Question

当我尝试在Ubuntu Trusty上构建Plasma5时，我遇到了与eglibc 2.19相关的问题。

/usr/lib/x86_64-linux-gnu/libc_nonshared.a(lstat64.oS): In function ``lstat64': (.text+0xc): undefined reference to ``__lxstat64'

我不知道如何解决这个问题。感谢。

附加-v到g ++和ld，得到： COLLECT_GCC=/etc/alternatives/g++ COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-linux-gnu/5/lto-wrapper Target: x86_64-linux-gnu Configured with: ../src/configure -v

我遇到了同样的问题，试图做同样的事情。我不知道这是否是一个很好的解决方案，但我找到了三种方法来解决这个问题。

运行编译命令并添加＆＃34; /usr/lib/x86_64-linux-gnu/libc_nonshared.a"对它
运行编译命令并添加＆＃34; -lc＆＃34;对它
如果您使用kdesrc-build，那么最佳解决方案是将选项添加到.kdesrc-buildrc中的baloo模块中，如下所示：
```
options baloo 
    cmake-options -DCMAKE_CXX_FLAGS="-lc" 
end options
```

在一些篮球和障碍之后，我能够在Ubuntu 14.04上构建和运行Plasma 5，并且可能会写一个如何做到这一点的指南。

eglibc中的__lxstat64在哪里？
