Excellent. This will run slower on more modern systems, so I think I'll
just create two different binaries again - one that requires 10.7 and doesn't
require AVX, and one that runs on 10.9 and newer and utilizes AVX.

I identified the four libraries that had AVX instructions included and manually
rebuilt them with that disabled (which took a few attempt for openssl).

Robert, I know it's getting late, but could you possibly try

I think HomeBrew by default builds targetting the local machine (-
march=native), which makes the binaries unsuitable for distribution. There's a 
switch somewhere to make it build generic binaries.

And this library comes from OpenSSL which we get from HomeBrew. I can already
see that I will hate where all this will take me, but I appreciate that thanks 
to Robert's
access (if somewhat limited) to such an old machine we got reminded of the 
issue...

Doing some more research, it seems that not a lot of Macs should fall into the 
narrow
overlap of "able to run 10.7 and don't have AVX". But I'll see what I can do.

IIRC, 4.5.6 should fail on that hardware as well. Would you mind testing that, 
first?

this machine is very very slow and my access to it is through VNC only (with 
the alternative turning on the projector and holding a white piece of paper in 
the air).

I can go and try to install Xcode but this might take forever.

Any chance you can get the backtrace or disassembly of the crashing 
instruction? This rings a bell of a problem we had way in the past when some 
code had AVX instructions, which would cause it to run on hardware pre-2011.

I have a 10.9 VM in the office, so I can test it in a week's time.

Unfortunately, it didn't occur to me to create VMs from the recovery images 
until after I had upgraded from 10.8 to 10.9, so I can't test 10.8.

Dirk,

I tried this on my old old MacMini (that I use as TV replacement). The hardware 
is so old that it is stuck on 10.7.

It opens up the main window but then shows the spinning beach ball and then 
unfortunately crashes.

On the bottom I add the crash report (seems somewhere in lib crypto is a 
problem).

From the command line it's the same, it crashes with "Illegal instruction:4"

Thread 5:: Qt 

anyone with a Mac running 10.7 or 10.8?

[Dirk Hohndel]

From looking through the Subsurface cloud server logs I can see that we still 
have a 
fair number of users on MacOS 10.7 and 10.8. I went through the effort to 
create a 
DMG that should run even on 10.7. I'd love it if someone could verify that this 
actually 
works.

http://subsurface-divelog.org/downloads/daily/Subsurface-4.5.96-36-ge94d49668ef9-10.7.dmg

The regular DMG should run on 10.9 and newer (it would also be useful to verify 
that
this does, indeed, run on 10.9 and doesn't run on 10.7 or 10.8).

Thanks
