I am trying to write an x client application that will run on a windows xp machine. When I try to load any X related dll (in order to be able to call for example XOpenDisplay) the executable exits whith the message 5 [main] test3 2820 handle_exceptions: Exception: STATUS_ACCESS_VIOLATION 648 [main] test3 2820 open_stackdumpfile: Dumping stack trace to test3.exe.tackdump
This dump occurs when the system tries to load the library.
Why not link the library directly into the program? I'm not sure if LoadLibrary works well with cygwin dlls.
LoadLibrary usually works okay --- but it'd certainly be better, from a cygwin POV, to use cygwin1.dll's dlopen() instead. And there is sometimes a good reason to avoid direct linking: what if you want to "turn on" various windowing/GUI modes...e.g. rxvt on cygwin can currently be used without an Xserver running, without even having the X libs installed. If $DISPLAY is :0, it never tries to load the X stuff, but simply uses Windows GDI. If the Xlibs were linked directly into the app, you'd always have to have the Xlibs installed, even if you didn't want to ever use rxvt in "X11" mode.
