本文介绍了在makefile或CMake文件中的列表上并行迭代的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
是否可以在Makefile或CMake文件中并行循环多个列表?
Is there a way to loop over multiple lists in parallel in a makefile or CMake file?
除了AFAICT之外,我想在CMake中执行以下操作:不支持以下语法:
I would like to do something like the following in CMake, except AFAICT this syntax isn't supported:
set(a_values a0 a1 a2)
set(b_values b0 b1 b2)
foreach(a in a_values b in b_values)
do_something_with(a b)
endforeach(a b)
这将执行:
do_something_with(a0 b0)
do_something_with(a1 b1)
do_something_with(a2 b2)
我会接受CMake或Make的答案,尽管CMake将是首选。谢谢!
I would accept an answer in either CMake or Make, though CMake would be preferred. Thanks!
推荐答案
在这里,您要去:
set(list1 1 2 3 4 5)
set(list2 6 7 8 9 0)
list(LENGTH list1 len1)
math(EXPR len2 "${len1} - 1")
foreach(val RANGE ${len2})
list(GET list1 ${val} val1)
list(GET list2 ${val} val2)
message(STATUS "${val1} ${val2}")
endforeach()
