Does not compile on OpenBSD

[worr]

Probably caused by the lack of spawn.h in OpenBSD

I also have this issue, but finally get it working. from posix_spawn.h then run patch -N < posix_spawn.diff i got this spawn.h copy this file to $rvm_path/usr/include

Would love to verify posix-spawn is currently compiling + working on OpenBSD so leaving this old issue open for a bit. If you have recent experience w/ OpenBSD please leave a note here.

Hi,

I've successfully installed posix-spawn on OpenBSD 5.6 amd64, running in a Vagrant/VMware Fusion VM (base box: fnichol/openbsd-5.6-amd64), without fiddling with anything. Details follow:

# uname -a 
OpenBSD puffy.localdomain 5.6 GENERIC.MP#333 amd64

Tested with the following rubies:

ftp://ftp.openbsd.org//pub/OpenBSD/5.6/packages/amd64/ruby-1.9.3.545p0.tgz ftp://ftp.openbsd.org//pub/OpenBSD/5.6/packages/amd64/ruby-2.0.0.481.tgz ftp://ftp.openbsd.org//pub/OpenBSD/5.6/packages/amd64/ruby-2.1.2.tgz

(IOW, I haven't tried with ports- the VM doesn't have ports installed- so they're all older versions).

For both 1.9.3 and 2.1, I get this output:

Fetching: posix-spawn-0.3.11.gem (100%)

For 2.0, I get this:

# gem20 install posix-spawn

Playing around in IRB, posix-spawn seems to be working just fine.

HTH :-)

Works for me. Thanks so much @dsp-eoss!

According to https://github.com/tmm1/pygments.rb/issues/45 and my experience, it doesn't work in OpenBSD 5.6 but it works in 5.7.
