Re: [dpdk-users] Gcc 6.4 failure compile

Aw you got it sse4_1 sse4_2

flags		: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss ht syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon rep_good nopl eagerfpu pni pclmulqdq vmx ssse3 fma cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand hypervisor lahf_lm abm tpr_shadow vnmi flexpriority ept fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid xsaveopt

It is not for the machine on which  I'm working the binary, how can I make the gcc  to ignore the host cpu flags ?

Can you show the results of Flags of your machine? Use "lscpu" or "cat /proc/cpuinfo".
Are there sse4_1 and sse4_2?
