Hello All, I was checking the latest git wine source and I had the below error message: checking gst/gst.h usability... no checking gst/gst.h presence... yes configure: WARNING: gst/gst.h: present but cannot be compiled configure: WARNING: gst/gst.h: check for missing prerequisite headers? configure: WARNING: gst/gst.h: see the Autoconf documentation configure: WARNING: gst/gst.h: section "Present But Cannot Be Compiled" configure: WARNING: gst/gst.h: proceeding with the compiler's result configure: WARNING: ## ------------------------------------ ## configure: WARNING: ## Report this to wine-devel@winehq.org ## configure: WARNING: ## ------------------------------------ ## checking for gst/gst.h... no As the error message said I should report this to wine-devel, I am writing this email. I use Slackware-current update (actually Slackware 15 RC1 now). My gstreamer version is 1.18.4 and I checked the build scripts and there's no upstream patches applied. Gcc version is 11.2.0 if any other questions, please ask and I will provide information. Regards, Ozan
