conan graph build-order-merge¶
$ conan graph build-order-merge -h
Migration: Successfully updated settings.yml
usage: conan graph build-order-merge [-h] [-f FORMAT] [--out-file OUT_FILE]
[-v [V]] [-cc CORE_CONF] [--file [FILE]]
[--reduce]
Merge more than 1 build-order file.
options:
-h, --help show this help message and exit
-f FORMAT, --format FORMAT
Select the output format: json, html
--out-file OUT_FILE Write the output of the command to the specified file
instead of stdout.
-v [V] Level of detail of the output. Valid options from less
verbose to more verbose: -vquiet, -verror, -vwarning,
-vnotice, -vstatus, -v or -vverbose, -vv or -vdebug,
-vvv or -vtrace
-cc CORE_CONF, --core-conf CORE_CONF
Define core configuration, overwriting global.conf
values. E.g.: -cc core:non_interactive=True
--file [FILE] Files to be merged
--reduce Reduce the build order, output only those to build.
Use this only if the result will not be merged later
with other build-order
如 conan graph build-order
命令所述,有两种类型的顺序:recipe
和 configuration
。只有相同类型的构建顺序才能合并,否则命令将返回错误。
请注意,只有未通过 --reduce
缩减的构建顺序才能合并。
合并不同输入文件的结果也可以使用 conan graph build-order-merge --reduce
参数进行缩减,其行为相同,即只保留需要从源代码构建的元素。
当合并 2 个或更多“构建顺序”文件时,合并结果会包含一个 profiles
部分,如下所示:
"profiles": {
"build_order_win": {
"args": "-pr:h=\"profile1\" -s:h=\"os=Windows\" ..."
},
"build_order_nix": {
"args": "-pr:h=\"profile2\" -s:h=\"os=Linux\" ..."
}
}
其中 build_order_win
和 build_order_nix
是用作合并输入的“构建顺序”文件名,它们将在构建顺序中每个 package
的 filenames
字段中被引用。这样,在构建多种配置时,更容易获取构建构建顺序中特定软件包二进制所需的命令行参数。
