1、下载android的ndk与sdk。自己网上找下。我用的NDK为android-ndk-r15c
2、生成工具链$NDK/build/tools/make-standalone-toolchain.sh --arch=arm --platform=android-21--install-dir=/home/sukaarch、install-dir与platform根据实际选。$NDK为NDK的目录
3、下载xbmc并切换到avahi分支git clone https://github.com/theuni/xbmc.gitgit checkout remotes/origin/android-avahigit checkout -b android-avahicdxbmc/tools/android/depends
4、修改configure.in，找到zipalign，修成对应sdk的zipalign路径如：if [ ! test -f $use_sdk/build-tools/27.0.3/zipalign ]; then
5、修改Makefile.in的SUBDIRS ，只编译我们需要的：SUBDIRS = \ expatlibcap dbus libcap libdaemon avahi
6、修改Makefile.include.in ，修改gcc与g++export CC=$(CROSSTOOLS)clangexport CXX=$(CROSSTOOLS)clang++
7、autoconf版本换高的。修改autoconf/MakefileVERSION=2.69
8、automake版本换高的。修改automake/MakefileVERSION=1.15SOURCE=$(LIBNAME)-$(VERSION)ARCHIVE=$(SOURCE).tar.gzBASE_URL=https://ftp.gnu.org/gnu/automake/
9、修改avahi/glob.patch，加减反一下,如下+ sd-daemon.h sd-daemon.c glob.c \- sd-daemon.h sd-daemon.c \
10、修改avahi/0001-Add-Android-support.patch,注释掉in6_pktinfo+#if 0 //def __BIONIC__+struct in6_pktinfo {+ struct in6_addr ipi6_addr;+ int ipi6_ifindex;+};+#endif修改avahi/0001-Add-Android-support.patch,sys/_types.h改<sys/types.h>+#include <sys/types.h>修改avahi/0001-Add-Android-support.patch,注释掉size_t+#if 0//ndef _SIZE_T_DECLARED+typedef __size_t size_t;+#define _SIZE_T_DECLARED+#endif修改avahi/0001-Add-Android-support.patch,释放GLOB_ERR定义+#if 1//__POSIX_VISIBLE >= 199209+/* Believed to have been introduced in 1003.2-1992 */+#define GLOB_APPEND 0x0001 /* Append to output from previous call. */+#define GLOB_DOOFFS 0x0002 /* Use gl_offs. */修改avahi/0001-Add-Android-support.patch,释放GLOB_LIMIT定义+#if 1// __BSD_VISIBLE+#define GLOB_ALTDIRFUNC 0x0040 /* Use alternately specified directory funcs. */+#define GLOB_BRACE 0x0080 /* Expand braces ala csh. */修改avahi/0001-Add-Android-support.patch,将ARG_MAX替换为limit = sysconf(_SC_ARG_MAX);删除掉issetugid的调用issetugid() != 0 ||
11、修改avahi/Makefile，增加版本VERSION=0.6.32CONFIGURE增加--disable-glib \--disable-gobject \--enable-compat-libdns_sd \LIBS="-llog -lc" \CFLAGS="-pie -fPIE" \同时删除--disable-shared
12、修改dbus/Makefile，换高版本,如下include ../Makefile.includeDEPS= ../Makefile.include Makefile# lib name, versionLIBNAME=dbusVERSION=1.13.4SOURCE=$(LIBNAME)-$(VERSION)ARCHIVE=$(SOURCE).tar.gzBASE_URL=http://dbus.freedesktop.org/releases/dbus# configuration settingsCONFIGURE=cp -f $(CONFIG_SUB) $(CONFIG_GUESS) .; \ ./configure --prefix=$(PREFIX) --host=$(HOST) \ --without-x --disable-xml-docs --disable-doxygen-docs \ --with-dbus-user=root CFLAGS="-pie -fPIE" \LIBDYLIB=$(PLATFORM)/$(LIBNAME)/.libs/libdbus-1.aCLEAN_FILES=$(ARCHIVE) $(PLATFORM)all: .installed-$(PLATFORM)$(TARBALLS_LOCATION)/$(ARCHIVE): $(RETRIEVE_TOOL) $(RETRIEVE_TOOL_FLAGS) $(BASE_URL)/$(ARCHIVE)$(PLATFORM): $(TARBALLS_LOCATION)/$(ARCHIVE) $(DEPS) rm -rf $(PLATFORM)/*; mkdir -p $(PLATFORM) $(ARCHIVE_TOOL) $(ARCHIVE_TOOL_FLAGS) $(TARBALLS_LOCATION)/$(ARCHIVE) #cd $(PLATFORM); patch -p1 < ../android-upstream.patch #cd $(PLATFORM); patch -p1 < ../android.patch cd $(PLATFORM); $(CONFIGURE)$(LIBDYLIB): $(PLATFORM) sed -i "/^#define HAVE_POSIX_GETPWNAM_R/d" $(PLATFORM)/config.h $(MAKE) -C $(PLATFORM)/.installed-$(PLATFORM): $(LIBDYLIB) $(MAKE) -C $(PLATFORM)/ install cp $(PLATFORM)/dbus-1.pc $(PKG_CONFIG_PATH) touch $@clean: $(MAKE) -C $(PLATFORM) clean rm -f .installed-$(PLATFORM)distclean:: rm -rf $(PLATFORM) .installed-$(PLATFORM)
13、修改expat/Makefile，增加版本VERSION=2.2.5SOURCE=$(LIBNAME)-$(VERSION)ARCHIVE=$(SOURCE).tar.bz2BASE_URL=https://jaist.dl.sourceforge.net/project/expat/expat/2.2.5
14、生成configure 并执行./bootstrap./configure --prefix=/etc/android --host=arm-linux-androideabi \--with-ndk=/home/suka/android-ndk-r15c --with-sdk=/home/suka/android-sdk-linux \--with-sdk-platform=android-21 --with-tarballs=pack --with-toolchain=/home/suka/arm-linux-androideabi --with-staging=/etc/android \CC=/home/suka/arm-linux-androideabi/bin/clang CFLAGS="-pie -fPIE"其中，prefix与with-staging要和安卓的目录一致。with-sdk-platform为要用的sdk版本
15、创建libcap目录，里面增加Makefile，内容如下include ../Makefile.includeDEPS= ../Makefile.include# lib name, versionLIBNAME=libcapVERSION=2.25SOURCE=$(LIBNAME)-$(VERSION)ARCHIVE=$(SOURCE).tar.gzBASE_URL=https://mirrors.edge.kernel.org/pub/linux/libs/security/linux-privs/libcap2# configuration settingsCONFIGURE=cp -f $(CONFIG_SUB) $(CONFIG_GUESS) .; \ ./configure --prefix=$(PREFIX) --host=$(HOST) --without-cd-drive --without-cd-info --without-cd-paranoia \ --without-cdda-player --without-cd-read --without-iso-info --without-iso-read --disable-example-progs \ --disable-cpp-progs --without-cd-drive --without-cd-info --without-cd-paranoia --without-cdda-player \ --without-cd-read --without-iso-info --without-iso-read --disable-sharedLIBDYLIB=$(PLATFORM)/lib/driver/.libs/$(LIBNAME).aCLEAN_FILES=$(ARCHIVE) $(PLATFORM)all: .installed-$(PLATFORM)$(TARBALLS_LOCATION)/$(ARCHIVE): $(RETRIEVE_TOOL) $(RETRIEVE_TOOL_FLAGS) $(BASE_URL)/$(ARCHIVE)$(PLATFORM): $(TARBALLS_LOCATION)/$(ARCHIVE) $(DEPS) rm -rf $(PLATFORM)/*; mkdir -p $(PLATFORM) $(ARCHIVE_TOOL) $(ARCHIVE_TOOL_FLAGS) $(TARBALLS_LOCATION)/$(ARCHIVE) sed -i "s/-\/sbin\/ldconfig//" $(PLATFORM)/libcap/Makefile $(LIBDYLIB): $(PLATFORM) $(MAKE) -C $(PLATFORM)/libcap lib=lib prefix=$(PREFIX) CC=$(CC).installed-$(PLATFORM): $(LIBDYLIB) $(MAKE) -C $(PLATFORM)/libcap install lib=lib prefix=$(PREFIX) CC=$(CC) touch $@clean: $(MAKE) -C $(PLATFORM)/libcap clean rm -f .installed-$(PLATFORM)进入libcap，执行make.如出现下面错误./_makenames: 1: ./_makenames: Syntax error: word unexpected (expecting ")")修改armeabi-v7a/libcap/Makefile把_makenames: _makenames.c cap_names.list.h $(BUILD_CC) $(BUILD_CFLAGS) $< -o $@改成_makenames: _makenames.c cap_names.list.h gcc $(BUILD_CFLAGS) $< -o $@
16、退到depends执行makemake
17、生成的/etc/android/armeabi-v7a，都上传到系统中。在安卓上，运行mkdir -p /etc/android/armeabi-v7a/var/run/dbusdbus-daemon --system &avahi-daemon --no-chroot &
