# Assembler error "File too big" caused by lots of C++ templates, for example, math/floating_point_examples.cpp.
# Some projects on some toolsets may require
# <toolset>gcc-mingw:<cxxflags>\"-Wa,-mbig-obj\"
# See https://digitalkarabela.com/mingw-w64-how-to-fix-file-too-big-too-many-sections/
# <toolset>gcc-mingw:<cxxflags>-Wa,-mbig-obj # Some projects may overflow assembler and require equivalent of MSVC /bigobj.
# Requires version 2.30 of GNU binutils.
# Best applied only to projects that require this, see run math/floating_point_examples.cpp below.
