glibc-all-in-one

this repo helps you to download & debug & complie glibc easily.

feature

  • download glibc binary
  • download glibc debug file
  • extract custom glibc
  • download & complie glibc source code

usage

download

check supported packages. remember to run update_list at first.

➜  glibc-all-in-one ./update_list

download.

Note: use download for packages in the list; use download_old for packages in the old_list. If you need to debug a higher version of glibc with symbols,root privileges be required.

needed glibc not in my list ?

you can download the debs on your own, then use extract.

./extract ~/libc6_2.26-0ubuntu2_i386.deb /tmp/test
./extract ~/libc6-dbg_2.26-0ubuntu2_i386.deb /tmp/test_dbg

compile

supported version: 2.19, 2.23-2.29

supported arch: i686, amd64

note: you may fail to build older version of glibc. ( not my problem ) . my friend says that ubuntu 16.04 is perfect to build all of them.

note: change the GLIBC_DIR in the build, if you don't want to build them on /glibc.

./build 2.29 i686

Symbolic debugging of higher versions of glibc

If your environment is ubuntu16 or 18, then the default GDB version is lower (GDB < 8.3) and does not support parsing the symbol files in .build-id. In this case, you need to upgrade the GDB version.

Version 9.2 is recommended, use the following methods to complete the upgrade

apt install texinfo
cp `which gdb` `which gdb`-old
cp `which gdbserver` `which gdbserver`-old
wegt http://ftp.gnu.org/gnu/gdb/gdb-9.2.tar.gz
tar -xzvf  gdb-9.2.tar.gz 
cd gdb-9.2 && mkdir build && cd build
../configure --with-python=`which python3` --enable-targets=all
make && make install
