For help, I just learned linux and got stuck on makezImage of the kernel.

For help, I just learned linux, and the kernel makezImage gets stuck-Linux general technology-Linux programming and kernel information. here is the details. I used the 2.4 kernel as an example. if I want to learn what I use now, I will compile the 2.6 kernel and follow the steps given by the textbook step by step. now there are two problems.
First, it is not very Fatal. after saving make menuconfig, run the make dep command to warn that make dep is unnecessary.
X @ x-laptop :~ Linux-2.6.30.2 $ make dep
* ** Warning: make dep is unnecessary now.
The second problem is fatal. make zImage has no rules.
Case-sensitivity errors can be ruled out. I guess the system Association is not good? Maybe the kernel configuration is not set properly? Let's take a look. I can't solve it anymore. hurry up!
X @ x-laptop :~ Linux-2.6.30.2 $ make zImage

Please help me to add the following: I used ubuntu10.04 to support the three-year update. all updates are updated. Is there a problem with the gcc version?
