c++ - Wangle:/usr/local/lib/libfolly.so: 对 boost::re_detail_106000 的 undefined reference

Question

我在安装Wangle的时候遇到了如下问题。我已经安装了 Boost，但我不知道为什么。

使用 clang 而不是 gcc，删除 CMakeList.txt 中的原子检查并禁用测试，使 wangle 在 Arch 上为我构建。

目前无法使用 GCC 7 构建 (Issue) GCC 5 向我提出了与您类似的问题。

CC=clang CXX=clang cmake 。 -DBUILD_TEST=0

(上面的代码不包括您需要自己在 CMakeList.txt 中删除的原子检查!只需搜索 atomic。)
