Hello,
i can't compile c++ code. i'm on iOS 4.1. c code works fine, but if i try to 
compile c++ code, the compiler says "..iostream.h error: std::...has not been 
declared."
Is there any possibility to compile c++ code?

Hey
I'm trying to compile a hello world app using g++ on my Ipod Touch 2.2.1. 
With Ubuntu 9.04, using SSH in terminal for communication. Simple the
source looks like this:
-----------file: helloi.cpp-----------
#include <iostream>
using namespace std;
int main(){
cout<<"Hello World";
return 0;
}
--------------------------------------
Running the following command in terminal: g++ helloi.cpp -o helloi
Gives the following output:
-----------------------------------------------------------
Basels-iPod:/ root# g++ helloi.cpp -o helloi     
helloi.cpp:1:20: error: iostream: No such file or directory
helloi.cpp: In function 'int main()':
helloi.cpp:4: error: 'cout' was not declared in this scope
Basels-iPod:/ root# 
-----------------------------------------------------------

I've installed all the headers and libraries. And iostream does exist in
"/usr/local/include/c++/4.0.0" But for some reason it can't find it.

g++ can find other headers and libraries like stdio.h

I ran also the "-v" parameter and it gives the following output:

-----------------------------------------------------------------
Basels-iPod:/ root# g++ -v helloi.cpp -o helloi

The compiler did obviously not find the following directories which include
iostream.

----------------------

The directorys are in fact in "/var/include". So I linked to these
directories. The linking was somehow successful. But the result from the
compiler isn't pretty :P. It just gave me more errors. Take a look at the
output:

The output is actually more than that, but I can't post the whole thing.

I've also tried all of this with gcc instead of g++ with the same result. 

I've tried fixing this for 6 hours now, and am going nuts!!!

I appreciate all the help I can get!!

Brief description of problem - the more info you provide the less ttl the 
problem has...


MOST IMPORTANT QUESTION: CAN YOU printf("Hello, World); ?


What steps will reproduce the problem?
1. Install iphone-gcc on iPhone 3G with 3.1.3.
2. Attempt to compile rtmpdump
3.

What is the expected output? What do you see instead?

While attempting to compile rtmpdump and telling it INC="-I/...." the location 
of OpenSSL or simply not even putting INC= which worked before, it claims my 
OpenSSL is too old, yet if I do "cp -r /usr/include/openssl /var/mobile" then 
do INC="-I/var/mobile/" oddly the exact same headers now work.


What firmware version of itouch/phone?



What Computer operating system?


Please provide any additional information below.

Steps to prepare environment (running on firmware 2.0 5A347, jailbroken,
with Cydia):

1. on iPhone: apt-get install iphone-gcc make ldid
2. on Mac (Leopard, Xcode 3.0, iPhone SDK final version): rsync over
/Developer/SDKs/MacOSX10.4u.sdk/ from mac to iPhone
3. on iPhone: svn co
http://iphone-dev.googlecode.com/svn/branches/include-1.2-sdk
4. cd include-1.2-sdk ; ./configure ; chmod +x install-headers.sh ;
./install-headers.sh

Try to compile something on the iPhone, e.g.
arm-apple-darwin9-gcc -c -I/usr/local/arm-apple-darwin/include  MyExample.m
-o MyExample.o

This should compile the code and produce something ready to be linked

Instead we get this error (and LOTS more after):

What steps will reproduce the problem?
1. Write a simple HelloWorld.c program. 
2. Compile via iphone gcc

What is the expected output? What do you see instead?
1. A working Hello World program.
2. An error: Error: <stdio.h> no such file or directory


What version of the product are you using? On what operating system?

4.2

Please provide any additional information below.

Installed via cydia

Hello,
I have ipod 1g 3.0 sw. I was able to compile hello world and some cocoa touch 
apps with user 
interface and advance features. I have copied header files to 
usr/local/include, also frameworks. C, 
objective c works great, but not c++. I assume the problem might be the 
compiler flags. Any ideas?
??

For the IDE I am using Backgrounder for a fast switch between termainal.app and 
iFile. Would be 
nice to have it all in one app. Also, Erica Sadun's "launch" command line 
utility is not working on 
3.0.

Brief description of problem - the more info you provide the less ttl the
problem has...
When I build an app with iphone-gcc running the application writes 'Killed'
to stderr.
It also does this with the new toolchain that I built on my macosx leopard
machine... something wrong with my iPhone?

I have copied the headers to /usr/include and am using iPhone 1.2/2.0
firmware modded using pwnage 2.0.1

What steps will reproduce the problem?
On iPhone...
1. > echo 'main() { printf("Hello, World!\n"); }' > main.c
2. > gcc -o main main.c
3. > ./main
4. Killed
5. > 


What firmware version of itouch/phone?
1.2/2.0 firmware modded using pwnage with cydia, then installed iphone-gcc
via apt-get from command line.

Please provide any additional information below.
Original iPhone 2G.  I was trying to get a simple smssend console
application to build using the toolchain on macosx leopard and experienced
the 'Killed' message.  Then I modified my make file and stuck the whole
application on the iphone and tried to build using iphone-gcc.  It appeared
to build cleaner than on the pc, but same Killed message.  Then I tried to
build the 'hello world' test app using iphone-gcc and same message.

Any help anyone could give would be great.
