--- Comment #11 from VitorMM vitormm@portingkit.com --- Confirming: the method mentioned above works. I could create a wine prefix with Wine Staging 2.20 and install Steam in it after replacing this: #define LDT_FIRST_ENTRY 512 #define LDT_SIZE 8192
With this: #define LDT_FIRST_ENTRY 3 #define LDT_SIZE 127
Thanks to Ken Thomases for finding the workaround for the bug and to Gijs Vermeulen for compiling Wine with the change so I could test it :)
