Unloading implicitly loaded DLLs
by Michael Ost 04 Jan '06

04 Jan '06

I am looking for some expert advice in how to handle unloading "implicitly loaded DLLs". I have found two issues. (1) The first is a crash that happens in dlls/ntdll/loader.c MODULE_FlushModrefs. wine_unload_dll() is called for such a DLL, but SectionHandle is NULL so the call crashes. My solution was to turn off the LDR_WINE_INTERNAL flag in attach_implicitly_loaded_dlls() but I am not real clear what that flag is or whether that approach is good. An alternative is to add a check for a null SectionHeader before calling wine_unload_dll(). (2) Second is that these DLLs are DLL_PROCESS_DETACHED in process_detach() every time _any_ DLL is unloaded. This happens because the LoadCount is 0. I set it to -1 in attach_implicitly_loaded_dlls() which does the trick. But again I don't know what the heck I am messing with. Is that OK? Attached is a diff of the two changes. I'm not looking for points for style. But just a check on the approach for now. Thanks ... mo

I don't know about AIX; somebody from CA asked about it last year. But there are a few folks using Winelib with alternate OS's and CPUs. Perhaps some of them would be able to help you past some of the rough spots. A few links from a quick google search: Robert Lunnon got a Solaris/X86 port working; see http://members.optusnet.com.au/bobl/ http://www.blastwave.org/wine/ http://wiki.jswindle.com/index.php/Installing_Wine#Solaris And various people are using Winelib on Solaris/Sparc; see http://www.winehq.org/?issue=302#Building%20Wine%20on%20Sparcs And then there are the folks building Wine for Darwin. http://darwine.opendarwin.org Good luck, and do keep us posted! I bet you're not the only one who wants this. - Dan -- Wine for Windows ISVs: http://kegel.com/wine/isv

run jboss with a mde file as source
by Curro Amores 03 Jan '06

03 Jan '06

hi: i want to run jboss in linux and connect to an Ms Access odbc source. I think it doesnt exist odbc driver for Access in Linux. I Have read something about ODBC-ODBC but i think it is for accessing a mde file in a windows machine from linux. I have created the bridge with ODBC in wine (using the control pane with winetools) Then i have tried to run jboss windows version (run.bat) with wcmd but i got a message that run.jar file cant not be found. Do i have to install java windows version with wine? I have tried as well but the installation crashes Any idea? thanks
