尽管GNUmake表工具包有一个真正的while循环(不管这在GNUmake编程中意味着什么，它有两个或三个执行阶段)，如果需要的是一个迭代列表，有一个简单的解决方案，即interval。为了好玩，我们把数字也转换成十六进制:

include gmtt/gmtt.mk

# generate a list of 20 numbers, starting at 3 with an increment of 5
NUMBER_LIST := $(call interval,3,20,5)

# convert the numbers in hexadecimal (0x0 as first operand forces arithmetic result to hex) and strip '0x'
NUMBER_LIST_IN_HEX := $(foreach n,$(NUMBER_LIST),$(call lstrip,$(call add,0x0,$(n)),0x))

# finally create the filenames with a simple patsubst
FILE_LIST := $(patsubst %,./a%.out,$(NUMBER_LIST_IN_HEX))

$(info $(FILE_LIST))

输出:

./a3.out ./a8.out ./ad.out ./a12.out ./a17.out ./a1c.out ./a21.out ./a26.out ./a2b.out ./a30.out ./a35.out ./a3a.out ./a3f.out ./a44.out ./a49.out ./a4e.out ./a53.out ./a58.out ./a5d.out ./a62.out

#I have a bunch of files that follow the naming convention
#soxfile1  soxfile1.o  soxfile1.sh   soxfile1.ini soxfile1.txt soxfile1.err
#soxfile2  soxfile2.o   soxfile2.sh  soxfile2.ini soxfile2.txt soxfile2.err
#sox...        ....        .....         ....         ....        ....
#in the makefile, only select the soxfile1.. soxfile2... to install dir
#My GNU makefile solution follows:
tgt=/usr/local/bin/          #need to use sudo
tgt2=/backup/myapplication/  #regular backup 

install:
        for var in $$(ls -f sox* | grep -v '\.' ) ; \
        do \
                sudo  cp -f $$var ${TGT} ;     \
                      cp -f  $$var ${TGT2} ;  \
        done


#The ls command selects all the soxfile* including the *.something
#The grep command rejects names with a dot in it, leaving  
#My desired executable files in a list. 

一个简单的、独立于shell/平台的纯宏解决方案是…

# GNU make (`gmake`) compatible; ref: <https://www.gnu.org/software/make/manual>
define EOL

$()
endef
%sequence = $(if $(word ${1},${2}),$(wordlist 1,${1},${2}),$(call %sequence,${1},${2} $(words _ ${2})))

.PHONY: target
target:
    $(foreach i,$(call %sequence,10),./a.out ${i}${EOL})

如果您正在使用GNU make，您可以尝试一下

NUMBERS = 1 2 3 4
doit:
        $(foreach var,$(NUMBERS),./a.out $(var);)

哪个将生成并执行

./a.out 1; ./a.out 2; ./a.out 3; ./a.out 4;

这个答案，就像@Vroomfondel的答案一样，旨在以优雅的方式规避循环问题。

我的想法是让make生成循环本身作为一个导入的makefile，就像这样:

include Loop.mk
Loop.mk:Loop.sh
     Loop.sh > $@

shell脚本可以像你喜欢的那样高级，但可以是一个最小的工作示例

#!/bin/bash
LoopTargets=""
NoTargest=5
for Target in `seq $NoTargest` ; do
    File="target_${Target}.dat"
    echo $File:data_script.sh
    echo $'\t'./data_script.ss $Target
    LoopTargets="$LoopTargets $File"
done
echo;echo;echo LoopTargets:=$LoopTargets

生成文件

target_1.dat:data_script.sh
    ./data_script.ss 1
target_2.dat:data_script.sh
    ./data_script.ss 2
target_3.dat:data_script.sh
    ./data_script.ss 3
target_4.dat:data_script.sh
    ./data_script.ss 4
target_5.dat:data_script.sh
    ./data_script.ss 5


LoopTargets:= target_1.dat target_2.dat target_3.dat target_4.dat target_5.dat

这样做的好处是make本身可以跟踪已经生成的文件以及需要(重新)生成的文件。同样，这也允许make使用-j标志进行并行化。

为了跨平台支持，让命令分隔符(用于在同一行上执行多个命令)成为可配置的。

例如，如果你在Windows平台上使用MinGW，命令分隔符是&:

NUMBERS = 1 2 3 4
CMDSEP = &
doit:
    $(foreach number,$(NUMBERS),./a.out $(number) $(CMDSEP))

这将在一行中执行连接的命令:

./a.out 1 & ./a.out 2 & ./a.out 3 & ./a.out 4 &

正如前面提到的，在*nix平台上使用CMDSEP =;
