After installing lightworks I get the following error when trying to run it.

/usr/lib/lightworks/ntcardvt: error while loading shared libraries: libcrypto.so.1.0.0: cannot open shared object file: No such file or directory

There are multiple files in /usr/lib/lightworks that depend on openssl 1.0.0.

ldd /usr/lib/lightworks/libOSPrivate.so
libcrypto.so.1.0.0 => not found
libOS.so => not found
libmisc.so => not found
liblw.so => not found

ldd ntcardvt
libcrypto.so.1.0.0 => not found

There are a couple of apps in the repo that also use libcrypto.so.1.0.0 but they provide their own copy of it so it's not in /usr/lib.

Lightworks is supposed to be ready for openssl 1.1, I already tried to re-package to see why it still is looking for openssl 1.0. Checked upstream too, no indication they still require old openssl.
Since there is nothing to compile for Lightworks, not much I can do at this point, will keep checking where this issue is (KaOS only, or other distro's see this too).

2 months later

Lightworks 14.6.0 Beta fixes this issue, thus the beta version is now used for KaOS (now in the build repo, will move shortly to all users).
