[How to solve?]

[Step 1] 해당 버전이 있는지 check

  $ strings /lib/x86_64-linux-gnu/libXXX.so.6 | grep GLIBC_
  GLIBC_2.2.5
  GLIBC_2.4
  GLIBC_2.15
  GLIBC_2.18
  GLIBC_2.23
  GLIBC_2.24
  GLIBC_2.25
  GLIBC_2.26
  GLIBC_2.27
  GLIBC_PRIVATE
        
  # Current Version
  $ ldd --version
  ldd (Ubuntu GLIBC 2.27-3ubuntu1.6) 2.27

해당 저자의 경우 GLIBC_2.29 가 없고 2.27이기 때문에 해당 버전을 추가 설치 진행

[Step 2] 해당 버전 local에 설치

  $ wget -c https://ftp.gnu.org/gnu/glibc/glibc-2.29.tar.gz
  $ tar -zxvf glibc-2.29.tar.gz
  $ cd glibc-2.29
  $ mkdir build
  $ cd build
  $ ../configure --prefix=/usr/local/glibc-2.29/build --disable-sanity-checks
  $ make
  $ sudo make install

[Error] ** These critical programs are missing or too old: gawk bison

해당 library가 local에 설치가 되어 있지 않거나 version이 낮기 때문에 문제가 추가 발생

(1) gawk & bison 버전 찾기

  $ ls -lah /usr/bin/gawk
  ls: cannot access '/usr/bin/gawk': No such file or directory
  $ ls -lah /usr/bin/bison 
  ls: cannot access '/usr/bin/bison': No such file or directory
  $ bison --version
  $ gawk --version

(2) 해당 lib 설치

  $ sudo apt install gawk
  $ sudo apt install bison

[Step 3] 제대로 lib가 설치되었는지 확인

  $ cd /usr/local/glibc-2.29/build/lib
  $ ls | grep libm.so
        
  # Results
  libm.so
  libm.so.6

[Step 4] 해당 lib가 local GNU에 추가 및 soft linking (connection) 진행

  # Copy libm.so.6 in /usr/local/glibc-2.29/build/lib
  $ sudo cp /usr/local/glibc-2.29/build/lib/libm-2.29.so /lib/x86_64-linux-gnu/
        
  # Make a forced soft connection
  $ cd /lib/x86_64-linux-gnu/
  $ sudo ln -sf libm-2.29.so libm.so.6

[Step 5] 버전이 추가되었는지 최종 확인

  $ strings /lib/x86_64-linux-gnu/libm.so.6 | grep GLIBC_
        
  # Results
  GLIBC_2.2.5
  GLIBC_2.4
  GLIBC_2.15
  GLIBC_2.18
  GLIBC_2.23
  GLIBC_2.24
  GLIBC_2.25
  GLIBC_2.26
  GLIBC_2.27
  GLIBC_2.28
  GLIBC_2.29
  GLIBC_PRIVATE
