PLplot Wiki

Description

FreeType 2 is a software font engine that is designed to be small, efficient, highly customizable, and portable while capable of producing high-quality output (glyph images). It can be used in graphics libraries, display servers, font conversion tools, text image generation tools, and many other products as well. http://www.freetype.org reveals more information.

Instructions for Mac OS X

PLplot uses either fonts provided by the Free UCS Outline Fonts project (http://savannah.gnu.org/projects/freefont/) or Windows fonts (Arial, etc.). Both are not installed on Mac OS X by default. You can download the FreeFonts from http://download.savannah.gnu.org/releases/freefont/ and copy the ttf files into the User's Library/Fonts directory. In order cmake can find these fonts, we need to set the PL_FREETYPE_FONT_PATH option, e.g.

cmake -DPL_FREETYPE_FONT_PATH=/Users/smekal/Library/Fonts/ ..

Macports

freetype is also available via Macports. To install the freetype library open the terminal and enter

sudo port install freetype

Instructions for Windows

• Download the Freetype library
• Unzip the ft237.zip package in a suitable place
• Cd into the new directory

MinGW compiler

• Then for MinGW (call mingw32.make twice!):

mingw32-make
mingw32-make
copy objs\freetype.a objs\libfreetype.a

Visual C++ compiler

• Or for Visual C++ (you need to use GNU-Make not nmake - download it from http://prdownloads.sf.net/mingw/mingw32-make-3.80.0-3.tar.gz?download or http://gnuwin32.sourceforge.net/packages/make.htm):

path_to_gnu_make\mingw32-make setup visualc
path_to_gnu_make\mingw32-make

• For Visual C++ 2005 you need to change line 69 of freetype-2.2.1\builds\compiler\visualc.mk to

CFLAGS ?= /nologo /c /Ox /W3 /WX /D_CRT_SECURE_NO_DEPRECATE

Set CMake paths

• set environment variables (for MinGW and Visual C++)

set FREETYPEDIR=C:\freetype-2.2.1
set CMAKE_INCLUDE_PATH=%FREETYPEDIR%\include
set CMAKE_LIBRARY_PATH=%FREETYPEDIR%\objs

CMake is now able to find the freetype library and headers.
