Cannot locate native library 'libssl.so'

[shalomb]

I'm not sure if this is a problem with NativeCall or OpenSSL but I get the following error when trying out the examples in the README.

Cannot locate native library 'libssl.so': libssl.so: cannot open shared object file: No such file or directory         

But as far as I can see, I do have libssl.so provided by libssl-dev on debian. What would cause this then?

@shalomb Can you try installing libssl1.0-dev and see if it fixes your issue? That resolved it for me.

[awgrover]

Same error. Should raku be more tolerant of versions of the library?

Installing: OpenSSL:ver<0.1.23>:authgithub:sergot
Cannot locate native library 'libssl.so': libssl.so: cannot open shared object file: No such file or directory

Ubuntu 18.04

packages installed: libssl1.0.0, libssl1.1

ldconfig -p | grep libssl.so

libssl.so.1.0.0 (libc6,x86-64) => /lib/x86_64-linux-gnu/libssl.so.1.0.0

I note the difference in file name ".so" vs ".so.1.0.0".

This work around fixes it:
ln -s /lib/x86_64-linux-gnu/libssl.so.1.0.0 /lib/x86_64-linux-gnu/libssl.so

[niner]

No, raku shouldn't be more tolerant. Native library's versions are just not optional but have to be specified like I did in niner@407ceac

[Skarsnik]

This is still an (annoying) issue. Having to install the -dev package of openssl is really bad x)

[sergot]

Hi @Skarsnik , as far as I remember I always had to install the libssl-dev for ssl related packages, for example in Python: https://www.pyopenssl.org/en/stable/install.html#supported-openssl-versions .

I am not sure how we can approach this issue to make it more user friendly, I'm open for ideas, thanks in advance!

❤️

[niner]

@sergot the solution is simple and already implemented in: #76

That PR is the correct solution and fixes this issue. It's just a bit outdated, but all the required pieces (e.g. in zef) are now in place.
