I might do code obfuscation. But, it may be safer for me to do something like: #define MyClass F18Rsjkfgwe6 #define MyMethod aYSm48dYo49H class MyClass { void MyMethod(cha *, bool); etc. rather than mess with the binaries. Dan

Winelib and MFC and mixing native Windows DLLs
by Raghavan Gurumurthy 13 May '04

13 May '04

I am trying to build my MFC-based Windows application on Linux. First question - I read in the Winelib user guide that I have to build MFC completely on Winelib as well. Is this really a must? Is there no other alternative? Second question - If my Windows application uses 10 DLLs, do I have to build all these 10 DLLs in addition to the executable on Winelib? Or can I leave the 10 DLLs run in 'native' mode and only convert the executable to be built with Winelib? Thanks in advance, Raghavan

Winelib Native Linux App
by Simon Craythorn 13 May '04

13 May '04

I'm a little confused on two points. I wrote a simple windows application just to open a window. It has a file menu with exit on it, and that's about it. All the documentation I read for Winelib suggests that re-compiling the application is the best option as this will give a native linux app that can be run directly. But when I compile this app with winelib it generates "winer.exe.so" which needs to be started with the command "wine winer.exe.so". This isn't my idea of being able to be run directly. Secondly, all my windows apps and DLL's are in Borland Builder (just native Win32 C, no VCL/MFC or other third party products). I have Kylix3 installed. I've managed to re-compile my test app with Kylix and link it to the Wine libraries. When I try and run the resulting executable it complains that it can't fine kernel32.dll.so. Just to test I tried copying kernel32.dll.so to the same place as my test app, same result. I added /usr/lib/wine to ld.so.conf and ran ldconfig, but this doesn't help either. Anyone any ideas on either of these issues. Searching the lists it seems I'm the only one to attempt compiling with Kylix at all. -- Simon Craythorn using MailCopa V6.01 InterVations, Inc http://www.intervations.com http://www.mailcopa.com

[patch] Listview drag-and-drop fix
by Paul Rupe 13 May '04

13 May '04

Xnews was treating all mouseclicks as drag-and-drop operations in the newsgroup listview. The problem was that LISTVIEW_TrackMouse was losing the WM_LBUTTONUP message. This patch adds the missing call to DispatchMessage.

Exporting symbols
by Dan Timis 13 May '04

13 May '04

Hi, We need to have a library that links statically to a wine application. The wine application is an .exe.so, so everything becomes in the end an exe.so. The problem we have is that all the symbols are exposed. I have very little experience with Windows, but I understand that with a Windows DLL you can export certain functions, while hiding the others. I know that's also true for the Mac. Is there any way to export only the functions that are called by the code we link to, without exposing the internal workings? Ideally we would like to be able to provide a static library created with ar or ranlib, link that library with other object files to create a .exe.so for wine, but when you do "nm" on the resulting .exe.so you would not see all the inner workings of our library. Is that possible? Thanks, Dan Timis Muse Research, Inc.

Clipboard functionality across processes
by Santosh Siddheshwar 12 May '04

12 May '04

Hi, Does WINE support access to clipboard data across WINE processes. For e.g. one app opens the clipboard and sets data into it using SetClipboardData, closes it and then exits. The other app tries to retrieve this data. It works in windows but doesnt seem to do so in WINE.

probs w/ make and make install

cd `dirname dlls/__install-lib__` && make install-lib rm -f libdxerr8.a && ln -s dxerr8/libdxerr8.a libdxerr8.a rm -f libdxerr9.a && ln -s dxerr9/libdxerr9.a libdxerr9.a rm -f libdxguid.a && ln -s dxguid/libdxguid.a libdxguid.a rm -f libuuid.a && ln -s uuid/libuuid.a libuuid.a cd `dirname advapi32/__install__` && make install ../../tools/mkinstalldirs -m 755 /usr/local/lib/wine /usr/bin/install -c advapi32.dll.so /usr/local/lib/wine/advapi32.dll.so cd `dirname amstream/__install__` && make install ../../tools/mkinstalldirs -m 755 /usr/local/lib/wine /usr/bin/install -c amstream.dll.so /usr/local/lib/wine/amstream.dll.so cd `dirname avicap32/__install__` && make install ../../tools/mkinstalldirs -m 755 /usr/local/lib/wine /usr/bin/install -c avicap32.dll.so /usr/local/lib/wine/avicap32.dll.so cd `dirname avifil32/__install__` && make install ../../tools/mkinstalldirs -m 755 /usr/local/lib/wine /usr/bin/install -c avifil32.dll.so /usr/local/lib/wine/avifil32.dll.so make: don't know how to make _install_/avifile.dll.so. Stop *** Error code 2 Stop in /usr/home/vertigo/wine-20040505/dlls. *** Error code 1 Stop in /usr/home/vertigo/wine-20040505. ----------------------------- this is the 2nd stop that occured... during make, towards the end, it couldn't open /home/vertigo/wine-20040505/programs/winetest/advapi32_test.exe... i checked in that dir, and the files were still *_test.exe.so. seemingly, the previous step that copied these files here also stripped them, but did not change their names (remove the .so). i did this manually, and retried make, which finished. the above stop happens almost immediatly from make install. this is on freebsd4.9, and this is basically the same that has always happened for me with all versions of wine i've tried. can someone either help me get this to work, or atleast stop the spreading of the lie that wine works on bsd (have never heard someone say that they had it running on bsd). i've been kicking this horse for months, is it dead? -shaun
