Would this work on iOS 4.x?

It works on all firmwares, but currently iphone-gcc doesn't with headers that include block declarations (up to SDK 3.2 works)

I needed to replace every "ln -s" with "ln -fs" to overwrite already existing (but not up-to-date) symlinks, and add "--force-yes" to each apt-get call ('WARNING: The following packages cannot be authenticated!') to allow complete script execution.
Other than that, worked as expected, thanks! :)

Thank you, working well.
I'm using the 3.2 SDK and a modified gcc specs file (for -I, -L and -F parameters).
I could not compile fping, as some netinet headers are missing from the iPhoneOS SDK. I used this bash script:

for path in /Developer/Platforms/iPhone*/Developer/SDKs/*; do
    for file in /usr/include/netinet/ip.h \
                /usr/include/netinet/in_systm.h \
                /usr/include/netinet/ip_icmp.h \
                /usr/include/netinet/ip_var.h; do
        if [ ! -f "${path}${file}" ]; then
            sudo ln "${file}" "${path}${file}"
        fi;
    done;
done

from this web site: http://blog.slaunchaman.com/2010/02/13/using-apples-simpleping-on-iphone-os/ and could compile.
Thanks

Great job on this!

I did have to do two things to get this working:

  1. After doing a git clone, I had to add execute permissions to install-sdk
    chmod +x install-sdk
  2. In the install-sdk file, on line 44, change this:
    curl http://apt.saurik.com/cydia/debs/libgcc_4.2-20080410-1-6_iphoneos-arm.deb -o libgcc.deb
    to this:
    curl -L http://apt.saurik.com/cydia/debs/libgcc_4.2-20080410-1-6_iphoneos-arm.deb -o libgcc.deb
    The reason is apt.saurik.com redirects (HTTP 302) to cache.saurik.com. Without the -L option, curl will not follow to the new location and instead outputs an HTML file in libgcc.deb, which will not work.

Otherwise seems to be working. Thanks!

One more note... to get programs to compile, I had to tell gcc where the headers and libraries were located by setting a few environment variables.

Before compiling, you may want to run this in bash shell:

export C_INCLUDE_PATH=/var/sdk/usr/include

export CPLUS_INCLUDE_PATH=/var/sdk/usr/include

export LIBRARY_PATH=/var/sdk/usr/lib

ryanchapman: Thanks. I've added those changes. The proper way is to compile+link is to set the sysroot to /var/sdk. Theos, for example, does this already on iOS.

Where can I get libobjc.A.dylib? I dont want to download the entire xcode just for that file. Can you point me some other location?

After I installed iphone-gcc using the following command:
apt-get install iphone-gcc

Always prompt the following error:

iPhone:~/tmp root# apt-get install iphone-gcc
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package iphone-gcc is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'iphone-gcc' has no installation candidate

Do you know how to solve this error?
