Missing Homebrew OpenSSL path check on M1 Macs (2024)

The build script fails to check for SSL in /opt/homebrew/opt/openssl which seems to be the default location when installing OpenSSL via Homebrew on Apple Silicon (M1) Macs.

I ran into this issue when trying to build Fossil (version 2.15, 324154e821) on a new M1 Mac Mini (Big Sur, macOS 11.2).

Homebrew now installs to /opt/homebrew for macOS on Apple Silicon and continues to use /usr/local for macOS on Intel. See Homebrew install docs.

Initially running ./configure, yielded the following SSL checks:

Checking for system ssl...noChecking for ssl in /usr/sfw...noChecking for ssl in /usr/local/ssl...noChecking for ssl in /usr/lib/ssl...noChecking for ssl in /usr/ssl...noChecking for ssl in /usr/pkg...noChecking for ssl in /usr/local...noChecking for ssl in /usr...noChecking for ssl in /usr/local/opt/openssl...no

This solved the problem for me:

$ ./configure --with-openssl=/opt/homebrew/opt/openssl

I'm filing this as a bug because the Fossil SSL wiki mentions:

...we recomend that you use Homebrew on macOS to install OpenSSL as above. Fossil's build system will seek it out and use it automatically.

Thanks to everyone working on Fossil.

I expect that's a symlink to somewhere under /usr/local/Cellar, and that would be a better place to look for this.

The core problem here is that Apple hasn't shipped an up-to-date OpenSSL in years and years, probably part of this whole anti-GPL thing they've got going on, so we've got to go digging for third-party installs.

I've got an M1 coming, but it's somewhere between here and China at the moment. Maybe someone will beat me to a well-considered fix before it arrives.

Running brew install [email protected] ends up creating both

/opt/homebrew/opt/openssl

and

/opt/homebrew/opt/openssl/[email protected]

each is a symlink to

/opt/homebrew/Cellar/[email protected]/1.1.1i

In my original post, I suggested checking /opt/homebrew/opt/openssl since that seemed like the equivalent to the existing /usr/local/opt/openssl check (Homebrew Apple Silicon path vs. Homebrew Intel path).

BTW, on my old Intel Mac, /usr/local/opt/openssl is a symlink pointing to /usr/local/Cellar/[email protected]/1.1.1h.

Hope that helps.

Really? Because on my Big Sur system in which I just ran "brew upgrade openssl"to get OpenSSL 1.1.1i, it still puts the libraries in /usr/local/opt/openssl.

Nevertheless, I have added /opt/homebrew/opt/openssl to the list of directoriessearched. Please try again with the latest trunk check-in and report backwhether or not the problem has been cleared.

Can somebody else with a Mac run brew to install OpenSSL and report back whatdirectory it uses, to confirm bpk000's report?

Thank you. I can confirm that your check-in (Fossil 2.15, 17af40efff) works as expected. When running ./configure, Homebrew's OpenSSL install is found at /opt/homebrew/opt/openssl. Here's the relavent output:

Checking for system ssl...noChecking for ssl in /usr/sfw...noChecking for ssl in /usr/local/ssl...noChecking for ssl in /usr/lib/ssl...noChecking for ssl in /usr/ssl...noChecking for ssl in /usr/pkg...noChecking for ssl in /usr/local...noChecking for ssl in /usr...noChecking for ssl in /usr/local/opt/openssl...noChecking for ssl in /opt/homebrew/opt/openssl...okHTTPS support enabled

Like you, on my old Intel Mac, Homebrew has OpenSSL at /usr/local/opt/openssl which is a symlink to /usr/local/Cellar/[email protected]/1.1.1h. (I'm unsure how up-to-date that one is).

On my new M1 Mac, running brew install [email protected] ends up creating both

/opt/homebrew/opt/openssl

and

/opt/homebrew/opt/openssl/[email protected]

each is a symlink to

/opt/homebrew/Cellar/[email protected]/1.1.1i

For background, the M1 Mac was fresh from the factory. Fossil was my first attempted software build on the machine. That first time through was when I encountered the issue of no OpenSSL being found. After that, I installed Homebrew and subsequently used it to install OpenSSL (brew install [email protected]). Currently, that's the one and only package I've installed.

I found this Github issue for Homebrew's support of ARM/M1 where they mention a new prefix for macOS ARM:

Set and document the expected default prefix for macOS Intel Homebrew, macOS ARM Homebrew (/opt/homebrew) and Homebrew on Linux

If I can help in any way, please let me know. Again, many thanks.

If I can help in any way, please let me know.

Do the precompiled binaries for Mac run on your new M1?

Can you build a Fossil on your M1 and then make it available for usIntel users to try out?

I just built the most recent check-in (eb1a722f). You can access it from my Dropbox account. I included the output from configure and make in case that's helpful.

This may provide a direct download from Dropbox:

https://www.dropbox.com/s/oitn3g7gsafe7bi/Fossil-eb1a722f-build.zip?dl=1

I'll test the precompiled binaries and report back.

I downloaded and tested the preview of 2.15 and 2.14. Both seem to work fine with basic commands. Command summary included below. Please let me know if there is anything else I can do to help.

Note that I have installed Rosetta, but my Terminal is NOT opened using Rosetta as detailed in this article.

Calling the file command on my local build shows:

$ file Fossil-eb1a722f/fossilFossil-eb1a722f/fossil: Mach-O 64-bit executable arm64

The prebuilt binaries show:

$ file ./fossil-macosx-2.15-preview-20210205/fossil./fossil-macosx-2.15-preview-20210205/fossil: Mach-O 64-bit executable x86_64$ file ./fossil-macosx-2.14/fossil ./fossil-macosx-2.14/fossil: Mach-O 64-bit executable x86_64
