Build issue while packaging docker for openSUSE

[Flavio Castelli]

Hello, I'm the docker's maintainer for openSUSE. While upgrading to 0.7.0 I decided to fix the build process used at packaging time (in the past I didn't use hack/make.sh binary, shame on me :).

I'm building docker using the intree dependencies shipped inside of 'vendor'. The build process takes place on a x86_64 machine which has go 1.2rc2 installed.

This is the output produced during build time (I've added "set -x" to make.sh to have more debugging information):

As you can see the build fails because there are "no buildable Go source files in /home/abuild/rpmbuild/BUILD/docker/vendor/src/code.google.com/p/gosqlite/sqlite3". This directory contains the 'driver.go' file, which looks perfectly fine to me.

Do you know what is going wrong?

Thanks in advance
Flavio

I managed to fix the issue by building a dynbinary via make.sh.

That's nice, but I'm still interested in knowing what is going wrong
with the static binary build. Ping me if you have any idea :)

Cheers

Hi Flavio!  Thanks for switching to using our build script - we really appreciate that.  As you've discovered, the "dynbinary" bundlescript was created specifically for packagers, since getting the completely-static monolithic binary to compile correctly in a normal "packaging" environment can be quite a challenge (even in places like Gentoo)!

If I had to guess what was wrong with your static build before, I would guess that you didn't have a static copy of libsqlite3.  You'd also need a static copy of libdevmapper (which is more difficult to come by reasonably than sqlite3 is).
