交叉編譯jrtplib 問題

問題描述：

1、安裝包：jrtplib-3.7.1.tar.gz  jthread-1.2.1.tar.gz

2、步驟：分別解壓兩個安裝包

進入jthread-1.2.1使用./configure -host=arm-linux cc=arm-linux-gcc cxx=arm-linux-g++ 命令配置

make

make install

同樣進入

jrtplib-3.7.1 使用同樣步驟

3、錯誤資訊

rtppollthread.cpp:(.text+0x484): undefined reference to `jthread::~jthread()'

rtppollthread.cpp:(.text+0x4a4): undefined reference to `jmutex::~jmutex()'

rtppollthread.cpp:(.text+0x4ac): undefined reference to `jthread::~jthread()'

collect2: ld returned 1 exit status

配置jrtplib的命令改為

./configure -host=arm-linux cc=arm-linux-gcc cxx=arm-linux-g++ --with-jthread-include=/usr/local/include/jthread ldflags=-l/usr/local/lib 就ok了
