我已经在把内核编译好了，没有问题，打开home/book/linux-2.6.35.7-gec-v3.0 有 Makfile文件，请问以下是怎么一回事！！
book@book-desktop:/work/drivers_and_test/first_drv$ make
make -C /home/book/linux-2.6.35.7-gec-v3.0 M=*pwd* modules
make[1]: Entering directory `/home/book/linux-2.6.35.7-gec-v3.0*

make[2]: *** No rule to make target `/home/book/linux-2.6.35.7-gec-v3.0/pwd/Makefile*. Stop.
