对 std：：runtime_error：：operator= 的未定义引用

问：

我在尝试链接项目时遇到问题。它给了我以下输出

[100%] Linking CXX executable ../../bin/deSimViewer
/usr/bin/ld: ../../lib/libdeViewerCore.so: undefined reference to `std::runtime_error::operator=(std::runtime_error&&)'

deSimViewer是配置了 cmake 的目标，它仅链接到 .deViewerCore

我正在做，得到以下输出（裁剪以仅显示有趣的部分）ldd deViewerCore.so

        libcusparse.so.10 => /opt/cuda/lib64/libcusparse.so.10 (0x00007efbeea42000)
        libdl.so.2 => /usr/lib/libdl.so.2 (0x00007efbeea3d000)
        libgomp.so.1 => /usr/lib/libgomp.so.1 (0x00007efbeea02000)
        libpthread.so.0 => /usr/lib/libpthread.so.0 (0x00007efbee9e1000)
        libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007efbee7f9000)
        libm.so.6 => /usr/lib/libm.so.6 (0x00007efbee6b3000)
        libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0x00007efbee699000)
        libc.so.6 => /usr/lib/libc.so.6 (0x00007efbee4d6000)

所以它与 .libstdc++.so.6

nm -C /usr/lib/libstdc++.so.6 | grep runtime_error显示存在operator=

00000000000c9290 T std::runtime_error::operator=(std::runtime_error&&)
00000000000c9240 T std::runtime_error::operator=(std::runtime_error const&)

所以我不知道这是怎么回事，也不知道为什么它没有链接。

知道可能会发生什么吗？

编辑：按照评论中的建议添加nm的输出而不进行去边角

nm libdeViewerCore.so | grep runtime_error
