meson-build - Prefix all sources with src/ in Meson

Question

Relative to my project root where meson.build is located, all of my source files are under src/.

Is it possible to specify these source files in meson.build in a way that wouldn't force me to prefix them all with src/, given that that's somewhat redundant?

Answer 1

不需要为源文件添加前缀，因为介子提供了特殊功能：files()，它生成“记住”子目录的文件数组对象。例如，在根meson.build中，您可以拥有：

subdir('src')
subdir('src_more')
exe = executable('test', sources)

在src/meson.build：

sources = files('a1.c', 'a2.c')

在src_more/meson.build：

sources += files('b1.c', 'b2.c')

Answer 2

你真的应该放一个meson.build文件src/并在那里创建列表。

Answer 3

您实际上可以使用foreach语句“构建”一组文件：

raw_sources = [
    'foo.cpp',
    'foomanager.cpp',
    'foofactory.cpp'
]
sources = []

foreach file : raw_sources
    full_path = join_paths('src', file)
    sources += files(full_path)
endforeach

现在源包含具有所需前缀的文件。
