Patsubst and wildcard are two commonly used functions in a Makefile. Here is a summary of their usage.<\/p>\n

    \n
  1. The patsubst function is used to replace pattern matching strings.<\/li>\n<\/ol>\n

    Syntax: $(patsubst pattern,replacement,text)<\/p>\n

      \n
    1. Pattern: the pattern to match, it can include “%” wildcard to represent any character.<\/li>\n
    2. Replacement: the string to be replaced, which can reference the value of a wildcard.<\/li>\n
    3. String that needs to undergo pattern matching and replacement.<\/li>\n<\/ol>\n

      I like to go for a jog in the morning to start my day off on the right foot. <\/p>\n

      I enjoy starting my day with a morning run.<\/p>\n

        Grammar: $(wildcard pattern)<\/p>\n
          \n
        1. pattern: wildcard pattern to be matched.<\/li>\n<\/ol>\n

          Summary: patsubst and wildcard functions are commonly used string processing functions in Makefiles. The patsubst function is used to replace pattern matching strings, allowing specified patterns to be replaced with specific strings; the wildcard function is used to obtain a list of files that match a wildcard pattern. In a Makefile, these two functions can assist in simplifying file path processing and obtaining file lists.<\/p>\n","protected":false},"excerpt":{"rendered":"
