And just in case - the topic was started due to my exersises with kqueue and if it is interesting for anybody, see [EDSM](http://zed.karelia.ru/0/e/) EDSM stands for 'event driven state machines' NOTE: despite the topic, those programs (echo client/server pair) work perfectly, but this is not suprisingly, because: * I am not using ext field in struct kevent_t * most likely I never get more than one event from kqueue() * buffer is 8 events long, so I always have extra space for that ext field.

On Wednesday, 22 December 2021 at 09:49:59 UTC, eugene wrote: It looks strange - leading D compiler is not in Linux/FreeBSD repos :) Well no so much. The only official compiler is DMD and when it comes to that, Digital Mars, has pre-built binaries for most Linux distros and for FreeBSD. Now the repos are another thing like I told you in a previous reply. The repos are managed by the distro maintainers and not the developers individual. D is a very unpopular language so it makes sense that not every distro (and freeBSD) have up to date packages. Some distros are not rolling release in general. FreeBSD (if I'm not mistaken) never promoted themselves as bleeding edge either. However, both DMD and LDC2 developers have up to date binaries for every platform they support. GDC is part of GCC so it's another story Also I prefer to use my distro's repos too for everything (and I can do that because I use Arch btw) but this is not possible every time. Downloading and installing binaries from other sites should be do some times, especially if you use non-bleeding edge distros or *BSD.

Forget about LDC :) I used outdated version of LDC (the one installed with pkg), which does not have struct kevent_t for 12+ at all. I was wrong: LDC is using its own code to determine the OS version, and it should already do that correctly. And I am **not** going to install up to date version of LDC, because I prefer to use packages supplied by repository maintainers (usually) FreeBSD has ldc2 (old, but it **is** in the repo) Linux has both gdc (also old) and ldc. It looks strange - leading D compiler is not in Linux/FreeBSD repos :)

I agree tho what I was wondering was if the latest version LDC2 will now have the missing definitions for freeBSD. The versioning will of course be wrong (as LDC2 uses DMD as a frontend from what I know) but if the other info isn't added then maybe we should add an issue in their Github.
