dlt-daemon安装教程

获取dlt-daemon源码

git clone https://github.com/GENIVI/dlt-daemon.git
cd dlt-daemon
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

dlt-daemon 编译安装就完成了。

批注： linux下使用sudo apt install dlt-daemon是不是也可以？？

dlt-viewer

现装依赖包 sudo apt-get install libqt5serialport5-dev libqt5serialport5
批注：也可以使用 sudo apt install dlt-viewer 完成安装。

git clone https://github.com/GENIVI/dlt-viewer.git
mkdir build
cd build
cmake ..
make

这时，build/bin目录下就生成了可执行文件dlt-viewer

生成测试程序

cd dlt-daemon/examples/example1/
mkdir build
cd build
cmake ..
make

dlt-example1的测试程序就生成好了。具体如何添加dlt_log就餐控example下的几个例子。

启动dlt-daemon

首先复制dlt.conf文件

cd dlt-daemon/src/daemon/
sudo cp dlt.conf /etc/
sudo gedit /etc/dlt.conf

修改dlt.conf：

LoggingMode = 2
OfflineTraceDirectory = /tmp
OfflineTraceFileSize = 1000000
OfflineTraceMaxSize = 4000000
 
OfflineTraceFileNameTimestampBased = 1
OfflineLogstorageDirPath = /opt

链接配置文件：

dlt-daemon -c /etc/dlt.conf

启动log接收端：

dlt-receive -o /tmp/log.dlt localhost

启动example1:

dlt-daemon/examples/example1/build$ sudo ./dlt-example1

这时，/tmp/log.dlt 文件就可以用dlt-viewer查看啦。

自定义样例

在home建立test文件夹,然后写入
example.c

#include 
#include 
 
DLT_DECLARE_CONTEXT(myContext1);
DLT_DECLARE_CONTEXT(myContext2);
DLT_DECLARE_CONTEXT(myContext3);
 
int main()
{
/* register application */
DLT_REGISTER_APP("MAPP","Test Application for Logging");
 
/* register all contexts */
DLT_REGISTER_CONTEXT(myContext1,"TES1","Test Context 1 for Logging");
DLT_REGISTER_CONTEXT(myContext2,"TES2","Test Context 2 for Logging");
DLT_REGISTER_CONTEXT(myContext3,"TES3","Test Context 3 for Logging");
 
/* Write your logs */
DLT_LOG(myContext1,DLT_LOG_ERROR,DLT_INT(5),DLT_STRING("This is a error"));
DLT_LOG(myContext2,DLT_LOG_INFO,DLT_INT(5),DLT_STRING("But this only information"));
DLT_LOG(myContext3,DLT_LOG_DEBUG,DLT_INT(5),DLT_STRING("But this only information"));
 
/* Sleep some time to avoid a flaw in dlt-daemon that would eat your messages
 if you deregister while it still processes your registration */
sleep(3);
 
/* unregister your contexts */
DLT_UNREGISTER_CONTEXT(myContext1);
DLT_UNREGISTER_CONTEXT(myContext2);
DLT_UNREGISTER_CONTEXT(myContext3);
 
/* unregister your application */
DLT_UNREGISTER_APP();
 
return 0;
 
}

构建工程

cd test
mkdir build
cd build
cmake ..
make
dlt-receive -o /tmp/log.dlt localhost
sudo ./dlt-example1

此时就可以使用dltViewer查看 /tmp/log.dlt
