Libc.so.6/glibc cross compilation

Different versions of the system libc.so.6 Link library libc Libraries are different , For example ubuntu18 yes libc-2.27.so,ubuntu20 It is libc-3.31.so.x86_64 The library of the platform is easy to download , Source code compilation is also relatively simple , Don't say , Here is the cross compilation method , And the problems that I have .

Official website glibc Download address of source code of different versions ：

http://mirrors.nju.edu.cn/gnu/libc/

I made it up glic-2.30 The library of ：

https://download.csdn.net/download/lifei_0001/12741852

Correct compilation configuration ：

../glibc-2.30/configure --host=arm-linux-gnueabihf --build=i686-pc-linux-gnu --prefix=/home/lf/source/glibc30

Install the required dependencies before compiling ：

sudo apt-get install autoconf libtool automake

Problems encountered during compilation ：

1. configure: error: Hurd headers not installed or too old

reason ：--host=arm-linux-gnueabihf- Wrong parameter , An extra “-”.

2.gawk bison  not installed or too old

reason ： This is really not installed .sudo apt-get install gawk bison

3. echo $LD_LIBRARY_PATH

*** LD_LIBRARY_PATH shouldn't contain the current directory when
*** building glibc. Please change the environment variable
*** and run configure again.

First set the value of this variable to null . At present shell Input directly in LD_LIBRARY_PATH=, And then go back

 

Why not destroy the system source environment , And can use the heart glibc?
