OpenSSL & MacOS Build Process

[dahadaller]

Are there any plans to update the install instructions for macos Mojave? I recently updated, but now, when I tried to re-compile libscapi with the install instructions listed here, the brew link openssl step returns the following error:

Warning: Refusing to link macOS-provided software: openssl
If you need to have openssl first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

For compilers to find openssl you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl/include"

For pkg-config to find openssl you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig"

I have put each of those export statements in my .bash_profile and I've made sure that /usr/local/opt/openssl/bin comes before all other directories in the PATH.

I've also tried linking manually (according to this stackoverflow page), to no avail:

brew update    
brew install openssl    
ln -s /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib /usr/local/lib/    
ln -s /usr/local/opt/openssl/lib/libssl.1.0.0.dylib /usr/local/lib/

From what glean off forums, it might be that macos Mojave has it's own ssl library and that brew doesn't have the credentials to make openssl a default (even with the brew link --force option.) If I try to compile libscapi without first linking openssl, the compilation will progress for a while, and then it will terminate with the following error:

How could I remedy this? Any help at all would be much appreciated.

Same problem here.

Hello,

Which compiler you are using?

[liorko87]

I noticed right now that you are using the latest Macos version. Currently we are supporting only High Sierra 10.13.

I have also replicated this same problem in a colleague's (Bon, who is also on this thread) computer on High Sierra 10.13, too. My computer has Mojave. The compiler used on High Sierra computer was clang.
