When I first built the X11R6.3 on my Win95 box I could not get the
DDLs (libX11.dll, etc.) to build correctly. The actual compilation
would go fine without a glitch, but I could not run any client. So, I
turned to Sergey who was able to determine that
- X11R6.3 DLLs build on Win95 does not work
- X11R6.3 DLLs build on WinNT works on both win95 and winNT
What I have in my distribution is a mixed of things: *.a built on
win95 together with the *.dll's I got from Sergey. (At the time I did
not have access to a NT box). If I recall well, the problem was
related to a ld bug. Sergey, do you confirm this?
Arlindo.
