linux下编译jrtplib-3.9.1
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
網站：http://blog.csdn.net/caoshangpa/article/details/51416822
一、下載jrtplib、jthread、CMake
jrtplib：http://research.edm.uhasselt.be/jori/jrtplib/jrtplib-3.9.1.zip
jthread：http://research.edm.uhasselt.be/jori/jthread/jthread-1.3.1.zip
CMake：https://cmake.org/download/，最新版已經到3.5.1，我用的是3.4.0
注意，如果jrtplib編譯過程中報錯/usr/bin/ld:cannot find -lIN，參考：http://blog.csdn.NET/caoshangpa/article/details/51416500
二、編譯
1.jthread編譯
修改CMakeLists.txt，如下所示，注意添加的部分。
[cpp]?view plaincopy
cmake_minimum_required(VERSION?2.6)?? ?? project(jthread)?? set(VERSION?1.3.1)?? #************************************添加開始******************************?? #告知當前使用的是交叉編譯方式???? SET(CMAKE_SYSTEM_NAME?Linux)???? #設置c編譯器???? SET(CMAKE_C_COMPILER?"gcc")???? #設置c++編譯器????

cmake CMakeLists.txt
make
make install
2.jrtplib編譯
修改CMakeLists.txt，如下所示，注意添加和修改的部分。
