c++ - 链接器无法找到 __assert_fail

Question

我正在尝试构建一个使用 boost 的库，虽然该库编译正常，但它遇到了一个我不理解的奇怪的链接器错误。我构建并安装了 Boost 1.54(也尝试了 1.52)，一切顺利。

它声称无法找到 __assert_fail，我认为它是标准库的一部分。我试图在 64 位中构建所有内容。我在 Fedora 16 上，使用 gcc 4.6.3

有什么想法吗？

几年后，在不同的 Fedora (29)、更高版本的 boost、gcc 等上。我遇到了同样的问题。更多的是靠直觉而不是理解我摆脱了 gcc visibility pragmas(即我注释掉了所有的: #pragma GCC 可见性推送({whatever})... #pragma GCC 可见性弹出)成功了——编译、链接并成功运行。
