RE: Re: Development Environment Problems

I won a fight with the source distros the other day. Previously I had
used the binary rpms without any problem, but I wanted to build an app
based upon an existing app source and thus pulled down the qtopia
source. Initially I wasted a lot of time on qpe.sourceforge/net because
many comments point there. This seems to be out of date and no longer
maintained. Unfortunately there is no comment stating this anywhere
(Kent, is this SF site no longer used? If so can someone add a comment
to let people know where to go now).

After giving up on the 2.4 distro from SF I eventually found the 2.5
distro on the trolltech site (though I don't find the TT site to be the
easiest site to navigate through. I built this and set my QTDIR to my
local source QT232 build dir and QPEDIR to my local source QPE build.
This was fine and works perfectly for the x86 builds. To build for the
Z, I continued to use the binary distro libs in /opt/Qtopia/sharp (for
both QTDIR and QPEDIR) this also works fine.

One other pointer from my battle....

I made a copy of the source of embedded console (which I wanted to
modify) outside of the QPE tree. I ran tmake on it and built, the result
was a binary that SEGV'd in the qpeapplication constructor!! It wasn't
until I moved my modified source back inside the QPE tree and
constructed the Makefile using ./configure <myprojectsubdir> that I got
a valid Makefile that did not core. This is not documented anywhere that
I can find.
