# error <cfloat> tried including <float.h> but didn't find libc++'s <float.h> header. \
|
|
This usually means that your header search paths are not configured properly. \
|
|
The header search paths should contain the C++ Standard Library headers before \
|
|
any C Standard Library, and you are probably using compiler flags that make that \
|
|
not be the case.
