libsass 3.6.1 is available via pkg_add libsass, but I see that libsass 3.6 support (#2685) is not due until version 5.x (#2111).

[nschonni]

Sorry, OpenBSD isn't a platform we support

[saper]

Let me help you anyway - node-sass releases are tightly bound to some corresponding libsass version. I would advice against trying to build node-sass binding against pre-installed library from OpenBSD ports unless you are 100% sure you have the matching libsass version. (package.json file contains this information if there are no slip-ups like #2621). There are flags to do this if you like - just check my experimental FreeBSD port tree at https://github.com/saper/ports-exp/tree/master/textproc/node-sass

Your particular problem here is the compiler. What is the g++ version you are using right now?

[morgant]

@saper Thank you for your time! I was just exploring the g++ versions available on OpenBSD due to the errors and it appears that g++ 4.2.1 (so pre-C++11) is in base, though g++ 8.3.0 is available in ports as eg++.

I found your instructions on Clang Support on FreeBSD and tried a CXX=clang++ npm install. That seemed to work.

[qbit]

Hi,

On OpenBSD you need to use clang++ (CXX=/usr/bin/clang++):

$ env CXX=/usr/bin/clang++ npm install node-sass
$ node
> var s = require('node-sass');
undefined
> console.log(s.info)
node-sass       4.13.1  (Wrapper)       [JavaScript]

[morgant]

Thanks @qbit, I had just found that.

[saper]

Great - if someone from OpenBSD community would like to prepare a port and build binaries, we could add them to the official matrix - this way a proper binary will be downloaded automatically via npm without the need to compile anything.

Important: please use the same C++11 compiler that has been used to compile node itself to avoid runtime C++ ABI incompatibilities.

[ghost]

Yes - please add support someone. OpenBSD is years ahead of any other Unix-based platform, period.

Thanks @morgant and @qbit for your insights.

People don't forget to add this to your /etc/zprofile (Zsh):

export CC=/usr/bin/clang
export CXX=/usr/bin/clang++

[qbit]

@ratahtatah I would avoid setting them globally, doing so will force everything to use clang, not just npm.

A better alternative would be to make an npm alias, something like:

alias npm='env CXX=/usr/bin/clang++ npm'

That way only npm will be impacted.

[anon987654321]

This problem is back you guys: #2916

[saper]

@anon987654321 This is because we do not distribute OpenBSD binaries with the node-sass releases. See also #2885 (comment)

[anon987654321]

The fix is here: https://marc.info/?l=openbsd-ports&m=160657052927238

ln -s /usr/local/bin/node /tmp/node

Don't forget to replace gcc with clang:

export CC=/usr/bin/clang
export CXX=/usr/bin/clang++

Shoutout to Solene for the help.
