3rd 方库在高山上构建时抱怨类型
3rd party library complains about types when building on alpine
我正在尝试在 alpine 构建容器上构建 libnfnetlink 的静态版本。它使用通常的 autogen->configure->make->make install 路线，但出于某种原因，它在 make 阶段抱怨未知类型（u_int8_t、u_int16_t 等）

我不知道问题出在哪里。配置部分正确地识别出我在 sys/types.h 中定义了未知类型，但是当我查看 src/.deps 文件夹时，我没有看到它列在 PLO 文件中。
如果我 运行 在 centos 7 或 8 容器中执行相同的步骤，它会按预期工作。我在 centos 和 alpine 之间的配置阶段看到的唯一区别是在 centos 上它有这些额外的行：
checking how to run the C preprocessor... gcc -E
checking for ANSI C header files... yes
我对 autoconf/libtool 的了解还不够，无法对此进行调试，或者我应该查看的地方，或者这是否是问题所在。从所提供的信息来看，是否有任何明显错误或是否有其他我需要遵循的阶段（未记录）？
看来我可以回答我自己的问题了。上周我遇到问题时使用的是最新版本的 libnfnetlink (1.0.1)。今天发布了一个新版本 (1.0.2)，其中发布了 9 年的修复，其中之一是不进行我遇到问题的转换，例如__16 -> u_int16_t.
现在所有构建都很好（并提醒自己，始终检查 master 分支的历史记录）
