[play with Huawei cloud] Kunpeng devkit migration practice

1. Preface

Kunpeng development kit DevKit Provide migration for the entire R & D workflow 、 Code development 、 Compile debugging 、 test 、 Performance analysis and tuning 、 System diagnosis and other capabilities , Realize rapid migration and minimalist development of massive applications to Kunpeng platform , It is convenient for developers to quickly develop Kunpeng friendly high-performance software .

2. actual combat

2.1 Actual combat content

Use the scan migration tool for source code analysis , Modify the source code according to the scanning suggestions , Let the source code compile and run normally on the Kunpeng platform .

2.2 Premise of operation

2.2.1 Application resources

2.2.3 Source download

1） Get into “ Kunpeng code migration tool ” Source file storage path .

cd /opt/portadv/portadmin/sourcecode/

2） download Megahit Source code .

git clone https://github.com/voutcn/megahit.git

3） Merge the code .

cd megahit/ && git submodule update

4） Create the build folder and go to .

mkdir build && cd build

Tips ： Manual installation is required here cmake

5） Generate Makefile file .

cmake -DCMAKE_BUILD_TYPE=Release

6） modify megahit Catalogue group .

cd …/ && chown -R porting:porting *

3. Code migration

Log in to the migration website platform https://172.36.86.41:8084/

1） Source code analysis parameter filling

2） Start a source migration task , The task was executed successfully , View the source code report .

Click start analysis

The lower left corner can display the progress of source migration analysis

The compiler version can only be selected here GCC, Unable to select the Pentium compiler in the legend

After the report is generated, click View report

3） Click report source code migration suggestions , View the files to be migrated .

4） Modify according to the modification suggestions prompted by the system .

5） Recompile after migration , View the compilation results .

6） Run the program , View echo information .

4. Experimental experience

4.1 cmake install

You need to configure yourself in the experiment cmake Environmental Science

1. download cmake-3.12.2.tar.gz:

wget https://github.com/Kitware/CMake/releases/download/v3.13.2/cmake-3.13.2.tar.gz

2. decompression :

tar -zxvf cmake-3.13.2.tar.gz

3. Go to unzip directory :

cd cmake-3.13.2

4. Execute the command to install ：

./bootstrap && make && make install

5. View version information , And check if the installation is successful

cmake -version

After studying this article , Have a certain understanding of cross platform software migration , At the same time, master the use of code migration tools , Be able to skillfully use migration tools to perform migration tasks .
