使用新的glib版本编译gstreamer

标签： compilation gstreamer centos6 glib

我安装了CentOS 6.7。我需要编译GStreamer 1.4.5（或任何1.x），因为CentOS发行版有GStreamer 0.10。 GStreamer 1.x要求GLib2> = 2.32左右，但CentOS有2.28.8。因此，我使用特定位置/ usr / mylibs（作为--prefix param）编译了GLib 2.44.1。

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

直到出现此错误：

我错过了什么？请帮忙。

您似乎误解了Function JumpToLine(LnNum as String) GoTo LnNum End Function 环境变量的工作原理。它应该包含链接到glib所需的标志;像＆＃34; -L / usr / mylibs / lib -lglib-2.0＆＃34;应该工作。

-L ...标志为链接器提供了一个额外的位置来查找共享库（即，*_LIBS），但在你的标志中，你已经给它一个目录了它需要什么（/ usr / mylibs）和一个子目录（/usr/mylibs/lib/glib-2.0）。 -l ...标志告诉它要查找的特定库，但是你完全省略了它。

我在CentOS 6.3 VM上遇到了同样的问题。我试图针对glib 2.32.4构建GStreamer 1.4.5。如this message thread所示，当您尝试构建时（而不是2.0版本），似乎链接了不正确的库！而不是在GLIB_CFLAGS中显式定义目录路径，您可以使用PKG_CONFIG_PATH。

找到pkgconfig目录并确保已安装的软件包驻留在那里（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/。）我注意到了在您提供的目录列表中，确实有pkgconfig。

首先，导出变量，然后配置，最后制作：

export PKG_CONFIG_PATH=/usr/mylibs/lib/pkgconfig/ ./configure make

GStreamer现在应该正确构建。
