Host cygwin target ARM

Host cygwin Target ARM
In order to compile C programs to ARM executable files through a Windows PC, follow the steps here described. Alternatively, you may consider building your own toolchain.
Install Cygwin from http://www.cygwin.com; download for this http://www.cygwin.com/setup.exe, then select the standard options and verify that the development environment is included (devel, libs).
Start the bash and verify that a C source program can be correctly compiled to a Windows executable (.EXE).
Go to http://www.tomtom.com/page.php?Page=gpl
Download http://www.tomtom.com/gpl/rel200505b/toolchain/toolchain_cygwin_gcc-3.3.4_glibc-2.3.2_20050428a.tar.gz unpack the file to /usr/local/cross
If you get error messages like these tar tells you that some files are missing. Seems like the guys from Tomtom did not pack everything... ...but then the chain still seems to work. Go on. ;-)

Notice that you can also unpack a ttnsystem as described here http://wiki.opentom.org/index.php/Ttimgextract and then copy all NEW files in ttsystem\5.202\lib to /usr/local/cross/gcc-3.3.4_glibc-2.3.2/arm-linux/sys-root/lib without replacing already existing ones.
Perform then the following links:
$ cd /usr/local/cross/gcc-3.3.4_glibc-2.3.2/arm-linux/sys-root/usr/include/asm $ ln -s arch-s3c2410 arch $ cd /usr/local/cross/gcc-3.3.4_glibc-2.3.2/arm-linux/sys-root/usr/include/asm $ ln -s proc-armv proc
This is because the TTGO processor is a SAMSUNG ELECTRONICS S3C2410 (Arm920T), 32-bit architecture (so armv, while armo is for the old 26-bit ones).

export the PATH:
export PATH=/usr/local/cross/gcc-3.3.4_glibc-2.3.2/arm-linux/bin:$PATH:/usr/local/cross/gcc-3.3.4_glibc-2.3.2/bin
The cross compiler is now ready.
