编译/构建 MongoDB 6.0.15 Alpine Linux 3.19 / -Winterference-size 时出错

Question

我一直在尝试为 Alpine Linux 3.19 编译 MongoDB 6.0.15，这非常具有挑战性，很大程度上是因为使用了 musl 而不是 libc。

面临的错误包括：

在 src/mongo/util/aligned.h 中： 代码

src/mongo/util/aligned.h:135:77: warning: use of 'std::hardware_destructive_interference_size' [-Winterference-size]
  135 | using CacheAligned = Aligned<T, stdx::hardware_destructive_interference_size>;
Even when trying to pass the flags -mtune, -mcpu, or --param hardware_destructive_interference_size=64, the error still persists.

另一个阻碍我的错误是在编译 src/mongo/util/dns_query_posix_imp.h 时，我被告知没有引用 ‘res_nclose’、‘res_ninit’ 和 ‘res_nstatus’。我已经检查了该文件，它包含 resolv.h 的包含文件，我的系统中也有该文件。

我试过了

python3 buildscripts/scons.py DESTDIR=/usr/bin/mongod/ install-mongod CXXFLAGS="--param hardware_destructive_interference_size=64"

但是

Answer 1

您需要深入研究 SConstruct 和您的环境，以了解脱节是什么。构建系统无法使用 gcc 编译“简单文本文件”。从这里开始。 如果最终导致您的环境出现问题，您可以通过在 scons 调用中设置

CXX

来显式设置编译器路径。
