Hello Gary, 

Thanks for responding. It does seem that I got a backtrace for the wrong thread.
In any case, yes it does look as if I should look for the answer within Wine.
Thank you. I'm sorry to be a distraction.

This looks like a backtrace of the initial thread; it indeed ordinarilyspends most of its time asleep (though I doubt if the alleged argumentsto SleepEx() in frame 3 have anything to do with how SleepEx() is actuallycalled.)Are you looking at this thread because:a) you have some reason to think that this has something to do with the reason that you're hanging orb) because this was the easiest thread to get a backtrace for?I have no idea what the problem actually is. To be honest, I'm not thatinterested unless there's some reason to think that it's a CCL bug. IfCCL was calling SleepEx with a large timeout value and a 0 "alertable"argument that would indeed be a bug in almost all cases that I can imagine;when I take a few seconds to grep through the sources, I can find no caseswhere it does so.On Tue, 23 Jul 2013, dto at blocky.io wrote:> Hi Gary,>> So I rebuilt Wine after commenting out one line.> But I may have run up against a wall.> wx86cl.exe runs, and I get to a working REPL.> But when trying do load ASDF or anything else,> ccl calls SleepEx and just waits (see line 3 of the backtrace below.)> After talking to a Wine developer, it looks like CCL is expecting to> be woken up sooner than that.>> Is it possible to configure this behavior from within the CCL process?>> Probably though it's something Wine doesn't account for;> but as the issue with the incorrect image-base was resolved with a one-line> change, I suspect that a relatively simple solution is possible here.>> Backtrace:> =>0 0x680011b0 in ld-linux.so.2 (+0x11b0) (0x0042fa18)> 1 0x7bc80243 NTDLL_wait_for_multiple_objects+0x232(count=0, handles=(nil), flags=0x6, timeout=0x42fcc8, signal_object=) [/home/dto/src/wine/dlls/ntdll/sync.c:1123] in ntdll (0x0042fc38)> 2 0x7bc8077e NtDelayExecution+0x19d(alertable=-88, timeout=(nil)) [/home/dto/src/wine/dlls/ntdll/sync.c:1209] in ntdll (0x0042fc98)> 3 0x7b8723cf SleepEx+0x3e(timeout=0x42fba8, alertable=0) [/home/dto/src/wine/dlls/kernel32/sync.c:108] in kernel32 (0x0042fcd8)> 4 0x0001a13d _SPffcall+0x54() [/usr/local/src/ccl-1.9/lisp-kernel/win32/../x86-spentry32.s:4326] in 2x0ng (0x0042fd08)> 5 0x0001a7ab _start_lisp+0x57() [/usr/local/src/ccl-1.9/lisp-kernel/win32/../x86-subprims32.s:119] in 2x0ng (0x0042fd28)> 6 0x0001c68b main+0x40c(argc=0x42fba8, argv=(nil)) [/usr/local/src/ccl-1.9/lisp-kernel/win32/../pmcl-kernel.c:2125] in 2x0ng (0x0042fd88)> 7 0x00011402 __tmainCRTStartup+0x281() [/usr/src/debug/mingw64-i686-runtime-3.0b_svn5452-1/crt/crtexe.c:315] in 2x0ng (0x0042fe60)> 8 0x7b85f20c call_process_entry+0xb() in kernel32 (0x0042fe78)> 9 0x7b86048b start_process+0x6a(peb=0x42fba8) [/home/dto/src/wine/dlls/kernel32/process.c:1084] in kernel32 (0x0042feb8)> 10 0x7bc78b40 call_thread_func_wrapper+0xb() in ntdll (0x0042fed8)> 11 0x7bc7bb4d call_thread_func+0x7c(entry=0x7b860420, arg=0x7ffdf000, frame=0x42ffc8) [/home/dto/src/wine/dlls/ntdll/signal_i386.c:2567] in ntdll (0x0042ffa8)> 12 0x7bc78b1e call_thread_entry_point+0x11() in ntdll (0x0042ffc8)> 13 0x7bc4e0be start_process+0x1d(kernel_start=0x7b860420) [/home/dto/src/wine/dlls/ntdll/loader.c:2694] in ntdll (0x0042ffe8)> 14 0x6802b7cd wine_call_on_stack+0x1c() in libwine.so.1 (0x00000000)> 15 0x6802b88b wine_switch_to_stack+0x2a(func=0x7bc4e0a0, arg=0x7b860420, stack=0x430000) [/home/dto/src/wine/libs/wine/port.c:59] in libwine.so.1 (0xbfe984a8)> 16 0x7bc53f60 LdrInitializeThunk+0x3af(kernel_start=0x42fba8, unknown2=0, unknown3=0x102, unknown4=0) [/home/dto/src/wine/dlls/ntdll/loader.c:2750] in ntdll (0xbfe98518)> 17 0x7b8669e2 __wine_kernel_init+0xa21() [/home/dto/src/wine/dlls/kernel32/process.c:1256] in kernel32 (0xbfe996c8)> 18 0x7bc5471b __wine_process_init+0x25a() [/home/dto/src/wine/dlls/ntdll/loader.c:2959] in ntdll (0xbfe99758)> 19 0x68028d3c wine_init+0x28b(argc=0x2, argv=0xbfe99ca4, error="", error_size=0x400) [/home/dto/src/wine/libs/wine/loader.c:847] in libwine.so.1 (0xbfe997b8)> 20 0x7bf00cfb main+0x8a(argc=, argv=) [/home/dto/src/wine/loader/main.c:237] in  (0xbfe99c08)> 21 0x6820b4d3 __libc_start_main+0xf2(main=0x7bf00c70, argc=0x2, ubp_av=0xbfe99ca4, init=0x7bf01050, fini=0x7bf010c0, rtld_fini=0x6800f280, stack_end=0xbfe99c9c) [/build/buildd/eglibc-2.15/csu/libc-start.c:226] in libc.so.6 (0x00000000)>>> -----Original Message-----> From: Gary Byers [mailto:gb at clozure.com]> Sent: Monday, July 22, 2013 12:35 PM> To: dto at blocky.io> Cc: openmcl-devel at clozure.com> Subject: Re: [Openmcl-devel] question about "linker tricks" and "VirtualProtect spjump" error under Wine>> The linker tricks in question are: - passing the --image-base 0x10000 argument to ld.exe in ccl/lisp-kernel/win64/Makefile - telling ld.exe to use a linker script ("pei-x86-64.x") - in that linker script, reserving another 64K bytes between the (page-aligned) end of the executable file's headers and the start of its acual code,The intent is that the memory between #x11000 and #x21000 is mapped(readonly) and otherwise unused. We can achieve this effect in otherways on other platforms. remap_spjump() tries to write-enable a pagein this memory region (IIRC, at #x14000) so that something else canbe copied to that fixed address, and that fails under WINE. I'd guessthat the failure is caused by WINE's failure to have mapped the executableat the specifed image-base address in the first place, but that's justa guess.On Mon, 22 Jul 2013, dto at blocky.io wrote:> Greetings, Clozure CL community.> > I have a question about the "linker tricks" described near remap_spjump() in> the CCL so! urce:> ??> ? ?http://svn.clozure.com/publicsvn/openmcl/trunk/source/lisp-kernel/pmcl-kern> el.c> > When attempting to run the Windows version of CCL under Wine 1.6, the> following error message results:> ?> ???
