That's not a boost problem, it's a gcc problem. You have to use at least gcc 8 for v3.9.3.0. Ron On 10/4/21 4:54 AM, Wojciech Kazubski via GNU Radio, the Free & Open-Source Toolkit for Software Radio wrote: GNU Radio has released v3.8.4.0 and v3.9.3.0, hitting the September target date with h

We only require C++14 but the compilers we test with support some C++17 features, e.g., filesystem. You are right that this change was made between 3.9.2.0 and 3.9.3.0. We should have put in an ifdef for backward compatibility here. If you change that line to boost/filesystem, does it work? That ap

Adding (hopefully not just noise) to this thread, I am curious as to whether my stopping flow graphs that contain a QT GUI time sink or frequency sink resulting in a segmentation fault is related to gr built with 8.2.1 while opensuse Leap 15.2 system libraries were built with GNU C++14 (SUSE Linux)

Note on compilers: a "may not work" warning is printed during cmake if the gcc version is < 8.3.0. So, 7.5.0 is not really supported, even though it may have worked in the past. On Mon, Oct 4, 2021 at 5:16 PM Aardric wrote: > Adding (hopefully not just noise) to this thread, I am curious as to >

The segfault also happens on Ubuntu 18.04 and gcc >= 8. It is exposed by these commits. https://github.com/gnuradio/gnuradio/commit/1e661918ad4fd096b2c990354c316602813246c7 https://github.com/gnuradio/gnuradio/commit/9f8ed5bb5decdcc6905e4a8cbd22ac31bca619a7 It appears to be related to the Qt v
