libptmalloc currently works with any gdb version that supports Python >= 3.5.
libptmalloc code attempts to abstract the debugger so could theoretically be ported to any debugger with Python support.
Although libptmalloc may not require a glibc compiled with gdb debugging support and symbols, it functions best if you do use one. Without debug symbols you will need to supply the address of main_arena, mp_ and optionally tcache yourself.
apt-get install libc6-dbg
yum install yum-utils
debuginfo-install glibc
or
dnf install dnf-plugins-core
dnf debuginfo-install glibc
yum install glibc-debuginfo
On PhotonOS 1.0, the normal glibc library already includes symbols. On PhotonOS 3.0, you can get them from:
tdnf install glibc-debuginfo
Clone the repo:
git clone https://github.com/nccgroup/libptmalloc
Install the Python packages. Note that future-fstrings is only required for Python < 3.7 (so effectively for Python 3.5 and 3.6):
pip3 install -r libptmalloc/requirements.txt
Then install it globally:
sudo pip3 install ./libptmalloc/
or
cd libptmalloc
sudo python3 setup.py install
Then you can load it into gdb:
(gdb) python from libptmalloc import *
Note: you can add this command to your gdbinit:
echo "python from libptmalloc import *" >> ~/.gdbinit
If you don't want to install it globally, you can just source this file:
(gdb) source libptmalloc/pyptmalloc-dev.py
If you need to modify the libptmalloc and reload it in your debugger, please refer to DevelopmentGuide.md.
