添加编译包

添加quectel-CM app

OK3399-linux-source$ ls app/quectel-CM
build.sh        ethtool-copy.h  main.c     MPQCTL.h  MPQMUX.h            QMIThread.c  quectel-CM            quectel-qmi-proxy    udhcpc.c          util.h
default.script  GobiNetCM.c     Makefile   MPQMI.h   NOTICE              QMIThread.h  quectel-mbim-proxy    quectel-qmi-proxy.c  udhcpc_netlink.c
device.c        libmnl          mbim-cm.c  MPQMUX.c  qmap_bridge_mode.c  QmiWwanCM.c  quectel-mbim-proxy.c  ReleaseNote.txt      util.c

在buildroot中添加配置文件

添加编译依赖
diff --git a/buildroot/package/forlinx/Config.in b/buildroot/package/forlinx/Config.in

添加配置文件和编译文件

buildroot/package/forlinx/quectel-CM/Config.in
config BR2_PACKAGE_QUECTEL_CMbool "QUECTEL-CM"helpEC20 tool quectel-CM
buildroot/package/forlinx/quectel-CM/quectel-CM.mk
QUECTEL_CM_VERSION = 1.0
QUECTEL_CM_SITE = $(TOPDIR)/../app/quectel-CM
QUECTEL_CM_SITE_METHOD = localQUECTEL_CM_LICENSE = Apache V2.0
QUECTEL_CM_LICENSE_FILES = NOTICEdefine QUECTEL_CM_BUILD_CMDS$(TARGET_MAKE_ENV) $(MAKE) -C $(@D) CC=$(TARGET_CC)
endefdefine QUECTEL_CM_INSTALL_TARGET_CMDS$(INSTALL) -D -m 0755 $(@D)/quectel-CM  $(TARGET_DIR)/usr/bin/quectel-CM
endef$(eval $(generic-package))

需要注意的是配置文件中的config BR2_PACKAGE_QUECTEL_CM要和编译文件里的配置字段要匹配:

(*_QUECTEL_CM	对应	QUECTEL_CM_*)

在buildroot配置文件中添加app的编译选项

diff --git a/buildroot/configs/rockchip_rk3399_defconfig b/buildroot/configs/rockchip_rk3399_defconfig

编译后查看编译结果:

OK3399-linux-source$ find buildroot/ -name "quectel-CM"
buildroot/package/forlinx/quectel-CM

.stamp_built							表示该源码已经被编译过
.stamp_configured						表示该源码已经被配置过
.stamp_rsynced							目测表示该源码已经被同步
.stamp_target_installed					表示该源码编译结果已经被安装,安装目录一般是target目录

还有几个类似的文件

.stamp_downloaded						表示该源码已经被下载过,如果没有此文件会重新进行下载
.stamp_patched							表示此文件已经打过补丁
.stamp_extracted						表示此文件已经被压缩过,一般该目录下会有个压缩包

重新编译

修改了buildroot中的内容后需要重新编译,如果编译过的某个package目录下有上面的这几个文件,该包就不会进行重新编译。
如果需要重新编译这个package,可以删除这几个文件,或者某个文件,使得某几个编译步骤重新执行。

e.g.
rm buildroot/output/rockchip_rk3399/build/libnspr-4.17/.stamp_*

不过实际过程中可能会有编译不过的情况出现,这个时候可以从其他路径下面拷贝需要的.stamp文件,这样就可以编译通过了。

或者可以执行make clean命令,清除output路径下的全部内容,不过重新编译的耗时会很长。
