afl-gcc-fast make Fail missing separator error

[nut799]

I post a message in here:
https://stackoverflow.com/questions/77651966/afl-gcc-fast-make-fail-missing-separator-error

when I use AFL++ to compile my project.

CC=*****/afl-gcc-fast CXX=****/afl-g++-fast make myproject

I get the error:

some.d:1 *** missing separator. Stop

And I open the some.d file:

[0;36mafl-gcc-pass [1;97m++4.08a[0m by oliva@adacore.com
[1;94m[*] [0mInline instrumentation at ratio of 100% in non-hardened mode.[0m
XXXX.o XXXX.d : XXXX.cpp
...
there is a "include some.d" in makefile. but I think the some.d is create by afl-g++-fast ?

So why this happens ,and How can I fix it?thanks

My demo project works well(build by alf++ ,run well), but when I build real project, I got this error.
