1 Overview
目录结构:
comcat@jackslab:~/buildroot-2020.11.2$ ls arch board boot CHANGES Config.in Config.in.legacy configs COPYING DEVELOPERS dl docs fs linux Makefile Makefile.legacy output package README support system toolchain utils
2 添加包
comcat@jackslab:~/buildroot-2020.11.2$ mkdir -p package/helloworld/
在该目录下新建 Config.in:
config BR2_PACKAGE_HELLOWORLD bool "helloworld" help hello world package
新建 helloworld.mk:
comcat@lab:~/buildroot-2020.11.2$ cat package/helloworld/helloworld.mk HELLOWORLD_VERSION = 1.0.0 HELLOWORLD_SITE = $(TOPDIR)/../helloworld_src HELLOWORLD_SITE_METHOD = local define HELLOWORLD_BUILD_CMDS $(MAKE) $(TARGET_CONFIGURE_OPTS) -C $(@D) endef define HELLOWORLD_INSTALL_TARGET_CMDS $(INSTALL) -D -m 0755 $(@D)/helloworld $(TARGET_DIR)/usr/bin/helloworld #$(INSTALL) -D -m 0755 $(@D)/rx $(TARGET_DIR)/usr/bin/rx endef $(eval $(generic-package))
3 准备代码
$ mkdir ~/helloworld_src
放入 helloworld.c Makefile:
helloworld.c:
#include <stdio.h> #include <unistd.h> int main(int argc, int *argv[]) { while(1) { printf("Hello world\n"); sleep(1); } return 0; }
Makefile:
OBJS=helloworld.o all: helloworld helloworld: $(OBJS) $(CC) $(LDFLAGS) -o helloworld $(OBJS) $(OBJS): %.o: %.c $(CC) $(CFLAGS) -c -o $@ $<
