Question

Compiling the following code on Linux

#include <stdio.h>

void main() {
  printf("Hello World\n");
  return;
}

using icc version 15.0.0

icc -no-cxxlib -no-gcc-include-dir test.c

produces a dynamic executable that is linked against glibc:

ldd ./a.out 
    linux-vdso.so.1 =>  (0x00007ffc601b6000)
    libm.so.6 => /lib64/libm.so.6 (0x00000038f0c00000)
    libc.so.6 => /lib64/libc.so.6 (0x00000038efc00000)
    libdl.so.2 => /lib64/libdl.so.2 (0x00000038f0400000)
    /lib64/ld-linux-x86-64.so.2 (0x00000038ef800000)

The same is true for Fortran using ifort version 15.0.0 and the corresponding code

program test
  print *,'Hello world'
end program

compiled with

ifort -no-cxxlib -no-gcc-include-dir test.F90

Again, the resulting library is linked against glibc:

ldd ./a.out 
    linux-vdso.so.1 =>  (0x00007fff483da000)
    libm.so.6 => /lib64/libm.so.6 (0x00000038f0c00000)
    libpthread.so.0 => /lib64/libpthread.so.0 (0x00000038f0000000)
    libc.so.6 => /lib64/libc.so.6 (0x00000038efc00000)
    libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00000038f2c00000)
    libdl.so.2 => /lib64/libdl.so.2 (0x00000038f0400000)
    /lib64/ld-linux-x86-64.so.2 (0x00000038ef800000)

tl;dr; Do the Intel compilers provide their own C library on Linux? If yes, how can I link against it?

I know that for the Windows version, there is (was?) an alternative C library shipped with the compiler/runtime libraries. However, I couldn't find any library of that kind shipped by Intel on Linux.

英特尔不提供任何glibc或libstdc ++。在几年前的itanium开始时，有dinkumware，而intel提供MIC与MPSS的库。对于Windows，需要Microsoft SDK。 IIRC Icc 15.0通常在路径上运行g ++ 4.7或4.9。

Does Intel provide its own C library on Linux?
