在fedora 19上從源代碼構建matplotlib,未找到freetype頭文件

[英]building matplotlib from source on fedora 19, and found no freetype header files

我已經在fedora 19系統上安裝了matplotlib源程序包,並獲得了以下信息:

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

BUILDING MATPLOTLIB
    matplotlib: yes [1.3.1]

                     install it after matplotlib.]
       tornado: yes [tornado was not found. It is required for the

                could not be found. You may need to install the
                development package.]

                be found.  You may need to install the development
                package.]
           agg: yes [installing]

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

但是,在此安裝之前,我已經在默認目錄(即/usr/local安裝了freetype 2.5.2。 我在/usr/local/include/freetype2找到了頭文件( ft2build.h )。 還檢查了setupext.py ,在class FreeType(SetupPackage)的代碼部分中,有

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

現在,我不知道為什么軟件包找不到已安裝的freetype。 有人有想法嗎? 感謝你的幫助!!!

我有完全一樣的問題。 我解決了這個問題,只需在self._check_for_pkg_config()中的setupext.py中用我的ft2build.h的整個路徑(由tcaswell建議)替換ft2build.h即可。

感謝您的所有幫助!

是的,我手動安裝所有這些軟件包,因為我的Linux系統電腦無法連接到互聯網。

在我找到您的答復之前,我已經以間接方式解決了問題;-(,這是我所做的:

由於freetype 2.5.2的devel軟件包對我的fedora 19系統而言並不方便,因此我不得不選擇使用freetype 2.4.11-6及其devel軟件包,現在的依賴關系還可以。 我個人懷疑這是環境路徑設置的問題,但當時我沒有時間對其進行測試。 實際上,freetype 2.5.2的源包已經包含devel子目錄。

順便說一句,matplotlib的手動安裝非常復雜,排除了必備軟件包:libpng和numpy,您仍然需要安裝distribution,backports.ssl_match_hostname,tornado,six,dateutil和pyparsing。 只有在所有這些安裝都結束之后,才能最終將matplotlib安裝在您的系統中。

使用pip install在Windows 7上的cygwin 64上存在相同的問題:在安裝pkg-config后解決。
