Hi
I downloaded gnats3999.1.tar.gz.
I was trying to compile it .But I get the following error message
> make[1]: Entering directory "/home/nsingh/gnats3.999.1/doc"
> makeinfo -I . -o gnats.info gnats.texi
> make[1]: *** [gnats.info] Bus Error
> make[1] Leaving directory "/home/nsingh/gnats-3.999.1/doc"
> make: ***[all-gnats] Error 2
>
I don't know how to solve this problem.Any help will be appreciated

Thanx
