1. Compile the command path First: With overlay: Export path=/home/chunyun/yocto/bitbake/bin/: $PATH If write directly: Export path=/home/chunyun/yocto/bitbake/ The Bin/path path becomes the Bitbake execution path, and other SH commands cannot be used, such as CD, VIM, etc.
2, compile time: Bitbake FIRSTRECIPE-VDD
This allows you to see what steps are in each step. Where the error occurred. Good to correct.
3. Error:no recipe files to build, check your Bbpath and bbfiles?
No path is set for Bbpa
A "list" is a value that contains a sequence of multiple words. The term "list value" refers to the list itself (which, as a value, can be saved in a variable, passed to a function)list [' AA ', ' BB ', ' cc ', ' DD '] is a simple listing1.

In an Oracle database, rowid is unique and identifies the file, block, and row to be recorded.On Repeated Records, the contents of all columns may be the same, but their rowidIt is different, so I only need to delete the largest rowid of the Repeated Records.Let's get started with a bunch of things.
1. Delete duplicate rows

Finally, I began to study VC with peace of mind. First of all, I had been troubled by the cbutton class of VC, which had no beautification function at all. I had to write my own code if I wanted to change the color font or something, envy yourself when you are working on VB. However, I have learned a lot about my exploration over the past two days. The following is a self-encapsulated button class with the foreground color, background color, Font, and background color and background image of the

Buffer Basics
There are several flag bits used to operate the Buffer Zone
Capacity: The buffer size (byte). Read and Write values remain unchanged.Position: the location where the next byte is read and written. Note: position is always less than limit.Limit: when writing (limit = capacity), when reading (position of the last write)Mark: the initial value is-1. You can call reset () to return to the mark position.

Array operation problem $ bb = array ("id" => "1", "wo2" => "8 ")
$ Aa = array ("id" => "1", "wo2" => "5", "wo3" =>" 3 ")
How to change the two arrays to $ cc = array ("id" => "1", "wo2" => "8", "wo3" =>" delete ")
Because wo2 aa is smaller than bb, how is it 8? On the contrary, it is 5 wo3. because bb does not have all the delete operations.
