Errata for BLFS Version 7.5

• There are several references throughout the book to $QTDIR. This reference should be $QT4DIR. Packages that are affected include Grantlee, Libdbusmenu-qt, Qca, Qjson, Polkit-Qt, Automoc4, Phonon, and Akonadi. The reference at the end of the page 'Starting KDE' should also be $QT4DIR.
• A few dependencies have been overlooked for OpenJDK. Attr and gtk+2 (instead of gtk+3) are required. And with the written instructions, nss is recommended.
• In the Xorg Fonts instructions "Install all of the packages by running...", the line "rm -rf $packagedir" may exit with error and stop the build, if not executed as root. One fix is to add "as_root" at the beginning of the line.
• In the Qt5 dependencies, ruby should be added as an optional dependency. It is required to build QtWebkit

Known Security Vulnerabilities

• Important. There is a critical security flaw in openssl versions 1.0.1 to 1.0.1f. Use the most current instructions for openssl in the BLFS development book. http://www.linuxfromscratch.org/blfs/view/svn/postlfs/openssl.html
