【问题描述】：
我正在尝试在 CentOS 5 服务器上安装 pango-1.36，我没有 root 访问权限，因此必须安装到非标准位置。我已经下载了源代码，但是当我尝试运行./configure 时，我收到以下错误消息：
checking which cairo font backends could be used... none
configure: Disabling cairo support
configure: error: *** Could not enable any backends.
*** Must have at least one backend to build Pango.
当我深入了解config.log 时，我看到了这个：
configure:18613: $PKG_CONFIG --exists --print-errors "cairo-quartz-font >= $cairo_required"
Package cairo-quartz-font was not found in the pkg-config search path.
Perhaps you should add the directory containing `cairo-quartz-font.pc'
to the PKG_CONFIG_PATH environment variable
No package 'cairo-quartz-font' found
configure:18616: $? = 1
configure:18631: checking which cairo font backends could be used
configure:18640: result: none
configure:18642: Disabling cairo support
configure:18793: error: *** Could not enable any backends.
*** Must have at least one backend to build Pango.
我不确定为什么 pango 特别需要 cairo-quartz-font。当我安装 cairo 时，我启用了 Fontconfig，这似乎有效：
# in cairo source directory
./configure --prefix=/some/custom/path --enable-fc
# lots of output, just showing summary
cairo (version 1.14.2 [release]) will be compiled with:
The following surface backends:
Image: yes (always builtin)
Recording: yes (always builtin)
Observer: yes (always builtin)
Mime: yes (always builtin)
Tee: no (disabled, use --enable-tee to enable)
XML: no (disabled, use --enable-xml to enable)
Skia: no (disabled, use --enable-skia to enable)
Xlib: yes
Xlib Xrender: yes
Qt: no (disabled, use --enable-qt to enable)
Quartz: no (requires CoreGraphics framework)
Quartz-image: no (disabled, use --enable-quartz-image to enable)
XCB: no (requires xcb >= 1.6 xcb-render >= 1.6 http://xcb.freedesktop.org)
Win32: no (requires a Win32 platform)
OS2: no (disabled, use --enable-os2 to enable)
CairoScript: yes
PostScript: yes
PDF: yes
SVG: yes
OpenGL: no (disabled, use --enable-gl to enable)
OpenGL ES 2.0: no (disabled, use --enable-glesv2 to enable)
BeOS: no (disabled, use --enable-beos to enable)
DirectFB: no (disabled, use --enable-directfb to enable)
OpenVG: no (disabled, use --enable-vg to enable)
DRM: no (disabled, use --enable-drm to enable)
Cogl: no (disabled, use --enable-cogl to enable)
The following font backends:
User: yes (always builtin)
FreeType: yes
Fontconfig: yes
Win32: no (requires a Win32 platform)
Quartz: no (requires CoreGraphics framework)
The following functions:
PNG functions: yes
GLX functions: no (not required by any backend)
WGL functions: no (not required by any backend)
EGL functions: no (not required by any backend)
X11-xcb functions: no (disabled, use --enable-xlib-xcb to enable)
XCB-shm functions: no (requires --enable-xcb)
The following features and utilities:
cairo-trace: yes
cairo-script-interpreter: yes
And the following internal features:
pthread: yes
gtk-doc: no
gcov support: no
symbol-lookup: no (requires bfd)
test surfaces: no (disabled, use --enable-test-surfaces to enable)
ps testing: no (requires libspectre)
pdf testing: no (requires poppler-glib >= 0.17.4)
svg testing: no (requires librsvg-2.0 >= 2.35.0)
所以看起来 cairo 启用了几个不同的字体后端，包括 Fontconfig。 pango 需要cairo-quartz-font 吗？有没有办法让它也可以使用 Fontconfig？任何帮助将不胜感激，如果我可以提供其他信息，请告诉我。非常感谢。
