macOS how to new a std c++ class in iphone programming

[krautrockblog]

i try to build a iphone game by porting from the existing c++ game source code. but the trouble is that i cannot new a std c++ class. note that i have installed the recent iphone toolchain and can compile doom source code etc correctly,the doom sample source is c, not c++. (i can build a helloworld as well,which is object c).
i have tried with apple-darwin-gcc or apple-darwin-g++.always failed.
anybody knew how to handle with this trouble?

Same question as mine. Anyone can help us?

Is this the unofficial SDK that's floating about?

This might be a stupid question, but are you sure it supports C++? The only samples I've seen are Obj-C.

What is the compiler error message?

hrrrr,I have fixed the problem.
Some suggestions are as following:
1\ change all *.m files ext to *.mm
2\put your c++ code in *.cpp files
3\change your makefile .

CC=arm-apple-darwin-gcc
CXX=arm-apple-darwin-g++
LD=$(CXX)

LDFLAGS=-lobjc -framework CoreFoundation -framework Foundation -framework UIKit -framework LayerKit
LDFLAGS+=-L/usr/local/lib  -lz -lstdc++

CFLAGS=-Wall -O2
CFLAGS   +=   -I/usr/local/include 

all:    hello

hello:  Hello.o HelloApplication.o hello1.o
	$(LD) $(LDFLAGS) -o $@ $^

%.o: %.mm
	$(CC) -c $(CFLAGS) $(CPPFLAGS) $< -o $@
	
%.o: %.cpp
	$(CC) -c $(CFLAGS) $(CPPFLAGS) $< -o $@

clean:
	rm -f *.o hello

4\in *.mm files ,you can new a class.


hmmmm,if you still have questions,please send email to me.[pchard AT 126 DOT com].

I have another questions:
How to user BSD socket in iPhone?
The following code is not work:

	NSString* hostName = [[NSString alloc] initWithString:@"www.google.com"];
	unsigned short port = 80;
	
  struct hostent* remoteHost;
    struct sockaddr_in remoteAddr;

    // Socket must be created, and not already connected
    if ( (socketfd = socket(AF_INET, SOCK_STREAM, 0)) < 0 )
        [NSException raise:SOCKET_EX_CANT_CREATE_SOCKET 
                        format:SOCKET_EX_CANT_CREATE_SOCKET_F, strerror(errno)];
                        
    if ( socketfd == SOCKET_INVALID_DESCRIPTOR )
        [NSException raise:SOCKET_EX_BAD_SOCKET_DESCRIPTOR 
                        format:SOCKET_EX_BAD_SOCKET_DESCRIPTOR];
    connected=NO;
    if ( connected )
        [NSException raise:SOCKET_EX_ALREADY_CONNECTED 
                        format:SOCKET_EX_ALREADY_CONNECTED];
    
    // Look up host     
    [COLOR="Red"]if ( (remoteHost = gethostbyname([hostName cString])) == NULL )   return NULL,WHY?
