Hi Siyu, this, frankly, isn't the perfect mailing list for this topic. I've taken the discuss-gnuradio list into CC:; please sign up for that under [1] and continue discussing there!
I'll quickly address the things you say below: the ldconfig message is probably not a problem, just a misconfiguration of something on your system. You can ignore it. The -msse2 flag was added to GCC3.1 somewhen in May 2002. If you're building for x86 or x86_64 and your compiler doesn't know that, you either have a very strange compiler, or a *very* old one, that you simply can't use anymore. If you're not building for x86, you might want to tell us. Best regards, Marcus On 01.02.2017 16:08, zhan siyu via USRP-users wrote: > Hi all, > > Sorry for bother you.
