Question

希望这是关于制作模式规则的基本问题：我想在规则的先决条件中不止一次使用通配符，即在我的Makefile中有

data/%P1.m: $(PROJHOME)/data/%/ISCAN/%P1.RAW
        @echo "  Writing temporary matlab file for $*"
        # do something

data/%P2.m: $(PROJHOME)/data/%/ISCAN/AGP2.RAW
            @echo "  Writing temporary matlab file for $*"
            # do something

在这个例子中，当通配符％为AG时，我尝试调用make。两个文件$（PROJHOME）/data/AG/ISCAN/AGP1.RAW和$（PROJHOME）/data/AG/ISCAN/AGP2.RAW存在。我尝试以下make命令并获得此输出：

[jshen@iLab10 gender-diffs]$ make data/AGP1.m
make: *** No rule to make target `data/AGP1.m'.  Stop.

[jshen@iLab10 gender-diffs]$ make data/AGP2.m
Writing temporary matlab file for AG, part 2...

[jshen@iLab10 gender-diffs]$ ls data/AG/ISCAN/AG*
data/AG/ISCAN/AGP1.RAW  data/AG/ISCAN/AGP2.RAW

如何在第一个make规则中实现同一个通配符的多个实例？

Answer 1

这似乎有效：

.SECONDEXPANSION:    
data/%P1.m: $(PROJHOME)/data/$$*/ISCAN/$$*P1.RAW
            @echo "Writing temporary matlab file for $*, part 1..."

makefile模式规则：单个通配符，先决条件中的多个实例
