Installing B2G from an Add-On
Use BUILD_HOST_64bit=1 and/or BUILD_HOST_static=1 when building Android to get
either Linux 64 bits binaries or statically linked binaries. You can combine
both:
$ ls -l linux/* linux64/*
-rwxrwxr-x 1 alex alex 1437885 mai 25 12:09 linux64/make_ext4fs
-rwxrwxr-x 1 alex alex 784426 mai 25 12:10 linux64/mkbootfs
-rwxrwxr-x 1 alex alex 784346 mai 25 12:10 linux64/mkbootimg
-rwxrwxr-x 1 alex alex 1437885 mai 25 12:12 linux/make_ext4fs
-rwxrwxr-x 1 alex alex 784426 mai 25 12:12 linux/mkbootfs
-rwxrwxr-x 1 alex alex 784346 mai 25 12:12 linux/mkbootimg
Then to save some space, you can strip and pack binaries.
Stripping:
$ strip linux/* linux64/* && ls -l linux/* linux64/*
-rwxrwxr-x 1 alex alex 844344 mai 25 12:13 linux64/make_ext4fs
-rwxrwxr-x 1 alex alex 595528 mai 25 12:13 linux64/mkbootfs
-rwxrwxr-x 1 alex alex 591024 mai 25 12:13 linux64/mkbootimg
-rwxrwxr-x 1 alex alex 844344 mai 25 12:13 linux/make_ext4fs
-rwxrwxr-x 1 alex alex 595528 mai 25 12:13 linux/mkbootfs
-rwxrwxr-x 1 alex alex 591024 mai 25 12:13 linux/mkbootimg
Packing:
$ upx linux/* linux64/* && ls -l linux/* linux64/*
