Compilation 使用新的glib版本编译gstreamer

我已经安装了CentOS 6.7。我需要编译gstreamer1.4.5（或任何1.x），因为CentOS发行版有gstreamer0.10。GStreamer 1.x需要GLib2>=2.32左右，但CentOS需要2.28.8。因此，我使用特定位置/usr/mylibs（as--prefix-param）编译了Glib2.44.1

现在我正在尝试编译GStreamer 1.4.5：

export GLIB_CFLAGS="-I/usr/mylibs/include/glib-2.0 -I/usr/mylibs/lib/glib-2.0/include" && export GLIB_LIBS="-L/usr/mylibs -L/usr/mylibs/lib/glib-2.0" && export GIO_CFLAGS="-I/usr/mylibs/include -I/usr/mylibs/include/gio-unix-2.0" && export GIO_LIBS="-L/usr/mylibs -L/usr/mylibs/lib/gio" && export PYTHON=/usr/mylibs/bin/python
./configure --prefix=/usr/mylib
or
./configure 
make

它会一直工作，直到出现以下错误：

我错过了什么？请帮助。

您似乎误解了

*\u LIBS

环境变量的工作原理。它应该包含链接到glib所需的标志；类似于“-L/usr/mylibs/lib-lglib-2.0”的东西应该可以工作

---

-L…标志为链接器提供了一个额外的位置来查找共享库（即，

libglib-2.0.so

），但在您的标志中，您为链接器提供了一个位于其所需目录之上的目录（/usr/mylibs）和一个子目录（/usr/mylibs/lib/glib-2.0）。-l…标志告诉它要查找哪个特定库，但您完全忽略了它。

我在CentOS 6.3虚拟机上遇到了相同的问题。我试图针对glib 2.32.4构建GStreamer 1.4.5。如中所示，当您尝试构建（而不是2.0版本！）时，似乎链接了不正确的库，而不是在GLIB\u CFLAGS中显式定义目录路径，您可以使用PKG\u CONFIG\u PATH

找到pkgconfig目录并确保您安装的软件包驻留在其中（如glib-2.0、gobject-2.0、gthread-2.0等）（在我的计算机上，我的路径是：

/usr/local/lib/pkconfig/

），我注意到在您的目录列表中，您提供了确实有pkgconfig的软件包

首先，导出变量，然后配置，最后生成：

export-PKG\u-CONFIG\u-PATH=/usr/mylibs/lib/pkgconfig/
/配置
制造

GStreamer现在应该正确构建
