Automake 及交叉编译的使用

# vi Makefile.am
AUTOMAKE_OPTIONS = foreign
SUBDIRS = src

# vi src/Makefile.am
bin_PROGRAMS = platinum
platinum_SOURCES = platinum.c
platinum_LDADD = -lpthread

# autoscan
# mv configure.scan configure.in
# vi configure.in（添加 AM_INIT_AUTOMAKE）
# autoreconf -i

测试：
# ./configure --host=x86_64-pc-linux-gnu（使用交叉编译）
