Running into "flag provided but not defined: -coverprofile" about gocov HOT 3 CLOSED

That looks a lot like you're using a version of Go < 1.2. Gocov was changed about 3 months ago to use (and require) the coverage support introduced in Go 1.2.

Thanks, You are right. On upgrading go version from 1.1.1 to 1.2, I am no longer seeing earlier faced errors. But it now looks like I can run gocov for a single package and not for for multiple packages in one command.

On running gocov test <list of packages>, I run into following errors.
"cannot use test profile flag with multiple packages
error: %v exit status 1"

Is there a different way to get gocov working for multiple packages?

Unfortunately support for testing multiple packages at once was lost in the move to using the 1.2 coverage features. What I would suggest is to run "go test -coverprofile= " for each package, and then combine all of the profiles into one gocov profile with "gocov convert <profile.0> <profile.1> ... <profile.N>".

I'll close this issue as the original problem is resolved, but feel free to continue the discussion of multiple packages.
