large integer support in GNUPro for Altera Nios software dev

[Maxlim]

Hello,
I'm trying do implement some large integer operation
(Multiple-precision arithmetic) in Nios software application (modular
addition, multiplication and inverse). I'd found a few complicated
library files and it's work perfectly in Windows and Linux
environment. When I try to compile by using GNUPro compiler, a lot of
standard header files is missing.
Does anybody know solutions for this problem? Or any simpler
source code accompany with step by step instruction for beginner?

I would tackle it one .h file at time. Do a search and make sure you don't
already have the required header files, but your compiler search path is not
including their location. Then, if you don't have them, start copying them
over from the working systems. Or possibly do a search on sourceforge, etc.

You could also post the particular header filenames here with for better
help.

Thanks a lot, Ken. I tried to copy all header files needed by the
library into nios-gnupro/nios-elf/include folder when the compiler
asking for those files. After I'd done that, a lot of errors appeared.
It seem like the library files for multi-precision arithmetic is not
supported by GNUPro compiler. Is there any other multi-precision
arithmetic library files available for GNUPro compiler?

Hi Maxlim,

I am still not sure what you mean by "multi-precision" - you you mean
"floating point"?? The GNU toolset/GCC compiler/associated libraries
do support floating point math. Declaring a variable as "float",
"double", or "long long" (fixed point) should work. There is also a
library include, 'math.h' which provides more advanced math beyond the
basic arithmetic and logical operands (this is getting into the area
where the rednat/gnupro documentation should cover things). One piece
of advice I can give you is that all the paths required for default
libraries should be setup when you installed Nios -- so copying
library files around might cause more harm than good.
