[sr-dev] IMPORTANT: Replacing old Makefiles with CMake

Hello, thanks to a significant effort/contribution done by Xenofon Karamanos, with some help from Alexandr Dubovikov during Kamailio Devel Meeting in Dusseldorf, support for using CMake (https://cmake.org/) for building Kamailio has been recently merged to git repository:   - https://lists.kamailio.org/mailman3/hyperkitty/list/sr-dev@lists.kamailio.o… The old build system based on manually crafted Makefiles got quite complex during the past 20 years, discovering and managing dependencies becoming harder and harder. Right now, both old Makefiles and the new CMake-based build system are available in order to help discovering what is missing in CMake files from what people use with the old Makefiles. However, the plan is to REMOVE the old Makefiles before freezing the development for v6.0.x (like 12 days or so). The testing phase for v6.0.x will be also used for tuning what is missing in the CMake files. Of course, it not going to end up to be 100% same set of build commands, but the goal is to have the commonly used ones. Besides that, CMake should facilitate easier automate testing and packaging. Therefore it is important that you upgrade your Kamailio build/packaging process to use CMake and report if there is something that you cannot achieve with it. Docs are available in the wiki at:   - https://www.kamailio.org/wikidocs/tutorials/cmake/default/   - https://www.kamailio.org/wikidocs/tutorials/cmake/custom/ You are encouraged to make pull requests to the above tutorials if you find something missing or useful to be known by the others. Another impact of the new CMake build system is to supported operating systems. CMake is widely available, however the developers have access to limited set of machines and they are also not very familiar with every OS out there. Old Makefiles (tried to) have support for very old OSes (from late 1990's early 2000's, like vax vms, sunos, ...), I haven't seen any activity related to them in the community for many years, therefore unless someone still uses such OS and contributes support for them, they will be lost by the cmake build system. Anyhow, in short, test on your favourite OS and report if something is not working.
