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

这会导致错误。

有人可以帮忙吗？

libavg 需要更新才能与当前的 RPi 系统一起运行。该问题已在 libavg 的当前 git head 中修复，因此您只需执行 git pull 并重新编译即可。

必要的更改在这里：https ://github.com/libavg/libavg/commit/d7f785347c90ada2daf02afffaac178bb705607b

错误来自修改后的 makefile。没有该文件，libavg 构建正确。在修改后的 Makefile 中，libavg 是在 libbrowsernode 支持下编译的。有没有办法做到这一点？

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
