 Posted: Sat Jul 09, 2005 5:44 pm Post subject: On C++ with PSPSDK... again... |
 |
|
Hi all,
I've downloaded, installed (several times) the PSP SDK, Cygwin and all related tools. So far I've been able to compile C programs only, I've read several threads about C++ compilation with current version of PSPSDK, but so far I really had no luck in getting bpast the compilation fase.
I just tried to create a simple main.cpp file with a basic class declaration (containing just an integer member), in the main function I only declare an object of the class using the 'new' operator, assign a value to the class member and dispose the object using 'delete'.
file TEST.CPP
| Code: |
class TestClass {
public:
int m_K;
};
int xmain(void)
{
TestClass* TestObj = new TestClass;
TestObj->m_K = 1234;
delete TestObj;
return 0;
}
|
whenever I try to compile the above code, I only get errors.
Can please somebody write a basic Makefile with the all necessary options to compile it? I've been working with GCC on other embedded systems for years but this one seems to be a bit different from the others toolchain I've used and I can't find any doc. I was hoping that by looking at the SCUMM-VM PSP makefile I was able to solve the problem, but either I can't find the ported project (I know it is still under porting fase) nor there is an indication on what they had to change.
Thanx in advance.
Cheers,
Lev |

I've been able to compile your example with a simple makefile as this
PSPSDK = $(shell psp-config --pspsdk-path)
PSPLIBSDIR = $(PSPSDK)/..
TARGET = test
OBJS = main.o
LIBS =
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
include $(PSPSDK)/lib/build.mak |

Sorry for the incomplete question, this is the TEST.CPP file I've used:

This is the makefile:
| Code: |
TARGET = test
OBJS = test.o
INCDIR =
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
LIBDIR =
LDFLAGS =
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Test v1.0
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak
|
also I've modified the build.mak from:
| Code: |
PSPSDK_LIBC_LIB = -lpsplibc
|
to
| Code: |
PSPSDK_LIBC_LIB = -lpsplibc -lpspglue
|
when I tried to execute the makefile, this is what I get:
| Quote: |
psp-gcc -I. -I/usr/local/pspdev/psp/sdk/include -O2 -G0 -Wall -L. -L/usr/local/pspdev/psp/sdk/lib test.o -lpspdebug -lpsplibc -lpspglue -lpspkernel -o test.elf
/usr/local/pspdev/lib/gcc/psp/4.0.0/../../../../psp/lib/crt0.o: In function `__entrytable':
crt0.S:(.rodata.sceResident+0xc): undefined reference to `module_info'
test.o: In function `main':

test.cpp:(.text+0x20c): undefined reference to `operator delete(void*)'
collect2: ld returned 1 exit status
make: *** [test.elf] Error 1
|
I've read already the threads about problems in using the new and delete operators, tried several combinations of LIBS but so far no luck
Cheers,
Lev |

Seems to compile fine with an SDK fresh from SVN. Although you have to replace the dump_threadstatus() function with a more up-to-date one, some names have changed in the thread API.
So I guess the solution to your problem is: upgrade. :-)
