Re: Development Environment Problems

Thanks for the replies.  I would have installed the Qtopia 1.5.0 binary 
rpm, but I had read on this list that several people have had problems 
with it.  It also requires glibc 2.2, and my linux box is still running 
Redhat 6.1.  I tried to upgrade glibc, but that has many dependencies 
(that have many other dependencies), and it would have taken far too 
much time.  Perhaps it's time that I get Redhat 7.  

Instead, I used the Qtopia 1.5.0 source rpm from the Trolltech site.  I 
compiled Qt-Embedded 2.3.2 with Qt 2.3.2, and then I compiled Qtopia 
1.5.0 with Qt-Embedded 2.3.2.  Then I repeated this process with the 
cross-compiler to get the Zaurus libraries.  Is this the correct method 
for compiling Qtopia from sources?  If so, why I am I getting my strange 
compile errors?

Thanks again for your help,
James Bernsen
