Compiler errors 在树莓Pi2上编译libavg

我想在我的新树莓2上构建libavg

我的脚步是

1.) git clone https://github.com/libavg/libavg.git libavg
2.) cd libavg
3.) ./bootstrap
4.) ./configure --enable-rpi --prefix=/home/pi/raspberryPi2/install_release

这会导致一个错误

  CXXLD  testgraphics
  CXX    testgpu.o
  CXXLD  testgpu
  /usr/bin/ld: ./.libs/libgraphics.a(BCMDisplay.o): undefined reference to symbol 'vc_dispmanx_element_add'

有人能帮忙吗？

错误来自修改过的makefile。没有这个文件，libavg构建就正确了。 在修改后的Makefile中，libavg是使用libbrowsernode支持编译的。 有办法吗

修改文件：src/test/plugin/Makefile.am

pkgpyexec_LTLIBRARIES = colorplugin.la libbrowsernode.la
colorplugin_la_SOURCES = ColorNode.cpp
colorplugin_la_LDFLAGS = $(EXTRA_LDFLAGS) -module
libbrowsernode_la_SOURCES = BrowserNode.cpp
libbrowsernode_la_LDFLAGS = -lberkelium_delegate $(EXTRA_LDFLAGS) -module

组织。文件：

pkgpyexec_LTLIBRARIES = colorplugin.la
colorplugin_la_SOURCES = ColorNode.cpp
colorplugin_la_LDFLAGS = $(EXTRA_LDFLAGS) -module

需要更新libavg以与当前RPi系统一起运行。这个问题在libavg的当前git头中得到了修复，因此您只需要执行git拉取和重新编译

必要的更改如下：

尝试在makefile中添加-lbcm\u主机？？哪个LIBS变量？还是在配置步骤中？
