從源頭上的Fedora 19構建matplotlib，並沒有發現FreeType的頭文件

Question

我已經安裝在Fedora 19系統上matplotlib源碼包，並得到了以下信息：

============================================================================ 
Edit setup.cfg to change the build options 

BUILDING MATPLOTLIB 
    matplotlib: yes [1.3.1] 
     python: yes [2.7.6 (default, Jan 9 2014, 14:24:42) [GCC 
       4.8.1 20130603 (Red Hat 4.8.1-1)]]` 
     platform: yes [linux2] 

REQUIRED DEPENDENCIES AND EXTENSIONS 
     numpy: yes [version 1.8.0] 
     dateutil: yes [dateutil was not found. It is required for date 
        axis support. pip/easy_install may attempt to 
        install it after matplotlib.] 
     tornado: yes [tornado was not found. It is required for the 
       WebAgg backend. pip/easy_install may attempt to 
       install it after matplotlib.] 
    pyparsing: yes [pyparsing was not found. It is required for 
       mathtext support. pip/easy_install may attempt to 
       install it after matplotlib.] 
     pycxx: yes [Couldn't import. Using local copy.] 
     libagg: yes [pkg-config information for 'libagg' could not 
       be found. Using local copy.] 
     freetype: no [The C/C++ header for freetype2 (ftbuild.h) 
       could not be found. You may need to install the 
       development package.] 
      png: yes [pkg-config information for 'libpng' could not 
       be found. Using unknown version.] 

OPTIONAL SUBPACKAGES 
    sample_data: yes [installing] 
     toolkits: yes [installing] 
     tests: yes [using nose version 1.3.0] 

OPTIONAL BACKEND EXTENSIONS

     tkagg: no [TKAgg requires Tkinter.] 
     wxagg: no [requires wxPython] 
      gtk: no [The C/C++ header for gtk (gtk/gtk.h) could not 
       be found. You may need to install the development 
       package.] 
      agg: yes [installing] 
     cairo: no [cairo not found]

OPTIONAL LATEX DEPENDENCIES 
     dvipng: yes [version 1.14] 
    ghostscript: yes [version 9.07] 
     latex: no 
     pdftops: yes [version 0.22.1] 

============================================================================ 
       * The following required packages can not be built: 
       * freetype 

然而，這種安裝之前，我有已經在默認目錄中安裝了freetype 2.5.2，即/usr/local。我在/usr/local/include/freetype2找到頭文件（ft2build.h）。該setupext.py也檢查，在class FreeType(SetupPackage)代碼部分，有

the default_include_dirs= 
      ['freetype2','lib/freetype2/include','lib/freetype2/include/freetype2',] 

現在

，我不知道爲什麼包找不到安裝的FreeType。有人有一些想法嗎？感謝你的幫助！！！

Answer 1

我有完全相同的問題。我解決了這個問題，只需在self._check_for_pkg_config（）的setupext.py中用ft2build.h的整個路徑替代'ft2build.h'（由tcaswell創建）即可。

Answer 2

感謝您的幫助！

是的，我手動安裝所有這些軟件包，因爲我的電腦與Linux系統donot連接到互聯網。

之前，我發現你的回答道：我已經解決了以間接的方式;-(問題，這裏是我做了什麼：

因爲devel包的FreeType 2.5.2不便於我的Fedora 19系統，所以我不得不選擇使用freetype 2.4.11-6及其開發包，依賴性現在可以，我個人懷疑這是一個環境路徑設置的問題，但我沒有時間在那個時候測試它實際上，freetype 2.5.2的源碼包已經包含了devel子目錄

順便說一句，matplotlib的手動安裝很複雜，排除必須的包：libpng和numpy，你仍然需要安裝distributed ，backports.ssl_match_hostname，龍捲風，六，dateutil和pyparsing。只有在所有這些安裝完成後，matplotlib才能最終安裝到您的系統中。

Answer 3

在Windows 7上使用pip install的cygwin 64上的同樣問題：安裝pkg-config後解決。
