Cannot build projects using gocv after upgrading to v0.38.0.

Description

When building a simple project with go using gocv v0.38.0, it returns the stack trace below:

Steps to Reproduce

  1. Open new project and create a main.go file: 
    
package main

import ( "fmt" "gocv.io/x/gocv" "io" "os" )

func main() { f, err := os.Open("/path/to/an/image") if err != nil { fmt.Println(err) return } defer f.Close()

content, err := io.ReadAll(f)
if err != nil {
    fmt.Println(err)
    return
}

dstMat := gocv.NewMat()
srcMat, err := gocv.IMDecode(content, gocv.IMReadColor)
if err != nil {
    fmt.Println(err)
    return
}

gocv.CvtColor(srcMat, &dstMat, gocv.ColorBGRToRGB)
return

}

2. Build it with:
```shell
go build .

It failed.

Your Environment

deadprogram commented 3 days ago

That sounds like an incompatible version of OpenCV being installed by python, or installed missing required module.

Perhaps you can check pkg-config command output. In any case, the only tested installation for Linux is installing OpenCV from source.
