Recommend compile method and environment for su? - Android Q&A, Help & Troubleshooting

Edit 2:
I think I finally fixed this. The author needs to clean up this mess though. There is no reason to have to play a guessing game to compile something. Here are the fixes:
error: android_filesystem_config.h: No such file or directory
fix:
copy ~SOURCE_DIRECTORY/system/core/include/cutils
copy ~SOURCE_DIRECTORY/system/core/include/private
error: redefinition of 'struct iovec'
fix: remove body of source version of uio.h (there is an ndk and source version)
struct iovec {
const void* iov_base;
size_t iov_len;
};
extern int readv( int fd, struct iovec* vecs, int count );
extern int writev( int fd, const struct iovec* vecs, int count );
error: undefined reference to '__android_log_print'
fix: after LOCAL_STATIC_LIBRARIES add...
LOCAL_LDLIBS := -llog
Edit:
I have worked around this problem by using another version of the su/superuser source that I had downloaded previously.
A few changes were necessary to get superuser to compile:
add build.xml, add project.properties, add local.properties
r.java (remove line):
package koushikdutta.superuser;
strings.xml (change line):
remove " ' " from "phone's"
To compile su:
./agcc su.c -o su -I~/WORKING_DIRECTORY/external/sqlite/dist/ -I~/WORKING_DIRECTORY/bionic/libc/include/ -lsqlite
You can find the original source and my source link with all changes premade attached to this post or at this thread:
http://forum.xda-developers.com/showthread.php?t=1392593
I have tried to compile ChainDD's tar.gz from Github both with the NDK and with agcc. I am running 64 bit Debian Squeeze with the latest Android sources compiled and the NDK and SDK installed.
This line or variants:
agcc ~/bin/external/sqlite/dist/ -lsqlite su.c -o su -ldiskconfig -lcutils
gives:
undefined reference to 'send_intent'
ndk-build was not so good either. I had to do a lot of stuff to Android.mk to get it to continue further but still was not able to fully compile with it.
I have been able to compile another version of su I have found with agcc but it is only 10.5 Kb so I am not sure if it will work. I was also able to compile Zergrush with agcc.
I will reference these threads which show people having the same trouble as I am.

Anyone out there that can help? I have not done much cross compiling before now. Thanks.

Is there anyone out there who can help with this?

Maybe the OpenMoko Toolchain is needed to compile?
There must be someone somewhere out there (ChainsDD?) who has compiled this.

So I decided to make changes to get it to compile further.
su.h old:
struct su_initiator {
pid_t pid;
unsigned uid;
char bin[PATH_MAX];
char args[4096];
};
su.h new:
struct su_initiator{
unsigned pid_t;
unsigned pid;
unsigned uid;
char bin[PATH_MAX];
char args[4096];
};
That gets past the first error.
Then I get:
error: 'PATH_MAX' undeclared here (not in a function)
su.h old:
struct su_initiator{
unsigned pid_t;
unsigned pid;
unsigned uid;
char bin[PATH_MAX];
char args[4096];
};
su.h new:
struct su_initiator{
unsigned pid_t;
unsigned pid;
unsigned uid;
char bin[4096];
char args[4096];
};
Now I get a linker error:

I have tried editing the includes in activity.cpp but still with the same errors. Where to go from here?
