Build it on an ARM box, as Debian packages (in general) need to build on native hardware. > > I also want to mention that I already tried several ways (cross-compile > and qemu): > > 1. cross-compile: > I have installed the emdebian toolchain by doing: > > aptitude install emdebian-archive-keyring > echo "deb http://www.emdebian.org/debian/ squeeze main" >> > /etc/apt/sources.list > aptitude update > aptitude install gcc-4.4-arm-linux-gnueabi cpp-4.4-arm-linux-gnueabi > > Then I did: > apt-get source libqt4-dev > dpkg-buildpackage -aarmel -j4 > > The build-process started but died after 3 minutes with messages like > this: > > animation/qsequentialanimationgroup.cpp:467: warning: unused variable ‘q’ > ../../include/QtCore/../../src/corelib/arch/qatomic_arm.h: Assembler > messages: > ../../include/QtCore/../../src/corelib/arch/qatomic_arm.h:131: Error: no > such instruction: `swpb %al,%bpl,[%rbx]' > ../../include/QtCore/../../src/corelib/arch/qatomic_arm.h:131: Error: no > such instruction: `swpb %al,%bpl,[%rbx]' > > 2. qemu: takes forever and only one Host-CPU is used. QEMU runs at an equivalent of about 1/12th of the host CPU frequency, so a 2400MHz 386 emulates at about the speed of a 200MHz ARM CPU. > I'm still searching for a practicable way of rebuilding bigger debian > packages. There's a 500MHz 512MB Debian armel box here that you can use over SSH - write privately if that would be useful. Not that it won't still take forever... (where forever is defined as any time period longer than an hour :) For greater speed, you can buy/borrow/use something like a sheevaplug or whatever the cheap top-end ARM gadget is these days.
