Re: [Ltib] Problems building Qtopia-2.2.0 on Ubuntu x64

[Stuart Hughes]

Hi Peter,

I think in this case qtopia is incorrectly trying to link to the host 
(build machine) libraries.  However for the record, if you're running on 
an Ubuntu (Debian) 64bit distro then you do need to make sure you have 
some 32bit libraries, these are required for the toolchains we have 
which are built on 32bit machines.  The names on Ubuntu/Debian IIRC are:
        * ia32libs
        * lib32stdc++ (not sure if this is needed?)

The fact you can build this far tells me you probably already have these 
installed.

A while back when I had access to a 64bit Fedora machine I did try 
fixing the build for qtopia-2.  I got some of the way and have just 
checked in an update to the spec file to Savannah CVS.  This does some 
build time changes and references a new patch (so you'll need to remove 
your current rpm/BUILD/qtopia* or manually apply 
qtopia-free-2.2.0-64bithost.patch).

While this fixes some of the issues, I didn't get to finish this (I got 
vectored off).  Hopefully with this and maybe some more digging on your 
side you can get it fixed.  I don't have a 64bit host, but I'll try to 
help if you run into problems.

Regards, Stuart
