Created attachment 444004 [details, diff] Fix that temporarily unsets EGIT_COMMIT Due to using the egit eclass for fetching both WINE and the staging sources, the latter inherits the same EGIT_COMMIT value and thus fails. I've included a patch which temporarily unsets EGIT_COMMIT while fetching the staging sources.
Please attach the failing build log or at least enough of it to support the patch.
Fix is staged and will be out as soon as I can finish up my wine related edits today
Fixed in ba956c8e2dcedd1265a19432fc38297c4d6e2e8c. EGIT_COMMIT usage has been disabled in wine due to the collisions of multiple repos. WINE_COMMIT, STAGING_COMMIT, and D3D9_COMMIT may be used.
Sorry for not attaching the build log earlier, but I assumed that the build failure itself was not of great importance - it fails while applying patches from staging/D3D. I was about to add that the patch did not take care of the D3D git fetch and would fail similarly, but it seems a more elegant fix was already in-tree. Thanks!
