Check-symlink Supports the manual -L (-check-symlink-times) flag.
For example: foo : bar/lose cd D) gobble F).Phony targets are makefile also useful in conjunction with recursive invocations of make (see Recursive Use of make ).To test for an empty value, use manual ifeq (foo.Therefore, you makefile must use Unix-style slashes in these cases.This odd behavior is only for compatibility with other implementations of make you should avoid using it).For example, manual making foo from foo.Note that this is different from how unmatched wildcards behave in rules, where they are used verbatim rather than ignored (see Wildcard Pitfall ).There is a script called mkinstalldirs which is convenient for this; you can find it in the Gnulib package.See Chains of Implicit Rules.This practice is generally manual cleaner than that of somehow appending the prerequisites to the end of the main makefile as has been makefile traditionally done with other versions of make.And finally, you should set the following makefile variable: srcdir The directory for the sources being compiled.The implementations of these make functions may make use of the gmk_expand and gmk_eval routines to perform their tasks, then optionally return a string as the result of the function expansion.O, the stem is test.It does not expand the variable to see if that value is nonempty.You can list the target pattern of an implicit rule (such.o) as a prerequisite of the special target.precious to preserve intermediate files made by implicit rules whose target patterns match that files name; see Interrupts. To print the data base of predefined rules crack and hacked variables, use make -p -f /dev/null.
Oldincludedir The directory for installing #include header files for use with compilers other than GCC.
12.1 GNU Guile Integration GNU make may be built with support for GNU Guile as an embedded extension language.
(Wildcards and full archive members (see Archives ) are allowed here crack too.) A target is out of date if it does not exist or if it is older than any of the prerequisites (by comparison of last-modification times).With the type line, output from each line in the recipe is grouped together.When you override a crack variable with a command line argument, you can define either a recursively-expanded variable or a simply-expanded variable.H, and hacked is not at all asphalt like the pattern rule:.o:.c foo.GNU make will check this and fail before invoking func_ptr if the function was invoked with too few arguments.Pattern-specific variables which result in the same stem length are considered in the order in which they were defined in the makefile.References to recursively-expanded variables within a variable name are re-expanded in the usual fashion.However, if you use the value of objects in a target or prerequisite, wildcard expansion will take place there.An hacked example of appropriate use is to avoid including.d files during clean rules (see Automatic Prerequisites so make wont create them only to immediately remove them again: sources foo.You could, for example, maintain multiple output files at the same time by choosing a symbol for each one and using it as the key to a hash table, where the value is a port, then returning the symbol to be stored in a make.(sort list) Sort the words in list lexicographically, removing duplicates.
Distclean Delete all files in the current directory (or created by this makefile) that are created by configuring or building the program.
As an example:.secondexpansion: foo: bar foo foz: fo: bo oo: * When the implicit rule is tried for gnu makefile manual pdf target foo, expands to bar, expands to bar boo, also expands to bar boo, and * expands.
