在pkg-config搜索路径中找不到包cairo

Question

在Mac OS X 1.7.5/Lion上

我正在尝试使用自制软件安装cairo包

brew install cairo => PASSED

==> Downloading http://cairographics.org/releases/cairo-1.12.16.tar.xz
Already downloaded: /Library/Caches/Homebrew/cairo-1.12.16.tar.xz
==> ./configure --prefix=/usr/local/Cellar/cairo/1.12.16 --with-x --enable-gobject=yes
==> make install
==> Caveats
This formula is keg-only: so it was not symlinked into /usr/local.

Mac OS X already provides this software in versions before Mountain Lion.

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/cairo/lib
    CPPFLAGS: -I/usr/local/opt/cairo/include

==> Summary
  /usr/local/Cellar/cairo/1.12.16: 105 files, 8.0M, built in 2.5 minutes

当我尝试编译我的代码时,我仍然得到这个:

+++ Precompile
Package cairo was not found in the pkg-config search path.
Perhaps you should add the directory containing `cairo.pc'
to the PKG_CONFIG_PATH environment variable
Package 'cairo', required by 'pangocairo', not found

所以我相应地调整了我的PKG_CONFIG_PATH

 PKG_CONFIG_PATH=/usr/local/opt/cairo/lib/pkgconfig/:/usr/local/lib/pkgconfig:/usr/X11/lib/pkgconfig/:

(来源.bash_profile)

试图再次编译,但我得到完全相同的错误.

验证该文件存在于该pkgconfig目录中......它是.

ls /usr/local/opt/cairo/lib/pkgconfig/ 
cairo-fc.pc           cairo-gobject.pc      cairo-png.pc          cairo-quartz-font.pc  cairo-script.pc       cairo-xcb-shm.pc      cairo-xlib-xrender.pc cairo.pc
cairo-ft.pc           cairo-pdf.pc          cairo-ps.pc           cairo-quartz.pc       cairo-svg.pc          cairo-xcb.pc          cairo-xlib.pc

这里出了什么问题导致什么？

UPDATE

cairo.pc位于我系统的太多位置.我尝试在我的pgg配置路径中使用每个位置但没有成功

find /usr -name cairo.pc 
/usr/local/Cellar/cairo/1.12.16/lib/pkgconfig/cairo.pc
/usr/X11/lib/pkgconfig/cairo.pc

pkg-config --variable pc_path pkg-config
/usr/local/lib/pkgconfig:/usr/local/share/pkgconfig:/usr/lib/pkgconfig

Answer 1

注意:仅适用于Ubuntu.

解决我的问题更容易.Ubuntu依赖项未正确安装,您可以在此处找到说明:

这对我有用:

sudo apt-get install libcairo2-dev libjpeg8-dev libpango1.0-dev libgif-dev build-essential g++

Answer 2

ln -s /usr/local/Cellar/cairo/1.12.16/lib/pkgconfig/cairo.pc /usr/local/lib/pkgconfig/cairo.pc

解决了我的问题
