在Raspberry Pi2上编译libavg

Question

我想在我的新RaspberryPi2上构建libavg。

我的步骤是，

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 

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' 
    //opt/vc/lib/libbcm_host.so: error adding symbols: DSO missing from command line 
    collect2: ld returned 1 exit status 
    Makefile:668: recipe for target 'testgpu' failed

    make[1]: Leaving directory '/home/pi/raspberryPi2/libavg/src' 
    Makefile:389: recipe for target 'all-recursive' failed 
    make: *** [all-recursive] Error 1 

任何人都可以帮忙吗？

Answer 1

错误来自修改后的makefile。没有这个文件，libavg build就是正确的。 在修改后的Makefile中，libavg与libbrowsernode支持一起编译。 有没有办法做到这一点？

修改的文件：源/测试/插件/ 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 

有机文件：

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

libavg需要更新以与当前RPi系统一起运行。这个问题在当前libavg的git头文件中得到解决，所以你只需要做一个git pull并重新编译。

的变化需要在这里：https://github.com/libavg/libavg/commit/d7f785347c90ada2daf02afffaac178bb705607b
