我有一个makefile，我想添加一个新目标，该目标可以读取.txt文件的特定行并从$ 4开始执行该过程。
我已经运行了代码，并使用URL中的图像制作了数据库并进行了转换（$ 2和$ 3）。
顺便说一句，如果您认为这样做不是一种合理的方法（传递特定的输入并收集相应的输出），请让我知道如何以一种合理的方式进行？

我不知道这是否对您有帮助，但是您似乎还是在重新思考您的问题。您的makefile看起来至少在远程进行某种构建管理。 （请注意，您可以使用模式来编写规则，但是您似乎要针对不同的目标。）对makefile的以下重写使用了GNUmake table toolkit，看起来很适合您的目的：
include gmtt/gmtt.mk
# Direct definition of the table in the file:
# define IMAGES :=
# 2

# Rule definition - no need to call $(eval)
# Use the function `map-select` which applies a function on each selected line of a table. Syntax is $(call map-select,_column-numbers_,_table_,_where-clause_,_mapping-function_)
# We select columns one and two of the table. Where-clause is always true (t). Function is calling IMAGE_BUILD_RULES with the selected columns enumerated as $1,$2,$3,etc. - this parameter must be quoted ($$)

引用的文件imagelist.txt必须看起来像这样：
