    Did you cross-compile or already have all dependencies for poppler ? If you don't have Qt for ARM, it won't build it

          Are you sure that the build system finds your arm Qt ?

          If you download pre-built package, you also have to download their dependencies

                It means a package has been linked to a pretty old version of glibc. Are you sure you downloaded the latest version of the armel libraries ?

                    They should be same since they are built at the same time

                        Seems there's something wrong in your dependencies. Check that you download all packages from the same distribution

                            Don't know this one, generally if I need to download precompiled package I go for the debian armel architecture.

                                      There can be several things:
