cannot convert sync (type glbase.Sync) to type _Ctype_GLsync

[marguerite]

Hi,

I'm building go-qml on openSUSE 13.1, using golang 1.3 (default one).

here's what I get:

[ 379s] gl/4.2core/gl.go:2330[/tmp/go-build998181402/gopkg.in/qml.v1/gl/4.2core/_obj/gl.cgo1.go:1126]: undefined: INFO_LOG_LENGTH [ 379s] gl/4.2core/gl.go:2396[/tmp/go-build998181402/gopkg.in/qml.v1/gl/4.2core/_obj/gl.cgo1.go:1146]: undefined: INFO_LOG_LENGTH [ 379s] gl/4.2core/gl.go:3813[/tmp/go-build998181402/gopkg.in/qml.v1/gl/4.2core/_obj/gl.cgo1.go:1885]: cannot convert sync (type glbase.Sync) to type _Ctype_GLsync [ 379s] gl/4.2core/gl.go:3823[/tmp/go-build998181402/gopkg.in/qml.v1/gl/4.2core/_obj/gl.cgo1.go:1897]: cannot convert sync (type glbase.Sync) to type _Ctype_GLsync [ 379s] gl/4.2core/gl.go:3828[/tmp/go-build998181402/gopkg.in/qml.v1/gl/4.2core/_obj/gl.cgo1.go:1903]: cannot convert sync (type glbase.Sync) to type _Ctype_GLsync [ 379s] gl/4.2core/gl.go:3834[/tmp/go-build998181402/gopkg.in/qml.v1/gl/4.2core/_obj/gl.cgo1.go:1910]: cannot convert sync (type glbase.Sync) to type _Ctype_GLsync [ 379s] gl/4.2core/gl.go:3839[/tmp/go-build998181402/gopkg.in/qml.v1/gl/4.2core/_obj/gl.cgo1.go:1916]: cannot convert sync (type glbase.Sync) to type _Ctype_GLsync [ 379s] gl/4.2core/gl.go:3846[/tmp/go-build998181402/gopkg.in/qml.v1/gl/4.2core/_obj/gl.cgo1.go:1924]: cannot convert glresult (type _Ctype_GLsync) to type glbase.Sync

I don't know golang that deep...I just need to package go-qml for limetext dependency :-)...so please tell me why I was wrong...

Thanks

Sorry for the trouble. I'll address these issues shortly.

Please try updating. Change e3d7ffdc should have fixed this.

As a side note if you decide to hack further on those packages, they are all automatically generated by the tool in gl/gengl.
