I got compilation errors when I tried to build hyperscan library on my m/c user@ubuntu4:~/downloads/hyperscan-4.1.0/build$ uname -a Linux ubuntu4 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux Attached is the error log which gives the idea of what I did ... I googled it and got this https://github.com/Homebrew/legacy-homebrew/pull/49876 I tried similar thing on my linux by removing "march=native" from c_flags but it did not help. Please help. Thanks & regards, Vishal V. Kotalwar
