我完全遵循了该指示：

$ mkdir $HOME/src
$ cd $HOME/src
$ git clone git://sourceware.org/git/glibc.git
$ mkdir -p $HOME/build/glibc
$ cd $HOME/build/glibc
$ $HOME/src/glibc/configure --prefix=/usr
$ make

但是在最后一个命令“make”期间，我收到以下错误（仅给出输出的结尾）：

make[3]: Leaving directory '/home/denis/src/glibc/elf'

I came across an elegant line of reading a binary file into a vector like this (that works):

        std::ifstream ifs("myfile.bin", std::ios::binary);
        std::vector<char> buffer(std::istreambuf_iterator<char>(ifs), {});

Instead since I want my vector to be a shared pointer I write:

        std::ifstream ifs("myfile.bin", std::ios::binary);
        auto sp = std::make_shared<std::vector<char>>(std::istreambuf_iterator<char>(ifs), {});

I.e just pass the vector constructor arguments to make_shared (as I usually do to create any shared pointer of any objects). But I get: error: no matching function for call to 'make_shared'?

Detailed output:
