Thanks Philippe, Sorry for the late follow up. I got side tracked. What's
the best way to build and play with wpe in an uninstalled env? I use
gst-build but when I try to buid wpewebkit it needs gstreamer. When I try
to build wpewebkit inside gst-build env it fails. (1.16 branch)
Example error:
/data/dev/gst-build/subprojects/gst-plugins-base/gst-libs/gst/audio/audio-info.h:139:1:
error: ‘GST_API_IMPORT’ does not name a type; did you mean
‘GST_URI_NO_PORT’?
GST_AUDIO_API
What would be the best way? What I am missing?
Thanks
