It is composed of common strings and can be very complex. special characters are often used to indicate characters in a range, repeated occurrences, or context. F
Implied rules————When we use makefile, there are some things we will use very often, and the use of very high frequency, for example, we compile the source program C/s + + for intermediate target files (Unix is [. o] File, under Windows is [. obj] file). This chapter deals with some of the "hidden", previously agreed upon makefile rules that we do not need to write again.The "implied rule" is also a convent

Pattern rules
Pattern rules are similar to normal rules. In the pattern rule only, the target name needs to contain a pattern character "%" (one), and a target containing the pattern character "%" is used to match a filename, and "%" can match any non-empty string.

Makefile is important.What is makefile. Maybe a lot of WINODWS programmers don't know this, because the Windows IDE does the work for you, but I think that to be a good and professional programmer, Makefile still have to understand. It's like there are so many HTML editors now, but if you want to be a professional, you still have to understand the meaning of the HTML logo. Especially in Unix software compiled, you can not write makefile, will not write makefile, from a side to explain whether a
Rules control packet filtering by providing the firewall with instructions on what to do with packets from a source, to a destination, or to a specific protocol type. By using the special commands provided by the Netfilter/iptables system iptables, these rules are established and added to the chain within the specific packet filtering table of the kernel space. The general syntax for the command to add/remo

Any HTML element can be a CSS1 selector. A selector is just an element that points to a special style. For example

code.html {
Writing rules————The rule contains two parts, one is a dependency, and the other is the method that generates the target.In Makefile, the order of the rules is important because, in makefile, there should only be one final goal, and the other targets are associated with this goal, so make sure to know what your ultimate goal is.In general, there may be many goals defined in makefile, but the goal in the fir
