Platform:

Linux version 2.6.32-279.el6.x86_64

Cross compiler path:/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-

Development Board: FL2440

Board Runtime kernel: linux3.0

Development Board File system: JFFS2

First, the preparatory work

1. Create the FL-EASYCWMP directory to store the installation files

[Email protected] ~]$ mkdir FL-EASYCWMP

2. Create the Install directory

[Email protected] ~]$ CD fl-easycwmp/
[[email protected] fl-easycwmp]$ ls
[[email protected] fl-easycwmp]$ mkdir Install
[[email protected] fl-easycwmp]$ ls
Install

Second, cross-compiling json-c

1. Get json-c source files

[[email protected] fl-easycwmp]$ git clone git://github.com/json-c/json-c.git./json-c

2. Create build.sh

[Email protected] json-c]$ vim build.sh

#!/bin/bash
Prj_path= ' pwd '
#CROSS =/opt/buildroot-2011.11/arm920t/usr/bin/arm-linux-
cross=/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-
Make clean
#autoreconf-I.
Export CC=${CROSS}GCC
Export Cpp=${cross}cpp
Export As=${cross}as
Export LD=${CROSS}LD
Export Ar=${cross}ar
Export Ranlib=${cross}ranlib
Export Strip=${cross}strip
Export Ac_cv_func_malloc_0_nonnull=yes
Export Ac_cv_func_realloc_0_nonnull=yes
Export Ac_cv_have_decl_isinf=yes
Export Ac_cv_have_decl_isnan=yes
#export Ldflags + =-lm
./configure--enable-rdrand--disable-dependency-tracking--with-package--with-gnu-ld--with-pic--bu
Ild=i686-pc-linux-gnu--host=arm-linux--prefix=${prj_path}/. /install

By the way, Cflags's-wall-o2-g in makefile.

-wall is open warning switch,-O stands for default optimizations, optional:-O 0 is not optimized,-o1 low-level optimizations,-O2 intermediate optimizations,-O3 advanced optimizations,-os code space optimization.
-G is the generation of debug information, and the resulting executable file has the debug information associated with the source code

3. Installing Json-c

[Email protected] json-c]$ sh build.sh

Then change the Ldflags =-LM in the generated makefile, and note that after each modification, make clean is simply to clear the previously compiled executable and configuration files. And make Distclean to clear all the generated files. ）

Make

Make install

Third, installation Libubox

1. Get Libubox

[[email protected] fl-easycwmp]$ git clone git://nbd.name/luci2/libubox.git./libubox

2. In the project Master CMakeLists.txt first add the following statement: (# #注意Linux第一个字母为大写, otherwise cmake do not know)

[Email protected] libubox]$ vim CMakeLists.txt

SET (Cmake_system_name Linux)
SET (Toolchain_dir "/OPT/BUILDROOT-2012.08/ARM920T/USR")
SET (Cmake_find_root_path ${toolchain_dir})
SET (Cmake_find_root_path_mode_program BOTH)
SET (cmake_find_root_path_mode_library "/home/weishusheng/fl-easycwmp/install/lib/")
SET (Cmake_find_root_path_mode_include only)
SET (Cmake_c_compiler ${TOOLCHAIN_DIR}/BIN/ARM-LINUX-GCC)
SET (Cmake_cxx_compiler ${toolchain_dir}/bin/arm-linux-g++)
SET (Cmake_install_prefix "/home/weishusheng/fl-easycwmp/install/")

3. Generate makefile

[Email protected] libubox]$ CMake Cmakelists.txt-dbuild_lua=off

4.make

Error Resolution:

Error 1

/home/weishusheng/fl-easycwmp/libubox/blobmsg_json.c:in function ' __blobmsg_add_json ':
/home/weishusheng/fl-easycwmp/libubox/blobmsg_json.c:78:2: error:implicit declaration of function ' Is_error '

Analysis: Is_error not defined, also encountered this problem when compiling on the PC, we know that his definition is # define IS_ERROR (PTR) (ptr = = NULL), then add the definition

[Email protected] libubox]$ VIM/HOME/WEISHUSHENG/FL-EASYCWMP/LIBUBOX/BLOBMSG_JSON.C

#include "Blobmsg.h"
#include "Blobmsg_json.h"
#define IS_ERROR (PTR) (ptr = = NULL)

Error 2

Cannot find-ljson-c

Specify JSON-C library path in CMakeLists.txt

[Email protected] libubox]$ vim CMakeLists.txt

Link_directories (/home/weishusheng/fl-easycwmp/install/lib/)

Error 3

/home/weishusheng/fl-easycwmp/libubox/jshn.c:in function ' Jshn_parse ':
/home/weishusheng/fl-easycwmp/libubox/jshn.c:162:2: error:implicit declaration of function ' Is_error '

Add definition

#define IS_ERROR (PTR) (ptr = = NULL)

4.

/home/weishusheng/cross_easycwmp/install/lib/libjson-c.so:undefined reference to ' __isnan '
/home/weishusheng/cross_easycwmp/install/lib/libjson-c.so:undefined reference to ' __isinf '

This problem makes me crazy, but you do not follow my blog do not appear this problem, because I wrote Json-c in front of the installation to solve for you, if you encounter a similar problem, you can try to compile json-c when adding

Export Ac_cv_have_decl_isinf=yes
Export Ac_cv_have_decl_isnan=yes

and connect to the math library that LDFLAGS+=-LM

Fourth. installation of UCI

1. Get UCI

[[email protected] fl-easycwmp]$ git clone git://nbd.name/uci.git./uci

2. Modify CMakeList.txt

[Email protected] uci]$ vim CMakeLists.txt
SET (Cmake_system_name Linux)
SET (Toolchain_dir "/OPT/BUILDROOT-2012.08/ARM920T/USR")
SET (Cmake_find_root_path ${toolchain_dir})
SET (Cmake_find_root_path_mode_program BOTH)
SET (Cmake_find_root_path_mode_library only)
SET (Cmake_find_root_path_mode_include only)
SET (Cmake_c_compiler ${TOOLCHAIN_DIR}/BIN/ARM-LINUX-GCC)
SET (Cmake_cxx_compiler ${toolchain_dir}/bin/arm-linux-g++)
SET (Cmake_install_prefix "/home/weishusheng/fl-easycwmp/install/")

Cmake_minimum_required (VERSION 2.6)

3. Generate makefile

[Email protected] uci]$ CMake Cmakelists.txt-dbuild_lua=off

4.make

/opt/buildroot-2012.08/arm920t/usr/lib/gcc/arm-unknown-linux-uclibcgnueabi/4.5.4/. /.. /.. /.. /arm-unknown-linux-uclibcgnueabi/bin/ld:cannot Find-lubox

Join Link_directories (/home/weishusheng/fl-easycwmp/install/lib/) in CMakeList.txt, problem solving

5.make Install

Fifth. Installation of Ubus

1. Get Ubus

git clone git://nbd.name/luci2/ubus.git./ubus

2. Modify CMakeList.txt

[Email protected] ubus]$ vim CMakeLists.txt
SET (Cmake_system_name Linux)
SET (Toolchain_dir "/OPT/BUILDROOT-2012.08/ARM920T/USR")
SET (Cmake_find_root_path ${toolchain_dir})
SET (Cmake_find_root_path_mode_program BOTH)
SET (Cmake_find_root_path_mode_library only)
SET (Cmake_find_root_path_mode_include only)
SET (Cmake_c_compiler ${TOOLCHAIN_DIR}/BIN/ARM-LINUX-GCC)
SET (Cmake_cxx_compiler ${toolchain_dir}/bin/arm-linux-g++)
SET (Cmake_install_prefix "/home/weishusheng/fl-easycwmp/install/")

3. Generate makefile

[Email protected] ubus]$ CMake Cmakelists.txt-dbuild_lua=off

CMake error:the Following variables is used in this project, but they is set to NOTFOUND.
Please set them or make sure they is set and tested correctly in the CMake files:
Json
Linked by target "CLI" in Directory/home/weishusheng/fl-easycwmp/ubus

Workaround: Specify the JSON library path in CMakeList.txt by modifying set (Cmake_find_root_path_mode_library only) to

SET (cmake_find_root_path_mode_library "/home/weishusheng/fl-easycwmp/install/lib") can be resolved.

4.make

Error: Cannot Find-lubox

Workaround: Add link_directories (/home/weishusheng/fl-easycwmp/install/lib) in cmakelists

Error: Json/json.h:no such file or directory

Workaround: Cross compile the default standard header file is under the cross compiler path, you can use echo ' main () {} ' |/opt/buildroot-

2012.08/ARM920T/USR/BIN/ARM-LINUX-GCC-E-V-command to view, we add the need to use the header file to the appeal command found location can be
, in addition, cross-compilation will go to the system default standard library directory to find the library file, which will cause the format is not met, we need to use the-L and-l to specify the library file

[[email protected] easycwmp]$ make

[[email protected] easycwmp]$ make install

At this point easycwmp cross-compile, then put on the FL2440 Development Board to run, on the Development Board to do the relevant settings, please refer to the next blog post.
