This code is invalid according to standard C++. It looks like support for non-POD VLAs was added as an extension to match GCC in Clang 3.9. ​https://github.com/llvm/llvm-project/commit/e7545b33ff79c55d08d78a35b052e494ea49a0bc

Resolution: → fixed
Status: assigned → closed

In 445aa33ee018fb8b1dc7e4789b7b2833e6b6568d/macports-ports (master):

SDRangel: fix build on macos <= 10.11

quick and dirty fix for
error: variable length array of non-POD element type 'complex<float>'

should be fine since it is a DSP library (DVB-S2 implementation) and
therefore not changed frequently; if something change, the patch fails
to apply.

Closes: #59537
