+
Boot Log - Full boot messages produced by launching this system +image under qemu (using the "run-emulator.sh" script included in each system +image tarball), then typing "cat /proc/cpuinfo" inside the emulated system, +then "exit".
+

+ +

+
Cross Compiler - A compiler which runs on a standard PC host (x86 +or x86-64 Linux system) and produces output binaries for the specified $TARGET +architecture (Linux binaries linked against uClibc). To use, extract the +tarball and add its "bin" subdirectory to your $PATH, and then compile +with $TARGET-cc as your compiler name, such as:
+ +
+
```
+mips-cc root-filesystem-mips/usr/src/thread-hello2.c -lpthread -static -o hello
+
```
+
+ +
The "bin" subdirectory contains a bunch of tools prefixed with the $TARGET +name followed by a dash, such as "powerpc-strip". The "lib" subdirectory +contains shared libraries built for the target, including uClibc as the +standard C library to link binaries against and uClibc++ as the standard +C++ library. The "include" subdirectory contains the header files +#included by programs.
+

+ +

+
Native Compiler - A compiler which runs on the $TARGET and +produces output binaries which also run on the $TARGET.
+ +
You should be able to extract this inside an existing target system, add +its "bin" directory to the $PATH, and use it as you would the cross compiler. +(Except its binaries have no $TARGET- prefixes.) Note that when it creats +dynamically linked binaries they expect to find the dynamic linker at a specific +absolute path (under /bin).
+

+ +

+
Root Filesystem - A root filesystem for the target, suitable for +chroot-ing into, containing the smallest/simplest Linux development environment +capable of rebuilding itself from source code.
+ +
This system is based on busybox and uClibc, includes a native compiler +toolchain (binutils, gcc, linux headers), additional development utilities +(make, bash, distcc), and miscelaneous files and directories (such as some /etc +files and an sbin/init.sh boot script).
+

+ +

+
System Image - A bootable linux kernel and filesystem image +configured for use with the emulator QEMU.
+ +
The filesystem image contains the same set of files as the root filesystem +tarball, this time packaged into a squashfs. It also has Linux kernel +configured for qemu, and shell scripts to launch qemu to run this kernel +with this filesystem image.
+ +
Basically you download this tarball, extract it, cd into the directory, +and "./run-emulator.sh". This gives you a shell prompt inside the emulator, +ala the above screen shots. Type "exit" when done.
+

+ +

+
Static Busybox Binary - Busybox implements +hundreds of standard command line utilities in a single binary weighing in +somewhere around one megabyte.
+ +
Busybox is a "swiss army knife" binary, which behaves differently based on +the name of its executable. This means that populating a directory of +symlinks to the busybox binary can provide access to all these commands +without requiring multiple copies of the binary.
+ +
This binary is statically linked against uClibc, so can be run +independently on a target system, in a chroot environment, or via QEMU +application emulation.
+

+ +

+
Static Dropbear Binary - Dropbear is +a combination ssh server and client +in a single executable (another "swiss army knife" binary) that weighs in at +around 100k. It also includes scp and an encryption key generator.
+ +
This binary is statically linked against uClibc for maximum portability.
+

+ +

+
Static Strace Binary - Strace is a +debugging tool that runs a child process, sniffing all the child's +system calls and printing a description of them to stderr, ala:
+ +
+
```
+execve("/bin/false", ["false"], [/* 34 vars */]) = 0
+brk(0)                                  = 0x14ca000
+mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fb
+e69a44000
+access("/etc/ld.so.nohwcap", F_OK)      = -1 ENOENT (No such file or directory)
+...
+
```
+
+ +
And so on. If a binary is failing or hanging, strace can give you an +idea of what it's doing, at least when it interacts with the rest of the +system.
+ +
This binary is statically linked against uClibc for maximum portability.
