Illegal instruction 4
« on: January 10, 2013, 05:48:42 am »
Dear Xiang-Jun,

I registered and downloaded 3DNA v2.1beta (am working with Mac OS X Lion 10.7.5, BuildVersion:   11G63 on an iMac, 2.8 GHz Intel Core i7; I have xcode 4.5.1). I followed the instructions to set up the environment, etc (echo $X3DNA does return /Applications/x3dna-v2.1). When I however try find_pair -h to test the installation I get an error message:
Illegal instruction: 4

Does this mean I should install a Virtualbox and try the linux version, or can you recommend a different solution/fix?

Thanks in advance!
Susana

Hi Susana,

Thanks for reporting the "Illegal instruction" error message when you ran 3DNA on your Mac OS X Lion 10.7.5 machine. It was due to a backward compatibility issue for the 3DNA binaries I compiled on a newer 10.8.x (Mountain Lion) Mac. I've recompiled 3DNA on a Mac OS X 10.6 (Snow Leopard) and now it should work for you; please download the 3DNA 2013jan10 version from the download page and report back how it goes.

I am using a MacBook Air as the primary machine to develop 3DNA, so a native Mac OS X version of the software should always be available.

HTH,

Xiang-Jun
