Hello,

I have been trying to compile UxPlay but keep getting following error:

System is up to date:

DISTRIB_ID=Ubuntu DISTRIB_RELEASE=20.04 DISTRIB_CODENAME=focal DISTRIB_DESCRIPTION="Ubuntu 20.04.4 LTS"

What could be issue here?

Thanks

Compiled and works fine on Ubuntu 20.04.4 LTS on x86_64 5.13.0-27-generic #29~20.04.1-Ubuntu SMP Fri Jan 14 00:32:30 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

I dont understand why you are seeing references to libcrypto.a and zlib. (the static .a version of libcrypto is only used in macOS builds).

Something is messed up with your OpenSSL installation maybe. Is it a "standard " x86_64 system or something else like Raspberry Pi etc. Maybe your zlib is messed up ?? c_zlib.o ??

Start again from scratch, download a fresh copy of UxPlay, start with a clean build directory, go though the installation instructions and post the output you get when you run cmake (i.e. before make)

is g++ installed (sudo apt-get install g++)?

I see /usr/local/lib/libcrypto.a This tells me that you have a second installation of openSSL in /usr/local. Why?

it's confusing cmake. For macOS builds, openSSL gets installed there, because mac uses the libressll variant.

get rid of it and use the openssl and libssl-dev provided by Ubuntu 20.04

[fduncanh]

If having an "extra" OpenSSL in /usr/local is not a mistake

sudo apt-get install libssl-dev export OPENSSL_ROOT_DIR=/usr/lib/x86_64-linux-gnu/

before running cmake in the UxPlay build process. (this assumes your Ubuntu-20.04 system is an x86_64 system)

[uke75]

Got it compiled now with exporting correct ssl dir /usr/lib/x86_64-linux-gnu/

Yeah, it is Ubuntu-20.04 x86-64 system. Though, can't remember which app "/usr/local/lib/libcrypto.a" was installed with. System has been running from 2018, or so, and there has been installed/uninstalled (also manually) a lot of different software.

@uke75 its not from ubuntu. something else you installed "by jhand" put it there in /usr/local/....
