[Mesa-dev] [PATCH 6/6] mesa: replace binary constants with hexadecimal constants

Andres Gomez agomez at igalia.com
Wed Aug 1 18:53:05 UTC 2018


The binary constant notation "0b" is a GCC extension. Instead, we use
hexadecimal notation to fix the MSVC 2013 build:

Compiling src\mesa\main\texcompress_astc.cpp ...
texcompress_astc.cpp
src\mesa\main\texcompress_astc.cpp(111) : error C2059: syntax error : 'bad suffix on number'

...

src\mesa\main\texcompress_astc.cpp(1007) : fatal error C1003: error count exceeds 100; stopping compilation
scons: *** [build\windows-x86-debug\mesa\main\texcompress_astc.obj] Error 2
scons: building terminated because of errors.

Fixes: 38ab39f6501 ("mesa: add ASTC 2D LDR decoder")
