# Bash script to assert that the current version of the NDK is at least the
|
|
# specified version. Prints 'true' to standard out if it's the right version,
|
|
# 'false' if it's not.
|
|
#
|
|
# Typically used like this, in your jni/Android.mk:
|
|
#
|
|
# ifneq ($(shell $(LOCAL_PATH)/assert_ndk_version.sh "r5c" "ndk-dir"), true)
|
|
# $(error NDK version r5c or greater required)
|
|
# endif
|
|
#
|
|
# See https://gist.github.com/2878774 for asserting SDK version.
