Hello Angus,
I can't find the file "exdll.h" in CVS, where is it?
C:\Program Files\NSIS\Contrib\ExDLL\exdll.h
I just compiled your latest lyx_configure.C and got two warnings that
things defined in the exdll.h (a one from Juli 2005) aren't used. So no
real problem but perhaps you have a more actual one.
I think that this is something that was fixed in more recent versions of
NSIS, but here's mine anyway.
Btw. what are the changes in the lyx_configure.C from today are for?
They make it more robust. I've used it for the last several LyX1.3.7preX
releases.
thanks and best regards
Uwe
Happy New Year!
Angus
