You can get the needed packages from. The following packages are needed from the download page: scratchbox-core, scratchbox-libs and scratchbox-toolchain-arm-glibc. All of those packages are provided as binary tar.gz, deb and rpm form. In this article we use .tar.gz files. The Scratchbox installation we are going to use takes about 522 mb of hard disk space and it will install under '/scratchbox/'. You will also need some extra space to work in. If you don't have enough space on your root partition then you can create a symbolic link to some other partition before continuing, e.g.: > mkdir /work/scratchbox > ln -s /work/scratchbox /scratchbox Scratchbox needs to be installed as root: > cd /tmp/ > wget http://www.scratchbox.org/download/files/sbox-releases/ 1.0/tarball/scratchbox-core-1.0.1-i386.tar.gz > wget http://www.scratchbox.org/download/files/sbox-releases/ 1.0/tarball/scratchbox-libs-1.0.1-i386.tar.gz > wget http://www.scratchbox.org/download/files/sbox-releases/ 1.0/tarball/scratchbox-toolchain-arm-gcc3.3-glibc2.3-1.0.1-i386.tar.gz > tar -xzf scratchbox-core-1.0.1-i386.tar.gz -C / > tar -xzf scratchbox-libs-1.0.1-i386.tar.gz -C / > tar -xzf scratchbox-toolchain-arm-gcc3.3-glibc2.3-1.0.1-i386.tar.gz -C / > /scratchbox/run_me_first.sh 'run_me_first.sh' asks you some questions, just use defaults. After this we need to add user for Scratchbox. User must be some user that you have in your system. Do NOT add root user! e.g.: > /scratchbox/sbin/sbox_adduser vmankine Scratcbox installation document [3] chapter number two helps you in installing the packages if you want to use for example .deb packages. 2.2. Down to business Let us first use the old fashioned way of cross-compiling and use the Scratchbox tools from the host system like any other tools. First we need a small piece of software to compile. "Hello World" will do fine: #include <stdio.h> int main(void) { printf("Hello World!\n"); return 0; } First let us compile the "Hello World" natively for X86 to see it works and to see some information about the binary produced. We assume you wrote the "Hello World" to a file named 'hello.c'. Now in the same directory where you have the 'hello.c' execute a command: > gcc -Wall -o hello hello.c It should not output anything and then you should have a 'hello' binary that you can run to get output of "Hello World!". > ./hello Hello World! Now for running a 'file' command to see some information about the 'hello' binary: > file hello hello: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.0, dynamically linked (uses shared libs), not stripped Any of this does not yet have anything to do with Scratchbox or cross-compiling for that matter. For cross-compiling we need to use the cross-compiler provided in the Scratchbox packages. Run command: > /scratchbox/compilers/arm-gcc-3.3.4-glibc-2.3.2/bin/arm-linux-gcc -Wall -o arm-hello hello.c Running that command should not give you any output but now you should have an 'arm-hello' binary. You cannot run that as it is for ARM architecture and you are on a X86 machine. Anyhow we can run the 'file' command to see that it really is an ARM binary: > file arm-hello arm-hello: ELF 32-bit LSB executable, ARM, version 1 (ARM), for GNU/Linux 2.0.0, dynamically linked (uses shared libs), not stripped Now we have cross-compiled our first application! If you have your IPAQ or equivalent ARM device running Linux you can of course try the application on that one. Just transfer the 'arm-hello' to IPAQ with e.g. scp and run it there normally..."
