android - 为 Android NDK 构建 Pango Cairo

Question

我发现有人为 Android NDK(blog post，source code)移植了 Pango Cairo。但是我没有成功编译他的示例项目。有没有人设法这样做并且可以告诉我我做错了什么？

这是我目前尝试过的:

• git clone --recursive http://dev.laptop.org/git/users/cscott/android-libs/
• git 出于某种原因找不到 pixman，git clone http://cgit.freedesktop.org/pixman/ 也是如此。 ，并移动到 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
• 编辑 java-bitmap/jni/Makefile 如下:NDK=/cygdrive/f/android-ndk-r8bTOOLCHAIN=$(NDK)/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin
• 尝试在 java-bitmap/jni 中运行 ma​​ke

我收到以下错误:

这是 config.h 的一个 fragment

我更进了一步。

代替

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

我下载了

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

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

/tmp/cc2XOCMj.o:(.ARM.exidx.text.main+0x0): undefined reference to `__aeabi_unwind_cpp_pr0'.

但这可能是由 this same problem 引起的
