Re: How to Calling PE Dlls on linux??
Hi, Damjan Jovanovic Thank you tired of the answer to my questions. I carefully read the wine part of the code and development document, searched in mail lists, these days. And I got some inspiration from wine plugin API wiki page and wine loader's code. I am considering of an approach. Link preloader and related resource(libwine) with my Linux native App. Do some modify with wine_init function, and call it before main(). This can be implemented by a global C++ objects's constructor. Upper two steps can deal with TEP and FS register. But I there may be another problem. If there was aready an static global C++ object in my App, How can I makde it initiatited after wine_init from in object. Do you have some other expostulate of this idea? BTW, I skim over mplayer and xine's parts of code. They don't dealwith TEB and FS register. They only do sth on LDT and allocat PE header before LoadeLibaray. Why they can run correctly??? 2007/8/22, Damjan Jovanovic [EMAIL PROTECTED]: On 8/21/07, trulyliu [EMAIL PROTECTED] wrote: 2007/8/21, Damjan Jovanovic [EMAIL PROTECTED]: On 8/21/07, trulyliu [EMAIL PROTECTED] wrote: 2007/8/21, Damjan Jovanovic [EMAIL PROTECTED]: On 8/21/07, trulyliu [EMAIL PROTECTED] wrote: Can I made Arithmetic.dll.so ?

Re: How to Calling PE Dlls on linux??
The issue of the order of global C++ object's constrution has been metioned in wine development guid section 8.3.3.Starting a Winelib process For the first scheme, how can we made win_init as the entry of .init section.

How to Calling PE Dlls on linux??
hi: I am sorry to disturb you with a question about calling PE Dll on linux. This is really an old question. I found the sameness issues in mail list. http://www.winehq.org/pipermail/wine-devel/2003-December/thread.html http://www.winehq.org/pipermail/wine-devel/2005-November/thread.html#41917 http://www.winehq.org/pipermail/wine-users/2004-August/014685.html http://www.winehq.org/pipermail/wine-devel/2006-August/050619.html I have tried the ways discussed in these threads。 But it's not clear enough how to do this. So I send this mail to you for some help. I have a PE Dll named Arithmetic.dll which exports a function, it's prototype is: void sort(unsigned int*, int num) I want to call the function in my Linux App. I used winedump to generate a spec file winedump spec Arithmetic.dll This comand generated three files: Arithmetic_dll.h Arithmetic_main.c and Arithmeticspec. What's the next exactly step I should do? What's the usage of the three files? And wow could I use them? I made reference to mplayer's implementation, It's code is a little clutter， and I don't have experience on MS D-Show. Could you give me some simple sample codes ?? Best Regards. -- [EMAIL PROTECTED]
Re: How to Calling PE Dlls on linux??
I have a PE Dll named Arithmetic.dll which exports a function, it's prototype is: void sort(unsigned int*, int num) The easiest way would be to use LoadLibrary/GetProcAddress to load the function from the library. That way you avoid linking to it which makes things more complicated. In order to be able to use wine functions you need to (re)compile parts of your program using Winelib (e.g. winegcc/wineg++). Your program will depend on Wine but you will be able to use the win32 dll. Regards, Roderick Colenbrander

I have a PE Dll named Arithmetic.dll which exports a function,
it's prototype is:
void sort(unsigned int*, int num)
I want to call the function in my Linux App.
You can't, it's not supported (yet), but what you want is the Wine
plugin API (http://wiki.winehq.org/WinePluginApi).
At the moment you have 2 options:
* Make a Windows application instead of a Linux application.
* Make a winelib application which will require wine to run but can
access Linux libraries as well (with some restrictions, eg. you have
to use Windows synchronization primitives instead of the pthreads
ones).
I used winedump to generate a spec file
winedump spec Arithmetic.dll
This comand generated three files: Arithmetic_dll.h Arithmetic_main.c and
Arithmeticspec.
What's the next exactly step I should do?
What's the usage of the three files?
And wow could I use them?
#include windows.h
int main(int argc, char **argv)
{
HANDLE h;
void (/*WINAPI?*/ *sort)(unsigned int,int);
unsigned int *nums = malloc(sizeof(unsigned int) * 4);
nums[0] = 3;
nums[1] = 2;
nums[2] = 1;
nums[3] = 0;
h = LoadLibrary(Arithmetic.dll);
sort = GetProcAddress(h, sort);
sort(nums, 4);
}
winegcc main.c -o main
./main
I made reference to mplayer's implementation,
It's code is a little clutter， and I don't have experience on MS D-Show.
Could you give me some simple sample codes ??
MPlayer's code is GPL, so if you use it your code will be GPL too.
