gn:未解决的依赖关系

Question

我正试图在Ubuntu22.04上构建Chromium。我克隆了git，检出了102.0.5005.59分支，将depot_tools目录添加到PATH中，然后运行

fetch --nohooks chromium
./build/install-build-deps.sh --no-chromeos-fonts
./build/install-build-deps-android.sh --no-chromeos-fonts
gclient runhooks

然后，我试图通过运行gn args out/Default并设置

is_debug = false
is_clang = true
symbol_level = 2
dcheck_always_on = false
is_component_build = false
target_os = "android"
target_cpu = "arm64"
blink_symbol_level = 0
v8_symbol_level = 0
ignore_elf32_limitations = true

作为构建参数。然而，这失败了

奇怪的是，如果我对103.0.5060.22分支做同样的事情，那么一切都会很完美。我遗漏了什么？

看起来你错过了所有的第三方依赖关系，铬编译所需的。在签出或切换到铬的另一个分支/版本/标记之后，您应该运行以下命令，因为每个分支/版本/标记可能有不同版本的第三方依赖关系：

gclient sync

现在开始编译过程。
