I'm attempting to cross compile a couple Ubuntu Precise Packages, My current arch is amd64 my target is armhf. I have the correct cross compile GCC toolchain installed, I have correctly utilized the toolchain to previously compile the kernel.

I was wondering about the package build dependencies, does the build just get its includes from my regular dev packages? Do I need to do anything special?

I execute this command, this time adding the arch

dpkg-buildpackage -rfakeroot -aarmhf

near the end of the build, I get this

... File format not recognized
make: *** [binary] Error 29
dpkg-buildpackage: error: fakeroot debian/rules binary gave error exit status 2

The posted log snippet is too short to see the cause of the issue. It would also help to be able to see the source package in question. – tumbleweed Jun 3 '12 at 2:04

The easiest way to cross-build packages is to not cross build them, but use an entire emulated armhf chroot. Use pbuilder-dist or mk-sbuild to create an armhf chroot, and just build the packages in it.

This is a solution non grata. I've obviously chosen to cross-compile, which is known to be more difficult. If I wanted to chroot, I would have already chosen to, it's not like the internet isn't practically drowning in chroot documentation. Actually I digress, I asked a more general Debian question... This might not even be the place to do such. – TechZilla May 31 '12 at 17:34
I also would want to say, I've read some packages won't cross-compile. In such a case, this type of error is common. – TechZilla May 31 '12 at 17:35
Do you have qemu-user-static installed? – tumbleweed May 31 '12 at 23:55
yes, I even already have a chroot set up. I was just hoping I could get away from it, and get the benefits of cross-compiling. – TechZilla Jun 1 '12 at 5:14
