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.
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.
