.SECONDARY用于GNU Make的模式规则 [英] .SECONDARY for a pattern rule with GNU Make

问题描述

我想使用GNU Make的特殊目标.SECONDARY指定在作为中间文件创建时，不应删除特定模式规则的结果. .PRECIOUS使用模式，但奇怪的是，.SECONDARY无法使用.我不想使用.PRECIOUS，因为我确实希望在Make被信号中断的情况下删除该文件，或者当该命令与.DELETE_ON_ERROR结合使用时，该命令返回非零退出状态.有什么建议吗?

I want to use the special target .SECONDARY of GNU Make to specify that the results of a particular pattern rule should not be deleted when created as a intermediate files. .PRECIOUS works with patterns, but oddly enough, not .SECONDARY. I don't want to use .PRECIOUS, because I do want the file to be deleted in the case that Make is interrupted by a signal, or the command returns a non-zero exit status when used in combination with .DELETE_ON_ERROR. Any suggestions?

推荐答案

您可以在没有先决条件的情况下使用.SECONDARY，这会将所有中间目标设置为SECONDARY.

You can use .SECONDARY with no prerequisites, this will set all intermediate targets behave as SECONDARY.
