Just a silly question: Does Winarm support uClibc-0.9.19? I need the arm-uclibc-gcc compiler. Thanks, Daniel.

(Again:) WinARM is just a collection. The libc in this collection is the
newlib. It may be possible to compile the uClibc with the arm-elf-gcc
that comes with WinARM (or Yagarto or...) and use it as libc instead of
the newlib. But a better choice would be to build your toolchain "from
scratch". IRC there is rather detailled information on how to build a
toolchain with uClibc on their web-site. Since I have never tested
uClibc myself I can not give further information at the moment, maybe
someone else can jump in here.
Keep in mind that the uClibc is licensed under the LGPL which may be a
restriction.
Just curious: which functions do you miss in the newlib?

I really don't know. All my application is linked with uClibc-0.9.19, one of the few libs working with my target. I'm working on a project under uClinux and I thought that building the application from Windows could be nice for those unfamiliar with Linux (thinking in a GPL project). For Windows I wanted to compile just my application, not the kernel image, so I don't need to adapt the whole toolchain. arm-uclibc-gcc is the only executable to build for Windows but I don't know where to start. I'm currently downloading source files. Thanks.

The gnu toolchain from Keil uses uclibc instead of newlib, so have a look there as a start. I have used uclibc in the past as the footprint is slightly smaller than newlib (when using printf etc). Newlib can be tweaked to have a similar foorprint however. Be careful of the license with uclibc as it is LGPL not GPL as newlib. Regards Spen
