gr-osmosdr and the compile flag -std=gnu++11

Hi - I presume since I'm receiving a number of these types of errors while compiling /opt/gnuradio/src/gr-oot/gr-osmosdr/lib/rtl_tcp/rtl_tcp_source_c.cc:307:7: warning: extended initializer lists only available with -std=c++11 or -std=gnu++11 cmd = { 0x0a, htonl(offset_tune) }; i.e., complaining about -std=gnu++11, that I should probably be compiling gr-osmosdr with the -std=gnu++11 flag. Typically, I fall asleep at the wheel during the build - so I don't know which version these warning started. If it wasn't for my dog's wet nose pressing against my elbow, I'd still be sleeping. I'm using the following git pulls for rtl-sdr: commit 18bf26989c926a5db4fca29e7d859af42af1437c Author: hayati ayguen <h_ayguen(a)web.de> Date: Sun Jun 11 00:18:53 2017 +0200 gr-osmosdr: commit c653754dde5e2cf682965e939cc016fbddbd45e4 Merge: b7aab45 cf95494 Author: Dimitri Stolnikov <horiz0n(a)gmx.net> Date: Mon Jun 12 00:04:36 2017 +0200 and I have somewhat recent git pulls for libosmocore and libosmo-dsp. Should I be compiling the programs rtl-sdr and gr-osmosdr with -std=gnu++11? How about libosmocore and libosmo-dsp? -- Cinaed
