GST-OMX插件生成错误：数组 '_GStaticAssertCompileTimeAssertion_1' 的大小为负

Question

我的构建ENV：

gst-omx Version: Tag 1.11.2 
OS Description: Ubuntu 16.04.2 LTS 64bit 
Cerbero version: Tag 1.11.2 

之前构建GST-OMX，我已经成功地构建GStreamer的SDK 1.0标签1.11.2与目标android_arm

GST-OMX build命令：

$./autogen.sh --host=arm-linux-androideabi --disable-gtk-doc --with-omx-target=generic --enable-static --prefix=/home/leon/tools/cerbero/omx --enable-static-plugins --disable-fatal-warnings 
$make 

然后我得到了错误信息：

gstomxbufferpool.c: In function ‘gst_omx_memory_allocator_get_type’: 
/home/leon/tools/cerbero/build/dist/android_arm/include/glib-2.0/glib/gmacros.h:232:53: error: size of array ‘_GStaticAssertCompileTimeAssertion_1’ is negative

这个问题可能位于 G_STATIC_ASSERT (sizeof *(location) == sizeof (gpointer));

我在cerbero build文件夹中检查了glib库， '位置' 反映了&g_define_type_id_volatile。

原始定义是static volatile gsize g_define_type_id_volatile = 0;和类型定义是：

gtypes.h(77): typedef void* gpointer; 
glibconfig.h(60): typedef unsigned int gsize; 

但我不知道发生了什么事情，以及如何避免这个问题。 有人能帮助我吗？非常感谢！

我认为这可能是由于识别正确的工具链的失败，为配置显示：

从由箭头标记的位置，我怀疑NDK工具链无法识别。所以它使用本机64位gcc编译器作为替代，这些类型的大小不能匹配。

我的结论是否正确？

如果是正确的，如何让gst-omx知道工具链在哪里？ 感谢大家〜

Answer 1

我自己解决了这个问题。

这是正确的，这是工具链的问题，但{ndkroot}/toolchain中的工具链不能直接使用，否则会出现各种编译错误。

首先，我做我自己的工具链与NDK提供的工具：

cd ~/tools/android-ndk-r13b/build/tools/ 
./make-standalone-toolchain.sh --platform=android-21 --install-dir=/home/leon/tools/android-toolchain --toolchain=arm-linux-androideabi-4.9 

其次我添加新的crosstool路径ENV，使配置找到它：

export PATH=/home/leon/tools/android-toolchain/bin:$PATH 

最后修改配置参数：

./autogen.sh --host=arm-linux-androideabi --disable-gtk-doc --with-omx-target=generic --enable-static --prefix=/home/leon/tools/cerbero/omx --enable-static-plugins --disable-fatal-warnings PKG_CONFIG_PATH=/home/leon/tools/cerbero/build/dist/android_arm/lib/pkgconfig --with-sysroot=/home/leon/tools/android-toolchain/sysroot 
make & make install 

最终，gst-omx插件文件将在/home/leon/tools/cerbero/omx
