<p>I'm trying to install cardano-node version 1.35.0 on my M1 Mac.  It worked (somewhat) previously with version 1.34.2 using LLVM.  Currently I am running into this error when it tries to build threepenny-gui:</p>
<pre><code>dlopen(/Users/stefan/.cabal/store/ghc-8.10.7/lib/libHSHsOpnSSL-0.11.7.2-e201b3b3-ghc8.10.7.dylib, 0x0005): symbol not found in flat namespace (_DSA_free)
</code></pre>
<p>It looks like the issue is with the openSSL library with cabal is missing a required symbol.  Does anyone have any suggestions on how to make this available?</p>

# Cardano-Node 1.35.0 Build Error on M1 Mac

(Asked by: username_0 on 2022-08-09)

I'm trying to install cardano-node version 1.35.0 on my M1 Mac.  It worked (somewhat) previously with version 1.34.2 using LLVM.  Currently I am running into this error when it tries to build threepenny-gui:
dlopen(/Users/stefan/.cabal/store/ghc-8.10.7/lib/libHSHsOpnSSL-0.11.7.2-e201b3b3-ghc8.10.7.dylib, 0x0005): symbol not found in flat namespace (_DSA_free)

It looks like the issue is with the openSSL library with cabal is missing a required symbol.  Does anyone have any suggestions on how to make this available?

The issue had to do with the openSSL library I was using and was resolved in the instructions provided here: <https://github.com/mallapurbharat/cardano-tx-sample/blob/main/0_installation/Old/macos_m1_process.md>

This included including the homebrew openssl library. Specifically [here](https://github.com/mallapurbharat/cardano-tx-sample/blob/main/0_installation/Old/macos_m1_process.md#edit-bashrc--zshrc-and-input-the-below-lines) and [here](https://github.com/mallapurbharat/cardano-tx-sample/blob/main/0_installation/Old/macos_m1_process.md#in-case-you-face-any-issues--errors-regarding-hsopenssl-add-the-below-lines-to-the-cabalproject-file-under-cardano-node-folder).
