In the configure script, I have to replace all "-lc" by "-lc_r".
BTW config/gnome.m4 and config/ltmain.sh do already something is this direction,
but this is obviously not enough! ltmain.sh says somewhere:
*-*-openbsd*)
# Do not include libc due to us having libc/libc_r.
[...]
In addition I have to set the following environment variables, before running
configure:
CFLAGS=-D_THREAD_SAFE -pthread
CPPFLAGS=-D_THREAD_SAFE -pthread
CXXFLAGS=-D_THREAD_SAFE -pthread
Then everything is fine.
HOORAY: LyX runs wonderfully with Qt3 on my FreeBSD box!!! Nice, nice, nice!
Apparently, if LyX must work "out-of-the-box" with Qt, then (Free)BSD requires
some more tweeking of the scripts.
