cd source-code/readline-8.2/ ./configure --prefix=$bluez_output CC=$bluez_cc CXX=$bluez_cxx --host=$bluez_host CFLAGS="-fPIC" make -j8 && make install
CFLAGS=”-fPIC” : 为了后面方便连接静态库
ncurses交叉编译
cd source-code/ncurses-6.4/ ./configure --prefix=$bluez_output CC=$bluez_cc CXX=$bluez_cxx --host=$bluez_host --with-shared make -j8 && make install
–with-shared 默认生成静态库，加这个参数同时生成静态库和动态库
glib-2.46.2编译前准备
在正式编译glib之前需要提前编译依赖库
gettext交叉编译
解决：You must have either have gettext support in your C library, or use the GNU gettext library.
cd source-code/gettext-0.22.5/ ./configure --prefix=$bluez_output CC=$bluez_cc CXX=$bluez_cxx --host=$bluez_host CFLAGS="-fPIC" make -j8 && make install
编译libffi
解决： gclosure.c:28:10: fatal error: ffi.h: No such file or directory
cd source-code/libffi-3.4.5 ./configure --prefix=$bluez_output CC=$bluez_cc CXX=$bluez_cxx --host=$bluez_host CFLAGS="-fPIC" make -j8 && make install
编译zlib
解决：gzlibcompressor.c:26:10: fatal error: zlib.h: No such file or directory
cd source-code/zlib-1.3.1/ ./configure --prefix=$bluez_output
