# PROBLEMS WITH SKIA DEBUGGING?? READ THIS...
|
|
#
|
|
# The debug build results in changes to the Skia headers. This means that those
|
|
# using libskia must also be built with the debug version of the Skia headers.
|
|
# There are a few scenarios where this comes into play:
|
|
#
|
|
# (1) You're building debug code that depends on libskia.
|
|
# (a) If libskia is built in release, then define SK_RELEASE when building
|
|
# your sources.
|
|
# (b) If libskia is built with debugging (see step 2), then no changes are
|
|
# needed since your sources and libskia have been built with SK_DEBUG.
|
|
# (2) You're building libskia in debug mode.
|
|
# (a) RECOMMENDED: You can build the entire system in debug mode. Do this by
|
|
# updating your build/core/config.mk to include -DSK_DEBUG on the line
|
|
# that defines COMMON_GLOBAL_CFLAGS
|
|
# (b) You can update all the users of libskia to define SK_DEBUG when they are
|
|
# building their sources.
|
|
#
|
|
# NOTE: If neither SK_DEBUG or SK_RELEASE are defined then Skia checks NDEBUG to
|
|
# determine which build type to use.
