c++ - Exclude source file in compilation using Makefile

Question

Is it possible to exclude a source file in the compilation process using wildcard function in a Makefile?

Like have several source files,

src/foo.cpp
src/bar.cpp
src/...

Then in my makefile I have,

SRC_FILES = $(wildcard src/*.cpp)

But I want to exclude the bar.cpp. Is this possible?

If you're using GNU Make, you can use filter-out:

SRC_FILES := $(wildcard src/*.cpp)
SRC_FILES := $(filter-out src/bar.cpp, $(SRC_FILES))

Or as one line:

SRC_FILES = $(filter-out src/bar.cpp, $(wildcard src/*.cpp))
