移植rabbitMQ-C

按照文档README.md的说法建立  mkdir build

cd build

cmake ..

然后修改CMakeCach.txt，根据编译链的实际情况，以及调试过程中需要的库，做出修改，其中红色部分是需要修改的地方。

# This is the CMakeCache file.
# For build in directory: /rabbitmq-c-arm2/build
# It was generated by CMake: /usr/local/bin/cmake
# You can edit this file to change values found and used by cmake.
# If you do not want to change any of the values, simply exit the editor.
# If you do want to change a value, simply edit, save, and exit the editor.
# The syntax for the file is as follows:
# KEY:TYPE=VALUE
# KEY is the name of a variable in the cache.
# TYPE is a hint to GUI's for the type of VALUE, DO NOT EDIT TYPE!.
# VALUE is the current value for the KEY.

修改完后运行 cmake --build .

在编译过程中，自带的OPENSSL库不能用，自己重新编译了一个，就ok了。

如果嫌配置CmakeCache.txt麻烦，可以用以下的方法：

在rabbitMQ-c-master目录中建立build目录

把ToolChain.cmake放入其中

在build目录下

cmake-DCMAKE_TOOLCHAIN_FILE=./ToolChain.cmake ..

注意此处的".."

ToolChain.cmake为

set(CMAKE_SYSTEM_NAME Linux)


set(CMAKE_SYSTEM_VERSION 1)
set(CMAKE_C_COMPILER  "/opt/mv_pro_4.0.1/montavista/pro/devkit/arm/v5t_le/bin/arm_v5t_le-gcc")
