But for release build we should have LXC_DEVEL=0. LXC_DEVEL is a variable that appears in the /usr/include/lxc/version.h and then can be (and actually it is) used by other projects to detect if liblxc-dev is a development build or stable. Having LXC_DEVEL=1 makes problems for the users who want to build projects those are depend on liblxc from source (for example, LXD, go-lxc: https://github.com/canonical/lxd/pull/12420). Q: Why it was not a problem for so long? A: Because LXC API was stable for a long time, but recently we have extended liblxc API (https://github.com/lxc/lxc/pull/4260) and dependant package go-lxc was updated too (https://github.com/lxc/go-lxc/pull/166). This change was developed properly to be backward compatible with the old versions of liblxc. But, there is a problem. If LXC_DEVEL=1 then the macro check VERSION_AT_LEAST (https://github.com/lxc/go-lxc/blob/ccae595aa49e779f7ecc9250329967aa546acd31/lxc-binding.h#L7) is disabled. That's why we should *not* have LXC_DEVEL=1 for *any* release build of LXC. [ Test Plan ] Install liblxc-dev package and check /usr/include/lxc/version.h file LXC_DEVEL should be 0 [ Where problems could occur ] Theoretically, build of a software which depends on liblxc-dev may start to fail if it assumes that LXC_DEVEL is 1.
