executable_prefer_symlink.mk revision cf331d931d4d254f1bccb18c27e675b41f764890 
1# include this makefile to create the LOCAL_MODULE symlink to the primary version binary.
2# but this requires the primary version name specified via LOCAL_MODULE_STEM_32 or LOCAL_MODULE_STEM_64,
3# and different with the LOCAL_MODULE value
4#
5# Note: now only limited to the binaries that will be installed under system/bin directory
6
7# Create link to the one used depending on the target
8# configuration. Note that we require the TARGET_IS_64_BIT
9# check because 32 bit targets may not define TARGET_PREFER_32_BIT_APPS
10# et al. since those variables make no sense in that context.
