I'm playing with these 2 tools on ubuntu 14.04.1 : simg2img make_ext4fs The first tool work great. But when I try to compile the image changed with the second tool I have in output this error: can't set android permissions - built without android support I have installed these two tools with the official package of ubuntu and also with the package of debian that seems more updated. Anyone can help me ? How I can compile these two tools ? Thank you, UPDATE I have write this script for compile this tool, but the error persist: sudo apt-get install git zlib1g-dev gcc make libpcre3-dev URL="https://android.googlesource.com/platform/system/core" git clone --depth 1 "$URL" "$(basename $URL)" URL="https://android.googlesource.com/platform/system/extras" git clone --depth 1 "$URL" "$(basename $URL)" URL="https://android.googlesource.com/platform/external/libselinux" git clone --depth 1 "$URL" "$(basename $URL)" git clone "extras" "extras-build" DIR=$(pwd) cd "extras-build/ext4_utils" gcc -Wall \ -o make_ext4fs \ -DHAVE_ANDROID_OS -DHOST \ -I$DIR/core/libsparse/include \ -I$DIR/libselinux/include \ make_ext4fs_main.c \ make_ext4fs.c \ ext4fixup.c \ ext4_utils.c \ allocate.c \ contents.c \ extent.c \ indirect.c \ uuid.c \ sha1.c \ wipe.c \ crc16.c \ ext4_sb.c \ $DIR/core/libsparse/backed_block.c \ $DIR/core/libsparse/output_file.c \ $DIR/core/libsparse/sparse.c \ $DIR/core/libsparse/sparse_crc32.c \ $DIR/core/libsparse/sparse_err.c \ $DIR/core/libsparse/sparse_read.c \ $DIR/libselinux/src/callbacks.c \ $DIR/libselinux/src/check_context.c \ $DIR/libselinux/src/freecon.c \ $DIR/libselinux/src/init.c \ $DIR/libselinux/src/label.c \ $DIR/libselinux/src/label_android_property.c \ $DIR/libselinux/src/label_file.c\ -lz \ -lpcre UPDATE 2: This is the final code: sudo apt-get install git zlib1g-dev gcc make libpcre3-dev URL="https://android.googlesource.com/platform/system/core" git clone --depth 1 "$URL" "$(basename $URL)" URL="https://android.googlesource.com/platform/system/extras" git clone --depth 1 "$URL" "$(basename $URL)" URL="https://android.googlesource.com/platform/external/libselinux" git clone --depth 1 "$URL" "$(basename $URL)" git clone "extras" "extras-build" cd "extras-build/ext4_utils" gcc -Wall \ -o make_ext4fs \ -I$DIR/core/include -DANDROID \ -DHAVE_ANDROID_OS -DHOST \ -I$DIR/core/libsparse/include \ -I$DIR/libselinux/include \ make_ext4fs_main.c \ make_ext4fs.c \ ext4fixup.c \ ext4_utils.c \ allocate.c \ contents.c \ extent.c \ indirect.c \ uuid.c \ sha1.c \ wipe.c \ crc16.c \ ext4_sb.c \ $DIR/core/libsparse/backed_block.c \ $DIR/core/libsparse/output_file.c \ $DIR/core/libsparse/sparse.c \ $DIR/core/libsparse/sparse_crc32.c \ $DIR/core/libsparse/sparse_err.c \ $DIR/core/libsparse/sparse_read.c \ $DIR/libselinux/src/callbacks.c \ $DIR/libselinux/src/check_context.c \ $DIR/libselinux/src/freecon.c \ $DIR/libselinux/src/init.c \ $DIR/libselinux/src/label.c \ $DIR/libselinux/src/label_android_property.c \ $DIR/libselinux/src/label_file.c\ -lz \ -lpcre Continue reading...
