Include another makefile. See Including Other Makefiles. override variable-assignment. Define a variable, overriding any previous definition, even one from the command line. See The override Directive. export. Tell make to export all variables to child processes by default. See Communicating Variables to a Sub-make. export variable export. To pass down, or export, a variable, make adds the variable and its value to the environment for running each line of the recipe. The sub- make, in turn, uses the environment to initialize its table of variable values. See Variables from the Environment.  · This manual describes GNU make, which was implemented by Richard Stallman and Roland McGrath. Development since Version has been handled by Paul D. Smith. GNU make conforms to section of IEEE Standard (POSIX.2). Our examples show C programs, since they are most common, but you can use makeFile Size: KB.

Writing documentation with Roxygen2. To add documentation to an R package, you need to create a subdirectory " man " containing a set of files, one per function, in a special R Documentation format .Rd). These will be the source for the documentation for each function; R processes them to create plain text, PDF, and HTML versions. Use export for recursive make. The export directive takes a variable and makes it accessible to sub-make commands. In this example, cooly is exported such that the makefile in subdir can use it. Note: export has the same syntax as sh, but they aren't related (although similar in function). use `export' by itself to export variables by default, variables whose names contain characters other than alphanumerics and underscores will not be exported unless specifically mentioned in an `export' directive. The behavior elicited by an `export' directive by itself was the default in older versions of GNU `make'. If your makefiles depend on.

GNU Make Manual. Free Software Foundation. last updated Janu. This manual (make) is available in the following formats: HTML (K bytes) - entirely on one web page. HTML - with one web page per node. HTML compressed (K gzipped characters) - entirely on one web page. Include another makefile. See Including Other Makefiles. override variable-assignment. Define a variable, overriding any previous definition, even one from the command line. See The override Directive. export. Tell make to export all variables to child processes by default. See Communicating Variables to a Sub-make. export variable export. GNU Make manual says (in ) "Except by explicit request, make exports a variable only if it is either defined in the environment initially or set on the command line", and then says that the export and unexport keywords can be used to control that.
