build erlang with kqueue support
Tue Nov 16 09:47:10 CET 2021
I have an OpenBSD 6.8 amd64 machine and
I would like to compile Erlang 24 with kqueue support
such that I want erl to show me this:
I understand that this is a compile time option
and not anymore a runtime selectable option tru + K true
I tried the following configure options with no success:
--enable-threads --enable-kernel-poll --disable-hipe
With openbsd patches (+./otp_build update_configure)
and without patches the result is the same:
no kernel-poll flag present - meaning that kernel polling with kqueue
is not available to that erlang emulator.
Please advice me how to build erlang 24 with kqueue support.
I have an Openbsd 5.4 with erlang 19 that does has kernell-poll flag
$ erl +Ktrue
Erlang/OTP 19 [erts-8.1] [source] [64-bit] [smp:2:2]
Eshell V8.1 (abort with ^G)
building erlang 24 against openssl 1.1.1 for tlsv3 support wasn't
a pleasant experience. The configuration script links against
system libressl openssl library, instead of --with-ssl option given
So I had to alter manually crypto ./configure and Makefile files .
