Go exe generates icon version information

Why add icons and details
As a desktop program , There is an icon , Be more formal . The detailed information has a version number to facilitate version identification . Forget it , I can't make it up . No matter how much , Anyway, others have these , You should have these functions ( but ).golang As a back-end language , Yes windows Interface programming support is not so friendly , It is difficult to add icons and details directly . Fortunately, there is a third-party library –GoVersionInfo, It can help us solve this problem .
 

GoVersionInfo Is used for Go Linguistic Microsoft Windows File attribute / Version information and icon resource generator

The package will create a syso file , It includes Microsoft Windows Version information and an optional icon . When you run “ go build” when ,Go Version information as well as optional icons and optional lists will be embedded in the executable . If it's with main（） Functions are located in the same directory , be Go Will be used automatically syso file .

install GoVersionInfo

go get github.com/josephspurrier/goversioninfo/cmd/goversioninfo

Download the just downloaded GoVersionInfo The catalog of github.com\josephspurrier\goversioninfo\testdata\resource Copy to our project directory (main.go In the directory ). And put versioninfo.json Copy to and main.go Same as catalog .
 

Modify file

stay main.go Add... To the first line of ：

main.go  Add notes  
//go:generate goversioninfo -icon=jiuwei.ico -manifest=main.exe.manifest

Then modify and main.go Under the same level of directory versioninfo.json file . Put the fields inside “ProductVersion” Change to the version number you want .（ You can also modify other information, such as : Copyright , The product name , Document description, etc ）

First use ,go generate Command to generate resource.syso Resource file

Reuse ,go build Command to generate EXE file . You need to use Directory The way to compile , Out-of-service File The way to compile .（ That is to say, it can't be used go build main.go This way, ）. The reason is through Directory The way to compile , The compiler will automatically find the resource files in the same directory and package them into EXE.
During the compilation process , You may encounter errors
 

C:\Go\pkg\tool\windows_amd64\link.exe: running gcc failed: exit status 1
C:/Program Files/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: i386 architecture of input file `C:\Users\hjd\AppData\Local\Temp\go-link-681106599\000000.o' is incompatible with i386:x86-64 output
collect2.exe: error: ld returned 1 exit status

The above solution is , Compile with parameters

-ldflags="-linkmode internal"

go build -o myapp.exe -ldflags="-linkmode internal" -ldflags="-H windowsgui"

go build -o ./myapp.exe -ldflags="-linkmode internal" -ldflags="-H windowsgui"

The reason why I have  -ldflags="-H windowsgui" Is to cancel the black window the reason being that GUI Interface
