Makefile:345: *** missing separator (did you mean TAB instead of 8 spaces?)

[Tartaruchi]

Anyone know what this means?

root@kali:~/Desktop/xSDM-master# make
Making all in src
make[1]: Entering directory '/root/Desktop/xSDM-master/src'
Makefile:345: *** missing separator (did you mean TAB instead of 8 spaces?). Stop.
make[1]: Leaving directory '/root/Desktop/xSDM-master/src'
Makefile:342: recipe for target 'all-recursive' failed
make: *** [all-recursive] Error 1

The same error happens with "make install" and even when I use " sudo make or sudo make install"

THANKS!

Could you provide your makefile content near that line?
