go ldflags set variable value not working
0
I'm trying to use go build to update a variable inside my project:
full project path:
c:goprojectssrcdeploymentclappsappName
run from c:goprojectssrc
go install -ldflags="-X main.GitRev=adaf66c" deploymentclappsappName...
In the go project I have:
package main
var GitRev = "oldvalue"
func main() {
fmt.Println("variable contents: ", GitRev)
}
Then from the command line I run:
..binappName.exe
I'm expecting to see the value:
adaf66c
What I get: variable contents:
oldvalue

Are you sure you are running the binary you just built?

yes, I can change the value of GitRev from 'oldvalue' to 'oldvalue1' and see that it changes the next time I build the appName.exe binary

I took your code, and: 1)➜ go build -ldflags="-X main.GitRev=adaf66c"2)➜ ./so-53402640 variable contents: adaf66c(it's linux though)

ya it should work. maybe related to the paths. I also have a large project with many imports too, but shouldn't matter.

I believe you are just declaring a variable and not a flag. Import the flag package and assign it like so.
import "flag"
var GitRev = flag.String("GitRev", "oldvalue", "what it represents")
