http://bugs.winehq.org/show_bug.cgi?id=59950 Bug ID: 59950 Summary: Shader compilation fails when starting Just Cause. Product: Wine Version: 11.10 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: d3d-util Assignee: wine-bugs@list.winehq.org Reporter: ldmwbjbipxjqwacdhk@kjkpc.net Distribution: --- Created attachment 81324 --> http://bugs.winehq.org/attachment.cgi?id=81324 Patch that fixes the issue Shader compilation fails when starting Just Cause. When I start Just Cause on Wine 11.10 or newer, I get 3 message boxes complaining about syntax errors. Title: Vertex shader error!

The game starts fine on Wine 11.0, 11.5, 11.7, 11.9, and probably older versions as well. Suspected cause: If I am reading the git log correctly, Wine 11.10 defaulted to builtin Direct3D libraries, instead of using the native libraries. This revealed a deficiency in the Direct3D shader parser. The problem seems to be that the game uses the exponent notation for some floating-point literals, but the Wine's parser grammar does not accept that. Proposed solution: A one line change to dlls/d3dcompiler_43/asmshader.l , that adds support for the exponent notation, seems to solve the problem. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
