crystal doesn't work with OpenSSL 1.1.0f (Debian 9)

[mixflame]

Just booted up a new 64-bit 4gb Debian 9 Linux to show off my Crystal app.

Still no-go... Nothing will compile because Crystal's OpenSSL support doesn't work with the version on Debian 9.

Still not sure what to do. Thanks :beers:

There is a conflict. Crystal determines 1.0.x is present, but it eventually gets linked against 1.1.0, which obviously fails. What does pkg-config libssl --mod-version reports?

[mixflame]

livepost@livepost:~/amber_cmd$ pkg-config libssl --modversion
1.1.0f

[mixflame]

this is an issue on latest Kali Linux too

[Wulfklaue]

This issue is indeed still present in:

Linux Node1 4.9.0-3-686-pae #1 SMP Debian 4.9.30-2+deb9u5 (2017-09-19) i686 GNU/Linux

Crystal 0.23.1 [e2a1389] (2017-07-13) LLVM 3.8.1

Exact same description as the OP.

I was having the same issue on WSL (aka Bash on Ubuntu on Windows) which runs Ubuntu 16.04 xenial. I've solved my problem by removing and reinstalling libssl1.1 package. Careful, removing libssl1.1 will break lots of other packages including libssl-dev, openssl etc., take a look at apt output before proceeding and reinstall other packages too.

I have the same problem with Crystal 0.24.1 on Debian Buster.

[RX14]

This is weird: it works on archlinux with the same pkg-config libssl --modversion as 1.1.0g.

[RX14]

What's the result of pkg-config --atleast-version=1.1.0 libssl; echo $? on debian systems where this fails?

[007lva]

I get 1, BTW apt install libssl1.0-dev fix the issue to me.

[MrSorcus]

Same issue on Archlinux

@MrSorcus i'm on latest archlinux and it works just fine for me. You clearly have the latest crystal package (2018-09-17) so i'm not sure what's happening.

What's pkg-config libssl --modversion for you?

[MrSorcus]

@RX14

[root@localhost]# pkg-config libssl --modversion
1.1.1

Hmm... After installing pkgconf code can be compiled. My fault?

[RX14]

@MrSorcus might want to make an arch bug to make crystal to depend on pkgconf.

But then again crystal doesn't depend on a C compiler either so maybe base-devel is an implied dependency.

[rafaelfesi]

@RX14

[root@localhost]# pkg-config libssl --modversion
1.1.1

Hmm... After installing pkgconf code can be compiled. My fault?

Same here using:

• Debian 10 (Buster) on WSL 2
• Crystal version 0.33.0.

Also solved after installing pkgconf.

❯ pkg-config libssl --modversion
1.1.1d

If I uninstall pkgconf, it stops working:

❯ sudo apt remove pkg-config

As we can see, the command fails because pkg-config was not installed by default and is needed.

[RX14]

@rafaelfesi the crystal APT package already depends on pkg-config...
