Seriously, I'm not sure why you set that
variable. I never heard of
it before, and usually the safest way to get includes
added to the
compiler flags is via CXXFLAGS and CFLAGS.
I think he sets it because the Slackware official Qt3 build scripts we (I and Darrell) based ours on installs a profile script in /etc/profile.d that sets CPLUS_INCLUDE_PATH. I don't know why Slackware sets this variable but it has done it since at least 2003 and still does today (in the Qt4 package).
Yeah, what you said (as I just shared in a concurrent post. :) )
This raises some questions. Is the CPLUS_INCLUDE_PATH environment variable necessary at run for qt3 to behave? Or is this some kind of throw back to the early days of qt3 that has since become obsolete?
Not needed at runtime; it must be obsolete.
