# Info:
|
|
# This makefile is gnu-make spacific, other make systems needn't understand it
|
|
# This makefile generates include-file dependencies into *.d files in each build and then reuses these dependencies in the following builds
|
|
#
|
|
# Usage:
|
|
# To make a release build, call "make release=1"
|
|
# To make a debug build, call "make"
|
|
# To make a 32-bit build on 64-bit OS, pass the addm32=1 flag
|
|
# To build with clang, you need to add disableasm=1 flag
|
