c - 制作 : How to generate list of all . c 文件，除了一个

Question

我有一个包含两个真实目标的 make 项目，一个测试套件和项目的可执行文件。

为了构建这些，我需要类似这样的规则:

testsuite: *.c (except executable.c) *.h
    clang ... *.c (except executable.c) -o testsuite

executable: *.c (except testsuite.c) *.h
    clang ... *.c (except testsuite.c) -o executable

如果可能的话，正确的语法是什么？

Answer 1

像这样的事情应该做你想做的。

# Explicitly list the sources specific to each target.
EXECUTABLE_SOURCES := executable.c
TESTSUITE_SOURCES := testsuite.c

# Filter out all specific sources from the common wildcard-ed sources.
COMMON_SOURCES := $(filter-out $(TESTSUITE_SOURCES) $(EXECUTABLE_SOURCES),$(wildcard *.c))

testsuite: $(TESTSUITE_SOURCES) $(COMMON_SOURCES)
        clang ....

executable: $(EXECUTABLE_SOURCES) $(COMMON_SOURCES)
        clang ....
