Sdk: dotnet restore failing with "Unable to load DLL 'System.Security.Cryptography.Native'" on macosx

Expected behavior

I expected to get no error while restoring packages.

Actual behavior

Getting the error below while restoring packages:

Installed OpenSSL with macports:

  openssl @1.0.2g_0 (active)

Installing openssl using homebrew worked for me

[lukka]

I really hope that macports is not the issue here, as it should be supported :) I will investigate further

[lukka]

@karimelm installing with homebrew openssl (openssl-1.0.2g.el_capitan.bottle.tar.gz) did the trick, now i can got rid of the issue related to Unable to load DLL 'System.Security.Cryptography.Native' . I wonder why dotnet/cli rely on homebrew and not on macports.

[ckkashyap]

I continue to see the error even after installing openssl using brew - I must mention that, for me, brew installs everything in my home directory. Is there someway, I can provide LD_LIBRARY_PATH or something?

[ckkashyap]

Problem solved for me :) .. adding soft links from /usr/local/opt to my homebrew did the trick

[TheRealPiotrP]

The dependency comes from https://github.com/dotnet/CoreFx. If you have suggestions on how to eliminate it, that's the right place!

[sayedihashimi]

@piotrpMSFT I just ran into this with the latest. To get around it I installed openssl via homebrew as mentioned above. Since we closed this, is this a known requirement to work with .NET on a mac or is there another way to enable this besides installing openssl?

[sayedihashimi]

I see that openssl is listed at http://dotnet.github.io/getting-started/ as a prereq for the OSX case. Ignore my previous question.

[bartonjs]

For future finders, not interacting well with macports or user-scoped-brew-install is tracked now at https://github.com/dotnet/corefx/issues/8124.

Remember to run brew link --force openssl

[sleemer]

@nicc777 it doesn't work for me... When i run this command i get
brew link --force openssl
Warning: Refusing to link: openssl
Linking keg-only OpenSSL means you may end up linking against the insecure,
deprecated system version while using the headers from the Homebrew version.
Instead, pass the full include/library paths to your compiler e.g.:
-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib

[lokinfey]

@nicc777 I have the same problem as @sleemer

[themadbaron]

@nicc777 I have the same problem as @lokinfey and @sleemer.

[todika]

@nicc777 I have the same problem as @lokinfey, @sleemer and @themadbaron.

[nicc777]

@sleemer @lokinfey @themadbaron @dvtodika - have a look at http://stackoverflow.com/questions/38670295/brew-refusing-to-link-openssl - this may help.

[bartonjs]

The recent change to homebrew is something that we're trying to follow up on.

I had the same problem... this works ;)

Instead of the ln instructions found here: https://www.microsoft.com/net/core#macos, I had to do the following:

ln -s /usr/local/homebrew/Cellar/openssl/1.0.2j/lib/libssl.1.0.0.dylib /usr/local/lib/
ln -s /usr/local/homebrew/Cellar/openssl/1.0.2j/lib/libssl.1.0.0.dylib /usr/local/lib/

[bartonjs]

@samspot You'll want to find the path under opt, since that won't contain the patch version number and thus will get newer versions of the library when you upgrade:

bartonjs@jsb-mac:~/coreclr $ find -L `brew --prefix` -name libcrypto.1.0.0.dylib
/usr/local/Cellar/openssl/1.0.2g/lib/libcrypto.1.0.0.dylib
/usr/local/Cellar/openssl/1.0.2h_1/lib/libcrypto.1.0.0.dylib
/usr/local/Cellar/openssl/1.0.2i/lib/libcrypto.1.0.0.dylib
/usr/local/Cellar/openssl/1.0.2j/lib/libcrypto.1.0.0.dylib
/usr/local/lib/libcrypto.1.0.0.dylib
/usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib

In my case here, the last entry. (The /usr/local/lib one is obviously wrong, since that's the one that you're trying to make, and the rest have version numbers in them)

[samspot]

I'm not sure I understand. It looks like you are redirecting me back to the original linking instructions, which I could not get to work even after trying several workarounds.

My output:

$ find -L brew --prefix -name libcrypto.1.0.0.dylib
/usr/local/homebrew/Cellar/openssl/1.0.2j/lib/libcrypto.1.0.0.dylib
/usr/local/homebrew/lib/libcrypto.1.0.0.dylib
/usr/local/homebrew/opt/openssl/lib/libcrypto.1.0.0.dylib
/usr/local/homebrew/var/homebrew/linked/openssl/lib/libcrypto.1.0.0.dylib

[bartonjs]

@samspot Right, so you want

ln -s /usr/local/homebrew/opt/openssl/lib/libcrypto.1.0.0.dylib /usr/local/lib/
ln -s /usr/local/homebrew/opt/openssl/lib/libssl.1.0.0.dylib /usr/local/lib/

Though since you already have symlinks there you either need to remove them first or use ln -sf instead of ln -s. Your opt directory is under /usr/local/homebrew instead of /usr/local. (Presumably brew --prefix for you reports /usr/local/homebrew?)

[samspot]

ok great, thanks a lot!
