WHAT'S NEW with Wine-20040615: (see ChangeLog for details) - Major winedbg rewrite using the dbghelp dll. - New Wine preloader to reserve memory areas at startup.
On FreeBSD 4.x, I'm now getting the following when trying to invoke Wine, even without any parameters:
wine: failed to initialize: /swtest/wine/dlls/ntdll.dll.so: mmap of entire address space failed: Cannot allocate memory
I think this is caused by FreeBSD's mmap behaviour differing from that of Linux. From my reading of the code, it looks like Wine (now) tries to snaffle as much memory above 0x80000000 as it can to reserve it. When allocating memory without specifying a base address, FreeBSD appears to try to allocate memory above the locations it has allocated before, i.e. up in the region beyond where it has snaffled everything. The error quoted above comes from the dlopen() function in rtld.
Using the current CVS sources, I tried nobbling the reservation code by turning the functions into nops. I also had to comment out the section in map_view() where there is a test if the allocated memory is above the user address limit. That allows notepad to get through all the initialisation without barfing. [ It then goes into an infinite loop trying to open the display. 8-( ]
