我正在测试distcc，我发现这个教程很容易理解，我应该说我能够编译llvm使用CMake + Ninja和CMake + Makefiles使用distcc并且docker没有问题。因为我对 Makefiles 特别感兴趣，所以我查看了生成的文件，CMake + Ninja我所看到的只是distcc作为前缀添加到编译器（例如distcc /usr/bin/gcc）。所以我想，如果我只使用 Makefiles 创建一个小项目，我可能会添加distcc并且事情会神奇地工作。好吧，看起来我错过了一些东西，因为我得到的只是：

$ ./mk.sh image

make[1]: Entering directory '/home/user/sandbox/distcc-makefiles'

通过运行llvm示例，我放弃了所有docker连接和distcc配置问题，我尝试在互联网上搜索任何想法/示例，但大多数人使用CMake的不是我的情况。欢迎提出建议，我的演示项目基于我正在从事的真实项目，所以基本上就是Makefile这样。

我不知道我错过了什么...

启用调试消息（带$ export DISTCC_VERBOSE=1）后，我发现它distcc实际上在服务器中编译，但编译失败，这就是它在本地重试的原因。

它失败了，因为我使用外部文件来保留其他选项（请参阅gcc @file）并且distcc不将其解释为文件，而是基本上作为字符串。这就是编译失败和distcc回退的原因。

日志检查

作为参考，distcc日志如下所示（分为部分进行进一步说明）：

据我了解，SECTION A找到远程服务器，SECTION B打开与服务器的连接，SECTION C发送命令以在服务器中运行（包括编译选项和要编译的文件），SECTION D获取结果，E 部分分析结果并决定下一步做什么。如您所见，这是错误：

distcc[13039] (dcc_x_token_string) send string '@_out/Release/Boot/Main.o.via'
distcc[13039] (dcc_x_token_int) send ARGV00000002

要查看编​​译错误的输出，请在上面定义这些环境：

export DISTCC_VERBOSE=1
export DISTCC_SAVE_TEMPS=1
export DISTCC_FALLBACK=0

另见man distcc或https://linux.die.net/man/1/distcc

当前的 distcc 维护者，

我强烈建议MASQUERADE按照 distcc 手册页中的说明使用。
