - whatever you feel better; I'm developing on separate account, so user variable is ok for me). Setting environment variable is preferred over setting %PSPDEV% inside makefile.

First change that matters, my CFLAGS now has a -I"C:\Program Files\PSPDev\include" bit to it.

As stated before - only env var is required when using build.mak.

I changed "Program Files" to "Progra~1"

Just in case - use dir /x under command line to get DOS file/dir name. It is possible, that "Program Files" is not "Progra~1".

[jsharrad]

Is there any way to make it so dev-cpp can make a v1.5 eboot like using "make kxploit" in cygwin?

[LordCthulu]

Followed the link in the first post, and there was only a folder, so I followed through a few folders and ended up here:

http://www.cs.purdue.edu/homes/ljbuesch/cs177/lab1/


Which...doesn't show how to setup Dev-C++ ^^;
(It's a quickie guide on Unix...lol)

[UsefulIdiot]

anyone got a mirror of this?

[rapso]

i nearly got it working now, but there is a linker error and i dunno what might be the problem.

...
-lpspnet_apctl -lpspnet_resolver -lpsputility -lpspuser -lpspkernel -o .elf

/usr/local/pspdev/lib/gcc/psp/4.0.2/../../../../psp/lib/crt0.o: In function `_main':
/tmp/pspdev/pspsdk/src/startup/crt0.c:86: undefined reference to `main'
collect2: ld returned 1 exit status
...

maybe it's just a n00b-bug :(

btw. i try to compile the source off the controller sample, so there is an int main(void)..

@Agoln: Somehow your links is dead.
So would someone please post a new
link to the tutorial?

Thx

ditto. Please link us, as I would love to be able to c for psp, but cygwin didn't work for me...
