libptmalloc currently works with any gdb version that supports Python >= 3.5. Note that if you use the dev branch, you'll need Python >= 3.7, see DevelopmentGuide.md for more information.

glibc/ptmalloc versions

The goal of libptmalloc is to support all ptmalloc and glibc versions.

That being said, it has only been tested extensively on a limited number of versions. If you encounter an error when using it, please create an issue or do a pull request.

We have used it extensively on the following versions:

Linux distribution	Binary/libc architecture	glibc version	Package	tcache
Centos 7 x64	x64	2.17	glibc-2.17-322.el7_9	No
Photon 1.0 x64	x64	2.22	glibc-2.22-26.ph1	No
Ubuntu 18.04 x64	x86	2.27	libc6-i386-2.27-3ubuntu1.4	Yes
Ubuntu 18.04 x64	x64	2.27	libc6-2.27-3ubuntu1.4	Yes
Photon 3.0 x64	x64	2.28	glibc-2.28-13.ph3	No (disabled)

The above list will be updated once we test more versions. Feel free to report any additional working version so we add it to the list.
