I've tried to use expat with digital mars compiler, but it seems not to recognise the libraries. I've used the implib utility. The command line looks like this: dmc -L/libexpat main.cpp The code compiles well, but when i try to link it, i have the following messages: link main,,,user32+kernel32/noi/libexpat; OPTLINK (R) for Win32 Release 7.50B1 Copyright (C) Digital Mars 1989 - 2001 All Rights Reserved OPTLINK : Warning 9: Unknown Option : LIBEXPAT main.obj(main) Error 42: Symbol Undefined _XML_ParserFree main.obj(main) Error 42: Symbol Undefined _XML_GetCurrentLineNumber main.obj(main) Error 42: Symbol Undefined _XML_ErrorString main.obj(main) Error 42: Symbol Undefined _XML_GetErrorCode main.obj(main) Error 42: Symbol Undefined _XML_Parse main.obj(main) Error 42: Symbol Undefined _XML_SetCharacterDataHandler main.obj(main) Error 42: Symbol Undefined _XML_SetElementHandler main.obj(main) Error 42: Symbol Undefined _XML_SetUserData main.obj(main) Error 42: Symbol Undefined _XML_ParserCreate --- errorlevel 9 Any ideea?

Thanks for your fast reply. Unfortunatelly I have to build a console aplication, so I would rather not include wx in my program. The fact is that I'm quite new to c++ and I don't know very much about linking and other stuff. This solution was allready built (also by me) using mingw, but I would like to use digital mars because of its qualities. Thanks anyway In article <c7tdqq$1los$1 digitaldaemon.com>, W這dzimierz Skiba says...adi <adi_member pathlink.com> wrote in news:c7t8ec$1do6$1 digitaldaemon.com:I've tried to use expat with digital mars compiler, but it seems not to recognise the libraries.

But since you probably have wrong idea of what wxWidgets is, I have to correct you that you can succesfully build console programs with it. wxWidgets is toolkit builded from a few libraries. wxBase and wxNet are supposed to fine work in consoles and there is wxAppConsole class for such purposes.

Try putting the library after main.cpp: dmc main.cpp libexpat.lib You cannot fail if you assume that a linker (including the GNU and Linux and FreeBSD linkers) resolves unknown symbols in one pass: it resolves unknown symbols from each file it processes from left to right on the command line. adi wrote:I've tried to use expat with digital mars compiler, but it seems not to recognise the libraries.

Thanks again for the fast reply, It does not work this way. I've tried it. I have the same error message. I've tried it even with the linker.

The dm linker works with OMF files, not COFF files. There is a utility to convert from COFF libraries to OMF libraries, coff2omf.exe. www.digitalmars.com/ctg/coff2omf.html Also, scooter is correct in how to specify a library file to dmc.

Thank you all a lot. After converting the lib with coff2omf the executable file is generated. Unfortunatelly the program crashes when I try to parse the file. The one compiled with mingw works well with the same code. I will try and work on it some more. Thank you all Adi.

I have another question is it possible to use lib files made with another compiler with digital mars or not. It seems that it is not.Your main problem, if it's not the library format, is the "-L/libexpat". If you take a look at the DMC compiler's options page (http://www.digitalmars.com/ctg/sc.html), you'll immediately notice that "-L/" is used to specify options for the linker. This means that "-L/libexpat" isn't an option OPTLINK understands. :-)

Just recompile the expat code into a .LIB and include that .LIB in your link command. I have used expat with DMC for years!

Perhaps this is the next step I will try as the executable file still crashes when I try to parse the file (the odd thing is that it creates the parser without problems).

If you compile some code with debug turned on, a compiler might initialize all variables to 0. If the optimizer is turned on, that initialization doesn't happen. Suddenly your code doesn't work. Yes, it's the library's fault, not yours. But the problem doesn't show up until you run the program due to variations in how a compiler works. In Win32, there are also variations in calling convetions, another thing to consider. DMC, in my experience, has found bugs in my code far better than GCC. But I don't work solely under Win32. The moral of the story: use different compilers to make your code more robust. :-) -scooter

The Linux VM may have improved to the point that the two OSes have achieved parity, the "O(1)" scheduler may also have improved things for Linux as well.
