+ | Note that there is a separate Perlbrew environment for each architecture (32bit vs. 64bit machines) at ÚFAL, so if you switch to perl-5.18.2 on 32bit machines, you need to do it again on 64bit machines if you want to use perl-5.18.2 on both. | ||

+ | #cpanm -n Tk # Tk tests are long and pop up many windows | ||

+ | |||
+ | When compiled without XFT support, the fonts are ugly and some fonts (Cyrillic, Arabic,...) are completely unreadable. | ||
+ | First, you need some packages (which should be installed by default, so the following command is not needed) | ||
+ | |||
+ | sudo apt-get install libx11-dev libfreetype6-dev libxft-dev libpng-dev libz-dev | ||
+ | |||
+ | However, new Debian and Ubuntu (14.04) changed location of some files (freetype.h, | ||
