This is fer64 (64 bit Fermat v. 7.0) for Linux as an archive. This can be linked with your C application.


Each update is more fully described here or here


7.0 was compiled and uploaded on September 5, 2023.


6.31 was compiled and uploaded on October 19, 2020.


6.3 was compiled and uploaded on October 19, 2019.

Those who have their own C programs can now use the superb polynomial and quolynomial arithmetic of Fermat by just compiling with the archive found here.


In the archive, look at the makefile called makear. This is the one I used. It may not be optimal.


Warning: The optimizer in the most recent versions of gcc has been changed. Choosing level 4 or 3 can result in a buggy app.

arch.c the sample main program. Replace it with your own.


rstuff is a sample file of Fermat commands that can be read by your program (here arch.c).


arch.c and rstuff were revised in July 2017. Apparently the previous versions work fine on some Linux systems but not others. There is also new documentation and more illustrations of commands. ferlib.a was updated on January 5, 2018 and several times since.


BACKWARD is the usual Fermat auxiliary folder. It has to be in the same folder as arch.c.
