Using a windows dll from a winelib or possibly native linux app.
by Arthur Bergman Dec. 10, 2003

Dec. 10, 2003

Hi, I have been trying to develop an application using a vendor provided dll from an external vendor to work under linux. If we develop the app on a windows box and move it over to the wine environment it works, but it would be preferable to have a more native approach. So I tried using winelib and have progressed to a point where I have an application that compiles using the vendor supplied header files under gcc, and a vendor.dll.spec file that describes the DLL. However when I compile everything, the generated vendor.dll.so file does contain the correct symbols but they are undefined. Having played around using winemaker and winedump while trying to read up everything on winelib I am now stuck and not sure how to proceed forward. Thanks Arthur

This is all good, but: +typedef struct CCPRIVATE +{ + LPCHOOSECOLORW lpcc; /* points to public known data structure */ + int nextuserdef; /* next free place in user defined color array */ 1 (one) space indent?!? Please man, stick to 4-space indent, especially when the file was using 4 space indent. Such small indentation makes the code difficult to follow. I have to admit, my eyesight is not what it used to be... -- Dimi.

Hi Arthur, > the generated vendor.dll.so file does contain the correct > symbols but they are undefined. By any chance is the vendor dll implemented in C++? If not, this should work. If so, you have a bit of a problem, and one that no-one has seriously tried to overcome (or at least if they have, they haven't documented it). If the dll exports mangled names (_??xxx in the .spec file) then linking cannot occur when you build with gcc because gcc uses a different name mangling scheme. You would need to include stubs to call the real functions and export these with the gcc-mangled names, either by reimplementing the functions inside the dll, or calling through to the real dll with function pointers and GetProcAddress(). Are the vender dll/headers redistributable? Cheers, Jon __________________________________ Do you Yahoo!? New Yahoo! Photos - easier uploading and sharing. http://photos.yahoo.com/

rpcrt4 and rpcss with WINE and ReactOS
by Steven Edwards Dec. 10, 2003

Dec. 10, 2003

Hello, Ok I know this going to start YALD (Yet Another Long Discussion) that wont go anywhere right away but...... ReactOS is getting ready to do a major import of the WINE dlls as you guys know due to my repeated cross-postings to Wine-devel and ros-kernel. When we compile rpcrt and ole32 from WINE with some hacks we can make it work under ReactOS but I would like to develop a implementation that works properly without dirty hacking. I dont know much about WINEs rpcss other than whats in the comments of the code and for that matter I dont know much about Windows rpcss. Can we share these componates? How are we going to break compatiblity by doing this? Thanks Steven __________________________________ Do you Yahoo!? New Yahoo! Photos - easier uploading and sharing. http://photos.yahoo.com/

Adding support for a USB device
by Dan Timis Dec. 9, 2003

Dec. 9, 2003

Hi, I need help with supporting a particular USB device under wine. I have to start by saying that although I am an experienced C/C++ programmer with some Linux experience, I have almost no Windows or wine experience. The Windows code for which I need to provide support uses CreateFile() to get a handle to the device. The name of the device is something like "\\.\MyDevice0" "\\.\MyDevice1" and so on. Then, the code uses DeviceIoControl() to read and write from/to the device. The requirement is not to change the windows code. I looked through the wine code and I found this in device.c: static const struct VxDInfo VxDList[] I could add another entry into the table and write a deviceio handler (BOOL (*deviceio)(DWORD, LPVOID, DWORD, LPVOID, DWORD, LPDWORD, LPOVERLAPPED);). I wrote some test code in Linux using libusb reading and writing to the device so I know what to do inside the deviceio handler. Is this the right approach? If so, what do I need to do to get CreateFile to return the right handle? Or should I write an external driver that gets loaded by wine? If so, how would I do that? What are the chances that the Windows driver for this device would just work with wine? Thanks, Dan Timis Muse Research, Inc.

Hello I am really sorry for making multiple posts - I got the Rediffmail mailer's verification after 20 minutes (normally Yahoo!'s mailservers notify almost instantaneously..), but before I could realize it, my 4 messages had already been mailed out of the queue... This was the first time I was using an Indian mail server, and well as it turns out, it was slower than a USA server ?! Regards Subhobroto Sinha

Help for OLEAUT32 DLL problem
by Robert Iver Dec. 9, 2003

Dec. 9, 2003

Having a spot of trouble getting this function implemented in Wine so I can install a program for my job. It is basically a VB app that interfaces with a MySQL server database. I have heard that I cannot use a native DLL to do the job since it is OLE, so I have been trying to write a stub for it. Unfortunately, this is my first try at developing for Wine and I have writer's block. The function I am trying to implement is GetRecordInfoFromGuids. Could anyone out there write a basic stub for this program, so I can implement it and at least have an example to work with???? BTW, I have installed DCOM98, Crystal Reports and SQL Network Client Utility with no problems..
