我在 Raspberry Pi 上做了很多编译工作。我正在考虑使用 distcc 来加快速度。
我关注了这篇文章：https ://www.kvaser.com/developer-blog/building-raspberry-pi-using-distcc/
这允许我将 Arch Linux VM 配置为交叉编译器主机，并将我的 Raspberry Pi 配置为客户端。
就网络而言，该设置似乎有效。我可以tcpdump在 Arch 上使用来确认make在 Pi 上运行时，服务器的distcc端口 ( 3632) 会收到大量请求。
该设置似乎也适用于使用交叉编译器。我的Arch Linux 没有安装本机、、、、c++或二进制文件。在没有设置指向交叉编译器的情况下，Pi 抱怨它无法按预期找到二进制文件。cccppg++gccPATHgcc
我看到的问题是，当我尝试编译时Python 3.7.11，我几乎在运行 make 后立即得到了这个：
gcc -pthread -c -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -std=c99 -Wextra -Wno-unused-result -Wno-unused-parameter -Wno-missing-field-initializers -Wno-cast-function-type -Werror=implicit-function-declaration -I. -I./Include -DPy_BUILD_CORE -o Parser/tokenizer.o Parser/tokenizer.c

没有distcc，Python 在 Pi 上编译得很好——它只需要很长时间。
主机（Arch Linux）是否缺少一些编译 Python 所需的库？我的印象是它不需要任何东西。
问题是否可能是我的 Raspberry Pi 使用内核5.4.51-v7+，而工具链https://github.com/raspberrypi/tools.git似乎只支持arm-rpi-4.9.3-linux-gnueabihf？
我很迷失在这里。任何帮助，将不胜感激。
更新：似乎 distcc 正在工作，但编译失败。也许这解释了它：
在 Debian Buster 中，gcc 编译器和 glibc 已更新到 8.3 版。git://github.com/raspberrypi/tools.git 中的工具链仍然基于旧的 gcc 6 版本。这意味着使用 git://github.com/raspberrypi/tools.git 会导致很多编译错误。
这将需要进一步研究。
