During linux compilation, the following error occurs: "error: the type of array elements is incomplete" -- Linux general technology-Linux programming and kernel information. For details, see the following. System: Fedora Core4

Kernel: 2.6.11.1

Error:

1. CC drivers/i2c/i2c-core.o

Solution:

Change struct i2c_msg [] In line 58,197 of include/linux/i2c. h to struct i2c_msg * msg

2, In file encoded from drivers/media/video/bttv-driver.c: 42:

Drivers/media/video/bttvp. h: 233: error: the type of the array element is incomplete.

The type is not allowed to be used before the declaration, so the change order can be passed smoothly.
