Finally, C ++ code porting was introduced to bootloader. The only achievement was familiarity with makefile. Some factory companies could not afford to be hurt. Every time they had to do something to meet the needs of factory-side testing, in order to be able to meet the requirements of the factory for testing in Boot, after discussion with the chip company, only C ++ can be obtained to boot, it is really a second decision that boot will eventually ac
When the make command executes, a makefile file is required to tell the make command how to compile and link the program.First, we use an example to illustrate Makefile's writing rules. In order to give everyone a perceptual knowledge. This example comes from the GNU Make manual, in which we have 8 C files, and 3 header files, and we're going to write a makefile to show how the Make command compiles and lin

Here are five steps to compile the Linux makefile:compile total of five parts1. Setting up the compilation environment set compile environment2. Get the source file to compile and convert the source file to the destination file (source and destination files) source to obj3. Compile the file as the target file objing4. Link the target file to an executable file or (packaged as) a dynamic library, or a static library linking5. Other aspects such as cleanThe following is a simple
Some of the basic rules of makefile are not mentioned. Some makefiles use a mix of Linux commands and functions, sometimes confusing.
The following is an example:
Example 1 (using Linux commands ):

Among them, the most important file is: program_template.mk.

Makefile variable assignment, makefile assignment
When defining the value of a variable, we can use other variables to construct the value of the variable. There are two methods in Makefile to define the value of the variable.First, let's look at the first method, that is, simply using the "=" sign, on the left side of "=" is the variable, and on the right side i
