Redis6 source code mode

Installing Cygwin

1. Download and install Cygwin

Go to Cygwin's official website http://www.cygwin.com/

window 64 bit, please select setup-x86_64.exe 32-bit, please select setup-x86.exe After downloading exe, run setup.exe Exe program, the installation screen appears, as shown in the following figure:

The above steps suggest the next step by default.

2. Key steps

In this step, it should be noted that in order to obtain the fastest download speed, three download addresses are provided

First, find the address of Cygwin China image in the list: http://www.cygwin.cn/
Alicloud image http://mirrors.aliyun.com/cygwin/
163 mirroring http://mirrors.163.com/cygwin/

Here, take 163 image as an example. After selecting, click next,

Next, select the installed software and Search GCC core, gcc-g + +, make, gdb and binutils respectively in the Search,

Select the relevant version in the devel directory, and select Reinstall to download again.

Then the next step, the next step, depends on your network speed. Wait for the download to succeed.

3. Verify that Cygwin was successfully installed

Run cygwin and enter cygcheck -c cygwin in the pop-up command line window

Also install an apt Cyg (equivalent to yum under linux and no yum command under cygwin)

After installing apt Cyg, you can use the apt get install / remove command to install and uninstall the software like using Ubuntu. It is very convenient. GitHub download script: https://github.com/transcode-open/apt-cyg

Copy apt Cyg, paste it into the bin directory of the cygwin installation directory, and then execute the command

Then add the configuration in the system variable

Install clion

clion is a new C/C + + cross platform integrated development environment launched by JetBrains. java programmers who are used to using idea should be more comfortable debugging redis source code with clion, which is much more comfortable than vc.

Import redis source code from Clion

Before importing the IDS source code, you need to add a cmakelists txt

/CMakeLists.txt
./deps/CMakeLists.txt
./deps/linenoise/CMakeLists.txt
./deps/lua/CMakeLists.txt
./src/modules/CMakeLists.txt

Before compiling, you need to execute mkreleasehdr on Cygwin64 Terminal SH script. Because the script format is in win format, it needs to execute the conversion of dos2unix commands, and then execute it after the conversion

##Conversion format
dos2unix mkreleasehdr.sh
##Execute mkreleasehdr sh
./mkreleasehdr.sh

Compile & debug redis6 source code

1) After the redis6 source code is loaded, cmake will compile automatically. After compilation, select the redis server debug option and click [run]

If you want to the breakpoint, download a windows client of reids cli.

The breakpoint results are as follows:
