dlt-daemon安裝教程

獲取dlt-daemon源碼

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 編譯安裝就完成了。

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

dlt-viewer

現裝依賴包 sudo apt-get install libqt5serialport5-dev libqt5serialport5
批注：也可以使用 sudo apt install dlt-viewer 完成安裝。

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

這時，build/bin目錄下就生成了可執行文件dlt-viewer

生成測試程序

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

dlt-example1的測試程序就生成好了。具體如何添加dlt_log就餐控example下的幾個例子。

啟動dlt-daemon

首先復制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

鏈接配置文件：

dlt-daemon -c /etc/dlt.conf

啟動log接收端：

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

啟動example1:

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

這時，/tmp/log.dlt 文件就可以用dlt-viewer查看啦。

自定義樣例

在home建立test文件夾,然后寫入
example.c

#include <stdio.h>
#include <dlt.h>

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;

}

構建工程

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

此時就可以使用dltViewer查看 /tmp/log.dlt
