Msi.dll was Re: working together on stdole.tlb and a end to dcom9x

by James Tabor

Wow! To complete the port for msi.dll, I need LoadTypeLib, RegisterTypeLib and ITypeLib_Release. So, is stdole32 a "32 bit" replacement for Wine typelib oleaut32 functions? I see only CreateTypeLib2 in the file. Thanks, James ps. I can compile msi w/o those functions, ha! just comment them out. So here is a patch and makefiles, just remove the "msi-" and go.

compile failure on debian with mingw32msvc

by Damian Dimmich

Hi, Just like to let you know that the latest cvs code does not compile out of the box using mingw on a debian testing box. $i586-mingw32msvc-cc --version i586-mingw32msvc-cc (GCC) 3.4.2 (mingw-special) The problem is some functions are re-declared in the string.h (line 169, wchar_t() ) and stdio.h (line 269, putwc() )files. Also the loadlib.c test file failed to compile since it was not including stdlib.h and could not find the mbstowcs function. This is the latest cvs code from 5:30'ish GMT. Cheers, Damian output from cvs diff: Index: apps/testsets/loadlib/loadlib.c =================================================================== RCS file: /CVS/ReactOS/reactos/apps/testsets/loadlib/loadlib.c,v retrieving revision 1.2 diff -r1.2 loadlib.c 26a27 > #include <stdlib.h> Index: include/msvcrt/stdio.h =================================================================== RCS file: /CVS/ReactOS/reactos/include/msvcrt/stdio.h,v retrieving revision 1.8 diff -r1.8 stdio.h 269c269 < int putwc(wint_t wc, FILE* fileWrite); --- > //int putwc(wint_t wc, FILE* fileWrite); Index: include/msvcrt/string.h =================================================================== RCS file: /CVS/ReactOS/reactos/include/msvcrt/string.h,v retrieving revision 1.6 diff -r1.6 string.h 169c169 < wchar_t* wcsdup(const wchar_t* wsToDuplicate); --- > //wchar_t* wcsdup(const wchar_t* wsToDuplicate);

ELF mapping support for ntoskrnl, for anybody who is interested (untested)

by Gregor Anich

Hi! I have attached a elf.h file (to be put into the toplevel include directory) with ELF structures/constants and a patch for ntoskrnl/mm/section.c which should add support for mapping ELF files with NtCreateSection. It is completly untested I think. We also have to port a runtime linker (rtld) - it has to be statically linked/use only syscalls because if an ELF file contains an interpreter name (on linux something like /lib/rtld-elf.so) the kernel usually maps the interpreter instead (or additionally) and begins execution at the interpreter's entry point, passing it a file handle or the base address of the file to be linked & ran and the interpreter does the rest. - blight #ifndef __INCLUDE_ELF_H #define __INCLUDE_ELF_H #ifdef __64BITS__ /* FIXME: how to check for 64 bits? */ # define ELF_ARCH_SIZE 64 #else # define ELF_ARCH_SIZE 32 #endif /* 32-bit data types */ typedef unsigned long ELF32_ADDR; /* Unsigned program address */ typedef unsigned short ELF32_HALF; /* Unsigned medium integer */ typedef unsigned long ELF32_OFF; /* Unsigned file offset */ typedef unsigned long ELF32_SWORD; /* Signed large integer */ typedef unsigned long ELF32_WORD; /* Unsigned large integer */ typedef ELF32_OFF ELF32_HASHELT; /* Hash element? */ /* Elf data encodings */ #define IMAGE_ELF_DATA_NONE 0 /* Invalid data encoding */ #define IMAGE_ELF_DATA_2LSB 1 /* 2's complement, LSB first */ #define IMAGE_ELF_DATA_2MSB 2 /* 2's complement, MSB first */ /* Elf object file types */ #define IMAGE_ELF_TYPE_NONE 0 /* No file type */ #define IMAGE_ELF_TYPE_REL 1 /* Relocatable file */ #define IMAGE_ELF_TYPE_EXEC 2 /* Executable file */ #define IMAGE_ELF_TYPE_DYN 3 /* Shared object file */ #define IMAGE_ELF_TYPE_CORE 4 /* Core file */ /* Elf machines */ #define IMAGE_ELF_MACHINE_NONE 0 /* No machine */ #define IMAGE_ELF_MACHINE_M32 1 /* AT&T WE 32100 */ #define IMAGE_ELF_MACHINE_SPARC 2 /* SPARC */ #define IMAGE_ELF_MACHINE_386 3 /* Intel 80386 */ #define IMAGE_ELF_MACHINE_68K 4 /* Motorola 68000 */ #define IMAGE_ELF_MACHINE_88K 5 /* Motorola 88000 */ /* 6 is reserved */ #define IMAGE_ELF_MACHINE_860 7 /* Intel 80860 */ #define IMAGE_ELF_MACHINE_MIPS 8 /* MIPS RS3000 (MIPS I) */ #define IMAGE_ELF_MACHINE_S370 9 /* IBM System/370 Processor */ #define IMAGE_ELF_MACHINE_MIPS_RS3_LE 10 /* MIPS RS3000 Little-endian */ /* 11-14 are reserved */ #define IMAGE_ELF_MACHINE_PARISC 15 /* Hewlett-Packard PA-RISC */ /* 16 is reserved */ #define IMAGE_ELF_MACHINE_VPP500 17 /* Fujitsu VPP500 */ #define IMAGE_ELF_MACHINE_SPARC32PLUS 18 /* Enhanced instruction set SPARC */ #define IMAGE_ELF_MACHINE_960 19 /* Intel 80960 */ #define IMAGE_ELF_MACHINE_PPC 20 /* PowerPC */ #define IMAGE_ELF_MACHINE_PPC64 21 /* 64-bit PowerPC */ /* 22-35 are reserved */ #define IMAGE_ELF_MACHINE_V800 36 /* NEC V800 */ #define IMAGE_ELF_MACHINE_FR20 37 /* Fujitsu FR20 */ #define IMAGE_ELF_MACHINE_RH32 38 /* TRW RH-32 */ #define IMAGE_ELF_MACHINE_RCE 39 /* Motorola RCE */ #define IMAGE_ELF_MACHINE_ARM 40 /* Advanced RISC Machines ARM */ #define IMAGE_ELF_MACHINE_ALPHA 41 /* Digital Alpha */ #define IMAGE_ELF_MACHINE_SH 42 /* Hitachi SH */ #define IMAGE_ELF_MACHINE_SPARCV9 43 /* SPARC Version 9 */ #define IMAGE_ELF_MACHINE_TRICORE 44 /* Siemens Tricore embedded processor */ #define IMAGE_ELF_MACHINE_ARC 45 /* Argonaut RISC Core, Argonaut Technologies Inc. */ #define IMAGE_ELF_MACHINE_H8_300 46 /* Hitachi H8/300 */ #define IMAGE_ELF_MACHINE_H8_300H 47 /* Hitachi H8/300H */ #define IMAGE_ELF_MACHINE_H8S 48 /* Hitachi H8S */ #define IMAGE_ELF_MACHINE_H8_500 49 /* Hitachi H8/500 */ #define IMAGE_ELF_MACHINE_IA_64 50 /* Intel IA-64 processor architecture */ #define IMAGE_ELF_MACHINE_MIPS_X 51 /* Stanford MIPS-X */ #define IMAGE_ELF_MACHINE_COLDFIRE 52 /* Motorola ColdFire */ #define IMAGE_ELF_MACHINE_68HC12 53 /* Motorola M68HC12 */ #define IMAGE_ELF_MACHINE_MMA 54 /* Fujitsu MMA Multimedia Accelerator */ #define IMAGE_ELF_MACHINE_PCP 55 /* Siemens PCP */ #define IMAGE_ELF_MACHINE_NCPU 56 /* Sony nCPU embedded RISC processor */ #define IMAGE_ELF_MACHINE_NDR1 57 /* Denso NDR1 microprocessor */ #define IMAGE_ELF_MACHINE_STARCORE 58 /* Motorola Star*Core processor */ #define IMAGE_ELF_MACHINE_ME16 59 /* Toyota ME16 processor */ #define IMAGE_ELF_MACHINE_ST100 60 /* STMicroelectronics ST100 processor */ #define IMAGE_ELF_MACHINE_TINYJ 61 /* Advanced Logic Corp.

Web site actualization

by Lucio Diaz

Could Someone with autorization to edit the Reactos.com Web page look at my FAQ and Howto, to decide if he/she likes it and what have to be changed so it could be in the web page. I think it is a improvement over the actual texts. The texts i did are thought for everybody, even with screenshots to guide the people with little experience. Thankyou, Lucio Diaz. ______________________________________________ Renovamos el Correo Yahoo!: ¡100 MB GRATIS! Nuevos servicios, más seguridad http://correo.yahoo.es

GMT

It seems a pain in the @ss to code the whole thing, taking in acount ALL the countries and their probable timezones(countries with diferent timezone areas) for something as easy to the user as to look at his watch and set the time. I dont mind what standard (if GMT -8 or GMT 0) you chose, but i believe that making it more elaborate does not worth today when many other things, quite more important, are waiting to be implemented (like Networking). I am sure that time will come for those details. ______________________________________________ Renovamos el Correo Yahoo!: ¡100 MB GRATIS! Nuevos servicios, más seguridad http://correo.yahoo.es

Moving ntoskrnl configuration defines into ntoskrnl/include/config.h ?

by Gregor Anich

Hi! I have written a tool to configure the ReactOS source tree (customize the build) It builds a GUI interface from an XML file which lists all the possible options and how they are "realized" (in which file a value has to be changed to make the build-system do what is wanted, i.e. set KDBG in config to 1) I would like to add the possibility of configuring things like WHOLE_PAGE_ALLOCATIONS or TAG_STATISTICS_TRACKING (from ntoskrnl/mm/npool.c) It would be good if such defines were moved into a file like ntoskrnl/include/config.h which is then included by ntoskrnl.h and looks like this: /* Enable tracking of statistics about the tagged blocks in the pool */ #undef TAG_STATISTICS_TRACKING /* * Put each block in its own range of pages and position the block at the * end of the range so any accesses beyond the end of block are to invalid * memory locations. */ #undef WHOLE_PAGE_ALLOCATIONS I don't want to make the tool edit the C files directly. If anybody is against this please let me know, otherwise I will do it. (Note: The tool is written in python and will thus not be allowed into the reactos tree but I will provide it for whomever is interested) Thanks, blight
