如何将 freetype2.6 库添加到 code::blocks
How to add the freetype2.6 library to code::blocks
我对代码块还很陌生，但我在尝试解决这个问题时学到了很多东西。不幸的是我还没有完全弄明白。我需要将 Podofo-0.9.3 添加到我的代码块编译器中，但先决条件是 freetype2.6。我阅读了freetype的安装文件：
Instructions on how to build FreeType with your own build tool
==============================================================
See the file `CUSTOMIZE' to learn how to customize FreeType to
specific environments.
I. Standard procedure
---------------------
* DISABLE PRE-COMPILED HEADERS! This is very important for Visual
C++, because FreeType uses lines like:
#include FT_FREETYPE_H
which are not correctly supported by this compiler while being ISO
C compliant!
* You need to add the directories `freetype2/include' to your
include path when compiling the library.
* FreeType 2 is made of several components; each of them is located
in a subdirectory of `freetype2/src'. For example,
`freetype2/src/truetype/' contains the TrueType font driver.
* DO NOT COMPILE ALL C FILES! Rather, compile the following ones.
-- base components (required)
src/base/ftsystem.c
src/base/ftinit.c
src/base/ftdebug.c
src/base/ftbase.c
src/base/ftbbox.c -- recommended, see <ftbbox.h>
src/base/ftglyph.c -- recommended, see <ftglyph.h>
src/base/ftbdf.c -- optional, see <ftbdf.h>
src/base/ftbitmap.c -- optional, see <ftbitmap.h>
src/base/ftcid.c -- optional, see <ftcid.h>
src/base/ftfntfmt.c -- optional, see <ftfntfmt.h>
src/base/ftfstype.c -- optional
src/base/ftgasp.c -- optional, see <ftgasp.h>
src/base/ftgxval.c -- optional, see <ftgxval.h>
src/base/ftlcdfil.c -- optional, see <ftlcdfil.h>
src/base/ftmm.c -- optional, see <ftmm.h>
src/base/ftotval.c -- optional, see <ftotval.h>
src/base/ftpatent.c -- optional
src/base/ftpfr.c -- optional, see <ftpfr.h>
src/base/ftstroke.c -- optional, see <ftstroke.h>
src/base/ftsynth.c -- optional, see <ftsynth.h>
src/base/fttype1.c -- optional, see <t1tables.h>
src/base/ftwinfnt.c -- optional, see <ftwinfnt.h>
src/base/ftmac.c -- only on the Macintosh
-- font drivers (optional; at least one is needed)
src/bdf/bdf.c -- BDF font driver
src/cff/cff.c -- CFF/OpenType font driver
src/cid/type1cid.c -- Type 1 CID-keyed font driver
src/pcf/pcf.c -- PCF font driver
src/pfr/pfr.c -- PFR/TrueDoc font driver
src/sfnt/sfnt.c -- SFNT files support
(TrueType & OpenType)
src/truetype/truetype.c -- TrueType font driver
src/type1/type1.c -- Type 1 font driver
src/type42/type42.c -- Type 42 font driver
src/winfonts/winfnt.c -- Windows FONT / FNT font driver
-- rasterizers (optional; at least one is needed for vector
formats)
src/raster/raster.c -- monochrome rasterizer
src/smooth/smooth.c -- anti-aliasing rasterizer
-- auxiliary modules (optional)
src/autofit/autofit.c -- auto hinting module
src/cache/ftcache.c -- cache sub-system (in beta)
src/gzip/ftgzip.c -- support for compressed fonts (.gz)
src/lzw/ftlzw.c -- support for compressed fonts (.Z)
src/bzip2/ftbzip2.c -- support for compressed fonts (.bz2)
src/gxvalid/gxvalid.c -- TrueTypeGX/AAT table validation
src/otvalid/otvalid.c -- OpenType table validation
src/psaux/psaux.c -- PostScript Type 1 parsing
src/pshinter/pshinter.c -- PS hinting module
src/psnames/psnames.c -- PostScript glyph names support
Notes:
`ftcache.c' needs `ftglyph.c'
`ftfstype.c' needs `fttype1.c'
`ftglyph.c' needs `ftbitmap.c'
`ftstroke.c' needs `ftglyph.c'
`ftsynth.c' needs `ftbitmap.c'
`cff.c' needs `sfnt.c', `pshinter.c', and `psnames.c'
`truetype.c' needs `sfnt.c' and `psnames.c'
`type1.c' needs `psaux.c' `pshinter.c', and `psnames.c'
`type1cid.c' needs `psaux.c', `pshinter.c', and `psnames.c'
`type42.c' needs `truetype.c'
Please consult the central `include/config/ftoption.h'
configuration file for details on additional libraries necessary
for some optional features.
Read the file `CUSTOMIZE' in case you want to compile only a subset
of the drivers, renderers, and optional modules; a detailed
description of the various base extension is given in the top-level
file `modules.cfg'.
You are done. In case of problems, see the archives of the FreeType
development mailing list.
II. Support for flat-directory compilation
------------------------------------------
It is possible to put all FreeType 2 source files into a single
directory, with the *exception* of the `include' hierarchy.
1. Copy all files in current directory
cp freetype2/src/base/*.[hc] .
cp freetype2/src/raster1/*.[hc] .
cp freetype2/src/smooth/*.[hc] .
etc.
2. Compile sources
cc -c -Ifreetype2/include -DFT2_BUILD_LIBRARY ftsystem.c
cc -c -Ifreetype2/include -DFT2_BUILD_LIBRARY ftinit.c
cc -c -Ifreetype2/include -DFT2_BUILD_LIBRARY ftdebug.c
cc -c -Ifreetype2/include -DFT2_BUILD_LIBRARY ftbase.c
etc.
You don't need to define the FT_FLAT_COMPILATION macro (as this
was required in previous releases of FreeType 2).

我已将 "include" 文件添加到我的编译器，但我不确定是否需要 link 任何内容。当我尝试构建所需的文件时，我收到有关预编译 headers 不存在的警告错误。所以我按照安装说明（上面）说的做了，我把它们注释掉了，但是当我试图构建文件时，有一些未定义的变量不允许我构建文件。如果把预编译headers注释掉不是说明中禁用预编译headers的意思。那么如何禁用预编译headers呢？
我想做的就是将 freetype2.6 添加到我的代码块编译器中。我以前从未这样做过，所以感谢您的帮助。谢谢
首先：Code::Blocks 不是编译器。它只是一个 IDE - 一个更复杂的文本编辑器，但仍然只是一个文本编辑器。
我认为你应该从弄清楚你使用的是什么编译器和构建系统以及如何正确使用它们开始。
