# Retrieves a host part of the given string (without port). # Param: # 1. String to parse in form ‘host[:port]’. host = $(firstword $(subst :, ,$1)) # Returns a port (if any). # If there is no port part in the string, returns the second argument # (if specified). # Param: # 1. String … Read more
I also just stumbled over that problem when compiling MonetDB on my Linux machine. Here is the solution/workaround that worked for me: Always make clean after ./configure. In your example you should be able to do: ./configure –prefix=/root/build && make clean && make && make install I found the solution in a discussion on an … Read more
If you define the target .SILENT:, then make will not echo anything. It’s usually best to guard the definition, so you can easily turn it off: ifndef VERBOSE .SILENT: endif Now by default, make will print nothing, but if you run make VERBOSE=1, it will print. Note that despite the statement in the manual claiming … Read more
Try using target-specific variables. A target-specific variable is declared like this: TARGET: VAR := foo # Any valid form of assignment may be used ( =, :=, +=, ?=) Now when the target named TARGET is being made, the variable named VAR will have the value “foo”. Using target-specific variables, you could do this, for … Read more
It’s an old-fashioned suffix rule. The more up-to-date way to do it is to use a pattern rule: %.o : %.c
It’s a recursive invocation of make itself, forwarding the -t, -n and -q options. This makes sense: you want the nested make invocations to run with these options as well.
Errors in Recipes (from TFM) To ignore errors in a recipe line, write a – at the beginning of the line’s text (after the initial tab). So the target would be something like: moveit: -mv foo.o ../baz
If really all targets are PHONY, this is a bit pointless. make is meant for “do what is necessary to update my output“, and if the answer to what is necessary? is always the same, simple scripts would do the same job with less overhead. That being said, I could imagine a situation where all … Read more
A make file can have any name. The -f option of make is used to specify which file to use: make -f foobar You can even use -f several times: make -f foo -f bar In which case make processes the files in order (or, equivalently, concatenates the files and processes the result). makefile and … Read more
Use sort and dir functions together with wildcard: DIRECTORY = $(sort $(dir $(wildcard ../Test/*/))) From GNU make manual: $(dir names…) Extracts the directory-part of each file name in names. The directory-part of the file name is everything up through (and including) the last slash in it. If the file name contains no slash, the directory … Read more
