autoconf help needed [was wineps include fix.]

On Red Hat 7.1, for example, they're in /usr/include/freetype2/freetype, to distinguish them from the FreeType 1.x headers. The required compiler flag to include the proper directories is in the FREETYPEINCL variable. For example, on my Red Hat system it is set to '-I/usr/include/freetype2'. I tried the following: ft_incl_dir=${FREETYPEINCL#-I} AC_CHECK_HEADER("$ft_incl_dir/freetype/freetype.h",AC_DEFINE(HAVE_FREETYPE_H)) When I run autoconf, autoheader, and configure, I get the following: checking for FT_Init_FreeType in -lfreetype... yes checking for freetype-config... freetype-config checking for /usr/include/freetype2/freetype/freetype.h... no So the AC_CHECK_HEADER macro isn't finding the file, even though it is right there. Anyone have any idea why? -- ======================================================================== Ian Pilcher ian.pilcher(a)home.com ========================================================================

The page at http://freetype.sourceforge.net/freetype2/docs/tutorial/step1.html says that you have to include ft2build.h and use macros to include freetype.h, and that other inclusion schemes will get broken in 2.1. I have no idea if this page is up-to-date or if the recommendations have changed again. > We still have to test which macros are defined and only include the ones > that exist, but it does save the work of adding extra autoconf checks. Except with the autoconf checks we control what macros are being defined, we don't have to guess which file to include to get the proper macros. Frankly this idea of defining macros to specify include file names is hopelessly brain-damaged, and the less we have to do with that the happier I will be. -- Alexandre Julliard julliard(a)winehq.com

For you certainly. But it doesn't have to be in CVS for you to use it, does it? These kinds of quick hacks have a way of staying around much too long, especially when external packages depend on them, and the best way to avoid that is to not put them in CVS the first place. -- Alexandre Julliard julliard(a)winehq.com

It seems the rule is now to use ft2build.h instead of freetype.h. And this will certainly change in the next release again... so yes, it will be a nightmare if we actually try to use the silly macros. But if we simply bypass them and do autoconf checks like we do for every other package, I think it should work, and be harder to break (though I'm sure the freetype guys will manage to do it ;-) Basically do a AC_CHECK_HEADERS(freetype/freetype.h freetype/foo.h freetype/bar.h) and then #ifdef HAVE_FREETYPE_FREETYPE_H #include <freetype/freetype.h> #endif #ifdef HAVE_FREETYPE_FOO_H #include <freetype/foo.h> #endif etc. Then when they change all the header names again in the next release we can simply add the new names to the list. -- Alexandre Julliard julliard(a)winehq.com

How about doing autoconf checks for all the possible header names variations, and including the ones we find? This would be a lot more robust than trying to find the header that defines the macros that define the headers that define what we need... -- Alexandre Julliard julliard(a)winehq.com

Problems with large file support.
by Ludovic LANGE 30 May '01

30 May '01

Hello, A few days ago (15 or 16) the support for large files / 64bits was added to Wine ( files/files.c, server/file.c, win32/file.c). Since that modification, my Wine installation isn't functional any more, and wine throws an exception while setting up the SystemHeap. The exception occurs in heap.c, function HEAP_InitSubHeap, just at the instruction : "subheap->heap = heap;" while the subheap pointer is valid. It seems as if the protection of this memory areay was set to read-only, and that the mprotect() call did not succeed in setting it to read/write. I don't know where the real problem is, but since I found no record of such problem in the lists archive, it may be a configuration problem of mine. However, having not found the solution, I'd like some advices. I also think it could be a problem with my glibc not functionning with 64bits functions. My system is a Linux 2.4.4 / RedHat 7.0 / redhat's glibc 2.2-12 Here is a working trace, before the support for 64bits functions was added : ============================================================================== 0806cb00:trace:virtual:CreateFileMappingA (ffffffff,(nil),08000004,0000000000110000,"__SystemHeap") 0806cb00: create_mapping( size_high=0, size_low=1114112, protect=67, inherit=0,file_handle=0, name=L"__SystemHeap" ) 0806cb00: create_mapping() = 0 { handle=32 } 0806cb00: get_mapping_info( handle=32 ) 0806cb00: get_mapping_info() = 0 { size_high=0, size_low=1114112, protect=67, header_size=0, base=(nil), shared_file=0, shared_size=0 } 0806cb00: get_handle_fd( handle=32, access=00000000 ) 0806cb00: *fd* 32 -> 9 0806cb00: get_handle_fd() = 0 { fd=-1 } 0806cb00: set_handle_info( handle=32, flags=0, mask=0, fd=6 ) 0806cb00: set_handle_info() = 0 { old_flags=0, cur_fd=6 } 0806cb00:trace:virtual:MapViewOfFileEx handle=20 size=110000 offset=0 0806cb00: dup_handle( src_process=-1, src_handle=32, dst_process=-1, access=00000000, inherit=0, options=2 ) 0806cb00: dup_handle() = 0 { handle=36, fd=-1 } View: 65430000 - 6553ffff 36 65430000 - 6553ffff c-rW- 0806cb00:trace:virtual:VirtualAlloc 65430000 00110000 1000 00000040 0806cb00:trace:virtual:VIRTUAL_SetProt 65430000-6553ffff c-rWx View: 65430000 - 6553ffff 36 65430000 - 6553ffff c-rWx 0806cb00: create_semaphore( initial=00000000, max=00000001, inherit=0, name=L"") ============================================================================== Here is the stack trace with support for 64 bits functions (more debug traces of mine.) ============================================================================== 0806cb40:trace:virtual:CreateFileMappingA (ffffffff,(nil),08000004,0000000000110000,"__SystemHeap") 0806cb40: create_mapping( size_high=0, size_low=1114112, protect=67, inherit=0, file_handle=0, name=L"__SystemHeap" ) 0806cb40: create_mapping() = 0 { handle=32 } 0806cb40:trace:heap:HEAP_CreateSystemHeap LLA 0806cb40: get_mapping_info( handle=32 ) 0806cb40: get_mapping_info() = 0 { size_high=0, size_low=1114112, protect=67, header_size=0, base=(nil), shared_file=0, shared_size=0 } 0806cb40: get_handle_fd( handle=32, access=00000000 ) 0806cb40: *fd* 32 -> 9 0806cb40: get_handle_fd() = 0 { fd=-1 } 0806cb40: set_handle_info( handle=32, flags=0, mask=0, fd=6 ) 0806cb40: set_handle_info() = 0 { old_flags=0, cur_fd=6 } 0806cb40:trace:virtual:MapViewOfFileEx handle=20 size=110000 offset=0 0806cb40: dup_handle( src_process=-1, src_handle=32, dst_process=-1, access=00000000, inherit=0, options=2 ) 0806cb40: dup_handle() = 0 { handle=36, fd=-1 } View: 65430000 - 6553ffff 36 65430000 - 6553ffff c-rW- 0806cb40:trace:heap:HEAP_CreateSystemHeap LLA - after MapViewOfFileEx : 1077 0806cb40:trace:heap:HEAP_CreateSystemHeap LLA - line 1081 0806cb40:trace:heap:HEAP_InitSubHeap LLA address = 65430000 - line 478 0806cb40:trace:heap:HEAP_InitSubHeap LLA - line 482 0806cb40:trace:virtual:VirtualAlloc 65430000 00110000 1000 00000040 0806cb40:trace:virtual:VIRTUAL_SetProt 65430000-6553ffff c-rWx View: 65430000 - 6553ffff 36 65430000 - 6553ffff c-rWx 0806cb40:trace:virtual:VirtualAlloc LLA 65430000 00110000 1000 00000040 VIRTUAL_SetProt : base= 65430000 0806cb40:trace:heap:HEAP_InitSubHeap LLA - line 491 0806cb40:trace:heap:HEAP_InitSubHeap LLA subheap = 65430000 - line 518 0806cb40:trace:seh:EXC_RtlRaiseException code=c0000005 flags=0 0806cb40: queue_exception_event( first=1, record={context={flags=00000000,eax=00000047,ebx=4012c0ec,ecx=65430000,edx=65430000,esi=40128e05,edi=00110000,ebp=00000000,eip=400bb7eb,esp=40626dd0,eflags=00010212,cs=0023,ds=002b,es=002b,fs=008f,gs=0000,dr0=00000000,dr1=00000000,dr2=00000000,dr3=00000000,dr6=00000000,dr7=00000000,float={00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000}},rec={code=c0000005,flags=0,rec=(nil),addr=0x400bb7eb,params={1,65430010} ) 0806cb40: queue_exception_event() = 0 { handle=0 } ============================================================================== Any clues are welcome.

The main problem is that this requires linking the application to x11drv, which is not a good idea. x11drv is an internal driver that should only be loaded by user/gdi. There needs to be a way to do that without loading x11drv, for instance by using window properties. This is somewhere on my todo list for the new window management code that I'm currently working on. -- Alexandre Julliard julliard(a)winehq.com

some unimplemented COM stuff
by Malte.Starostik＠t-online.de 30 May '01

30 May '01

Hello, I have started implementing a small winelib-program that shall eventually add ActiveX support to the Konqueror web browser. For testing I'm using the Shockwave Flash OCX and experienced some problems due to unimplemented functions and features in winelib. First thing is typelib registration, which doesn't work yet as the debug output tells. Okay, did that manually. Then, for setting the control's properties, I tried the easy way via IDispatch::Invoke(), which calls ITypeInfo::Invoke() and that's only a stub :( I worked around this via evil assembler hacks to call the interface's members as given by the vtable offsets in the FUNCDESC using stdcall convention - unfortunately g++ doesn't support specifying a calling convention for method pointers like HRESULT (IDispatch::*setProp)(BSTR). After getting this to work, I hit the next problem: unimplemented urlmon.RegisterBindStatusCallback and when I use a native urlmon.dll it tries to call shlwapi.154, with native shlwapi it still doesn't work somehow, but that's a different story. Anyway, what I'd basically need to get this to work properly is - typelib registration - IDispatch::Invoke() - RegisterBindStatusCallback() and probably asyncronous bind contexts - probably a "real" URL Moniker, not just CreateURLMoniker() using a File Moniker What I'd like to know is if anyone is already working on any of these and if so what's the status and how I could help getting these implemented. if no one started yet, I'd still like to give it a try. Thanks, -Malte PS: the attached patch fixes urlmon.h not being C++-safe. -- Wars don't determine who's right, only who's left.

WINE server messages
by David Howells 30 May '01

30 May '01

Hello Alexandre, I'm having a little trouble deciding exactly how to emulate the "module registration" functionality in my kernel module. It occurs to me that this might be easier to accomplish with a change to the current wine server message set. My idea is: * Have the server only deal with NT Section objects and views of Sections. * Have no separate module table attached to a process. * Implement NtQuerySectionInformation/NtSetSectionInformation calls (or whatever they're called) as wineserver messages. * Add an extra Wine-specific information class for the purpose of recording the extra module information. * The wineserver process structure can then be changed so that rather than keeping a separate list of process_dlls, they can just keep a list of section views, some of which will be images/modules.
