用另一个makefile包裹GNU makefile [英] Wrapping GNU makefile with another makefile

问题描述

这是在问题之后.

我有Makefile.real(来自上一个问题的Makefile):

I have Makefile.real (Makefile from prev question):

all: a b

a:
        echo a
        exit 1


b:
        echo b start
        sleep 1
        echo b end

现在我想创建Makefile，它是Makefile.real的简单包装:

Now I want to create Makefile that is simple wrap of Makefile.real:

• 它使用Makefile.real调用make并具有与被调用相同的参数
• 它应该显示错误消息ID Makefile.real失败 这是我的目标-在并行make末尾显示错误消息 (请参阅问题)

• It calls make with Makefile.real with the same args as it was called
• It should print error message id Makefile.real fails This is my goal - print error message in the end of parallel make (see question)

因此以下命令应以错误消息终止:

Therefore following commands should terminate with error message:

make -j1 a b (1)
make -j2 a b (2)

我怀疑Makefile应该接近:

%:
      $(MAKE) -f Makefile.real $(MAKECMDGOALS); \
      res=$$?; if [ $$res != 0 ]; then echo "Failed!!!"; fi; exit $$res

问题是目标'％'对于a和b对于(2)都会被调用两次.

The problem is that target '%' will be called twice for a and b for (2).

有什么想法吗?

推荐答案

这是我最后的解决方法

ifneq ($(REAL_MAKE),1)
# run_make will be called once (it's .PHONY target), 
# even if make is called with several targets
%: run_make
        @:

.PHONY: run_make
run_make:
        $(MAKE) $(MAKECMDGOALS) REAL_MAKE=1; \
        if [ $$? -ne 0 ]; then               \
            echo "*** Error ***" >&2;        \
            exit 1;                          \
        fi

else  # REAL_MAKE defined (actual makefile)

### HERE comes original make we want to wrap ###

endif  # # REAL_MAKE defined (actual makefile)
