为Android NDK构建Pango Cairo

Question

我发现有人在Pango Cairo上移植了Android NDK（博客文章，源代码）。但是，我在编译他的示例项目方面还没有成功。有没有人设法做到这一点，并且可以告诉我我做错了什么？

到目前为止，这是我尝试过的：

• git clone-递归http://dev.laptop.org/git/users/cscott/android-libs/
• git由于某种原因找不到pixman，因此git clone http://cgit.freedesktop.org/pixman/并移至android-libs / jni / pixman
• 将android-libs / jni /的内容复制到android-libs / examples / java-bitmap / jni（不确定要保留哪个Android.mk？）
• 将java-bitmap / jni / Makefile.devel重命名为Makefile
• 如下编辑了Java位图/ jni / Makefile：NDK = / cygdrive / f / android-ndk-r8b TOOLCHAIN = $（NDK）/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin
• 试图在java-bitmap / jni中运行make

我收到以下错误：

这是config.h的片段

我又更进了一步。

代替

git clone http://cgit.freedesktop.org/pixman/

我下载的是

git clone --recursive http://dev.laptop.org/git/users/cscott/android-pixman

并将所有文件复制到空jni/pixman目录中。现在找到了文件pixman-elf-fix.h，但链接器失败并显示：

/tmp/cc2XOCMj.o:(.ARM.exidx.text.main+0x0)：对“__aeabi_unwind_cpp_pr0”的未定义引用。

但这可能是由同样的问题引起的
