makefile regular expression
If I understood your question correctly, you have a bunch of *.source files, and want a rule that turns each into a *.target file, while picking two sub-strings from whatever the * expands to. Why not pick the stem in $* apart at the underscore? Here',.c.o: declares a simple pattern rule that matches any file ending with .c and defines the same name, but with .o as the target. $* is an automatic make variable and expands to the matched part of the pattern. If it matched main.c , $* will be main . $<, Use regex character class. if [[ "$$INSTALL_GLOBALS" =~ ^[Yy]$ ]]. ^ in regex asserts that we are at the start and $ asserts thta we are at the end of a line. [yY] matches a single character whether it may be capital Y or small y ., Do you really need a regex? make 's built-in functions can do this as well. ALL_SRCS := $(wildcard *.c) SRCS := $(filter-out ttem_endian_port%.c, $(ALL_SRCS))., To do it in GNU make, you can use one of two different "metaprogramming" models supported by GNU make: Auto-generated include files. In your main makefile, add -include generated.mk then write a makefile rule with the target generated.mk (proba, The relationship is no closer than that make expects to be supplied with a $(SHELL) that is sufficiently close to /bin/sh in certain respects. On Windows, many people use cmd.exe . You can always use the $(shell) function to invoke any utility you have i,Makefiles always interpret $ sequences before executing commands, disregarding any quoting. In order to escape $ in a Makefile, write it as $$ - that will result in a single $ in the command. ,case `uname -m` in i?86) echo "CFLAGS += -march=i486 -mtune=native" > configparms ;; esac. But I need to do this in makefile for a particular target. I have not found a method to make an if condition with a regular expression. I tried this: i,-+ doesn't have any special meaning. Also, there's nothing wrong with GNU Make, I suppose. The expressions probably does match even in the first case, but the thing is probably that either. you call make jslnit when a file jslint already exists in,The prerequisites likewise use ' % ' to show how their names relate to the target name. Thus, a pattern rule ' %.o : %.c ' says how to make any file stem .o from another file stem .c . Note that expansion using ' % ' in pattern rul
