Hi,
I'm having trouble compiling code that contains float128 data type.
I'm using MacOS Big Sur 11.4.
Compiler: gcc version 11.1.0 (Homebrew GCC 11.1.0_1)
I have no other problems with Boost, the only problem is when I use
float128.
Please note that I have no problem compiling using libquadmath without
using Boost using the __float128 data type.
I use Visual Studio Code:
You can manually fix this by defining BOOST_HAS_FLOAT128 on the command
line. However, you may still hit other errors as __float128 and
quadmath.h aren't really fully supported in ISO C++ mode. The correct
fix is to use -std=gnu++20, and then GNU extensions including __float128
are turned on.
HTH, John.
