Re: [Bug-gsl] gsl to arm

[Sergio Valcarcel]

Hi Shienquiang,

First of all, I assume you have some arm-none-eabi toolchain. If not, either
you can follow this link to build your own for 64bit machines:

http://gaps.ssr.upm.es/images/sergio/How_to_set_TinyOS-2-1-1_and_imote2_toolchain_in_Ubuntu_10-10_intel_64bits.pdf

Or you can get these installation packages we built:

http://gaps.ssr.upm.es/es/investigacion/wsn/138-compiling-for-an-arm-architecture-imote2-tinyos

Or you may get any other already built (like from CodeSorcery...).

Once you have your toolchain ready, then export the CC, the PREFIX of the
binaries, the CFLAGS for your architecture, the TARGET as arm-none-eabi and
the kind of HOST as machine you are using to compile. Configure, make and
install. I remember most of that is explained in the readme files.

Note the CFLAGS are architecture dependent, so you may want check for your
own (regarding the gcc options check this link:
http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/ARM-Options.html)

Just to advice that I have found many bugs when using the library. Some
depend on the float/double representation, some other on the way the
functions are coded. So I had to patch myself. Another handicap is the
memory footprint, which is quite big... And you might be interested in
compiling some functions only.

Cheers!
Sergio
