我正在尝试为IMX53 Evk板构建gstreamer。 我从http://freescale.github.io/#download下载了Yocto并运行以下命令。
#MACHINE=imx53qsb
#source setup-environment build
#bitbake core-image-minimal
它构建了u-boot，内核和文件系统。文件系统没有gstreamer。我也想建立gstreamer。
根据我的理解，现在有两种方法来构建gstreamer。
方法1.修改distro.conf文件以构建gstreamer。一世 我不知道如何在distro.conf中添加gstreamer条目。该 分配是一种分配。
方法2.使用gstreamer条目添加IMAGE_INSTALL_append。我的 这里是我们必须在IMAGE_INSTALL_append中添加的名称。
我可以看到以下与gstreamer相关的bb文件。你可以帮助我在local.conf中的IMAGE_INSTALL_append中添加我需要添加的字符串。

您可以添加
IMAGE_INSTALL_append += "gstreamer"
很长的答案是你应该添加通常存储在PN配方变量中的包名。您可以阅读有关PN变量here的信息。包名称也可以使用包variable进行管理。
答案 1 :(得分：1)
你要么用
IMAGE_INSTALL_append = " gstreamer"
要么
IMAGE_INSTALL += " gstreamer"
他们做同样的事情，但使用此变量时IMAGE_INSTALL_append最好。
gstreamer前面的空间非常重要，因为。
让我们说IMAGE_INSTALL是一个字符串："opkg qtbase"
如果我们不在前面添加一个空格。
IMAGE_INSTALL将是这样的："opkg qtbasegstreamer"会导致错误。
答案 2 :(得分：0)
获取包名称的建议是正确的。首先找到食谱。 bitbake-layers对此很有用。然后检查PN和PACKAGES变量是否未设置，如果它们变得棘手的话。对于gstreamer他们不是
如果您是Yocto的新手，我可以在local.conf中添加软件包。输入应该是IMAGE_INSTALL_append + =＆＃34; gstreamer的＆＃34 ;. gstreamer之前的空间很重要。
