Hello Oscar, thank you for bugreport. The issue is due to the fact that crash-7.2.8 sources as retrieved from the new project WEB-site (github( are somewhat different from crash-7.2.8 as it was from old Dave Anderson's website. There is a new build process (Makefile etc.) for this 'new' version and as a result there are some problems. We plan to fix this shortly. Regards, Alex

Hi Rongwei, your solution is not very good as you will need to do this modification every time when you update PyKdump sources. You can achieve the same result like by using PYKDUMPPATH environment variable - it specifies all additional paths where to search for modules/programs. From epython.c sources: // We can specify extra path to search for modules and progs // by setting PYKDUMPPATH environment variable. // The order of search is like that: // 1. Current directory // 2. PYKDUMPPATH (if set,...

Hi Rongwei, by default, Python builds many modules as .so to be dynamically loaded. But to make PyKdump module as portable as possible, I link it against a specially built version of Python, with all needed modules built as 'static'. Look at https://sourceforge.net/p/pykdump/code/ci/master/tree/Extension/Setup.local-3.7 this is what I use for building Python. In particular, this compiles select module as 'static'. Regards, Alex

Hello, I work for HPE and some time ago I hoped that we'll get access to ARM64 but so far we have none. If you want to add support for it, it would be great. PyKdump used to work with IA-64 many years ago, but then Redhat stopped supporting it and I have removed it from PyKdump. There are three groups of changes to support new architectures: 1. Possible changes in C-module (related to integer sizes and endianness) 2. Python parts of framework, once again possibly related to integer sizes 3. There...

Hi Daniel, I was on vacation and just came back, sorry for delay with response. While we can discuss adding some specific modules, I think that adding all Python modules is not feasible, here is why. Python Standard Library includes both pure Python code and shared libraries that in turn might depend on other shared libraries. E.g. on my laptop: /usr/lib/python3.5/lib-dynload/ ls audioop.cpython-35m-x86_64-linux-gnu.so _bz2.cpython-35m-x86_64-linux-gnu.so cmath.cpython-35m-x86_64-linux-gnu.so _codecs_cn.cpython-35m-x86_64-linux-gnu.so...
