以下の手順に従って、Ubuntu Linux (Amazon EC2 インスタンス) で QT 4.7.0 ライブラリを構築しようとしています。
sudo apt-get update
sudo apt-get install build-essential
sudo apt-get build-dep qt4-qmake
sudo ./configure -openssl -release -no-webkit -nomake examples -nomake demos -nomake docs -v -prefix /usr/local/qt4 -opensource
sudo make sub-src
ビルドが失敗し、qpdf に関するエラーが発生します。
